So despite reading numerous posts here about it not working, I went ahead and tried anyway. And I am now running two GS routers bridged on the same subnet using WDS and WPA. I even have an Airport Express hooked up - albeit in client mode since I don't need it to act as a repeater. First, my setup and equipment. Two WRT54GS's - one a v2.1 (the Bridge) and one a v3 (the Router). Both flashed to the 10/24/05 beta release of v23 DD-WRT. The Router is directly connected to my cable modem and hardwired to several computers in the main computer room. It has a fixed LAN IP address of 192.168.1.1. The Bridge is downstairs and hardwired to my Home Theater PC. The Bridge has a fixed LAN IP address of 126.96.36.199 (my network IP addresses are a bit screwy). The attached HTPC is also setup with a fixed IP - 192.168.1.183. The Airport Express is setup as a iTunes remote music server and a print server. It has a fixed IP of 192.168.1.180. It is running the latest firmware - version 6.2. Now for the configurations on the WRT54GS's. Note: I'm only going to mention the key (I think?) configurations - everything else is left as default. The Router: Setup/Basic Setup (1) Internet Connection Type: Automatic DHCP (1a) STP: Disable (disable for Comcast ISP) [I use Comcast] (1b) Name: Router [I'm nothing if not creative] (2) Router IP: Local-192.168.1.1; Subnet-255.255.255.0; Gateway-192.168.1.1; DNS-0.0.0.0 (3) DHCP Type: DHCP Server (4) DHCP Server: Enabled (5) Starting IP: 192.168.1.100 Wireless/Basic Settings (1) Wireless Mode: AP (2) Wireless Network Mode: Mixed [Note this also worked in G only mode, but I plan on adding in a Palm TX which has 802.11b to serve as a remote control for the HTPC]. (3) SSID: mysupersecretssid (4) Wireless channel: 11 (5) SSID broadcast: disabled (was originally enabled while setting up, but once everything was working, I disabled it). Wireless/Wireless Security (1) Security Mode: WPA Pre-Shared Key (2) WPA Algorithms: TKIP (3) WPA Shared Key: mysupersecretpasscode (4) Renewal Rate: 3600 Wireless/Advanced Settings (1) All defaults except... (2) Frame burst: enable (3) Xmit power: 100 (4) Afterburner: On Note: I got everything working without Afterburner on and then enabled it. Not sure it really does anything in WDS mode, but... Wireless/WDS (1) Wireless Mac: Single entry LAN - with the wireless MAC address of the Bridge. Make sure you use the wireless MAC address which has a different last digit than the one printed on the router. (2) Both Lazy WDS and WDS subnet disabled. I also have Port forwarding setup to allow remote access to the VNC server on the HTPC, but that's not necessary for the purposes of getting the bridge setup. The Bridge: Setup/Basic Setup (1) Internet Connection Type: Disable (1a) STP: Disable (disable for Comcast ISP) [I use Comcast] (1b) Name: Bridge [Consistency! ] (2) (2) Router IP: Local-192.168.1.50; Subnet-255.255.255.0; Gateway-192.168.1.1; DNS-0.0.0.0 (3) DHCP Type: DHCP Server (4) DHCP Server: Disable Wireless Use the same Basic, Wireless Security, Advanced Settings and WDS (just substituting the Router's Wireless MAC address in the WDS LAN entry) from above. In addition, I set up MAC filtering so that clients (my laptop and eventually the Palm TX) will connect to the Router instead of the bridge. Wireless/MAC Filter (1) Permit Only PCs listed... (2) Add the Router's Wireless MAC address to the Filter List Airport Express I use the Airport Admin Utility to configure it. I did run into some problems with the utility not being able to fully connect to the Airport. It started working after I turned off the Firewall and filtering options under the Security Tab in the Router configuration. I could have just used a direct connection between the computer and the Airport, but then I would have had to climb under the computer desk. Airport Tab (1) Wireless Mode: Join an Existing Wireless Network (Wireless Client) (2) Network Name: mysupersecretssid Under the "Wireless Security" on the Airport Tab page (1) Wireless Security: WPA2 Personal (2) Under the "Change Pre-Shared Key..." button, enter mysupersecretpasscode Internet Tab (1) Connect Using: Wireless Network (2) Configure: Manually (3) IP address: 192/168.1.180 (4) Subnet: 255.255.255.0 (5) Router: 192.168.1.1 (5) DNS servers: 192.168.1.1 [Note I haven't tried using the ethernet port on the Airport Express as a bridge. I may need to set the DNS servers to 0.0.0.0 if I do - not sure on that]. WDS Tab All greyed out since it's not used in the Client mode I have the Airport set up as. That's it... I got it setup last night and was running fine. The Bridge and HTPC disappeared from the rest of the network after I messed around with the XMit settings on the Router and monitored both the Bridge and the Router's signals using NetStumbler. I rebooted the Bridge but I was unable to test it afterward since the baby was up - at Midnight. But it was working fine this morning and as I sit here at work (working hard as you can tell), I am able to VNC into the HTPC and access the Airport Express - so it's all working. :cheering: One final note. During configuration I had both the Router and the Bridge hooked up to different computers sitting next to each other. I ran through each setup screen in parallel. Made things much easier. And I rebooted both routers after each major change (I think the more reboots the better ). Anyway, I'm happy to answer any questions. Although this setup was mostly trial and error and based on reading numerous posts here. So I'm generally clueless about the reason this works - I just know it does.
