> but you need to hunt down EMI sources, before you can properly use it.

Do you have any recommendations for doing this? I have some source that interferes every 11 seconds for a second or so. It causes packet loss with my wifi (2.5 and 5GHz), and makes my bluetooth game controllers really frustrating to use, since input are missed every time it does it. I assume it's in the microwave range.

I'm familiar with RF test equipment, and I've thought about renting a spectrum analyzer, but I assume there's maybe some cheaper way.

You could get an rtlsdr dongle cheap and use it as a spectrum analyzer. There are command line utilities for that task in with the drivers online.

they don't go up to the 2.4/5Ghz range though, they max out at about 1.7

Yeah, but it seems he's got a broadband noise source, likely the 2.4 Ghz is a harmonic of something that is within their range.
