No connection-No connection available on my Asus laptop

[Bubblemonster]

A couple of days ago my laptop connected fine to wifi. But now it shows No Connection - No connection available. I've tried everything. FN-F2 (Which is my wifi key). Went into my Bios tried to figure out if something in there was wrong. I checked my network adapters, no corrupt files, and no yellow exclamation points. I even reset my laptop back to factory setting. It still says I need an ethernet cable. Any help would be appreciated.

If it is asking for an Ethernet connection, it is possible that the WiFi on the device is no longer functioning. If you can test the connection by connecting via Ethernet and that works, then I would see if you can borrow an external WiFi card (plugs in via USB) from someone and see if that works. If it works fine, I would say your internal WiFi is in need of replacing.
