Intermittent Signal Loss During Evenings at Apartment Complex

I pay for 1,200 mbps internet, and get that most of the time, but every evening I experience intermittent signal loss. This can be as frequent as once every few minutes and can last up to 30 seconds at a time. I am connected directly with an Ethernet cable and know that it is not an issue with any of my equipment. Is there anything that can be done to improve the consistency of my signal? I live in an apartment complex in a major city. My internet was much more reliable when I live in a rural area. Please see the image below. Thank you.

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 ?

Hello,

Thank you for the assistance, but neither link works for me. I just get a page showing

"Managing your home network settings is now easier than ever. To manage your gateway settings and other features, please download the Xfinity xFi app."

Using the app I can not find anything showing a log.

I believe that I have a Gateway XB8 CGM4981COM

Have you tried enabling the admin tool access feature ?

They're all ok. Not certain, but this sounds typical of being caused by a peak usage time capacity / traffic congestion problem on your local cable segment / node. If so, there is not much that you can do about it except to complain to them persistently and to try to get your immediate neighbors to join in. The more neighbors that complain, the more effective it will be. Good luck !
