LinkSys WPC11 (NIC: id=0x801b v1.0.0) doesn't seem to do the 
JoinRequests after I pass it in host_roaming mode:

In fact, after a scan  (initiated as a result of specifying a new 
preferred_ap or automatically by the firmaware because of low quality 
the driver correctly send a JoinRequest that doesn't complete...

I tried it with both 0.0.1 and 0.0.2 versions of the driver.

Other older cards (Farallon SkyLine 11Mb) work fine...

wlan0: ScanResults: Reserved=0x0b84 ScanReason=1
wlan0: Preferred AP BSSID 00:60:1d:04:ec:af
wlan0: using preferred AP selection
wlan0: JoinRequest: BSSID=00:60:1d:04:ec:af channel=11
wlan0: ScanResults: Reserved=0x0cf0 ScanReason=2
wlan0: last join request has not yet been completed - waiting for it 
before issuing new one

lso, I would like to reiterate a question from a previous mail: it could 
be possible to do the JoinRequest after specifying a preferred_ap 
without initiating a scan (the scan consumes usually between 200 and 
400ms, depending on the number of channels scanned and the activity of 
each of these channels, and I think that only the association could take 
only 10-20ms) ? Canthe driver memorize the ap's channel from a previous 
scan or can we send the channel, too to the driver by a modified
