First thing I've noticed is that if I set my Netgear modem to ADSL2+ it actually syncs at a lower speed and the connection can sometimes be very unstable.
The only way for a more stable connection is to set the modem to G.MDT, stat is this mode are:
Connection Speed 7328 Kbps 832 Kbps
Line Attenuation 39.5 dB 21.5 dB
Noise Margin 4.8 dB 7.0 dB
But I've get intermittent problems in that the connection sometimes just pauses, nothing seems to happen to sync speed when this happens, it's difficult to explain but I just get a consistent internet which pauses/hangs for a few seconds then returns to normal.
Things I've tried so far are changing the MTU size, the Netgear modem defaults to 1458 but I set it to 1432 and that made the internet completely un-usable, I've tried 1400, 1492 and currently have it set to 1500.
Looking on the internet, 1432 is suggested but it looks like that was before exchange LLU, my exchange has been LLU'ed (is that the term ) and the suggestions for this 1500.
I can 't really talk to TT as their suggestion always seems to be to drop the line speed which they've have done in the past, down all the way to 3mb but that didn't help.
So the question is, is the above just normal TT service, was with BT before and the internet connection was rock solid.
