Modem drops internet connection frequently

Thanks EG. See my reply to Xfinity Seth for details, but the main issue is I don't have a valid login for the link you provided.

@tullyguy Have you tried to reach the manufacture of the modem for the login information? 

@XfinityDena​ 

Can you poll their modem remotely to see their signal status values ?

 Thanks for the reply. I don't have the knowledge or skills to access the modem's signal status as EG suggests. I suppose I registered the modem when I bought it but I don't have a record of the login name and password. I have unplugged the modem multiple times although it usually reboots on its own and normal signal strength is restored immediately. The modem just dropped a connection a few minutes ago and rebooted automatically. The frequency of this happening is what is annoying. If it were only once or twice a month, it would't be a big deal. In the last two weeks it has dropped the signal five times, that I'm aware of. We have a VOIP phone connected to the Arris T25 and losing the signal during a call is especially upsetting. I'm 79 years old and have been playing or working with computers since they used a portable b&w TV for a monitor and you wrote programs in basic and saved your creation on an audio tape cassette. Crashing was the most common experience.

What happens when you click the blue colored link that I posted ? Or enter that address manually in your browser's address bar ? Do you see a login page ? If so, enter username for the default username and password for the default password. Any joy ?

@user_n0e1mt​ thank you for taking time to reach out over Xfinity Forums, you've contacted the right place for assistance and would like to help with the device connection issue. I appreciate the information you've provided, it's helpful knowing you're not experiencing the issue on the computer but the dropping of the network connection happens on your phone. Have you attempted any of these troubleshooting steps: 

How does a phone enter safe mode?  It's my phone that keeps dropping internet.  My computer does not.  Every time my phone re-conneects and goes on line, it drops the internet within an hour (usually within minutes).
