[Avila] Madwifi

Wed Jun 21 03:40:43 EDT 2006

On a (kind of) related note, is anyone having problems getting a madwifi
client to associate to access points on 802.11b (2.4GHz) at distance? I can
only seem to get it to associate on the bench, but it fails even at one
mile. (wrap, rb532, 2348-4, madwifi 0.9.0). 
Cheers,
Dave.
