HELP! WiFi connected but cannot access internet!

[jooch]

Hi guys, I have this problem that's been giving me a headache these days... I have a Dell XPS L502x with Intel centrino n6230 in tow.
Well, the laptop was working fine and all but started to have this weird connection drops in my work now and then, I blamed the router. Then it started loosing connection in my home too, it shows that the WiFi is connected and when I hover over the WiFi icon it says "internet access" but whenever I tried to access a webpage it won't connect... I blamed the network adapter and tried reinstalling and reinstalling the drivers and changing settings but none of it worked.
It literally is driving me crazy, but before I refresh the system I wanted to see if you guys can help me out!
Thanks in advance

If you really do have internet access you should be able to ping a DNS server located somewhere outside your network. open a command prompt, Start > run > enter "cmd" and hit enter. type in "ping 8.8.8.8" if you get a response in replies you know that its technically working and connected to the internet.

I did the ping thing it said "request timed out, reply from 192.168.1.211: destination host unreachable, request timed out, request timed out"
I did a system restore and everything was working fine, I just installed office suite, light room, bittorrent and chrome, I don't know what the heck is going on and its driving me nuts! :s
