Laptop wrongly thinks there are "no connections available"
Until today, the wife's laptop had been connecting flawlessly to the wireless router and also showing multiple SSIDs of our neighbors. Then this morning, nothing. Did some fiddling and enabling/disabling the wireless adapter and then it worked for a short time. Now nothing again. It just says "no connections available" on the tray icon. At one point I was able to see our SSID, but without being able to connect to it. I'm not an expert, but this seems like a hardware issue, although I hope not.
Background: (1) the laptop connects to the internet with a wired connection (I'm using that connection right now); (2) my macbook, printer, and apple tv all connect fine to the wireless network; (3) the laptop shows "no connections available" but the macbook still shows several of the neighbors' SSIDs.
For these reasons, I conclude it must be a problem with the wireless adapter or wireless settings--hopefully not broken hardware--rather than a problem with the router.
I have searched the internet and sevenforums and tried several things for the last couple hours:
(1) restarting the router (multiple times)
(2) restarting the computer (multiple times)
(3) running the troubleshooting on windows
(4) turning off and on the wireless with the physical switch on the keyboard
(5) restarting the WLAN configuration service
(6) turing off IPv6 (I've now turned it back on)
I tried to do a system restore, but somehow that turned off. (There seems to be some problems with the settings there since when I tried to change the disc allocation for the restore, I got an error message)
Also, the laptop runs quite hot. I guess I'm wondering if that could have contributed to a hardware failure.
The adapter is an intel wifi link 5100 AGN. According to the device manager, it is working properly and does not need a new driver.
The ipconfig info is here:

I have no idea what these "tunnel" adapters are.
I'm hoping to be able to fix these problems with the help of the experts here. But I would like to know if this problem could be fixed by buying an add-on usb adapter or if it is likely that there is something in the settings that would continue to malfunction.
I would most appreciate help on this, as we cannot afford a new laptop right now!
Thanks!
