i have a dell inspiron desktop. it will not connect to the internet though it shows that i have a connection. my son has a laptop and he can get on the internet. i can also connect to the internet with my iPhone and iPad. when i open up IE and firefox the page is blank. i can type in google in the search bat in the corner and google comes up. i can do a search in google and as soon as i click a link it says that i am not connected anymore. i can also click any of the bookmarks on the toolbar and they sometimes work.

i have one firewall, it is on. have tried turning it off and that does not work. i can't scan for viruses cause for some reason my virus scanner is logged out and it won't let me log back in because i have no internet connection

Try this.
1. Plug your internet cable.
2. Check your windows update
3. Go to the optional
4. Look for your wireless upgrade.

Let's say i have wifiV1 currently there should be an upgrade wifiV2 in the optional and then update it after that restart if you are done tell me.
