Duh. I didn't look at the pictures very carefully. Sorry.

Looks like you have interference from someone nearby using Ch 9. I
marked the area on a copy of your screendump in red. I also took the
liberty of tweaking the contrast so that the Ch 9 junk can be more
easily seen:

There's a 20dB signal level difference between your WISP and the
interference, but that's probably enough to cause problems. It also
explains the -88dBm "noise" level.

If you post any more images, please do NOT stretch the image. Just
leave the aspect ratio the same as the original.
