Drop in Sync Speed

Over the past few weeks I've seen a drop off in the Sync speed of my broadband and the Noise margin increase from 6dB to 8.5 dB.
I was connecting at 6Mbps but now it has dropped to 4.5Mbps - is there anything that I can do to get it back to what it was?
Everything has been fine with the connection itself - it has been rock solid in that it hasn't been disconnecting.

Looks like your target margin has moved from 6db to 9db, this is the values that equates to the initial noise margin needed for a stable sync.
You need to contact the mods on this site (click on one of their profiles for the link to them) and ask to have the targer margin reduced.
They may want to see a period of stable connection first but it is worth contacting them now since it takes them 3 days to reply normally.
A 9db target margin should give more line stability so unless you know what the problem was that caused it to increase (normally a series of resyncs, the default being 10 in 60 minutes) then you may want to check for a line problem first since otherwise if it is set to 6 it may go back to 9 again because of an underlying issue.

  • Continual Drop in Sync Speed

    I have been experiencing a continual drop on sync speed and thus actual line speed over the last few weeks. I had a HH4 replaced aftger teh last one died and since then the line speed seems to be getting slower and slower.
    I am on DSLMax (good old ADSL) and normally sync around 8mb as am very close to the actual exchange - am now down to 6.4mb and am sure it will drop again.
    Normal instructions from the phone support has been applied - reset hub etc.... and has not made a difference...
    Can I ask one of the mod's to try and help out - see why the line is syncing lower than it normally does/has been for the last 3 years....
    thanks
    Pete

    in order for the forum members to help please can you post the adsl stats from your router you may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or if HH4/5 then go to troubleshooting then logs and you are looking for 2 line together when hub last connected to internet and they will show your connection speed and noise margin or if netgear enter 192.168.0.1). Then run  btspeedtester  (MAC users may have problems). when first test completes then run diagnostic test and post the results ( do not reset the router).
    are you connected directly via a filter to the NTE5 master or test socket or to somewhere else? Is the master the only phone socket in your home?
    Have you tried the quiet line test? - dial 17070 option 2 - should hear nothing - best done with a corded phone. if cordless phone you may hear a 'dull hum' which is normal
    Someone may then be able to offer help/assistance/suggestions to your problem

  • Big drop in sync speed

    Hi
    I wonder if some one can help, about 10 days ago i had a big drop in downstream sync speed from 5000-6000 to 288
    BT have tested the line twice, and the second engineer has rebalanced the line, but i'm still stuck at the same sync speed
    my IP profile from the speed tester was 250

    So do i reboot the router to see if the connection speed improves, or is their another problem ?
    As additional information  i have only 1 phone socket (the master) and no extensions, nothing has been changed in the set-up and all has been fine for years.
    thanks

  • I think my sync speed is stuck or been capped

    Hi everyone, last week i had a full line reset because i started dropping in speed, from 16meg al the way down to 9meg, at the time time of the reset my sync speed went to 12.5meg, 24 hours later i was down to 9.494meg down and 1.12 up, im supposed to be on another 10day training but nothing has happened, meaning the hhb3 hasnt switched off or resynced since i dropped to 9.4meg, now after 5 days of constant connection there was still no change so i did a something to try and make my speed drop but nothing happened, it still synced at the exact same speed 9.4meg, im certainly not rate adaptive and i cant have any line issues or my speed would of dropped after constantly plugging in and out the socket and making it resync, so the only things i can come up with is that ive either been capped or the exchange has got stuck for some reason, ive even gone through my entire extension wiring and changed it to cat6, it made my line attenuation lower but no change in sync rate heres my speed test and hub stats.

