Hello folks,
Thanks for the suggestions -- here are a few questions I can answer from
earlier today:
1) I didn't realize there was a subtle difference between WEP104 and
WEP128. What I can tell you is that the WEP AP is running Tomato 1.23,
and is set to WEP 128-bit. However, the key I'm using is only 104
bits. This probably means I'm actually using WEP104.
2) I'm definitely not using madwifi in either case -- I've always used
the ath5k driver on this machine.
3) As far as I can tell, there are no modparams being used with ath5k.
I checked both /etc/modprobe.d and /etc/sysctl.conf (I'm not sure if the
latter affects modules or not, actually - I think it might depend on the
module).
4) I realize WPA+TKIP is more secure and I would use it if I could, but
I have some old devices that don't support WPA it so I'm limited to WEP.
5) I use -Dwext with wpa_supplicant when I *do* use WPA+TKIP networks.
Also, FWIW:
# lsmod | grep ath
ath5k 127364 0
mac80211 155788 1 ath5k
ath 7708 1 ath5k
cfg80211 90364 3 ath5k,mac80211,ath
led_class 4000 1 ath5k
I'm not sure when I might have a chance to bisect, but will certainly
let you know if I do.
Best regards,
Don

For the record, WEP104 and WEP128 are the same thing. The smaller number
makes it explicit that the 24-bit IV is transmitted in the open. The same
thing applies to WEP40 and WEP64.
Only one problem there is another, nonstandard WEP type where the
actual key is 128-bit, and this is also sometimes referred to as
WEP128 (with the same metric as WEP64, this one would be WEP152). Same
goes for "WEP228/WEP256/WEP280".
Yea, I think ath hw supports that too:
#define AR5K_KEYTABLE_TYPE_40 0x00000000
#define AR5K_KEYTABLE_TYPE_104 0x00000001
#define AR5K_KEYTABLE_TYPE_128 0x00000003
at least that's what I assumed it meant. But there's no way to set it
from mac80211 (nor should there be).
