I have a Vista machine which connects to the INternet using a 3 Mobile Dongle. Suddenly - and for no reasopn I can see - Ineternet Explorer says I am unable to connect, and I cannot see andy web pages. When I look at my network settings, they are flashing away quite merrily, and say there is no connection problem. I can use MSN and am receiving e-mails.

Please can somebody advise?

Thanks.

Sounds like it's a DNS problem try placing an IP address in your browser instead of a name. Domain name servers resolves names, ping a website in the cmd prompt: ping www.google.com for example get the IP address type into browser, if the website works that way it is a DNS and you should contact the dongle supplier, in your case 3 mobile. Good luck.