    Thanks for your replys, believe it or not my line as been more stable, meaning alot less disconnects,infact very rare since i last had the snr reset, it auto changed to fast when mods manually reset the snr a month ago, i think it sounds like a joint or something, def not my internal wiring, its all brand new as of today and theres no change in sync so, the prob lies else where, i tried to tell bt before that theres some kind of fault between the pole and the exchange last time my speed dropped when i was on adsl max, it dropped to 300k i think, i rang up for a mac code because they wouldnt acknoweldge the fact and gottalked into adsl2+, everything went well untill 3 weeksago(around that time) i was up to 16meg sync, i posted it on here, after opening my big mouth my speed started to drop so i had a manuall snr reset, that solved it for a while, then i had that bad weather and it all screwed up, like i said previous, about 10-20mins before the reset my sync dropped to 1meg and line attenuation shot up to 65db, after the reset i had 12.5meg, 24 hours later i was down to 9meg, person on the other end of the phone at bt said my minimum sync should be around 12meg

  • Questions and answers on DLM, sync speed and real ...

    I was confused about some DML details and posted on a BE forum (https://avatar.bethere.co.uk/forum/viewtopic.php?t=43542) and got what was to me an incredibly helpful response from Tom (drsox).  I thought it would be of interest to some readers here so copy it below.  Once again, many thanks Tom.
    1) FTTC DLM applies only between the cabinet and the modem? 
    >> Yes, as there isn't any broadband / data signal going anywhere further down the line to the exchange if you are on FTTC! 
    2) What are the different parameters that apply on this hop? I know there is a current sync speed, a current snr, a target snr and an ip profile. Anything else? 
    >> The IP profile isn't really related to DLM, it just "follows" your sync rate. In the past the IP profile would take up to 3 days to "follow upwards", leaving you with a high sync and awful speeds! This has been changed now on 21cn and "RE-ppp"ing (rebooting the router) would force the IP Profile to update instantly. 
    DLM changes the SNR target. So where BE have hard coded / set SNR targets such as 3db, 6db, 9db, 12db etc.. They only change upon user request. BT use their DLM system where line instability or line error counts are collected and analysed, the SNR target and interleaving settings are then modified in increments to try and stabilise the line. 
    This image shows quite well how, over a 6 day period, BTs DLM noticed that my line fault was fixed. I didn't get the full speed back for a week. 
    3) Is the ip profile the same as the BRAS profile? 
    >>Yes 
    4) The DLM keeps statistics of errors etc to dynamically change the ip profile? 
    >> Changes the SNR target and interleaving for the line which will reduce the speed, and therefor the IP profile. 
    5) There is a general theory that the DLM is incapable of telling the difference between an error and a modem power cycle, so that power cycling can cause your profile to lower. Is that correct? 
    >> Yes, if you resync / power cycle your router multiple times in a day it is likely to try and "combat the line errors" and reduce your sync rate by increasing the SNR and / or interleaving on the line. 
    6) Can other connections and disconnections have the same effect? For example, if I reboot the router (where this is separate from the modem)? Or use the router interface to disconnect/reconnect the broadband? 
    >> PPP drops (router reboots while leaving the BT Openreach VDSL modem on and connected) won't affect DLM. The IP profile will match your sync rate upon reconnection of the PPP session. 
    7) If you have a low ip profile, does this mean that the sync is limited to the ip profile? 
    >> Other way around, if you have a low sync rate then the IP profile will match the sync rate. If you get an awful sync rate and the IP profile follows downwards, then you resync higher but the router "keeps the PPP session open" (which is possible if you resync quick enough) then your IP profile will stay low, even though the sync is high. Until you reboot your router or disconnect and reconnect the PPP session. 
    8) Can the sync rate change dynamically without a reconnection? If the ip profile gradually rises, will the cabinet force a resync to make sure the customer is actually getting the benefit of the higher ip profile, or must the user intervene with a modem resync? 
    >> See above - Sync can rise without affecting the IP Profile and the cabinet does not force a RE-PPP. 
