Internet drops after upgrading to Moto MG8702

I bought a Motorola MG8702 because my old router was unsupported.  I have had nothing but problems staying connected.  When it works, the speeds are amazing, but it drops the connection at least once a day (both wired and wireless).  The Xfinity app says I am offline all the time, even right now, as it is working.  I used to be able to use the app to restart my modem but since upgrading it has never been able to find the new one and tells me to restart manually.  I have reset my router multiple times and I cant seem to find a fix anywhere.  Please, does anyone else have this issue with this router? Any help would be appreciated!

The problem was outside on the pole, poor connection/wires.  The tech replaced everything and set up a new connection into the house.

Thank you everyone for your help.

The Xfi app does not work with customer-owned / retail purchased equipment.

That said. What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1 or here http://192.168.0.1  


Please post the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

The stats are ok / in spec. Are there any modem component RF error log entries being shown ? If so, please post them as well in their entirety (copy and paste them, don't post a screenshot) but redact the CM MAC and the CMTS MAC addresses for your privacy. They are considered to be personal information. Personally identifying information is a violation of their forum guidelines. The forum bot will not allow your post to be seen publically.

The signal stats are o/k but the error log entries indicate that something is going on. Perhaps there is noise ingress into the line(s) /  an upstream channel-return path impairment 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 not going to escalate your issue to the Comcast corporate employees because apparently I don't even have a chance too.... Good luck !
