Thanks. I may take you up on the offer sometime.

If only I could get my wifi signal to quit bouncing in and out. It’s better now but for some time it run fine for a few days but then suddenly would fall from 25 mpbs to less than one. Forcing a channel change would cure it for a few days. I blame Verizon but the claim innocence.

Most likely, others are close by you on the same channel.

Spread spectrum is supposed to allow multiple users to share the same channel, but it doesn't work too well in close proximity; there is still interference.

Try getting an directional antenna that points your router's "beam" in one direction, and make it the most "lived in" part of your house.

If changing the channel fixed the problem, you are experiencing interference because someone else is using that channel.

There are only a handful of WiFi channels that don't overlap:

But, if someone is using a router with 802.11n, there is even few non-overlapping channels:

You might want to invest in an 802.11ac router. That will move you into the 5GHz band, where there should be less interference. You can just plug it into one of the ports on your Verizon router.
