Re: Buffalo WBMR-G125 router help
The issue is probably that you already have a router, the BT Voyager 190. So, you are cascading two routers. Since the user manual doesn't seem to be readily available for that ADSL router, you'll have to see if AOL can tell you how to configure it into bridge mode so you can use a real router. Personally, I'd just get a real ISP, and lose AOL.
You can also keep the routing function of the existing router and configure your wireless router as a switch/AP.
Connecting two (or more) SOHO broadband routers together.
Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.
Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.
Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.
Disable the DHCP server in the secondary router.
Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.
Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!
This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).
