Hi Roger - I have struggled through WPA several times in the last couple of months.
Firstly, WPA support under linux demands that you run a daemon called wpa_supplicant. Some distros package this as wpasupplicant. Without this you simply don't get WPA. wpa_supplicant handles all the password stuff as well as selecting the best network available from a priority list. You can see what its doing by running wpa_cli in another window. Also, I believe that wlan0 (or wifi0 as mine is) is not a real device.... Instead it's a master device that can provide multiple athX devices on the same card so that you can do lots of cool stuff. Which drivers are you using? Madwifi, madwifi-ng (me), or hostap, or something else? -----Original Message----- From: Roger Searle [mailto:[EMAIL PROTECTED] Sent: Tuesday, 25 July 2006 7:34 p.m. To: [email protected] Subject: no dhcpoffer I have a functional wireless card now, but when the card goes looking for the router no dhcpoffer is received by the card.

No working leases in persistent database - sleeping. I have set the router so that it is NOT filtering by MAC address, it is WPA pre-shared key, and I have checked there is a match with the channel, ssid and password from /etc/network/interfaces: auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto eth1 iface eth1 inet dhcp auto eth2 iface eth2 inet dhcp auto ath0 iface ath0 inet dhcp pre-up /sbin/iwpriv ath0 mode 0 pre-up /sbin/iwconfig ath0 essid rnsRouter channel 10 key abcde12345 auto wlan0 iface wlan0 inet dhcp Anyone have any suggestions what I could do? Cheers, Roger
