Recently I my WiFi just stopped. This is on an HP ProBook which until recently would have WiFi for a few hours, or a couple of days, then the WiFi would stop. But restarting the computer brought back the WiFi. Now restarting the computer does not bring back WiFi. Pleases look at the below output and tell me what you think the problem could be.

$ sudo lshw
