I’ve got a problem with the setup of my dwl-7100ap (running r10217) that I can’t seem to solve or understand why it is happening! The thing is that broadcasts don’t get forwarded through the AP the way they should so stuff like dhcp and arp does not work.

I’ve got a notebook that I want to connect wirelessly to my network (and the network setup as a whole is quite simple). On the “wired†-side I got a broadband router that also acts as dhcp-server for my network and a linux-server that exports disk through samba among other things. The dwl-7100ap has one Ethernet port that is connected to the wired lan and two wireless networks (2.4GHz and 5GHz) that are all bridged together in a bridge to keep the same subnet on both wired and wireless networks. (Btw everything worked OK before I installed OpenWrt on the AP)
The wireless association (with WPA) works so I get a working link between the client and the AP, but broadcasts don't get forwarded as they should so the clients dhcp-requests never reaches the dhcp-server and no  arp-requests get through from either side etc so no actual IP-traffic can take place.

Now here’s the thing that I find strange; according to iptables –L –v no packets get dropped due to firewall rules and brctl shows that the bridge is setup as it is supposed to. AND if I enter a static IP on the client and manually add the mac-adresses in the arp-tables on the machines ping, ssh etc works! So “point to point† IP-traffic work, it’s just broadcasts that get lost?

Does anyone have an idea what might be wrong?
