forcing association with a specific BSSID

[Joshua ChaitinPollak]

Hello,

I'm trying to force my clients to connect with specific BSSIDs, and  
association seems to work ok, but packets don't seem to get out. This  
is with wpa_supplicant 0.5.7 and madwifi-ng 0.9.3.

I'm using the following commands to force the BSSID:

wpa_cli ap_scan 2
<first, remove all existing networks>
wpa_cli -iath0 add_network
wpa_cli -iath0 set_network 0 ssid $SSID
wpa_cli -iath0 set_network 0 bssid $BSSID
wpa_cli -iath0 set_network 0 key_mgmt NONE
wpa_cli -iath0 set_network 0 wep_key0 $PSK
wpa_cli -iath0 set_network 0 wep_tx_keyidx 0

I've posted the output of iwconfig and ifconfig below. Notice that  
the bit rate and link quality seem to imply correct association (so  
does "wpa_cli status", see later). I also noticed nwid is really  
high, but we have quite a few wireless networks here, so I think  
that's ok.

Finally, notice that the RX packets is pretty high, but all of the TX  
packets where dropped.

I'm at a loss at how to debug this, so any suggestions would be  
appreciated.
