It's also a good idea to reboot the router once a day to force the profile change.

Quote from: MickKi After three days of continuous, stable connection the BT exchange would have collected enough speed statistics (and other data) for your line. It will use these statistics to calculate what your IP Profile should be and set it at that.

Surely power cycling/rebooting the router daily to update the profile will reset the 3-5 day 'clock' used by the exchange to monitor stable connections

The ten day stablisation period is often sped up by a daily reboot.
The 3 day retrain situation will only occur when you have a significantly higher or lower resynchronisation event.
The 3 day and 10 day events are completely different.

Maybe slightly off-thread, but should I have kept my router on with daily reboots during the training period, as opposed to leaving it off but powering up once or twice a day (which is what I did)? Would this have any effect on my speed profile?

Hi, I assume you mean the PlusNet profile, which I think is derived from the BT one.
What does the BT Speed tester show as the BT IP Profile?
(Just checked and mine has dropped too, from 8000 to 7000, can't think why)

I can't use the BT Speedtester at the moment. It's BUSY... I'll try again later.
Thanks

i did manage to to do the BT tester last night at http://speedtester.bt.com/ but it didnt give the IP profile in the results, just a throughput report. also, it didnt ask for my plusnet username like is has done previously, just the telephone number. the checker is busy again today.
after the 3 day thing does the test stop giving IP profiles?
i only ask as my router has been on 5+ days and stayed synced at 7616. i know my BT profile was 7150 when i checked at the weekend, and i have been synced/connected continuously since. my Plusnet profile was 7000 at the same time. now my Plusnet IP profile is 6500.
its not really a problem but wondered:
1. how do i now check my BT IP profile if the tester no longer shows that as part of the test? or should it?
2. why would my Plusnet profile drop from 7000 to 6500 if i have got a constant, reliable connection at a higher rate?
thank you.

See here: https://portal.plus.net/support/broadband/products/faqs_and_guides/dslmax_guide.shtml#Sync
It started high and dropped, presumably as it wasn't stable at that high speed - that's what the 3/10-day period is for.
The BT Speed Tester should show you the IP profile, though in my experience it's a bit random on whether it decides to work or not, or gives irrelevant error messages - just keep trying.

Quote from: HPsauce Stable sync of 7616 would give a BT IP profile of 6500.
A stable sync speed between 7392-7967kbps will give you a BT IP profile of 6500, but only after 3 continuous and uninterrupted days. Now, if your previous sync speed was also between 7392-7967kbps then the 3 days are not going to affect your BT IP Profile as it should already be at 6500.
If you read my previous post you will see what sort of factors will affect adversely your sync speed and with it your resulting IP Profile (bad weather, electromagnetic interference, etc.) Wait until day time, sunny weather and the neighboor's electric shower is off and then re-sync. You should probably find that your new sync speed is higher. If you want to keep it that way do not resync until you have to:
Your modem will try to keep the connection going at a given sync speed unless the noise on the line is so high, that it cannot differentiate between it and the ADSL signal. When that happens the modem drops the signal and it automatically resyncs with the exchange at a lower sync speed. This is because the BT exchange equipment must make sure that the connection is stable, rather than just fast. Unfortunately, when this resync event happens the conditions that caused the resync in the first place are invariably still present (noise on the line) and therefore your new sync speed is probably no better than what your modem got. Hence my advice to not switch off your modem unless you need to - you cannot guarantee what sync speed you are going to get when you desire to switch it back on.
All of the above is unlikely to apply if the length of your telephone cable to the local BT exchange is short and the cable is new. You will invariably get a high and stable sync speed. However, when you live 3 miles from the BT exchange like I do and the telephone cables were installed in the 60's then you get what you can and you hold onto it for as long as you can.
During the 10 day period the BT exchange will try to achieve as high a sync speed on your line as possible (to the point of failure). So your final speed may settle to something lower than the maximum speeds you saw over the 10 days' stabilisation period. They are simply not sustainable when the exchange is loaded and electromagnetic noise degrades the ADSL signal. A resync during fair weather as suggested above should give you what you should expect as your sync speed to the exchange and a corresponding IP Profile from that.
Hope this helps.
