Inconsistent internet connection

@flatlander3​ Using the log in processes to access my gateway has logged me in to a separate internet source in the area, My wifi and internet name goes by A for example and the router internet goes by B. In addition there have been and are many additional devices on my network that I have been frustrated by in the past. Is it possible that there is an issue causing both my router (A) and the other xfinity internet source (B) to assume that they are the same network?  I'd rather not continue the proccess in fear of tampering with someone else's internet or router settings.

@flatlander3​ could this be the cause of my inconsistent connection? I do hate to bug you on Christmas by the way and I really appreciate the assistance. I just have quite the pet peeve involving not understanding a problem and I'd really like to become more knowledgeable about issues like this in the future. 

@NicholasP1​   Oh my.  Much worse than that.  But yes.  You are struggling with an ad-hoc network and weird routing since everyone (your neighbors) are meshed together.   

You have unknown devices on your network.  You are an unknown device on someone else's. You have unknown activity on your network.  You are exposed to data breach, privacy violation, malware, virus infection and also, and most importantly criminal activity you can be charged with.  We're talking about the kid p0rn thing or worse.  It's YOUR door that will get kicked in if there is criminal activity.

First thing you want to do is disconnect the coax.  Then try to log into your gateway at http://10.0.0.1  username=admin, password=password unless you changed it.  Now shut off MoCA in your gateway settings.  With no coax, you won't be on your neighbors network. 

Verify that by looking at the CM MAC and MAC address on the sticker on your gateway, and compare to the connection on the admin page you logged into.  You want MoCA OFF for now.

MoCA turn itself back on with a reboot or firmware issue, then you'll have the same problem. 

If you have no coax connected devices, you can screw an MoCA point of entry filter to the back of your gateway to block the signal/isolate your network.  It uses a higher frequency than your internet connection.  It will block that signal. 

If you do have coax devices, like a cable TV set top box, it goes where the service enters your residence on the coax splitter that feeds your other coax jacks.  You are trying to isolate yourself.

You can get an MoCA point of entry filter at amazon for $10, or walmart's site.  You may be able to get one for free at an Xfinity store if there is one by you.  Search for "MoCA PoE filter".
