NM may well initiate a scan, but unfortunately there's no way for the supplicant to report that the scan request failed (due to its internal code structure), so NetworkManager doesn't know that it needs to request another scan when the first one fails. It turns out that some drivers (especially ath5k) like to deny scans quite a bit. We need more work in this area, and we may be able to fix up the supplicant to provide "scan failed" notifications that we can use but that'll take more work. NM should, however, request another scan within 20 seconds or so. But of course if that one fails for some reason, then the next request won't be for 40 seconds after that.
