I have this weird issue with HP Pavilion dv6700 Notebook, running Vista Home Premium. When a user is trying to get onto WiFi in the office, she sees the network, connects to it, but can't access the Internet (everyone else can). It's a WAP security enabled network.
I updated the wireless driver, as well as uninstalled the 3rd party WiFi management software. I am not really sure why it happens. And she can connect to the WiFi everywhere else, it's just in the office, she can't.
I should also mention, we updated the local hardware firewall and WiFi points. I tried changing the key, reverting back to the old key (she had a profile saved), removing the profile from her laptop and re-joining to no luck.
