We're currently blocked on testing due to this.  Here's the related gaia issue:

This is the right approach. I have a cleaned-up patch as well.

mwu, I hope you don't mind reviewing this... basically this patch lets us not do the active/passive scanning stuff if the driver doesn't support it.

Followup

Not true - passive scans are fully supported with a nl80211 driver. wpa_supplicant just isn't exposing an interface to do it, and why should it? An active scan is what you want 98% of the time. WifiWorker.js probably shouldn't care about scan modes at all.

This is still reproducible on a daily otoro build of 7-17-2012.   

REpro:
1) load settings > wifi
2) uncheck the wifi checkbox  (assuming you had networks found before)
3) recheck the wifi checkbox
4) Verify no networks are ever scanned or found again.

That is a different issue.

Does this one look like a duplicate issue by Bug 782020 I just fired?

Resolving this bug since the main issue is already fixed. I don't think we really need the follow up so I've cleared review, but we can do that in another bug if you think that check should be there.
