Disconnects and issues with phone service on Uverse over the past few days.

Over the past few days, I've had several outages with my Uverse. It'll come on for 2-3 minutes, then go off for 10-15. Then randomly stabilize for the half the day, only to start up again for several more hours. I'm assuming it has something to do with my SN margin. 

This was taken just now. When its operating normally my Down/Up SN margin stays around the 14-16 range. But ever since these disconnects began, it's dropping to 5.5ish average, falling to 0 when it goes out. Sometimes 'Down' will hit 1-2 and 'Up' will jump to 100. 

Here is a section from my logs.

It's also creating a problem with regular phone use. The person on the other end can hear me fine, but I can only hear about 1 out of every 3 words from their end. 

I have disabled IPv6, no change. Tried a separate cord from my modem to the wall, no change. Saw no external damage to the line around my house. The only other thing I can think of is that a few days before these issues began, I had trouble accessing an educational site. DNS errors. So I swapped over to the google public DNS and that fixed it. I've swapped back since then, no change. Though things do seem a bit more stabilized when I have it set to the google DNS. Not drastically improved, it just feels like it disconnects less. 

*Edit - Forgot to include my modem. Motorola NVG510.
