I haven't been able to put my finger on it, but there is obviously something wrong with either my XB7 and/or the coax wire/splitter somewhere. The coax is a direct run from the cable junction box right to the wall jack.
If it`s a direct run, where is this splitter you mentioned? Any Junction in the COAX can cause a problem, even if it`s a female coupler joining the lines, or wall mount, can be a problem.

What stats can I post here from the modem that would help to diagnose a potential signal issue?
What do the modem's signal stats look like ? Try getting them here http://192.168.100.1 or here http://10.0.0.1
Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

The coax comes off of the Comcast installed splitter directly to a wall mount jack, then into the modem.
Here are the stats from the modem:

FWIW, the stats (if they are remaining stable) don't indicate a signal issue / excessive line attenuation.
