A child got to my laptop and somehow turned it off. When I got it back on again and rebooted, my laptop no longer recognized wi-fi signals. I have tried to figure it out, and have re-started it, but nothing. There are always wi-fi signals around my house, even when my own is not functional (but it should have been, in any case). Anyone offer any suggestions? I will be able to try them this evening. And, I appreciate any help anyone can offer.
