Re: hardware WEP encryption in 1.4.9

Just wondering if card-based WEP encryption might be broken in hostap mode because they added provisions for per-client keys? Also, I guess that unless that is indeed the case (and somebody finds out how it works...), per-client keys would still require host-based encryption?

Just my EUR 0.02...
