I went to sleep last night with my laptop on listening to a radio show online. I then woke up and the internet was disconnected. I opened device manager and there doesn't seem to be anything representing the wireless adapter, only the gigabit LAN connector. There was a windows update installation that occured last night, but I already tried doing system restore and there is still nothing showing up.

Re: The wireless adapter seems to have disappeared.
Hey, heres a list of things to try and the things that could be your problem.
check in control panel, system, device manager see if you see the wireless adapter is in there or if there is any tags with unknown device if there is drivers will need reinstalled, that would be your problem if update caused it.
other things to try is check the side of the laptop for the wireless on / off button or switch to double check the the wireless is turned on, there should be a light if it is.
if there is no meantion of wireless device, and you have tried to turn it on from the switch then its a faulty adapter..

I think you have answered your own problem, your wireless has possibly been zapped. To test your ethernet adapter on your laptop connect it to a network hub, check the hub and see if you have a link light on the hub and or laptop.. To test your wireless router, connect it to a known working computer with a network card and check the router configuration, using the browser, if you cannot access it then its zapped.
