But I think we first need=20 > the bridge running in a "easy" situation, with no security When you setup the bridge at the beginning, the br0 interface takes the=20 MAC address of eth1. Then you add eth0 and the bridge takes the MAC=20 address of eth0, because it is lower. Can you try to use the bridge-hw option of /etc/network/interfaces, to=20 force the bridge MAC address to the MAC address of the wireless=20 interface ? This might solve the communication problem for UBUNTU=20 SERVER... but unfortunately probably not for the bridging function. That beeing said, Jonathan might be right about the need for WDS... Can=20 you have a look at the AP configuration, searching for a WDS setup ?=20 Because if it works on Windows, without WDS (if disabled or unavailable=20 on the AP), then we can assume that WDS is not required, even on Linux=20 (the wifi interface is able to receive traffic for another MAC). If the AP is WDS enabled, then... WDS might be necessary... and nothing=20 can be done if the driver for you wifi interface does not support it... Nicolas.
