Another possibility is a leaky microwave oven in the vicinity
This is an urban legend and an excuse I was using when I was in tech
support.
It's real. Try it yourself - run iperf for 2 minutes, display the
bandwidth report every second and then start the microwave for 1
minute.
I get the thruput cut in half or or more when the microwave is on.
Which is an improvement on the previous microwave which used to kill a
wireless connection. (which was super annoying when the wife was doing
work-from-home & I wasn't allowed to use the microwave _at_all_ during
the day. I suspect that's the reason she got a toaster oven)
Is it fairly well-known that microwave ovens interfere the most on channel
11?
I just tried linssid again and there's a bunch of APs on channel 1 &
6, one on channel 2 and two on channel 8. Nothing on channel 11.
That, again probably, would be because the microwave does NOT transmit
an SID,
It doesn't transmit anything resembling a wifi frame (packet?), it's
just noise as far as the wifi interface knows.. and not something that
shows up on a wifi analyzer like linssid.
You need a spectrum analyzer to see wifi noise/interference. I just
took a quick look again for an affordable spectrum analyzer & didn't
see anything. Then again, my definition of "affordable" is under $50
so I suppose that's not to surprising.
