Hey guys, I did call BT few weeks back about this, no help!
I have realised in the past 4-5 months, the connection keeps dropping way too often. A new IP is then received, it's like the lease is very short, sometimes it'll do it 2-3 times a day at random times! It does come back up within a minute or two and I know it's not the Draytek, seeing the forum, it seems few others have got it!
I use a DrayTek 2862 router not the BT one, it has worked fine for over 2 years now, just the last few months have been very annoying!
I am on the 3.9.2_BT on the Draytek which was the latest, but I did the upgrade to this version after this issue begun.
check for line noise dial 17070 option 2 should be silent and best with corded phone preferably from test socket
Sorry, should have stated, I have done the noise tests from the master socket, all good on that end.
I do not have the old BT Smart Hub any longer, so can't test it with that, but doesn't explain why so many disconnects and only in the last few months.
your ip address is dynamic so it basically changes everytime your router drops connection and restarts nothing to do with lease time
does router drop connection about same time or just random?
have you tried using test socket with filter to eliminate problems with master faceplate and internal wiring?
Dynamic IP's are leased out for however a short time, it's not true that with every reboot you'll get a new IP. Certainly was not the case 6 months ago when I did restart the router often as I was testing the WiFi and making other changes not related to the WAN connection, the IP would normally remain the same, frankly speaking, not bothered about the IP change, more concerned for the connection dropping, especially in the last 4 months perhaps.
I was thinking maybe BT are doing some work at my local exchange, but they told me none is happening and they cannot find any issues on my line.
Maybe someone else here has experienced this issue, the settings on the router are the same as before any of this begun to happen.
