High Upstream Issue - Motorola MT7711
Hello,
I have been having connection issues since I've purchased my own modem. My connection is stable for a couple of weeks then suddenly it's cutting in and out for a day or so.
My solution is to reset the device, reactivate the service until I get a signal. IAs my temporary solution, if resetting doesn't work during my work hours then I log into a myxfinity hotspot. This is a frustrating situation since I am working from home.
I've checked with the Motorola technical support services. Shared bunch detailed modem information and logs to identify what the problem is. Eventually I've been told that my issue with my internet connection was related to the high upstream power being sent to my device. The best range for the upstream power was going to be between 38 and 48. However, this upstream power was out of our control on my end.
I own a Motorola MT7711 - (Motorola - Dual-Band AC1900 Router with 24X8 DOCSIS 3.0 Cable Modem and Comcast Xfinity Voice Support - Black.) When I look at the forum it seems like a common issue for people who own their modems.
Is there something I can do fix the issue or do I need to rent a modem from Xfinity to have a permanent solution?
Thank you for your help!

Without seeing those actual stats, here are some things that you can try to improve the connection;
In an effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1000 MHz, bi-directional, and no gold colored garbage from Radio Shack, Home Depot, Target, etc. Splitters should be swapped with known to be good / new ones to test.
Also check the coax cable for any damage such as cuts, nicks, kinks, sharp bends, etc.
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two-way splitter connected directly off of the drop from the street / pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Good luck with it !
