internet drops every 70 minutes (XB7)
This started yesterday morning (7/28)
San Jose, Ca area
we drop internet about every 70 minutes for about a minute or 2. I started watching the XB7 and noticed it goes from solid white to a solid orange and then blinking orange as if it lost connection.
Thoughts?

Those router component event log entries are unhelpful, unfortunately...
They disabled the modem component's RF error logging feature (the important ones) in the Comcast supplied gateway devices.... A BIG mistake IMNSHO !!!!
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.
What is the exact make and model number of the modem ?

Even though the signal stats looked o/k at that snapshot in time, there must be something intermittent going on. Perhaps there is noise ingress into the line(s) somewhere.
There are other signal stat figures that can't be read by the modem. They are the "Upstream Rx Power" (Upstream Receive Power Level), the "Upstream SNR Ch." (Upstream Signal To Noise Ratio), and the "Upstream ICFR" (In Channel Frequency Response). These are as equally important in diagnosing connectivity issues as are the modem's stats.
I'm going to escalate your issue to the Comcast corporate employees that are available to these boards. They can check the CMTS (Cable Modem Termination System) for any real time degradation and / or error reports, see your node / cable plant and modem health, and see whether or not everything is in the green zone. They can also see a history plot for the modem and poll for those upstream receive signal stats.
You should get a reply here in your topic. Good luck !

Wanted to make sure these were tied together, since the symptom is identical
