The IP address for a belkin router is 192.168.2.1 (as you said sky). Think you have the same router as me :P
Try unplugging the router from the mains supply for a few mins, then plug it back in and try access the page. If that doesnt work, and all the router likes are on (accept mayb the LAN one for your computer) then its a problem with the connection between the router and your PC (obviously :P ).
Also, try access the routers homepage on another computer on your network/router.
