I tried this, but it didn't work. I fear the location of my gateway router that hosts the wireless is just in a bad location. My home has the cable Internet coming into the basement and terminates at the cablemodem, which resides in a wiring closet underneath the staircase.
From there, I branch out using a stock WRT54G2 Linksys/Cisco. The LAN ports afford network branching to the basement and the 1st and 2nd floors. There are then Ethernet switches on those floors to provide tributary networking.
I thought about buying a WRT54GL, which is a reissue of the original WRT54G running Linux on the Broadcom chipset, but I am not sure how to configure this into the network on the first floor. The gateway router in the basement has a local IP of 192.168.1.1, and the LAN pool is 192.168.1.100 with 50 IPs.
I tried changing the local IP of the WRT54GL to 192.168.1.2 (to differentiate from the gateway router's 192.168.1.1) but it disallows me from running DHCP on the second router using anything but the 192.168.1.x subnet.
Anyone know how I should be configuring this second router in the network?
