On a Windows Vista machine when connecting to broadband using wifi I see the connection OK, and things like Skype work fine wirelessly, but all browsers give page not found errors. Have tried IE, Firefox & Chrome.

I suspect its something to do with my Norton Antivirus but Skype is working fine.

Also the cabled connection to broadband works fine for all web connections.

Any ideas?

Does the browser always give an error or only most of the time? –  Ludwig Weinzierl Jul 15 '09 at 23:21
    
While you are wireless, run "cmd" and type "ping www.google.com" (without the quotes). Does it say "request timed out" or "reply from [some number]"? –  AdamB Jul 15 '09 at 23:40
    
@Ludwig the error is all of the time when wireless. @AdamB I'll give that a try, its my brothers laptop and he's in Ireland asleep now. Thanks –  MadMurf Jul 15 '09 at 23:47

This sounds like a firewall issue.
Skype is known to work through partly firewalled paths.

While Skype is working, can you do a ping to say, www.google.com?

Most likely a DNS issue. Does http://74.125.67.100 take you to google?

Would this make a difference on the same machine between wireless & wired connection to the broadband router? –  MadMurf Jul 15 '09 at 23:48
    
There should be no difference in internet access from a Wireless connection to a Wired connection, in regards to your DNS. –  Charlls Jul 16 '09 at 1:00
    
Thats what I thought. It works fine when connected by wire to the router, its only when wireless that the browers don't connect but skype still does. –  MadMurf Jul 16 '09 at 2:12
    
So probably not a DNS issue. –  MadMurf Jul 16 '09 at 2:13
    
Why can't it be? If your router or AP gives a different DNS server depending on wired or wireless, that could happen. It could also be an issue with binding to that adapter, but I have no idea how to check that or fix it. Just mentioning it to see if that can happen. –  Joshua Nurczyk Jul 16 '09 at 20:18

Try checking your router for the MTU value. Set it to a value of round about 1400 and see if that resolves your problem. Some ISP's routers drop packets if they're too big rather than fragmenting them.
