I installed Norton 360 on my eMachines Notebook a week ago. Since then I haven't been able to get online using any one of my three wireless modems (each one from a different provider), though they all work fine on my Dell Inpiron Laptop. When I initially connect the modems to the computer, they're recognised by the machine, and I'm therefore able to top-up my pre-paid credit, check my acccount balance, etc. But, as soon as I attempt to connect to the internet, I get a 'can't find modem' message. I've already tried unistalling Norton 360, but that didn't help. Any ideas anyone?
