In reply to a post by number45:

But shouldn't you keep the router on to avoid speed drops due to regular disconnect/reconnect though. Which I assume will happen during the night when things are switched off.

If it's off there's nothing to "disconnect/reconnect"!

Switching it off and on will cause disconnects/reconnects.

Swicth it off at night will cause it to disconnect, switching back on in the morning a reconnect. I thought doing that regularily could cause lower speeds as the connection was seen to be unstable.

Connect on demand can do two things

1. Only sync on demand - very rare
2. Carry out the authentication - the most common

And (2) will avoid drops looking like disconnects

The concept of connect on demand is out of date, but generally still exists due to coders carrying on from ISDN type days, and a few places around the world that charge for the number of minutes you are authenticated

we were told in the past to switch off, but not to unplug the lead to the phone socket first. Pulling out the lead shows as a disconnect, but if you power off the router, apparently it sends a "last gasp" signal and the exchange equipment wont register it as a disconnect.

I see.

Thanks for explaining.
