Constant Disconnect and Reconnect

My U-Verse service started to lose service yesterday afternoon (12/23/2014).

Service: 12 Mbps/1 Mbps; No phone
Modem: Motorola NVG510

Issue:
The modem constantly reconnects i.e. broadband light flashes green -> solid then service light flashes green -> solid. After 10 to 20 seconds, the connection drops.

I took a look at SNR and Attenuation when the modem successfully connects, and right before the connection drops.

Successful:
Downstream Upstream
SN Margin (dB) 6.1 11.9
Line Attenuation (dB) 27.0 14.1
Output Power (dBm) 19.3 11.9
Errored Seconds 0 0
Loss of Signal 0 0
Loss of Frame 0 0
FEC Errors 0 0
CRC Errors 0 0

Right before the connection drops
Downstream Upstream
SN Margin (dB) 6.4 14.7
Line Attenuation (dB) 27.0 14.1
Output Power (dBm) 19.2 11.9
Errored Seconds 11 0
Loss of Signal 0 0
Loss of Frame 0 0
FEC Errors 0 0
CRC Errors 677 0

Last time this occurred was during the summer ~ August. A tech came out and did not resolve the issue. He redid some wiring and said to wait a day for the internet to come back.

Is it raining, or been raining....
Issue is CRC , errored seconds, a line problem, inside or outside....

Request a tech visit is about all you can do if believe issue is not inside home, such as animal playing with data cable (chewed).

It hasn't rained since last week.

Oddly, the connection is stable now since it has started to rain.

I have requested a tech to come and the earliest available was the 26th.

Current Stats:
Downstream Upstream
SN Margin (dB) 10.3 14.4
Line Attenuation (dB) 27.0 14.3
Output Power(dBm) 19.1 12.1
Errored Seconds 17 0
Loss of Signal 0 0
Loss of Frame 0 0
FEC Errors 0 0
CRC Errors 17 0
