WLAN issues! Need urgent help

[144]

Router: D-Link DIR-635
LAN : 2 PCs
WLAN : 1 DELL XPS and DELL Vostro
Browsers: Internet Explorer 7, Firefox 3, Safari, Chrome
Problem occurred randomly
All systems are on Windows Vista (PCs with Vista Ultimate, and Laptops with Home Premium)
The Internet is working on LAN, but on WLAN only certain websites are accessible. Have reset the router to Factory Settings, but the problem persists.
What can I do to diagnose the fault? How can it be remedied?

i think u need to set the DNS in ur router manually or in the TCP/IP of the Wireless Network Connection in the Control Panel

Paroh, Thanks a lot.
As you have suggested, I had set to a manual DNS while traveling away. It didn't even cross my mind, since it was there in both the laptops.

Once again "Thanks" a lot.
