IP Conflict

Discussion in 'Cisco/Linksys Wireless Routers' started by Lazarus, Aug 16, 2005.

    I have 2 WRT54G routers. One is configured as a gateway and has a cable modem connected to it. The other is configured as router and sits on another floor of the building. I get an IP Conflict once in a while and everythings quits. I thought I had read that the router which is configured as a router should have the DHCP Server turned off so the gateway router will handle the IP distributions. However, when I turned it off I lost everything from both routhers. Can anyone Help!

    Do the DHCP server ranges overlap on both WRT54G routers? It is usually recommended that the DHCP server be turned off on the second WRT54G and it be connected by a LAN port to a LAn port on the Gateway. What firmware are you using. The recommndation is for stock firmware.

    The starting address on both routers are the same: 192.168.1.100 so I guess this would be overlapping? I have the latest firmware, 4.00.7 so I know that isn't a problem. Would changing the starting address for the second router help? Thanks

    Yes it would. I would change the setting of the starting address to be as futher away as the number of clients you allow to access the routers. For example if you allow twenty five clients on each router, set the second router to be 192.168.1.126 or 192.168.1.74. By setting the same starting addess range, you almost guarantee a conflict periodicaly.

    Thanks Howard,

    Perhaps this will fix the problems I am having.
