can not get on an internet browser

I have an acer laptop and a linksys wireless router.. With this laptop i can get on aol instant messenger but not on any web pages... I use internet explorer.. but thinking it was a problem with my provider i tried to get on msn and while setting it up it said i was not connected despite being on aim. I sat on the phone for a couple hours with linksys trying to fix the problem but they finally concluded that the problem was not w/ the router considering i have another computer running off the router fine. I do not have my firewalls on so i dont think thats a problem and besides that.. i can not get on webpages through my wireless or even when i am directly hooked up to the modem. Its been almost a year since the last time i was able to get on the internet. Can you help?

 

i have windows xp and its service pack 2. i just went into safe mode.. ie did not work there either BUT when i went under netwerk connections it did not have any icons for me to make sure it was connected either so i dont know if that was why it did not work or just because my comp wont work......?

 

ok so i did what you said.. i typed in the netsh winsock reset catalog.. and it said it was reset.. on the next prompt i typed in netsh int ip reset reset.log and it just put up another prompt.. it did not say it was reset or anything... but ok so then i restarted comp anyway and it did not work.

 

It totally works in safe mode!!!! thats so exciting, there is hope!!... do you know what i should do now?

 

Thanks... i did not have to go through the whole misconfig thing... i opened my computer and thought wow! i am so sick of seeing this pop up saying i had to update my ezantivirus.. so i took it off and restarted to apply that change and then my internet worked.. easy as that... THANK YOU SO MUCH... i can FINALLY use this computer now!
