Constant WiFi Dropping and Reconnectiing

Hello! I'm having an issue with my wifi in my home constantly dropping and reconnecting. I've googled everything I can and called my internet and modem/router companies. Nobody can figure this out and they all point the finger at each other. I'm hoping someone can chime in here.

I had a wireless internet provider for over 10 years without issue. This started out of the blue one day back a few months ago. Anything connected through wifi in my home would constantly disconnect and then reconnect just as rapidly as possible. This was using a Belkin N450 Router. This provider did not use a modem. I called the ISP and they said it sounded like a router issue. I called Belkin and spend countless hours on the phone with them. They couldn't figure it out so they sent a brand new one to me. It did the same thing right out of the box. I went back and forth with the ISP and they had no ideas. I cancelled their service thinking it might be them and just not knowing how to fix it.

Fast forward to now. I have Comcast service with a brand new Arris SBG6700-AC. It does the exact same thing. And again each company is pointing their finger at eachother. This is not an every now and again thing. It constantly does this. I sit there and watch my phone connect and reconnect over and over.

A few things here:

All cell phones and tablets connect with Wifi at work and other places as normal.

I can't connect my phones, tablets, tv, printer or Chromecast at all.

I've disconnected everything to see if I can get even one device to stay connected and can't.

I don't know why this would happen with 3 different modems and 2 different providers.

We don't have a home phone with same band wireless interference.

The Belkin guys thought there must be some new radio interference in my neighborhood, but none of my neighbors are having issues. Our houses are very close together.

Just last night, I had the Arris guys tell me that the Upstream Bonder channels should not be over 50. Some of mine were reading a little higher than that. They said I had to call Comcast and have them do something to lower that with the line into the house. I have no idea what this even means. When I called Comcast. they said that doesn't make any sense and wouldn't be the problem. I tend to agree with this as was happening with my previous provider that only had an antenna on my roof.

I think that's all for now. This has been going on for months and it's extremely frustrating. Any ideas?

how many splitters do you have between the outside box and your router? too many will cause the same problem - especially if the wiring and splitters are getting old. I had the same issue a while back. turned out one too many splitters. I think the tech said no more than two. he pulled one, replace the others and the service stopped dropping.

Same here, but I have a probable fix.

Turn off guest mode and adjust the 2.4ghz bandwidth to 20/40Mhz under "Network Name". Not sure which is clashing, but I suspect it tries to overload itself with the guest mode.

Given that you have had wireless Internet sync problems with two Belkin N450 routers with one ISP and the same problems with an Arris SBG6700-AC router, the modems and/or routers do not seem to be the source of the intermittent sync of your Internet connection. Since your Internet access is through a wireless plan requiring no telephone line or coax cable running to your house, the problem lies somewhere between the antenna for your wireless Internet and the router. You would want to have the splitters, internal wiring and any other infrastructure related to transmitting Internet signals from the antenna to your router since you were getting wireless Internet without frequent disconnects and reconnects until recently. Comcast, your new ISP should be able to run tests on your wireless Internet infrastructure.
