Hello,

I have an ath9k in a bridge; the other network card is a 3com 
wired nic.

Basically the setup is that I have a media centre PC 
connected to the rest of my network over wifi, and my new TV 
has an wired port.  So my plan was to plug the TV into the 
media centre, bridge the wired and wifi interfaces, thereby 
giving the TV access to the network and internet.

The TV can see the uPnP server on the media PC that it is 
directly connected to, but cannot see the rest of the 
network.

If I tcpdump on the eth and wlan interfaces, I can see its 
arp requests appear on both interfaces - so the bridge is 
seemingly working at the OS level.

But the arp doesn't make it out to the rest of the network. 
The ath9k card is connected to a Linksys WRT610N, flashed 
with dd-wrt, so I can run tcpdump on it.

I don't see the arp requests coming from the media PC arrive 
at the wrt610N.

I have read that some wifi card drivers do not support 
forwarding packets that have a different source MAC address 
than the card itself.  Is this the case with the ath9k 
drivers, or could something else be getting in the way?

Thanks,

Paul
