Lost 20mb in sync speed after repair.

Hello, in mid December my infinity connection stopped working, took 10 days but eventually got an engineer out. He replaced the landline faceplate and the openreach box, which fixed things. He also said he reset the ip profile on my line as I'd been without a connection for so long. He said it'd take a while for it to get back to normal speed.
Well it's been nearly two months and the speed has remained where it was since the connection was fixed. I used to sync around 75mb, now it's around 54mb. Not a big deal most of the time, but losing over 1mb in download speed is noticeable when streaming or downloading games from steam. It's also worth noting that my upload speed appears to have gone up.
I'm presuming this is an ip profile issue, although it could be the new hardware. Is there anything I can do to try and get my ip profile increased back to where it was so I can get 75mb sync again?

I am of course using ethernet. I've had fibre for over 2 years. For about 3 months I was on 25-30mb, then got a free upgrade, where upon it was steady at 74mb for a good 21months, would get the occassional disconnect but it was pretty solid for the most part. And as I said when it broke in december I was without internet for 10 days, engineer replaced faceplate and openreach box and said he reset my ip profile. Used to be 74mb (about 7.5mb/s max download speed) now it's 54mb (about 6.4mb/s max download speed)

The server lost all my sync data after new OS install (I know my pass & key); How do I get it back?

Hello,
Ive been using sync on both my laptop and desktop in windows 7 and linux mint. Its been working great cross platform, but I recently formatted my drives and reinstalled everything. I obviously didn't save the Firefox passwords because I trusted the sync server to have it all. After a fresh OS install, I installed the latest ver of Firefox, logged in to my sync account and selected the default option for sync (both ways) knowing that the server has all my data and will download it onto my newly installed Firefox.
Unfortunately the server doesn't seem to have my data anymore as it didn't download any passwords I had saved and sync since before the full format/installation process.
How do I get it back now? Does the server has a roll back function?
Thank you
Ovi

Thank you again for your kind and prompt reply. I really appreciate it. I think the fact that I am transferring stuff from my old desktop PC to a new laptop has saved me. I copied all the apps from iTunes on the old desktop to a flashdrive, then added those apps (via Explorer!) into iTunes Media. Then I synched the phone. I have got all but 45 apps back, including the data!!! How awesome is that! It's 9.50 pm here in Australia and I have been sat in front of all this technology for about 15 hours now, so I'm giving up for the night. Perhaps tomorrow, somehow the lost 45 apps will magically appear. I haven't quite worked out which ones I'm missing as I'm so tired.
I want to thank you most sincerely though for taking the time to reply to me. You are wonderful.
Please, Heavenly Technology God, let this all work in the morning.

URGENT: I lost the Lion Partition after repairing the Windows 7 partition

URGENT: I lost the Lion Partition after repairing the Windows 7 partition
I have recent bought a new Macbook Pro and then I start doing all the necessary setup. This is the first time I do such setup with bootcamp myself anyway.
1st: normal MacOS setup, the Lion version has been setup perfectly.
2nd: run the bootcamp and setup the Windows 7, done perfectly as well.
3rd: try to partition and resize the harddrive with the Lion installed and create 2 new FAT partitions (now 4 partitions in total: 1 for Lion, Journaled, 1 for Windows 7 in NTFS, 2 for file sharing purposes in FAT). See if I can have better partitioning to do necessary organisations.
4th: When I want to restart in Windows to see if the newly created 2 FAT partitions can be read in Windows environment and can function norally, the Windows setup does not show at the start up page when I hold the "Option" key during the startup. I then try to restart again, still no such partition but boot directly to Lion.
5th: I tried to repair the Windows 7 with the start up disc and then it worked. I can also see the 2 newly partitioned FAT drive work normally.
6th: When I want to restart in Lion, I cannot boot the Lion OS and I cannot find the start up icon on the startup page even with me holding the "Option" Key.
7th: "MacOS Installation Utility" appears. I tried to repair but cannot as I have neither the Lion setup disc with me (coz the Lion has been pre-installed) nor a time machine backup/ any other backup image to load from.
8th: Tried to "erase and install a new copy of Lion", the partition where the Lion has been previously installed cannot be shown, now indicate itself as "freespace" and not able to be selected for my "erase and reinstall" process.
9th: so I go to 2 other FAT drives to do as the instructions to try "erase" and hope the "reinstall" process can be started. But the Disk Utility ends up saying the drive cannot be dismounted/ cannot verfy...
At the end of the many tries, I tried to shut the computer down and restart again, hopefully something will work still.... the startup page now shows a disk image with ?, I guess NO OPERATION system/ drive detected for booting. So I got a piece of metals without any use now...
Anybody help? Thanks alot!!

I accidentally deleted an Application on my iphone 5 and with it lost important files. How do i get back these files. The last iphone backup sync was after this so I cant even access an older back up as I cannot find them. How do I get back my Lost files.

On your iMac launch iTunes and at the top next to the Apple symbol click iTunes > Preferences > Devices and tell me what you see. You last sync should be there showing only a device name. If you have an older backup it will be there as well the difference is it will be the device name with a date and time stamp. Sync and backups are two different things and there is a chance iTunes made a backup the first time you hooked up your iPhone 5.

I have music loaded from cd's. They were intact after each sync. After a iTune upgrade, I lost all the music at sync. Can I restore them from old backup in iCloud ?

Unless you'd signed up to iTunes Match then they won't be in the Cloud, only music purchased from iTunes (if you are in a country where music can be re-downloaded) will be there. Have you not still got it on your computer and/or on a backup which you can use to sync it back to the iPad ?

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.

I have lost some of my bookshelfs after the last update!

