I have a friend with Verizon DSL and the Westtell Router with Wireless access (DHCP enabled). There are 2 Sony Vaio laptops in the house, with different configurations. Both were working fine until the problem laptop installed an upgrade to Norton Internet Security. The problem laptop will connect to the network, with strong signal strength, and I can ping the router. However, the laptop will not browse on the internet. At first I thought this was an issue with Norton, and started configuration steps. However, even with personal firewall disabled, security disabled, it still will not browse in Internet Explorer. The other sony vaio still works fine. I can bring the laptop to my office and it browses just fine using my wireless here. What am I missing? Is it a problem with Norton or something else?