    8) As I understand it, if the ip profile gets stupidly low for some reason, it can only be reset by BT wholesale? This will only be done after a visit to your home and a telephone call from the engineer to the BT wholesale central admin? 
    >> Mixed reports plus I don't think people understand the difference between sync speeds, line faults, the delay in DLM increasing sync after a fault.. I expect half the reports on the BT forum are not related to a stuck BRAS / IP profile. It is possible for the ISP or a BT engineer to reset the IP profile and possibly DLM training. 
    9) (8) This applies to all ISPs using BT Wholesale: some may be more willing to force this process to happen on behalf of their customers, but none can cirumvent it? 
    >> GEA providers (I believe) still have DLM but don't have BRAS / IP profiles unless they implement their own. 
    10) Who sets the snr? As I understand it, the customer has no direct control. Is this different for different ISPs? 
    >> Mixed information again, I believe that BT Wholesale give providers DLM override controls and SNR settings but none? (or few) ISPs use this system. 
    11) Real download/upload speeds are physically limited by the sync rate. They are also naturally limited by local limitations (such as wireless connections), server limitations, and congestion at various points along the route? Any more? The congestion along the route will vary bewteen ISPs as they use different routes with different capabilitues. 
    >> It is possible for BTs regional or local cabinet network to become congested. Supposedly the minimum speed you should achieve over the BT part of the network is 15mbps. ISPs such as Plusnet, BT etc.. then layer their own "discriminatory" traffic management on top of that (ie, slow down torrents etc.). 
    12) Real speeds are 'unnaturally' limited by throttling. This will also vary from ISP to ISP. Sky claims to have none, and BT none except for p2p. PlusNet and John Lewis have significant (but well explained)throttling. All the more expensive operators have none. 
    >> What you said  
    13) The ip profile affects the sync rate, and therefore actual speeds. Does the ip profile effect actual speeds in any other way? 
    >> Not quite right. The IP profile directly affects the speeds you can achieve but the sync rate affects the IP profile. The sync rate is determined by the stability and quality of your line and what DLM thinks it can cope with. 
    14) Many people (including AndrueC above) report real speeds from speedtests that are consistent and not close to the ip profile. These can't be explained by congestion (that would make them inconsistent). They can't be explained by server limitations, as they are consistent accross servers and the same servers give better speeds to other people. They can't be explained by local limitations, too many people claim sudden drops where the local conditions have not changed. They should not be able to be explained by throttling, as they as seen for many ISPs who do not throttle (I don't hold with the ISP lying theory here). What other factors are there that can explain these cases? 
    >> AndrueC and some other Sky customers have strange symptoms where speeds are around 20mbps rather than the full sync speed. The only logical explanation is either local cabinet congestion, contention between BT and the provider's network (not enough investment by the provider) or artificial traffic management on the providers side. It is also possible that the router that the customer has attached to their line is unsuitable for the higher speeds. For example an old ethernet router may only be able to cope with 20 or 30mbps! A friend of mine has a TP-Link ethernet router running Tomato on a BT 80mbps service but the TP-Link's CPU limitation causes his service to only perform at around 68mbps; he has a replacement router on order. (Obviously wifi will significantly reduce performance). 
    15) If you get a stupidly low ip profile, how long can you except it to take before it climbs to something more reasonable? (eg in my particular case, my profile is currently around 15Mb, and from BT service line tests should be around 58Mb). And the classic question, is it best to power cycle the modem (1) never, (2) occasionally (how often) or (3) never if at all possible? Mine did jump from 3.5Mb to 15Mb on one power cycle. Was that just coincidence? 
    >> My FTTC line took about 6 to 7 days to go from 40mbps to 80mbps after a line fault. It is possible that your 3.5mbps to 15mbps increase was the "re-ppp" affecting the BRAS profile and that your sync had slowly been increasing over time. 

