westell 6100 adsl sync fails among other things

Hi,
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
35 ATM Cell Delineation true
36 Internet Status up
37 Ethernet Link Status up
38 PPP Connection Status connected
39 PPP Last Connection Error None
40 PPP Uptime 0 days 02:01:04

the following is the rx tx stats; also from the technician readout page:

and the following is the line stats:
