Hi all,

I found a new interference source that might be interesting for others with food service locations in their coverage area.

The Turbochef toaster ovens popular with Subways have side firing microwaves that, in my samples, interfered with channel 11.

Obviously most toaster ovens aren't this discriminant and interfere with the entire 2.4 band.

In this case we only had two APs serving the area and they were otherwise isolated from nearby APs. I just made a new profile and group without channel 11.

Attached is the signal, a time lapse of the signal, and ookla tests done before and during oven use.