    what a waste of money sending an engineer to "fix a fault" which does not exist.  Precisely.
    In my original BE post to which Tom so helpfully responded, I began:  It seems to me that DLM is an excellent concept with a highly flawed implementation, both technically and administratively.   I think that sending out an engineer to fix an obviously flawed profile is the main example of an adminastrative flaw.  I understand (I can't remember source, maybe Tom again) that they are sometimes relaxing the requirement for a visit before reset.
    Maybe the DLM system is too keen on stability vs speed.  This will keep complaints down from many people: most users won't notice speed too much as long as it is reasonable, but will be upset if their Skype calls and browsing are being interrupted too often.  
    However, it does lead to complaints from people who notice the drops after an incidence (as in your thread that has drawn lots of interest), or who only get 50 instead of 60.  The main technical flaw is that DLM can so easily be confused by drops from loss of power, too much modem recycling, etc, and then takes so long to recover.

  • Home Hub 3 with low sync speed

     Excuse a newbie who's somewhat jealous of people complaining how they only get 8Mbps!
    A combination of factors means that for months I have been getting a sync of 2624-3040, which equates to a profile of 2000-2500 and resultant download speeds of 1650-2250 using my old Voyager 2091. Then about a year ago, after fitting an I-plate etc. etc. I was achieving fairly consistent downloads at 2200 - so I asked for BT Vision. I can't comment on it, because almost immediately my download speed dropped and my profile was set back to 2000 so Vision was a waste of space. This didn't correct over time, so at the end of September I called up and an engineer came to test my line, swapped me to a new pair due to earthing issues and said I might want to replace my trusty old voyager. All this disruption still had negligible effect, so around Xmas I obtained a Home Hub 3.
    Bad to worse - in the last week I have had to reboot the HH3 at least 5 times (so I'll never get to the end of my BRAS training period) and whereas before I could watch Iplayer etc. 95% of the time, now it seems incapable of streaming for more than half an hour, before the speed drops below an acceptable limit. I'm close to junking the HH3 and going back to the Voyager.
    Is this normal? I've read about the HH3 dropping speeds on contention - am I seeing the issue because this makes my speed unusable? (A drop of 1Mb on an 8Mb speed might be annoying, but for me it's fatal!) or do I have a rogue hub .... in which case, what do I do?

    Results fresh in as you'll see - internet froze again 20 minutes ago and forced ANOTHER reboot.
    With regards to your standard questions - as you'll see from my earlier post, I had a BT engineer in with me for over 4 hours in September, so all the "normal" tests were done, internal wiring checked, quiet line test was done from the master socket, he even swapped me to a new pair with better earth. There are 3 extension and the NTE5, all filtered. .... oh and neighbours with another provider achieve 2K+ constantly.
    I am not now connected to the NTE5, but the engineer cut the bell wire and it has an I-Plate anyway (belt & braces!). During tests with him and for 3 weeks after (without a reboot) the router was connected directly to the master socket and it made no difference, except weakening the wireless signal to my office. So I am again connected to my office extension socket, as before, and the move had no discernable effect on sync since October.
    So I'm not really expecting much on sync,  live in a rural area, 2.5 clicks from the exchange (ADSL/POTS) but have a line length of over 4Km using the normal calcuation, probably with lovely aluminium along the way.
    I'm just gobsmacked that the new Hub appears to be unfit for purpose, drops the download speed at the drop of a hat and freezes up on a regular basis .... so this is my final fling before jacking it and probably joining my neighbours with a provider who CAN offer an improvement.

  • Massive drop in line speed...

    Hi all,
    I suffered a massive drop in Internet connection speed earlier this week which has so far not improved.
    Although I have had ADSL since it's near earliest days and being close to my exchange I have never received a great performance but have become more or less satisfied with the 4\4.5mbps I receive from my Total Broadband Option3 package.
    I did receive close to that speed prior to the 8mb upgrade a few years back and an upgrade to 20mbps doesn't promise me any better (availability checker for neighbours etc suggests that faster is available but who is to know?).
    On Wednesday (9th February) my connection\synch speed dropped to about half it's usual speed and is now in the region of 240kb rather than the near 500kb I usually receive. I would like to comment that I know my line can achieve better than this as I got download speeds of nearer 600kb for a month or so around October last year.
    I power-cycled the router and after the diagnostics had completed etc and the line synch process had  completed the speed of the line had dropped again slightly.
    Not to sound arrogant but I know all the usual troubleshooting having been through it all before on several occasions each time finding out the issue is with the exchange and so having had no means to affect the problem.
    The situation is the same this time in that categorically nothing has changed inside my home nor with my equipment and so I am confident that the problem is external to me, especially considering the massive drop in speed.
    I did get a response from a BT forum moderator from a post I placed on another site but the advise I got back was generic at best and didn't suggest anything besides mounting a BT iPlate. that advice was no good for two reasons which are that as nothing in my home has changed fitting an iPlate won't make a 2+mbps connection increase (back to what it was) and that I already have an 'ADSL v1.0' labelled master socket that already contains all the tech that the iPlate does. Having replied to their email stating that I already have the afore mentioned v1.0 master socket I haven't had any response.
    So... to explain further...
    here are some diagnostic stats for the past couple of days taken from my router (Draytek Vigor 2820n) - sorry the font is small bu tI wanted to keep the layout of the text when I completed the post;

