Are you having trouble getting your wireless networking to work? Well, good luck with that. It can be difficult. Here, I provide you with one tip that you will not find in most troubleshooting documents but that is absolutely essential. Thisw may be the thing you need to do to make your wireless connection work. Or maybe not. But it is worth a try.
Turn it on. Many laptops have a way to turn your wireless card off and on. Sometimes it is one of those Fn key thingies. Often it is the Fn (function) key together with the F2 button.
On my daughter’s computer, which is a hand me down HP Pavilion, it is a button in and of itself in the upper right corner of the physical console. It is a simple off/on switch.
This is not a system level issue. Windows, Linux, whatever, has nothing to do with this. If your wireless card is “off” then it is simply not there. It must be turned on to work.
In Linux, there is a thingie that is linked to the physical wireless card on installation or upgrade of your system, and this thingie persists if the wireless card is turned off at the switch. This makes it look like it si there, yet it at the same time is strangely not there.
I hope this helps someone. Hey, this might be one of those posts that you should digg up, for the benefit of humankind and all.
