Early Saturday morning I'm surfing the net for awhile. I shut it down for about 15 minutes then get on the computer again and no internet. Cant connect and there is no internet icon to look at networks. So I go to the other computer and all is fine. Reboot the machine, reboot the modem, nothing. My computer has a built in adapter. So off to Best Buy to buy an external one. stick it in the USB port, run the software and all is good. I'm only posting this because I rarely fix computer issues myself.
