Looks okay to me but the SNR seems a bit lower. Not out of spec tho. That could be fluctuating down lower.

What issues are you having specifically? Also it might be a good idea to call comcast and ask them what you Upstream SNR is.

Does your modem log show anything as regrades to T3 or T4 timeouts?

How many time outs of those is there? Did you call comcast and ask what your Upstream SNR is?

FWIW, may I add that sometimes a low SNR with a forward (downstream) power level that is strong can indicate a failing modem.
