We did a lot of wireless (2.4GHz range) sensor development at my last job. It was a rule of thumb to avoid any testing at lunch time since the microwave generated so much interference, everything would fail when someone wanted to heat up their meal.
Ugh... Mom and the microwave were a scourge back in the days of yore when I hosted servers for friends in various games. I was hardwired into the router as "the keeper of the hardware", but the wireless would just get schlocked every time she heated up her coffee.
And Mom ran on coffee. Lotsa coffee. Sometimes I think she just did it because she didn't hear enough complaints coming out of the speakers.
I rejoiced the day that thing died. She's now got an even beefier one, but it doesn't interfere on the 5ghz bands at all, and I'm not testing the 2.4 out of respect to the spirit of that ole menace.
