Subject: [gentoo-user] Can't Decrypt WEP Packets After Upgrade From 2.6.23 to 2.6.25

1 Ever since I upgraded my gentoo-sources kernel from 2.6.23 to 2.6.25, I
2 can no longer see packets on my wireless network for any device other
3 than my own. The tcpdump output looks like this:

24 I've Googled for an answer and think that my problem is that I am unable
25 to decrypt WEP packets for any device other than my own. This is a
26 simple 64 bit WEP network in my home. Unfortunately I did not find
27 anything that applied to my situation.

29 One thing different about my new kernel config is that because I have a
30 Broadcom card, I moved to the new b43 driver instead of the old
31 b43_legacy driver. I am using version 4 firmware however I had the same
32 problem with version 3 firmware. I was hoping that would fix it but no
33 luck.
34
35 I am also using the new MAC80211 stack instead of the older IEEE80211 stack.
36
37 Any ideas on what I have done wrong?