    The BT Speed Tester web-site reports my line speed as 2mbps when it was previously 4.5mbps and so as to check actual download speed independently I ran a comparison speed test via SpeedTest.Net which reported much the same result (down\up speed relative to what you would expect for a 2mbps line - Link to SpeedTest.Net results: http://www.speedtest.net/result/711802566.png ).
    As you can see from the diagnostic data, the SNR is high and so it does seem to suggest that there is fault on the line. prior to the fault, the SNR was around 6db rather than the 15\16db reported now.
    I know it has little factual baring on this incident's potential problems but my last broadband speed issue was caused by water having gotten into the top of the telephone pole at the end of my street which was temporarily fixed by a BT engineer but I don't know whether that was ever permanently fixed?
    During that occasion I did suffer very slight noise on my telephone line which I must say isn't the case this time but I thought I would request a line test once again in any case. That unfortunately hasn't helped as the online system tells me 'telephone number not found' and so I can't proceed with the test.
    Can anyone offer any advice or is any BT person willing to take on the issue and see it to resolution for me please?
    Even trying my own diagnostics trying to speed things along by obtaining a line test hasn't been possible.
    I do appreciate that there is a support system in place but that has failed me on this occasion and so I have no faith in going throught the telephone support for BT Broadband when I know that nothing I can affect is at fault.
    I can of course provide my account details, email address etc. to anyone BT techie that can assist and I am happy to run any further diagnostics that might me appropriate under the circumstances.
    Thanks in advance for any advice and\or furtherance anyone can make towards resolving my issue.
    Regards,
    Dizzy
    PS> if my speed increases beyond 4.5mbps I won't be upset!

    5 days into the problem and nothing much has improved. My line speed has now sync'ed into the realms of 2.5mbps so I am at least seeing circa 300kb download speeds (but that's still at least 50% less that I had).
    At the end of this post are the latest batch of diag results for anyone who wants to check them over. The only details that seem to change are the 'Cur SNR Margin' and as a result he downstream actual\attainable rate(s).
    It just simply seems that something has screwed-up the line and now I'm going throught the tedious increase period to get back to where I was. As increases always take longer that decreases it could be some time before things get back to normal (if they are on a slow increase that it!).
    The Kitz Site has some good information related to BRAS profile increases\decreases and depending on how small the increases (if any) are coming my way it could take a very long time to get back to 4.5mbps or thereabouts.
    At current rates if increases continue it could be at least 15 days (at 1/2 mbps per 5 days) making it some 20 days total to get back to where I was. All because of a fault that lasted a a fraction of a second.
    It is worth mentioning that I did have a similar long period to wait for my line sync speed to increase as a result of the water having gotten into the top of the telephone pole some time ago, which I mentioned in an earlier post, but at that time the drop wasn't too big and so a few days saw the previous performance restored.
    For the benefit of others that may read this post, I've explained in my email message to Stephanie that, I have checked with neighbours for any changes they may have made electrically, which they say they haven't, and confirmed that my modem is connected directly to the master socket, and that the master socket is an NTE5 socket so I don't need an iPlate.
    I also mentioned that I have ferrite RF chokes on the extension lines and the router<->ADSL line (supplied with the router itself) to cut RF interference that may be picked up by the system.
    On a related note, it was commented in another thread that RF chokes can cause problems with ADSL comms but that is not true (I've done a heap of research on the subject). That being said, they can actually have no effect at all if not installed correctly which is why the snap-on-cable type is best because you simply can't get it wrong.
    Anyhow, here are the stats and I hope things continue to improve, even if it does take 20 days!

