westell 6100 adsl sync fails among other things

I have ATT DSL pro( just the dsl no phone service) and a westell 6100 modem. Recently I have had issue with the connection. My downstream speed was between 0.2 to 0.6 Mbps so I called the ATT technician. After he fixed the issue I had my regular DSL pro speeds for 4 days and then the speeds went back to being terrible. Right now i am getting 0.5Mbps but i have seen it go down to 0.1Mbps, usually when this happens I reboot the modem and speed goes back to 0.5Mbs and its stuck there ever since.

In the connection information page, I sometimes get the following failures: Check ADSL line sync or Check ATM Signal

Currently its only the Check ADSL line syn fail error

The following is from the technician readout page of the modem:

30 Modem Health Status ok
31 DSL Link Status up
32 Time Since Last Sync 0 days 02:01:04
33 Loss of Signal true
34 Loss of Framing true
