I can connect to a wireless network, but I cannot use any applications such as web browsers, or updating virus definitions, etc. When I connect wired to the same network I can use the internet freely and use applications with ease. I have tried this with 2 different networks now, and it works the same way. I don't think it's my firewall because even if I disable it, I still have the same problems when trying to connect wireless. Please help me figure out how to fix this. Thank you.