  • Sudden Strange Decrease in Sync Speed

    On the afternoon of Thursday 4/3/2010 I had a strange change in my sync speed.
    For about the past year I have enjoyed a solid 3.1 meg sync and same IP Profile. Sometimes its goes up to 3.5, but never below 3 meg. I know my neighbours get around 2 meg, but working in IT I invested the time in getting decent kit and improving the connection, despite the line length being approx 4km.
    However, on thursday afternoon I noticed the PPP link was down, but the sync was still at 3.1 meg.
    So I rebooted the router (D-Link DSL-2740B)and it came back as 1.6 meg sync and 1 meg IP Profile! (Attenuation and SNR stayed the same at 63.5 and 6.5 respectively)
    Obviously I did the usual checks and unplugged everything, with the modem directly in the master socket, changed the cables, changed the filters, tried a second modem, checked line for audible noise, etc and over 24 hours got the sync back up to 1.8 meg with a 1.5 meg IP Profile, but I cannot seem to get it any faster!
    Now I know a direct neighbour (downstream) has had lots of problems with his line recently and keeping synced, but it seems odd that suddenly my connection quality has dropped by 50%.
    Could someone have done something at the Exchange (Braintree) that could have affected me so badly?
    Any help appreciated.
    Adam

    see if leaving everything alone improves the problem, its possible that someone was in the exchange and caused the problem, more likley is that someone was using a none compliantdevice in the area and caused the problem, have any of the locals recently received/used something like a shiney remote control vehicle or helicopter?
    if the problem persists then request help via the forum mods, or ring india for it

  • Increase in attainable rates and sync speed

    I've noticed that my line is now syncing at 79999 down and 20000up, lasst week, and for the past 6 months the attainable rate has been 60000 down and 15000 up,
    I'm still only getting 71000 down via the bt speedtest and 9000up, getting slightly better results on bbc though.
    Also noticed my latency to the bbc is down from 25ms to 21ms
    have there been any changes to the network or is this the DLM deciding that my line is good enough to handle higher speeds?

    I don't think your line will improve even more, as you are at the limit of your package. 
    If you look at your modem stats you will see both sync rate and max attainable rate.  The max attainable rate will only change significantly if something changes in your line.  The sync rate will change as DLM thinks fit.  If you see your max attainable rate is over around 90000, then maybe you could get more stable sync rate if BT offered a higher level Infinity package.
    DLM will always keep your sync rate below the max attainable for stability.  For reference, my values are a good but not perfect:
    Max: Upstream rate = 23773 Kbps, Downstream rate = 81184 Kbps
    Path: 0, Upstream rate = 20000 Kbps, Downstream rate = 73999 Kbps
    Down Up SNR (dB): 7.9 14.5
    Over the month or so I have been monitoring, my max attainable has dropped slightly, from just over 85000 to values around 82000.  My sync speeds have gone up a lot to reach their current appropriate value, because I had had a previous wiring issue that had lowered my DLM.

  • Slow Sync Speed

    Hi there,
    I've read many posts on this forum and believe that my sync speed is quite low. I did a theoretical max speed test for my line attenuation at Kitz.co.uk and it said that I should have a speed in excess of 19000kbps with an ip profile of 16000kbps. I have been using a dodgy micro filter that disconnected the broadband everytime I recieved a phone call however I have purchased a new one and my router is running flawlessly with no dropouts. The noise margin is constantly at 6db. I believe that this may have flagged my line to be faulty and thus resolved a slower sync speed to compensate.
    I disconnected the broadband roughly 8 days ago after it had been connected for about 15 days expecting to sync at a higher speed but infact the sync speed dropped by several hundres kbps.
    Is there any way that I can sync at a higher speed?
    Thanks in advance

    I'm guessing that I am on ADSL as it says annex A? Does that mean that I can access any higher speeds as I'm not on ADSL2/+? or would forcing the modulation on the router help?
    Update: It is set to trained mode 16 which is ADSL2+ What is going on here, I just restarted the router and it is now slower.
    Thanks

  • Loss of sync speed (over 50%), openreach say line ...

