Why does my cable modem/router keep switching channels?

[Stonepounder]

Recently my cable provider set us all now router/modems promising higher speed with no price increase. (I'm waiting for their follow-up offering me ocean front property in Az.) Yes, we got faster speed, but...

There seems to be an ongoing issue. Periodically I get errors like the following on my troubleshooting logs on the modem/router:

Thu Sep 15 08:52:30 2016 Notice (6) WiFi Interface [wl1] set to Channel 149 (Side-Band Channel:N/A) - Reason:INTERFERENCE

Whenever one of these errors (Yeah, I know they call it a 'Notice') occurs, all connected devices fall off-line and we have to retry our connections (often getting either a 'network change detected' or a DNS error) several times to get reconnected. It also screws up my wireless printer, which then becomes a pain to get back to a point where I can print to it.
These errors are very sporadic. I might go several days without any. I might get one in a day, or I might get 15-20.

So, the question is: What sort of 'interference' could be causing this? Is there any king of shielding I can put up to reduce 'interference' or ...?

I am running Windows 10 on my computers. A fully wireless laptop, a desktop that uses a neat little adapter that basically runs the modem signal through my house wiring, and a couple of tablets running android (also wireless).

Any comments, suggestions, or deeper explanation of what the heck is going on appreciated.

1. manual set of channel

would be ez first try.

My router was set to "auto" as default on 5 GHz,I set it to 157 I think and no problems.

Hope this helps.

Why manually adjust the WiFi channel

If you are experiencing a situation where Provision HD streamer receiver is repeatedly losing a video connection to the transmitter its quite possible the issue is caused by WiFi interference from another network. In this case manually setting the wireless channel used by the HD streamer and/or your home WiFi router will more than likely resolve the problem.

Note: If you are experiencing this issue please continue reading and follow the instructions to manually set the Wireless channel.

3. Well, I set my router Ch 157 on Friday afternoon after I read your post.

And I haven't had a single drop-off since. I'm knocking loudly on wood, but I think you may have helped me fix a real annoyance. Thank you so much!!
