Nokia 5530 WLAN, Local okay, remote Not

[shoaibi]

I have just bought a nokia 5530, connected to to my home wlan (no security), now problem is i can browse all lan system, even the router but i can't browse any internet. Whenever i open any site i get a "time out" while on my laptops (which are connected to same wlan) everything works just perfectly, even on my iphone.

I also tried a hard reset but no use. Any ideas?