    Hi,
    I hope someone can help!
    For the last 24 months my sync speed has been a consistent and stable 7000+ so my BRAS profile was 6500.
    Last weekend the connection dropped and now will not sync any faster than ~3000, so half the usual speed, well actually less because my BRAS is now 2500
    I have checked all ADSL filters, connected the ADSL router directly to the master socket removing face place to disconnect the extension wiring, tried a different and known working router - another home hub and a Cisco, etc etc smae results.
    The SNR on the line is unchanged at 35dB as previously be good for 7000+, so I can't understand why my sync is now 3000
    At a sync of 3000 the SNR is 6dB (previously 7000 sync @ 6dB) which would suggest the line
    is noiser than before, although no additional noise is heard on the voice line.
    Openreach have been to visit - the line passed all of their tests. The openreach engineer also could not sync faster than ~3000.
    He went to the exchange and redid the wiring to the DLSAM - no speed improvement.
    He called me from the exchange and said that the DLSAM is "sending to me @ 7.2" - so I thought great, he's sorted it, then he told me no it would not be any better as "the line loses 1 meg for each km" .... so we entered a bit of dialogue about how the line could not be synced @7.x at the exchange end and 3.x at my end,  about line sync, DMT tones etc etc I think I was going over his head! He then went on about maybe it's slower because there are now more users on the exchange - again I explained about how the contention actually works on the VC to the BT core, not by BT Wholesale decreasing sync speed on the DSLAM sync... again going over his head....
    So basically he thinks it's fine as the line tested ok and I doubt I'll get any further change.
    Now here is the strange thing -
    ...it was only after the call that I realised that he'd have no visibility of the sync speed on the DSLAM so when he said it's "sending to me at 7.2" he meant that he was plugged directly into the DSLAM port with his portable tester... Now he should be syncing @ 8Meg when connected directly to the DSLAM in the exchange, so it must be a fault on the DSLAM port / profile?
    How do I go about getting BT wholesale to move me to a different port? Not only has my speed decreased but I get random re-syncs.
    Please help!!! :-)
    Cheers

    Here's the other strange thing - I just reset the line to clear the stats, and made sure no other PCs were connected, i.e no significant volume of data being send/received, and in 5 minutes I have 160,000 FEC/Interleave errors - that's not right surely?

  • How to look at Sync Speeds

    Previously on the home hub 2 and BT Total broadband you could look at your up and down sync speeds under the hub manager. Obviously now the connection comes through the openreach modem and then into the home hub. How can i access the modem page to view the sync speed ?

    You can't. It's Openreach kit and the firmware is locked.
    The only way to get a rough idea of your sync is from your IP profile which can be found by running a test at www.speedtester.bt.com.
    The IP profile is about 96.7% of your sync rate.

  • Sync speed / IP profile

    Apoloogies if this is a daft question,  or has already been asked before -  but just noticed something interesting on my Infinity 2 connection via : sync speed is 75.9 but ip profile is 73.46.  I thought ip profile controlled download speeds?  Or am I talking about completely different things.
    Many thanks.
    Solved!
    Go to Solution.

    They both control speed in different ways.
    The sync speed is the speed of the low level connection between the cabinet and the (white Openreach) modem.  That is determined by the cab and the modem, based on the rules of Digital Line Management (DLM).
    The ip profile is a limit imposed at the exchange (or somewhere near there) on the higher level (PPPoE) connection between the exchange and the (black HomeHub) router.  The idea of the IP profile is to prevent your data being sent from the exchange to the cabinet faster than the cabinet can pass it on to you.  The IP profile is automatically set from the sync speed whenever a high level connection is reestablished.  It is set to a value just below the sync speed (around 96.8%), to allow for certain overheads.  The actual download speed will be at best a little less still because of yet more overheads.
    The sync speed is automatically adjusted when the low level connection breaks, or when DLM decides to give you slightly more or less speed (usually in the middle of the night to limit disruption).  Often a break in the low level connection forces a break in the high level connection, and so the IP profile is automatically reset when the the low level sync is reestablished.  Quite often the high level connection is not broken and continues despite the new sync speed.  This results in a 'stale' IP profile.  If the new sync speed is lower, you will only get the lower speed as that is all the line can (for the time being) manage.  If the new sync speed is higher, you won't get the benefit as the IP profile will act as a throttle.  For that reason we often suggest people disconnect and reconnect the ROUTER (NOT the modem) each morning if they suspect there might be changes; to force a profile reset.  If you have an unlocked modem (as you must have) and can see the sync speed, then you can tell more exactly when a mismatch has happened and thus whether such a disconnect/reconnect is needed
    You will see from your figures that the IP profile is correctly set for the sync speed.

