I can't connect eiter

Hello,
I have an IBM Think Pad and was connected this morning with no problem. I moved locations in the house and notice I had lost connection. I went to re-connect and notice that the icon was gone (view wireless networks) I went into control panel and scanned for wireless networks and it shows none. I am on a desktop PC now and I am able to view many, just like I could with my laptop this morning. Any ideas? I would really appreciate any help. Thanks
