Po tygodniowym pałowaniu się ze sterownikami Madwifi w końcu uzyskałem następujący obraz ifconfig i iwconfig:

Coś nie tak z DHCP?? knetmanager pokazuje sieci bezprzewodowe w tym moją i podczas łączenia dochodzi do 57% i po 30sekundach nie może się połączyć ze wskazaną siecią. Proszę tłumaczyć jak nobowi

[maati1980]

Instalowałem wg tego poradnika viewtopic.php?t=81892 a to znaczy że 0.10.5.6. Mam 8.04 wersję AMD 64 a z http://madwifi.org/ticket/1192 wynika, że powinno to działać.
