Hi!
This is my /etc/network/interfaces file:
auto eth2
iface eth2 inet manual
wpa-sriver wext
wpa-roam /etc/wpa_supplicant/wpa_supplicant.conf
iface office inet dhcp
iface anywhere inet dhcp
I do not use the wpa_supplicant.conf file to configure networking anymore and have everything
in the /etc/network/interfaces file:I have a static IP configuration but it should also work with dhcp. What I don´t use is roaming. I have a configuration fiele set up for every location I usualy visit and written a script to replace the network settings accordingly.
iface eth2 intet static wpa-driver wext wpa-ssid MySSID wpa-psk WPA-Key (created with wpa_passprase) address 192.x.x.x netmask 255.x.x.x network 192.x.x.x broadcast 192.x.x.x gateway 192.x.x.x dns-nameservers 3nameservershere dns-search localdomainTry out if this works for you. I find it better to have all configuration in just one file so I can more easily replace it and restart networking when I am at another location and need to reconfigure networking.
Good Luck!
