Optimal hub restart times to allow line speed to b...
Simple question, I have recently got a new hub (hh3) which when first connected, linked at 3500kb, after a 8 days there was no change in line speed, while doing some house electrical work I had to turn the power off, upon hub restart it reconnected at 10500kb..Great. Obviously getting close to the max possible line speed of my old hub (16000kb or thereabouts). I know if you keep restarting your hub the DSLAM at the exchange detects this as a line speed issue and reduces you IP profile. As the hh3 obviously cannot on the fly or dynamically adjust its link speed to the exchange eg. It requires the hub to be restarted. The question is raised, how often should you restart your hub to allow IP profile link speed increases to be detected, but at the same time no to often for the DSLAM to thinks you have a poor connection and slow you IP profile down?
Sure one of the BT tech team has the answer..i am sure there is a reconnection tolerance before IP profile reduction eg. 2x/week.
Thanks
Andrew
hi you can safely restart about 5 times in an hour without much problem some people turn there hub off each night with no problem try a restart between 8am and 1300 that should give you the best speed for a restart

I am a new Apple user and had a visitor, with an iPad, at my house. I noticed the response time slowed greatly. I have a Linksys N router and wondered if I need an Apple router to allow the speed to be consistent.

I have just renewed my 12 month home BT Total Broadband contract again (contract started Monday 14th March), and have always been very pleased with the reliability and quality of my (up to 8Mbps) actual download speed of around 4 to 5Mbps.
This time I was told I would have an (up to 20Mbps) actual download speed of around 14Mbps, which I verified using the BT Wholesale Broadband Availability Checker (ADSL2+ broadband line speed of 14Mbps, typically the line speed would range between 8Mbps and 18.5Mbps).
However, my line is now still yielding around 5Mbps, but I am aware of the 10 day, MSR, IP Profile BRAS, DLM, etc issues. The bt.com speedtester has just yielded the following Test 1 results:
Download speed achieved during the test was 5281Kbps.
For your connection, acceptable range of speeds is 2000 - 7150 Kbps.
DSL Connection Rates of 7275Kbps Downstream and 888 Kbps Upstream
IP Profile for your line is 5500 Kbps
My point is : Surely the above Test 1acceptable range of speeds of 2000 - 7150Kbps, should now be xxxx - 14000Kbps or higher, as ADSL2+ has a maximum speed of 20000Kbps and my line will support the 14000Kbps ?New upgrade ADSL2+ service started 14th March 2011.

This article from the Internet helped me to get my brain (what's left of it) round this problem. I hope it helps others too.
During the first ten days after the Broadband service has been provided, the line's performance is monitored, and the lowest connection speed is noted. This figure is used from then on to define minimum service standards below which the service can be considered to have a fault. Both during this period and afterwards, a system known as Dynamic Line Management (DLM) constantly assesses the performance of the line in order to provide information to the end user's DSL Modem/Router to allow it to choose a suitable sync rate, with which to connect to the Telephone Exchange Digital Subscriber Line Access Multiplexer (DSLAM), balancing speed against the risk of errors due to changing noise conditions. DLM can make adjustments to the DSLAM output power, suggested target signal-to-noise-ratio, and sync rate, and can choose to apply a technique known as interleaving, which aids error correction. Several factors dictate the sync rate, which limits the maximum attainable line speed, such as the presence of noise within the frequency spectrum used by ASDSL, but mainly it is the distance from the Telephone Exchange to the Subsriber, which has the largest influence on the line' performance.
Questions.
Why are my Broadband Internet speeds now slower than the old Dial-Up service ?
Why is my Download Speed now lower than my Upload Speed ?
Why have my Down / Up Noise Margins doubled overnight ?
Why is the DLM system now assessing my line as so bad, after years of quality 5000 Kbps Broadband Speed ?
Why does the achievable speed top at 7150 Kbps, when ADSL2+ works up to 20000 Kbps, 14000 Kbps on my line ? -
Strange line speed and problem.
Hey all, I am slightly frustrated as I use the internet a lot, and I do need a constant high speed, now I have seen my line test get around: 3000kbps.
However my line keeps disconnecting randomly every day, atleast twice a day, and is very frustrating, just a quick note, my computer is DMZ'd, for a public IP address, so every time it disconnects it reconnects with a different public ip address, meaning instead of restarting my computer I need to do ipconfig /release /flush /renew etc. So it is quite annoying to do all that to get my internet back.
And another annoying factor is that my next door neighbour (We are good friends) Can get ADSL2+ however when I test my line it only says ADSL1 (Using SamKnows broadband checker) which means he gets better speed.

