...a long shot, since you have other laptops and would probably know better - I suppose the wireless on/off switch on the edge of the laptop is switched on? ....I only suggest this because I've overlooked it myself when it's somehow got knocked to the off position and I've tried all sorts of other diagnostics before realising !
Have you checked that the wireless encryption settings on the laptop match those in the router?
You could also check whether a hard wired RJ45 connection from the router to the laptop gets you online - if it does, then the basic configuration should be correct and I can't think of anything other than encryption mis-match and wireless network access password that would stop you displaying web pages. ....and of course you'd get an error message of some sort if there was any password issue.
...after that, I'm afraid it's over to someone who knows more than I !
checked em all my friend..........i have even turned off the wirless on the ltop and installed a vodafone dongle to connect in a different way.....it does exactly the same.....connect to my router immediately but refuses to display any web pages
....by "checked 'em all" did you mean you've also tried a hard wired network connection? I ask, as this would at least tell you whether it's a general network set-up issue or a wireless one.
What Internet Security apps are you using? I bought a Vaio this Christmas and it came with all sorts of stuff pre-installed and just waiting to auto-leap into action. This included McAfee, which I've not used before, and which attempted to set up various layers of security that I didn't want. When you disabled the firewall, did you ensure that Windows and 3rd party firewall and security options were all covered ? .....it does sound like the problem lies there somewhere
