Dear experts, I kindly ask for your help because I will breakdown soon The situation: - A WRT54GL is used as a router and is connected to a S-DSL modem which itself got an fixed IP adress in the internet. The router's IP is 192.168.1.100 and it works as an DHCP server in our network. The IP Address Range is from 192.168.150 up to .200 - We use a file server with Windows Server 2000 which has a fixed IP 192.168.1.1. It got an SQL server running on it for a business software solution. - We (try to) use two WRT54GL as access points to get the notebooks connected to the network. These WRT got fixed IPs as 192.168.1.30 and .31 (firmware 1.25) The problem: After some hours of wonderful function the Windows 2000 Server brings a warning that there is / has been an IP conflict with the MAC address of one of the access points. Often the connection from the logged-in clients to the SQL-Bussiness-Solution is cut off and everyone hast to start again. Interesting: an old 3Com access point did not make these problems. But unlike the WRTs it got just one MAC address for LAN and WLAN. Could someone please help me? Thx a lot in advance! Best regards Marc PS: Sorry for my bad english!
