Yeah dropped you an email last night. Left it off for a good while changed routers again and all started working again.
Not got much confidence in this line get these weird problems every so often usually around Christmas time has happened on/off the past 2 years, random losses of sync, no traffic stuff like that.
Previous ISP got BTW out who promptly tested it and declared it working (hello intermittant fault you jack asses which is what it was reported as fgs) and have given up since it works 99.9% of the time and lifes too short lol.
Sounds like you've got a similar line to mine Rich.
AAISP hammered BT into doing something about a year or so back and got my card changed at the exchange (which is great, seems like I'm the only one on it for a whole year! LOL
) and my line swapped over. All was fine for a while but the disconnects started happening again a few months back along with my phone not ringing...... BT still cannot find the fault on the line and work out why the phone intermittently does not ring (screen lights up with incoming call?!?!) and I even wasted £80 on changing my phone system too!
2011 now and 100+ years later the Third World country we live in is still operating on two copper wires for telecoms, you couldn't make it up!
