It was a bit stable earlier, it was up for about 5 hours, but now it keeps cutting out about every 2 minutes
said by coryw:The link time is in the section right above DSL power.
I would also look at Utilities (at the top) and Modem Log (on the left) which might give you a reason for re-trains since reboot, if that's what's happening.
The logs for what the modem interprets as a physical disconnect from the Internet, either due to extremely low SNR or a cable being unplugged, are as such:

06/07/2014 09:56:21 AM DSL WAN Physical Link Up. Upstream 672 kbps Downstream 1536 kbps, DSL Type is ADSL_G.dmt

Unfortunately it doesn't actually tell you which it thinks it was, or log the stats at the time of the disconnect or the retrain. (which would be neat and hopefully useful.)
Your SNR and other power stats look good, so it would honestly surprise me if there was a noise/signal related disconnect going on, unless it's only happening during the day, on weekdays, and what's actually happening is maintenance/buildout is happening to the lines up stream from you.
