Network Problem, Dns Keeps Going

[Elspuddy]

iv got a dlink dsl-G604T adsl modem router 4 port switch, wifi point all in one job, now recently 3 of my pc's could not connect to the net, i ping a few sites and found out that the dns was the problem. now I'm stumped on what to do, iv try ed other dns ips and they all have the same problem,

[Moby-Dick]

can you set the DNS proxy on the router ?

if it's anything like one of my old d-link's you need to disable dns proxy and set the dns on the pc's manually, then disable universal plug and pray..
