Ethernet link interfering with wifi signal

I have been experiencing intermittent wifi issues for the past 1-2 years. I had aways thought it was my internet service provider - although interestingly, turning wifi off and on again on my laptop, usually solved the issue (temporarily).
Then last week I tried something new: I disconnected the ethernet cable that connects to my freebsd server (running v12.1) directly to the router. To my surprise, I've not been having any wifi issues since! Unfortunately this is a tradeoff: I no longer have a freebsd server I can access :)

I am happy to provide any additional info to help debug...

Please be specific about "wifi issues". In the meantime, if you are on a 2.4 GHz WiFi network, try different channels, especially 6, 11 and 1.

The issue is likely to do with you having two routes to the internet using two different IP addresses. Setting a static IP on your ethernet with no default gateway will probably have the same effect as yanking the cable.

I tried channel 6 (default was 1); and that seemed to do the trick.

Yeah, I don't think FreeBSD had much to do with the circumstances surrounding this problem.
