Do you have a firewall that is misconfigured so as to not allow connection to the internet?  Does the same problem occur if you boot to Safe Mode with Network Support?

 

Steve

Thanks for reply.  I have tried switching off firewall and running in Safe Mode with Networking. Still the problem persists.  The laptop successfully connected through someone else's (unsecured) wireless router yesterday but still won't through mine!

To help troubleshoot this problem, on the computer that is having the problem, go to Start > Run and type cmd then click OK. In the command prompt window that opens, type ipconfig /all then hit the enter key. Write down the output from this command or select it and save it to a txt file, then copy this output into a reply to this message.

Thanks Steve.  I did that and here is the result:

Is there a reason you have ip v6 installed?  If not, go into Network Connections and remove it and see if that fixes the problem.

Thanks Steve  I've done that but it makes no difference.  Weird that I can use the router to access the local network but it won't display any webpages in any browser although the computer tells me that the signal from the hub is excellent.  My virus software tries to update its database but gives up eventually as well.  The desktop accesses the internet through the hub with no problem.

TRy this:  Open Internet Explorer, click on Tools > Internet Options, then click on the Connectionson  tab.  Make sure the box is checked next to Never Dial a Connection then click on the LAN Settings button and make sure none of the boxes have check marks in front of them.  Let us know if this helps.

Steve,  I compared the settings on my desktop with the laptop to see if there are any differences. I found that on the "Advanced TCP/IP Settings" tab a default gateway ip was set on the laptop and not on the desktop.  I removed it and it now works fine.  I have no idea what all this means but I seem to have resolved the problem.  Thanks for your help,  Peter

Good find!  Congratulations on solving the problem.  All it takes is one wrong setting somewhere and you found it.  I would never have guessed, mainly because those settings would rarely get changed except by direct user intervention.   Happy surfing!
