I don't know it this is related, but something changed with the WEP-key index. 
On my EeePC I had to change my wpa_supplicant.conf file to use 
wep_tx_keyidx=0 and wep_key0=mywepkey before I could get it to work. 
I the past it always worked with wep_tx_keyidx=1 and wep_key1=xxxxx.

The funny thing is that ifconfig reports it as deftxkey 1 and wepkey 1 if I 
use index 0 in wpa_supplicant and ifconfig will report deftxkey 2 and wepkey 
2 if I use index 1 in wpa_supplicant.conf
