Spectral Analysis - Can you explain this?

Take a look at this spectral analysis from one of our access points. We were having loads of issues connecting to the access point on Ch11. I have changed the AP to Ch6 to see if this fixes the issue.

If you have ideas what might be causing the graph to look like this any help would be appreciated.

Hi Dan, it''s clearly some kind of narrowband interference, though exactly what is difficult to tell from this image.

What's located near the access point ?

Looks like a continuous transmitter.
Got any motion detectors? Buildings' alarm system?
