This time its in my own home. I have a Netgear wireless router and a Netgear USB adapter that receives the signal upstairs to my desktop. After I brought my desktop home and set it up, however, I can't access the internet. The adapter connects to the network, but I can't connect to the internet. I have both another PC that connects through Ethernet and this laptop that connects wireless through the router, and both still get internet. I've done a few things I've considered common sense, like disabling firewall and ensuring that the wireless network is default, but still no luck. There are also a few odd things:
There is no local area connection listed under the network connections, only the wireless connection. This is odd to me because I thought that before it always listed one even if it wasn't in use, like right now on the laptop theres a local area connection 2 listed even though its using wireless network connection.
Also, though there is no local area connection, I still see everyone's shared files under my network places from the lan. Even after turning the computer off, restarting it, and refreshing it, all the files are still there, obviously inaccessible. Though there are no additional PCs listed on workgroup computers.
At this point, I'm stumped and have no idea what to do. And with the desktop being my main gaming rig and L4D2 demo releasing soon, I need to get this fixed. Any ideas are greatly, greatly appreciated.
