In the Network & Sharing Center's "Change Adapter Settings," there are usually Local Area Connection (wired) and Wireless Network Connection.
For as long as I can remember, my computer (and I'm not sure why) has had Local Area Connection, Local Area Connection 2 (Network cable unplugged), Wireless Network Connection, and Wireless Network Connection 2 (Not connected)
Here's the background story. I always used Wireless connections. There's no problem with that now, I can connect fine.
I recently connected my XBOX 360 through my Dell Inspiron's port (by allowing other computers to connect through my Local Area Connection).
For the first few days it worked fine, without problems. I came home yesterday to find there was no connection through to my XBOX 360.
Here's the problem. I found that in the Network & Sharing Center's Network Connections, my Local Area Connection is nowhere to be found. My LAC2, WNC, and WNC2 are still there. I have checked my Device Manager to see if my LAC was disabled, I have also been looking around forums and such-like to find anything to help, please let me know.
