[GTALUG] NetworkManager scans wireless every 2min -- solution (finally)

[William Park]

My wireless connection crawls for 20sec every 2min.  NetworkManager was
scanning my wireless network every 2min (iwevent says so).  The problem
is that the scan lasts 20sec, and during that 20sec, I get the following
dmesg messages:

    ieee80211 phy0: rt2x00queue_flush_queue: Warning - Queue 2 failed to flush

and my connection crawls.  The card is Linksys WMP600N (rt2800pci).

I tried different kernels, different driver settings, different
NetworkManager configurations, etc.  Since it's the only wireless card I
have, I couldn't try different card and didn't feel like buying another.

Finally, an accidental click led me to a solution:
    To prevent NetworkManager from scanning, set BSSID to the MAC
    address of access point.
