I've got an Inspiron 8600, Windows XP Home, SP1.

I disconnected from my wireless network connection by pressing Fn F2, and now I can't seem to get the signal back.  This is the first time I've done this. (I just wanted to see how the Fn F2 worked.  I've been connecting to my wireless network just fine for nearly 9 months.)

My network connections window has Wireless Network Connection listed, but as unavailable.

A right click properties shows that I have "Use Windows to configure my wireless network settings" enabled (as it always has been), but there are no available networks listed.  The network is listed in "Preferred networks", though.

I have an Inspiron 6000 XP Home, SP2 running right next to the 8600, and it is connected to the wireless network (strong signal, too) just fine.

What have I done?

Thanks,
