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.