Thanks for any help.Ring BT and regrade your broadband to ADSL2+, aka up to 20mbps. I think that will draw you into a new 12 or 18 month contract though, otherwise you will just have to wait.
I can appreciate your neighbour is on ADSL2+ but when BT Wholesale upgrade the Exchange they do lines in bulk migration, usually a frame, or part of at a time. It is possible that your line at the exchange is on a different frame to your neighbour as that is certainly the case for my mine as I am on ADSL2+ but my friend next door is still on ADSL Max. -
Home hub 3 orange power light and speed problem
Hi, I have posted this again as I think I posted in the wrong place last time being new to the site!
Hi, I have a Home Hub 3 Version A. Orange power light constantly on.
I came across this site while looking for answers and quickly registered to post this.
I have tried all suggestions including a neighbours power supply (Version A as well) to no avail.
Background to help with replies.
I have been had option 3 since 2003.
In that time I have had
H H 1 (failed)
H H 1 replacement (failed)
Netgear – weak wireless and does not like Vodafone suresignal
H H 2 constant dropouts
Back to Netgear
H H 3 Version A lasted 24hrs
Back to Netgear.
For the last 5 months we have been having line problems, regular dropouts.
BT Openreach have been out 4 times, changed virtually everything and traced line back to Exchange.
The last engineers conclusion was line at my home is capable of 12meg and was being throttled as he called it to around 6meg.
He suggested trying a H H 3 and contacting BT for line to be opened up.
For two reasons.
With a faster speed line fault would be easier to locate.
Line was capable of so much more.
Several LONG calls to BT answering all the format questions first, (to be fair 0800 so no cost) each time first being told my speed was within contract stated speeds, then after my explanation regarding BT Openreach engineers views I was told an engineer would be contacted to improve line speed.
Needless to say nothing happened.
The frustrating point being each new call generated the same response – NOTHING on their system to show a previous call had been made by me.
Hence the reason for this post.
I feel the helpline, whilst free, achieves nothing except a long time on the phone answering repetitive questions answered before.
I am loathe to phone again as I will undoubtedly be told there is no record of any previous calls or action and I want to resolve the H H 3 Version A problem so it can be used.
Any help appreciatedHi John46 and thanks for the reply.
Can't try H H 3 it is dead.
i saw somewhere on the forums when i first found you about a route that simplifies action from BT.
Have looked since and cannot locate it.
Do you know where it is?

