Jerry began having Wi-Fi issues after updating drivers from HP. Leo suggests looking in the system tray to see if there's a red "x." If there is, then he'll know the problem is a connection. He should go through the settings, update his password, and make sure it's in Ad Hoc mode, not infrastructure. Right click on the tray icon and select "Properties." That'll take him to settings.
Another option is to roll back to the old drivers. Jerry can also go into the system BIOS and make sure Wi-Fi wasn't disabled there.
Leo also says that there's a keystroke that will disable Wi-Fi on a laptop. It may have been caused by that. Jerry should check to see what his function key is for that.
