Here is my setup: - An access point running hostapd with an ethernet interface (eth0) and a wireless interface (wlan0, the wifi usb dongle) which are bridge together (br0) - a computer directly (or through a switch with other computer) connected to the AP's eth0 - two computers associated to wlan0 (they all are on Linux) Here is what I can do: - Stations can associate with the wifi usb dongle - Stations can ping, ssh,... the AP - Stations can ping, ssh,... any other stations - Stations can ping, ssh,... any computers on the LAN - AP can ping any computers on the LAN - Computers on the LAN can ping the AP And what I can't do: - Computers on the LAN can't ping the stations (Destination Host Unreachable) - AP can't ping the stations I ran wireshark on a computer on the LAN, on the AP (here I used tcpdump on all interfaces because I don't have the possibility to have X) and on a stations. I would say that's a problem with ARP packets. When I try to ping a station from the AP or a LAN computer, ARP requests arrive to the AP (I see them on eth0, wlan0 and br0), but they don't arrive to the stations (I can't see any ARP packets in the air and I use a different wireless interface to monitor than the one that is associated with the AP). When with that station I ping the AP (or the lan computer, it doesn't matter), the first ping (from AP or lan) works until I stop the ping started on the station. I was wondering if the fix I did (the one we were discussing the 5th March) on the rt73 driver may be the cause of that problem. Best regards, Alexandre Becholey