  • Sudden drop in transfer speed

     I have been trying out a WRT1900AC router for about a week and just developed a MAJOR drop in speed from the router to the computer while doing a file transfer:
    This thing has been sending files to and from the router's esata and USB3 port at over 50 MB/s until just now.
    I can still write to the drives attached to the router at 50MB/s + all day long. Getting files from the drives have suddenly dropped to 300Kb/s on the esata and the USB3 ports 
    Tried rebooting/powercycling the router, disconnected the drives and reconnected them, same result.
    Anyone else run into this?
    Funny, I just got done posting in another thread how fast this thing moved files to and from external storage. Now this,,,,,,
    Maybe the universe is telling me not to keep this router? 

    1. What file sizes do you usually transfer? What are the file types?
    For testing I used larger files (IE: ISO files, larger zipped files, etc.) rather than just copying folders or small files.
    2. Are the files being transferred to and from your computer and a storage drive (hooked to the WRT1900AC)?
    Files were moved all over: from a WD Mycloud (hooked up to 8 port gigabit netgear switch) to my computer. Also have a Toshiba 1TB USB3 drive plugged into the WRT1900AC USB3 port and an older WD 2 x1TB enclosure hooked into the WRT1900AC via the eSATA port. For testing I moved files all over the place: From the Esata to the computer, to the USB drive, to the WD Mycloud and back again. Also mixed up going from point A to B, then from point C to point B, etc. In all cases the slowest speed I get is 50MB/s + with some transfers topping out at 90MB/s!!!
    3. If it's a storage drive, does it have USB3 ports as well?
    Yes
    4. What is the link speed of your computer?
    Wired Gigalan 
    Routers do not usually need to be rebooted every now and then. They should be running 24/7. My guess is, the wired or wireless adapter may have adjusted speeds consequently dropping file transfer speeds.
    Agreed. I can count on one hand how many times I had to reboot my last router over the 2+ years I had it.
    Heres the other thing: the need to reboot is not just associated with file transfers. I get the "cant connect with the WRT1900AC" message just going into the user interface from time to time as well as being unable to see storage folders in Windows explorer from time to time. In these cases I can still go online, surfing and doing whatever. The router (according to the Smartlink page) just seems to disappear. Which doesnt make sense since if the router cant be seen online, how is it that I can still go online?
    Anywho, I still have this week before I lose the ability to return/exchange it at Best Buy. Will see how things go.
    And thanks for the reply and suggestions,,,,,,,,,,

  • Drop in connection speed

    early days but over the last week my speeds on the BTW speedtester has fluctuated from 15Mbps to 32 normally been steady at 38
    pages have been stubborn and refusing to load sometimes, have cleared cache--have rebootedmodem and router
    IP profile on BTW has dropped from 39 to 32
    exchange is Ealow any body else the same
    Solved!
    Go to Solution.

    the speed test as shown in previous post and others was the reason behind the reset
    This is the only reset I have carried out since installation a year ago--as recommended by the BT help pages
    I intend allowing it to settle down and see if the DLM will bring it back to normal
    my connection in the ADVANCED settings seems to renew itself every 12/13 days sometimes earlier
    coincidentally it is the first heavy rain I have had lately
    no noise on line
    hopefully they have only been working at the exchange/box
    I include the BTW info and this shows the drop in IP speed after the reset from the 38 down to 33
