At the firmware level, most wireless cards will refuse to transmit/receive packets with other MAC addresses, making them useless for AP or bridging. Yours is apparently not one of those since bridging works in Windows (or else the Windows bridge code does transparent routing w/MAC address replacement, rather like NAT or PAT but working at layer 2 instead of 3). That's why I suggested testing for the DHCP discover on a different wireless node. > > You should either turn on STP so loops can be detected and prevented > or unplug eth0 to simulate that scenario. > > If I unplug eth0, the situation stays the same.
