internet drops regularly

Due to "no internet" I have to reboot my modem twice a day, sometimes in the middle of work meeting or TV streaming. It starts happening about two weeks ago and becoming worse. Xfinity app is useless without internet, and when it comes back there are "no outages in your area" and "everything is fine". AI assistant is dumb as 30-line code.

What do the modem's signal status values look like ? Try getting them here; http://192.168.100.1 or here http://10.0.0.1 


Please copy all of the text in its entirety of the *Downstream Power Levels*, the *SNR's* (Signal to Noise Ratios), and the *Upstream Power Level* numbers and paste them into your next post.


What is the exact make and model number of the modem / gateway device ?

I login to 192.168.100.1 but I cannot find an option to get SNR and Power Levels from the Arris setup page

Start on page 31 thru 34 of the user manual here for access instructions;

https://www.manua.ls/arris/surfboard-sbg7400ac2/manual?p=32 

On page 34 and you'll see instructions for the "WAN setup". The signal stats may be under that tab.

Why does this have to go private at this point ?
