Windows 7 - Internet Doesn't Work On Laptop

Internet doesn't work on my laptop. after getting some worms that prevented me to open any programs, i did a recover from previous back up. but since then my internet doesn't work (with or without cable). wirelessly: my laptop says im connected to the router, but it says that i have no connection to internet. sometimes it says that i m connected to internet but even so when i try to open my browsers (ieplorer or firefox), it just says "unable to connect"With wire: when i trie to connect via a cable directly to the modem, it does the same thing, it says iam connected to the modem but i have limited access, and the browsers say that it can't open internet.i am using windows 7, have a dell computer and a belkin N1 wireless router, and using cable.i tried to restore the winsock using the netsh command, i used winsockxpfix, i used lspfix, i deleted my norton virus program, i reset my router to default, i deleted my cache-cookie-history from the browser, i think my driver are up to date, i check my manager device (they all work), nothing worked.

when i type the command ipconfig, it gives me:

ipv4 adress: 192.168.2.2
subnet mask: 255.255.255.0
default gateway: 192.168.2.1

when i type the "ping yahoo.com" i get:

4 received, 4 sent, 0 lost

my computer works fine and i can go online. i use wire for my computer and try the same wire to my laptop but not working. i tries another cable throught the router but still nothing.
