Can you also explain why you are trying to use bridge ? Are you just trying to share a common IP address between two links (Ethernet and wifi), in order to switch automatically to wifi when you unplug the Ethernet wire, without loosing any active connections ? If this is what you are trying to do, you might try the bonding module instead of bridge, and have a look at the ifenslave-2.6 package from Debian, which should work on Ubuntu. This package enhance the ifupdown system and allow you to bond an Ethernet and a Wifi link, in an active/backup mode. An "Ethernet+wifi" example configuration is provided in the documentation. You configuration should look like this : auto bond0 iface bond0 inet dhcp bond-slaves eth0 bond-mode 1 bond-miimon 100 bond-primary eth0 iface eth0 inet manual # Useless, unless NetworkManager is enabled on you system. auto eth1 iface eth1 inet manual bond-master bond0 bond-give-a-chance 10 wpa-bridge bond0 wpa-driver wext wpa-ssid ##SSID## wpa-ap-scan 1 wpa-proto RSN wpa-pariwire CCMP wpa-group CCMP wpa-key-mgmt WPA-PSK wpa-psk ##PSK KEY## 'hope this help.
