    Hi, I'm new here and have a problem that hopefully you can help me solve. I recently purchased a new Dell computer which is running Windows 7. It works great except I cannot get it to connect to the internet. I am one of 3 computers running in my house and mine is not the one with the direct (ethernet) connection. My old computer (which I am using now) connects to the wireless router fine (it uses XP) and so do the other computers in the house (also XP). The new computer has a wireless card in it and it detects the network (the name 2WIRE088 shows up in the list of available connections). I have typed in the encryption code to gain access to the network, it says it's trying to connect, and ultimately says it cannot connect to the network. The wireless indicator on the router box very rarely comes on when the computer is turned on. I have tried resetting my IP address, I unplugged the router and plugged it back in, I tried all the troubleshooting I could, nothing helped. I called the Dell tech support which did not help at all. Does anyone know how to fix this?? PLEASE help if you do! Thanks!

    Make sure you have the latest wireless driver from Dell's web site.

    Are you able to connect successfully by ethernet? If yes ...

    Disable encryption and MAC Address filtering on the router and try to connect. If successful you can probably re-enable encryption and reconnect.

    If you cannot connect by ethernet then uninstall or properly configure your firewall or security suite.
