Hi everyone, my english is very poor.

I have two atheros2316 chipset, and it's burn kamikaze7.09 from official website(http://downloads.openwrt.org/kamikaze/7.09/atheros-2.6/), and kernel is openwrt-atheros-2.6-vmlinux.lzma, rootfs is openwrt-atheros-2.6-root.jffs2-64k. And they run a good time to load the module does not prompt an error.

My question is below:
this is my network topology

AP------(Through a wireless connection)--------client(sta)---------(Through a LAN connection)----------PC(windows)
AP:       ip:192.168.100.240
Client:   ip:192.168.100.241
PC:       ip:192.168.100.242

And i telnet AP and client.
In AP cmd line i can ping client(ps: ping 192.168.100.241 ok), but i can't ping PC (ps: ping 192.168.100.242 ) Why ???
In Client cmd line i can ping AP, and PC.
In PC cmd line i can ping Client, but i can't ping AP, Why??

Bestregards

what is your network setting  (i mean ... routing ,bridging ,firewall . ....)
i think you have to setup a bridge or routing between wan (in this case wlan iface) and lan (connected to windows pc) and edit firewall setting
by default is openwrt in mode

wan >> [routing] >> (lan{switch} and wlan bridged together)

and my firewall is closed. Can you give me some more detailed information.

Have other views??
thanks ...

From looking at your schema above it looks to me like you're trying to set up a bridged client connection. This is not possible with OpenWrt and Atheros, either use a routed setup or switch to Gargoyle / DD-Wrt for that - they have support for that kind of operation mode.

Hi jow thanks a lot.
This is a chip problem or driver problem? atheros 2313a to solve this problem??You mean i was use DD-wrt driver? Give you the trouble......
Bestregards
