Sony Vaio Wireless

[TechSupp]

Got a Sony Vaio laptop with Vista on it which I have just restored toits original state due to it not connecting to the internet and it still wont unless I stick a Lan cable in. It finds the wireless network, picks up the IP form DHCP connects, shows goo signal strength etc but wont connect to the internet. Tried pinging the router with the LAN cable and it returns OK but pinging the router via wireless gives a no reply from 192.168.0.21 which is the PC itself rather than no reply from the router address! (router is 192.168.0.1).
Any ideas where to go next, thought a restore of the c: drive would sort any issue but alas no. Its as though wireless internet is being blocked over wireless but not LAN cable. No AV at moment, firewall off etc.

Try either a different/updated driver or a new wireless card.

Got it sorted, was a Vista driver issue with WEP AES security, updated it fully and got it to look for an updated driver, it found one and all was well
