Problem is with connection speed and maintaining a connection. Speed will go from 54Mbps all the way down to 1Mbps and will then work its way back up or will just bounce from 54 to 48 to 36 down to 24. At 24 Mbps it is pretty much useless. I can have days with relatively few problems and on others it will be nothing but problems.
I have had no less than 10 AT&T techs out here and at least 2 AT&T linemen. So far I've had 3 modems replaced and (supposedly) been placed on 2 different ports on the VRAD. I've been told that I have been put on a different conditioned pair on one occasion.
The folks who come here tell me everything looks good but some of the level 2 techs that I've spoken to have told me that they see line issues.
My RG is a 2-wire 3801 plugged into a UPS. The wiring is all cat 5.
