Can't use SSID for authentication (bug?)

 
I have a Lynksys USB (ver 2.6) and I was never able to use this driver,
whatever I try. Finally I can use it... if the access point don't use
the SSID for authentication!

If the access point just accepts clients with the correct ssid
I get from this driver in debug mode:

eth1 param: ssid SpeedTouch892028 (5370656564546F756368383932303238) mode infra ch 10 wep disabled key 0 keylen 0
...
eth1 BSS table (curr=00000000, new=00000000):
0xcd583ba0: bssid 00:02:2d:89:20:28 channel 6 ssid   (20) capa x0001 rates 82 84 0B 16 rssi 5 link 0 noise 0
eth1 BSS table (curr=00000000, new=00000000):
0xcd583ba0: bssid 00:02:2d:89:20:28 channel 6 ssid  peedTouch892028 (20) capa x0001 rates 82 84 0B 16 rssi 6 link 0 noise 0
eth1: state 1 -> 6 (JOINING)
eth1 bss table entry cd583ba0: essid didn't match

(note the changing SSID)

If the access point accepts anyone:

eth1 param: ssid SpeedTouch892028 (5370656564546F756368383932303238) mode infra ch 10 wep disabled key 0 keylen 0
...

eth1 BSS table (curr=00000000, new=00000000):

eth1: state 1 -> 6 (JOINING)
eth1 find_matching_bss: returned cd5834a0

and it works (WEP and no WEP, in 2.4* and 2.6*)

Can this be a bug or is just not supported?
