I have tried to link two WRT54GS together to extend the range. After 3 nights of guessing, I got some progress. I am totally unhappy on the WDS part of the Santori 4 firmware. Sveasoft also closed support forum which makes things even worse. The doc site (docs.sveasoft.com) is totally out of date and points you do closed links on their forum. Here is what I did: Router 1 is on DSL with WDS in lan mode and MAC address of router 2. Firewall and loopback is off. Router 2 has diffrent range of DHCP and WDS has MAC address of router 1 and in lan mode. Firewall and loopback is off. Gateway is point to the IP address of router 1. Both rounter has same infomation on SSID, channel and WEP. After rebooting both routers, computers on router 2 can ping router 1 gateway and can log into router1. I can also ping the gateway of my DSL, but not the DNS. I can see computers on router 1 and access their disks. BUT, COMPUTER ON ROUTER 2 HAS NO INTERNET ACCESS!! OK, I thought it might be the problem of the DHCP server of router 2. So I turn off the DHCP on it thus make router 2 a repeater. It works great! Err, just for a while After trying to move the router 2 around the house which means I have to reboot it several times, something bad happens. Whenever router 2 is on, the computers around it immediately dropped their IP address from router 1 and try to get IP addr from router 2, which has DHCP off. So they stuck with no IP address. I am not sure even with some documentation and help from Sveasoft this setup should work. It looks like the firmware is not stable. This is the reason I do not want to pay $20 for newer version until I can get it working. What Sveasoft should do is to have the Santori forum open for everyone for free. Once everyone is happy with the older firmware, people like me is more likely to pay up for new versions. That's bad marketing from Sveasoft!