I have lost some of my bookshelfs after the last update and cannot create a new one. How can I fix it? I don't have them on my PC so I can't synchronize them. What can I do? Pretty dissapointed right now!

If the contact were added after the backup was made they will not be in the backup. If your contacts were synced with iCloud they may be there. If so they will apear shortly on your new phone.

Can anyone help me with iPod/iTunes syncing problems after recent software update?

Hi there,
I wonder if anyone can help me. Last week I updated my iPod to the latest software (8.2). Today I deleted some albums from iTunes and added a few others. I also made some changes to a few of my playlists. I then synched iTunes and my iPod. However the synching has not worked.
When I connect my iPod, it shows up in iTunes pretty instantly. When I click on sync, I can see in iTunes that it is syncing and also on my iPod, but the changes do not appear on my iPod afterwards. Also, after the first syncing attempt, I lost two-thirds of my album cover art. So, I lost covert art, but no other changes were made. The albums I deleted from iTunes are still on my iPod and the ones I added to iTunes are not on my iPod.
I have looked at the music on my iPod while connected to iTunes. I can see the songs/albums I have added are there, but they appear in grey and have a doted circle (to the left) next to them. This shows that they have not synched (I guess).
I have already restarted my McBook Pro and iPod a few times. I synched my iPod with iTunes after every restart, but it has not made any difference. I also deleted the music I added to iTunes and added it again. I synched iTunes and my iPod after this, but it has made no difference.
I would appreciate any suggestions.
Many thanks
Summary:
Updated iPod to iOS 8.2.
Made changes in iTunes i.e. delete and added music
iTunes and iPod show they are synching, but changes to not appear on iPod.
Also lost cover art on iPod after synching.
Products:
iPod Touch, latest generation
iTunes 12.1.0.50
MackBok Pro OS X Mavericks (10.9)

Thank you for your reply. I followed your suggestion and restored my iPod to its factory settings. I then restored it from a backup file. All the problems have been resolved. Quite incredible that I had to go through that process to fix it. I hope Apple will find a solution to the iTunes problem soon.

Internet still the same speed after 3 days

Hello
I have read on the forum that it can take upto 10 days for the IP profile to raise in line with the sync speed of my new broadband connection. The documentation that comes with the router though says that after three days i should see an increase. From day 1 the router was connected for 3 days 18 hours but i had to move the router a day ago so not a continuous connection unfortunately! BB has been active since last Tuesday. Here are the router stats.

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
Matt
PS provider is BT Total Broadband

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?

Slow broadband speed after exchange upgrade

Hi,
I wonder if anyone can help. My local exchange was 'upgraded' on 14th August, immediately following that my Broadband speed has halved and never recovered, I used to get approx 7Mbps connection speed with a 5.8 ~ 6.3 Mbps down load speed. SInce then and upto now I only get a connection speed of approx 3.3Mbps with a download speed of around 2.8Mbps.
Since we have BT Vision this is now close to the limit of what it requires to work for on demand content.
I have spoken to BT Technical on a number of occasions. At first they told me it was my router (HomeHub V1) and that I could have a new one if a signed up for another 12 months. Since I doubted this and I also had a Home Hub V1.5 router I swapped to this router and it gave the same results! This was on the 7th September.
Since then I have spoken to BT Technical on a number of occasions, always this involves the same path - get asked whether I have tried different microfilter, connection to the main socket blah blah. Then they check the exchange, it comes up with a CC12 ADQ error, they ask BT Wholesale to investigate, BT Wholesale clear the error, BT technical ring back, ask me if speed is any better, tell them no, they say they will reset the line profile, this makes no difference!
If I ring again then we just go round in the same circle again.
Has anyone got any ideas or can someone sort this out, fed up of pointless phone calls at the moment!
Here are the line statistics from the BT Home Hub (V1.5) as things currently stand.:
Hope someone can help,
Thanks

Well 12 days later and still no improvement. Changed back to the homehub V1.0 (10 days ago) as the Homehub V1.5 was to unstable and kept dropping connection every few hours.
Spoke to BT technical last Sunday, they agreed to send me a new HomeHub in the end. This has now been lost / stolen during delivery - what a farce. Spoke to BT Technical again last night, went through the same sets of testing same results. Technical this time said I shouldn't have been sent a new homehub anyway as I was not in contract!
Reading through this forum and others it seems that there are a lot of people reporting speed issues (speed halving from original sync/download speed) when exchange has been upgraded to ADSL 2+ and the home hub is V1.0 or V1.5.
The tech i spoke to last night seemed to think it was the homehub but said i wouldn't get another one unless I signed a new contract. Told him there was no way I would sign a new contract when their customer service was so poor and they are unable to resolve problems.
He stated he would reset the I.P. profile. This morning download SNR has shot up to 30db (has got down to 18db) last night and sync speed was lower.
It seems to me that BT know there is an issue with HH V1.0 and V1.5 and ADSL 2+ but rather than send you a new router ask that you sign up to a new contract. This seems partly a ruse just to tie people into another 12 month contract.
My neighbours have the same set up and are experiencing the same problems since the exchange upgrade!

HT4859 I have lost all my iphone contacts after I sign in to iCloud, how can I retrieve again my contacts?

I have lost all my iphone contacts after I sign in to iCloud, how can I retrieve again my contacts?

This has happened to me too!
I have lost all text messages, photos, notes and calendar dates. Also some of the apps.
I think it was my second time of syncing. Also I tunes keeps opening when no apple prod is connected, and a dialogue box tells me it cannot find the I phone. When it is not connected?..
Any news would be good news

Lost 20mb in sync speed after repair.