Thank you for pointing me to the test, even if I had a game with Java before I could use it (New PC)!
As I read the results I am under 8meg. Openreach engineer said line was being 'throttled' as it was capable of circa 12meg this distance from the exchange. I am meant to be on 20meg contract.
Chhers,
I will watch out for a reply.
Any pointers on the H H 3 complaint route would be appreciated, i am begining to think I imagined it!!!
ps Where is the rating star? I can't see it here ? -
I have been checking my line speed since June 1st. It varies from a pathetic 104Kb/s to a not particularly good 728Kb/s. It is about 720Kb/s for periods as long as 5 days or so but slips back to 480Kb/s and is not about 136Kb/s.
My Option is 2 and I pay the same as users who get 20Mb/s. I would be very happy if I could get a reliable 1Mb/s so I could watch YouTube without having to go and make coffee all the time. On one occasion the speed measured a dazzling 984Kb/s. If this figure is real why is it that the usual speed is so poor and variable?
The Hub Manager claims a Download Speed of 736Kb/s and Upload of 448Kb/s which is totally inconsitant with Broadbandspeedchecker.co.uk which normally shows a faster Upload speed than Download.
I viewed BT's own You Tube clip about 'Home Wiring' which is 2:04 mins long. It took 11 minutes to download!
I have exhausted all the normal home wiring checks etc. What do I do now? Try and post your linestats .... and a BT speedtest.
Loads of help to be had .... -
Line speed cut from 2meg to 256kbps
Last week my line speed went from a slow, but at lease usable 1.5/2megs, down to a completely unusable 256k. I can't download, can't even play online with that.
To say I'm miffed is an understatement. Is this a known problem, and is it temporary?
Anyone else having this problem.
Connected to the Ranmoor, Sheffield exchange if that helps.Hi, here are the BT wholesale line stats:
"For Telephone Number 0114xxxxxxx on Exchange RANMOOR
Your exchange is ADSL enabled, and our initial test on your line indicates that it is VERY UNLIKELY you will be able to receive fixed 512Kbps or 256Kbps broadband service due to the very long length of your telephone line. However, your order will be accepted if you still wish to order. An engineer may need to visit who will, where possible, supply the broadband service.
Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 250Kbps.
Your exchange is planned to have ADSL2+ by 31st January 2011. Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 500Kbps.
The actual stable line speed supportable will be determined during the first 10 days of use. This speed may change over time, to ensure line stability is maintained."
I'm (rather gallingly) on Option 3 because up until now, I've needed an unlimited service (although at 256k, downloading anything isn't really an option), so it looks like it's definately a problem with the line, rather than the hub, but what could have changed? -
Line speed at 4.3 MBPS speed test at 100 KBPS
The following is an account of what lead up to the problem I currently in a hope this presents a clear fix to the problem.
On Tuesday the 17th of September the landline telephone stopped working and the speed of the Internet dropped form the normal speed test of 2MBPS to around 100kps (variable but not by much). After doing basic tests on the network and phones and because of the present problem with the phone as well as the Internet (although why it remained up just very slow is unknown to me) I thought it must be a problem that openreach had to deal with
narually an openreach engineer was phoned and he arrived on Friday 21st and tested the line; no fault was found in the phone line (this had mysteriously fixed it self) and the speed tested at the line was 4.3 MBPS this was higher then i normally receive so it surprised me after I did a speed test speed remained at 100KBPS. Since there was no fault on the line (currently) the openreach engineer went home. and i began touble shooting the network.
Network lay out
line > bt home hub (modem > switch) > business firewall > switch1(connected to PC1)> swtich2(connected to PC2,PC3,PC4,network drive)
after checking the whole network the fault was at the modem, after testing the modems internal switch there is no loss of speed at the modems switch.
Modem clams line speed is 4MBPS
speed test 100KBPS
the hub maybe at fault i have already reset many times

Verizon.net Email Speeds Do Not Match FIOS Line Speeds
In the past months since about September 2012, Verizon email servers are not moving data as fast as the line speeds customers are subscribing to. Such as, Fios 15/5 mbps line speed package, using a browser and going to a speed test website, the results are equal to or better than 15/5.
Except for when Verizon.net customers use the Verizon.net email accounts which come with the internet package. Those speeds have degraded, especially when moving from the old email servers to the new ones (incoming.verizon.net to pop3.verizon.net). The overall speed with their email, via browser or software (Outlook, Windows Live Mail, Outlook Express, Thunderbird etc.) has dropped to as little as 1.0 mbps when obtaining email, especially those which have some payload such as a 6 MB .pdf, .jpg., .tiff, .zip, .rar and so forth.
What's fowl about this is, Verizon.net support folks have no access to the email network so they are unable to communicate to those running the email servers that customers are unhappy with the service. Mostly, those who are new to Verizon Fios just continue to use their Gmail or Live accounts which just happen to work satisfactorily, speeds in the area of the above example, 15/5 mbps.
What's really bad about this is, upgrade to the Quantum Fios packages and guess what? Email speeds don’t move an inch faster. This means, the email network/servers with Verizon.net are speed regulated outside of the customers line speed connection. Too bad, customers pay extra for more speed yet, email with Verizon remains at the slow pace. I have much issue with this since in the past, this had never been an issue. Now that Verizon has Fiber, it is? It would be nice if they published this alongside of the many features that come with a Fios ISP account however, it is nowhere to be seen.
This is obviously bait and switch service and features.You don't go into the details as to why the account was suspended ... that background might be helpful since you're asking others for their opinion. In general it sounds like the account was "deleted" at which point all mail is bounced because the address no longer exists -- but Verizon holds the name in reserve for some period of time to prevent someone from re-registering it in case an error was made and for some level of security, I suppose.
Anyhow ... on your commentary about not using an @verizon.net address as your primary address ... I think you will have this with many providers. Hotmail, Yahoo, and Gmail all do this if you terminate the account (they do have a suspended account due to inactivity feature which operates differently, but pretty much do the same thing for deletions and such. I don't use the @verizon.net account as my primary for a different reason however -- my primary address is provider agnostic. I can move providers (although I'm quite happy with FiOS at the moment) -or- if at some point down the road I have to move out of Verizon territory, my email address will not need to change. I used this little fact to my advantage when I moved from Comcast to Verizon a few years ago -- no one knew I changed providers because my email address didn't change. Now .. I don't use one of the free services for email, I own my own domain name (about $10/year from the likes of GoDaddy) and have my domain hosted on the Google Apps tier (but even without that, GoDaddy will do basic forwarding for you of any email address to whatever mail account you're presently using). Something to think about. -
Why do I have to keep restarting my hub several times a day?
When I go to print something over wi fi it prints out a page but then doesn't print when I go to print something else without having to restart the hub again. I also have a message there is no connection on my ipad or iphone when all 4 lights are on and the only solution is to once again restart the hub. It gets so frustrating!!!as it is the old HH2 then this may be your problem http://forumhelp.dyndns.info/hardware/hh2/hh2_issues.html
you should complain to CS and ask for new hub which will be free if you are still in 12 month contract with BT

