If it isn't broken, why fix it.. I haven't seen 1.4.9 f/w for old Prism2
cards (HFA3841). The latest version I have tested with such card is
1.3.4. Newer images might be available, but it might require some

Are you sure that the wlan card would be any better in WEP processing?
Quite many of the older Prism2 cards have quite poor WEP performance
(throughput dropping from ca. 5.5 Mbps to 2.5 Mbps when enabling WEP)..
You might like to first confirm that you can get better results by
testing WEP e.g. in ad-hoc mode.
If the card-based WEP is fast enough and you manage to find 1.4.9 f/w
image for your card, remember also to upgrade Host AP driver since the
older versions were hard coded to use host-based WEP in Master mode no
matter what f/w version was used.
