Ten days ago I installed my new Linksys Router WRT45G router and set up a wireless bridge for my home network. I had some problems with getting everything working like I wanted it to - see my post.

Today I took another attempt and was successful. Now I got a secure wireless connection in bridge mode. I wanted WPA because it is much more secure than WEP and in bridge mode it is easier to reach all my devices. Here is my configuration:

nvram set wl0_mode=wet
nvram set lan_ifnames="vlan0 eth1"
nvram set wan_ifname=vlan1
lan_gateway=192.168.1.254
lan_dns=112.23.54.5

ifdown wan
nvram set wl0_ssid=MYSSID
nvram set wl0_channel=7
nvram set wl0_akm=psk
nvram set wl0_crypto=aes
nvram set wl0_wpa_psk=WPAKEY
nvram set wl0_auth=0
ifup wan; /sbin/wifi

nvram commit;

For more information about the parameters see the OpenWRT wiki.
