I bought the G300N based on its advertised claims for the sole purpose of being a wireless bridge in my home network so as to add internet access for my home-theater components in my downstairs . LIke others, I have spent many hours trying to configure my WHR-HP-G300N as a wireless bridge. My AP is a Linksys WRT310Nv1 router, which does not support WDS, so I do not have that option. As others have posted, I can see the G300N as a client on my 310N, so I know the wireless is setup properly (it will get an IP address in Client mode as well). My laptop gets IP addresses from the G300N if DHCP is enabled, so I know the router side of things is working. Obviously the packets are not getting routed or forwarded to/from the radios MAC to the router.
I am very adept now with the process: Factory (hard) reset; Change IP address and gateway. Release IP address on laptop to work on changed subnet; Change wireless configuration to match 310N (I always check to make sure the radios are connected). Reboot. Change to Client Bridge. Change Firewall settings; Change Gateway to Router. Save; reboot; Rinse and repeat, changing up the order once in a while just to keep things fresh (basically following http://www.dd-wrt.com/wiki/index.php/Client_Bridged instructions).
My assumption is that the router (eth0) and the wireless (ath0) interfaces must be bridged, or a static route must be set up between them to make this work, which Paul hints at in his instructions earlier in this thread, but the internal bridges apply to WDS configurations and I can't get it to work. I have tried many combinations, trying to think "logically" through the process, and while I know some about networking, I don't know enough to fully understand the interconnections and the internal neworking configurations and routes and what I should be seting up. Of course, I shouldn't have to for setting up a basic, "advertised" capability.
I have the original box out and am getting ready to send back to the store and buy a router that will actually work and doesn't require a bottle of aspirin for setup. However, I thought I would try a deperation cry for help before doing so.
Let me ask the most fundamental question to the Buffalo folks: Can the G300N ever work as aClient (wireless) bridge with a WRT310N (Broadcom Chipset BCM4785), or, as it was advertised, any brand of router? If not now, wIll updates to DD-WRT allow this?
And BillGiles and Jotin, if you have some insight, can you please post. Curious to see if you were able to get it working.
Thanks for any feedback,
