I have a DSL modem provided to me by ATT yahoo DSL. Its a weston brand connected to a linksys router with 4 ethernet ports and wireless.
I have the linksys router set to a specified DNS 192.168.0.21 which is a windows machine. every so often the ip address for the DNS on the router changes to 192.168.1.254 which is the gateway ip address for the ATT modem.
Any ideas what might be causing this?
thanks in advance
