Also from what I have read, every scan drops your connection for a while, which might be a problem for bad wifi drivers, where the scan can take 15+ seconds so doing this more often is not a good idea. Other thing I would change is to try to repeat the scan if it fails only for the first time (when you open the applet), then I don't think it's necessary to keep spamming NetworkManager with our requests.

  I think it's reasonable enough and also as I mentioned above, wifi scanning drops your connection for a while, there is no reason to drop it more often, especially when we will have a fresh scan as soon as possible.

  I didn't mean we shouldn't be doing an attempt every 2 seconds, I meant that we should go through this retry logic only in case of initial scan, but keep it that way. Just set the interval back to 15s.
