I have a Linksys PCI wireless card that is being attached by "ral" driver:

10.0 on pci0
ral0: MAC/BBP RT2561C, RF RT2527
ral0: Ethernet address: 00:18:f8:2e:40:25
ral0: [ITHREAD]
But when I do 'ifconfig ral0 list caps' it returns:
ral0=2181e500<IBSS,HOSTAP,TXPMGT,SHSLOT,SHPREAMBLE,MONITOR,WPA1,WPA2,BGSCAN>
and WEP isn't there.
This looks amazing since WEP is older and very widespread.
I am about to do a talk on WEP versus WPA for a course in internet
security. I became acquainted with the protocols through a
60 minutes story.

WEP is not fully secure. WPA or WPA2 is the improvement. The
above story notes that American businesses are in arears with
respect to properly upgrading the wireless routers that they
use for financial processing.
So how can I tell if this card can't really support WEP or it's the driver
that
can't support it?
WEP is always supported. The WEP capability bit means the driver uses the
hardware. Many driver writers were too lazy to implement full driver support
and just fall back on the host to do crypto.
Also command:
ifconfig ral0 inet 192.168.0.1 netmask 255.255.255.0 ssid freebsdap wepmode
on
weptxkey 3 wepkey 3:0x3456789012 authmode open mode 11g mediaopt hostap
succeeds though CAPS doesn't have WEP.
Isn't this a bug?
No, see above.
