1) Right click on "Internet Explorer" icon --->click on "Properties" ---> Click on "Connections" tab--> Click on LAN settings button. In that window uncheck all the options, if you notice any option selected--->Click on OK---> Click on OK.
If the problem still exists, go to step 2.
2) Make sure that IP address and DNS server was set to obtain the address automatically.
Click on Start --> In search bar type ncpa.cpl and press "Enter".
Right click on your Network icon ---> Select "Properties" ---> scroll down and double click on "Internet Protocol[TCP/IP]" . Make sure that "Obtain IP address automatically" and "Obtain DNS server address automatically" options are selected.
3) Click on Start --> In search bar type devmgmt.msc and press "Enter". Type this command
ipconfig /all
and press enter. Make sure that IP Address, Subnet Mask, Default Gateway and DNS Servers are having addresses.
4) Check your firewall (try to turn it off to see if it helps).
5) Try to desactivate your antivirus to see if it helps. If you have McAfee, uninstall and reinstall it.
Note from Shahab1210 : Click on Start --> In search bar type ncpa.cpl and press "Enter". Right click on your Network icon ---> Select "Properties" ---> scroll down and double click on "Internet Protocol [TCP/IP]", set your "Preferred DNS Server" to 8.8.8.8 (Google) or 4.2.2.4 (OpenDNS)
After doing 4 steps above (if it doesn't work) do this :
Click on Start --> In search bar type ncpa.cpl and press "Enter".
Right click on your Network icon ---> Select "Properties" ---> scroll down
and double click on "Internet Protocol[TCP/IP]", set your "Preferred DNS Server" to 4.2.2.4
When it finished, you should reconnect, the changes will be applied after that ;)

I just spent 2 days figuring out the same problem, but with a different cause and I'd thought I would post here so others won't waste so much time!
My problem was caused by an automatic McAfee Update on 8/18/12.
Search their site for the details, but the solution was to uninstall and reinstall their security suite.
I never would have thought of that. It was working on my PC, but not on my phone, though I have McAfee on both. I'm kind of hesitant to reconnect it now. Thank you! You saved my sanity!
OMG THANK YOU!! I tried everything else in vain! every other computer in the house had internet access but mine and while uninstalling mcafee I gained internet access again. now I can resume watching dragonball z
