The Plusnet guide says that frequent disconnections can lower your speed profile because it thinks your line is unstable which I understand but it also says ‘speed reductions are never permanent but can take up to 3 days for your normal speed to return to normal’ Is this true, or do you have to request a SNR reset? Do linespeeds recover by themselves?
I’m sure I also read if your profile gets stuck on a slow speed then you can to disconnect and reconnect once a day for 5 days. Again is this true?
And one final thing – where should I be checking to ensure I’m not losing speed. I currently check the upstream and downstrean figures in my router settings, and do a check on speedtest.net.

Providing you click on disconnect from the router interface and after a couple of minutes disconnect the router from the socket it shouldn't cause problems

Quote from: jelv Also multiple disconnections more than an hour apart shouldn't cause problems.
Ok cheers, I did do 2 within the hour so will have to see. As for using the Disconnection in the router settings, I take it when you connect the router back up, it connects again automatically, or do you have to go in here and select Reconnect?

Quote from: scoobydoo1 why would it shorten the life
short answer: thermal cycling and inrush currents.
It's noticeable with filament light bulbs - the filament slowly degrades, getting thinner, but the operating current is lower than the start up current, so they almost invariably "blow" when switched on
Using a TP-Link Archer VR600 modem-router.

What about these 2 points?

It's a lie that it can take 3 days for the IP Profile to reset to match your current sync speed - it can take up to 5 days depending on how different the speeds are (a small difference takes longer to correct than a big difference).
Target noise margin can take weeks to correct and will typically come down 3db at a time. If the target has been set high for some reason and that issue is resolved and the line is stable a SNR reset is appropriate.
* On 21CN the IP Profile is always set immediately upon connection to 88.2% of your sync speed.
