RF

High Res Wifi Signal Mapping
RF is an often used abbreviation for Radio Frequency, that part of the electromagnetic spectrum where all kinds of radio signals are found.

I've been having trouble with the WiFi reception on my Chromebook. It varies from one moment to the next. I was trying to watch a video about the upcoming solar eclipse a few minutes ago and my WiFi connection is so bad that the video is unwatchable, so I go looking for an explanation. tom's HARDWARE has one:

While huge drops in wireless speed are not "normal" they are very common and can happen for a number of reasons, the most common being interference from other 2.4GHz sources, including other nearby networks, wireless phones, speakers, baby monitors, microwave ovens, etc.

Then on reddit I find a link to above video. Now, of course, my wireless connection is perfect. I'm going back to wires, well, as soon as I get my Linux box working again. There is no Ethernet jack on my Chromebook.
