I know it's working, as i hooked up a network cable and i can access internet and other network devices.
Only thing is can't get SSID. I used some guides on the forum (turning security off, basically) but still i can't get the interface to show the option we you can select to broadcast SSID.
Using the factory-to-ddwrt_patched_WA730RE_V2.bin attached at the top of this thread (you must be logged in in order to see it), I was able to get my WA730RE v2 flashed.
Then I proceeded to setup the client bridge (no repeater option available, but it is equivalent for most cases as far as I know). I used instructions from http://dd-wrt.com/wiki/index.php/Repeater_Bridge. As far as I can tell, both set of instructions under 1) Broadcom and 2) Qualcomm Atheros work fine. Both are essentially the same except that #2 does not have a) Setup -> Advanced Routing tab -> Set Operating mode to "Router" b) Assign WAN Port to Switch : Optionally enable this to use the WAN port as another LAN port and c) Disable firewall. I did #2 and all a, b and c (from the Broadcom section).