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!

BB line speed is now half the speed since moving t...
I would like to know why the line speed is now 0.77MB when it was more than 1.7MB when I started with BT.
We used to be able to watch films on ipad without problems but now this is not possible unless you want ro watch it minimised which is not acceptable.
I can't understand why BT thinks a line speed of 0.77MB is categorised as "good". This is NOT good.
Please help!welcome to the BT community forum where customers help customers and only BT employees are the forum mods
in order for the forum members to help please can you post the adsl stats from your router may need to 'show detail' to get all stats (if hub enter 192.168.1.254 in your browser and navigate to adsl or use a-z, if netgear enter 192.168.0.1) and run btspeedtester (MAC users may have problems). when first test completes then run diagnostic test and post the results .
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

I'm sorry but that is rubbish. There is no way that your speed has been cut on purpose mor likely there is a problem with your connection.

For 3 days now the line speed has been very slow, today it is 0.974 - not quite the 6mb promised. The BT online speed checker will not complete its check as 'the line may be slow' !! I've done all the checks I can and nothing has changed here, the BT site says that all is well in my area and my computer is not slow.
Any ideas as to the next step?welcome to the BT community forum where customers help customers and only BT employees are the forum mods

Line speed now down to 288Kbps on ADSL, can anyone...
Hi there everyone, my line speed on ADSL has gone from 2MBps at the start of April, to 576KBps sometime after the 6th, and finally 288KBps on the 21st. My Speedtouch ADSL modem reports line OK, and the landline is fine. Where can I get this checked? Nothing has changed inside the house. Is there any bandwidth capping going on here - since I don't really want to pay £15pm for a 288K service - 2MB was fair enough. Regards Mike Bell
Solved!
Go to Solution.Hi there Keith, speedtest results as follows.
1. Best Effort Test: -provides background information.
Download Speed
0.23 Mbps
0 Mbps
0.25 Mbps
Max Achievable Speed
Download speedachieved during the test was - 0.23 Mbps
For your connection, the acceptable range of speeds is 0.1 Mbps-0.25 Mbps.
IP Profile for your line is - 0.25 Mbps
2. Upstream Test: -provides background information.
Upload Speed
0.58 Mbps
0 Mbps
0.83 Mbps
Max Achievable Speed
Upload speed achieved during the test was - 0.58Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.83 Mbps
We were unable to identify any performance problem with your service at this time.
It is possible that any problem you are currently, or had previously experienced may have been caused by traffic congestion on the Internet or by the server you were accessing responding slowly.
If you continue to encounter a problem with a specific server, please contact the administrator of that server in the first instance.
We have identified that you have additional services enabled on you broadband line, please click continue to run advanced service tests.
It seems perfectly happy and stable - but what is this IP Profile DL of 0.25Mbps? What next? I tried the quite line test and the phone line is silent.
Regards
Mike Bell
