MBP Airport - no WiFi after update

[B74A]

This morning, Software Update came up and said there was an update for my 2008 MBP, this time something with the CPU or something. Upon restarting, gray screen, fan at high speed, do not interrupt it while doing so etc.

This update apparently for older (2008) Macs to be able to use a new type of charger that has come out. Nothing I heard off before?

When I did the update, it did come up with that gray screen as advertised, and the progress bar ran for just about one second, then it booted again. Everything went normal, but upon start I noticed the Airport had wireless turned off. In fact, it says: "Airport: Off". I clicked On, but nothing happened. After reboot, I cannot manage to turn it on, not from the System Preferences screen either.

I have now plugged in a network cable straight from the router, since the WiFi does not work, and with the cable attached, no problem.

But I want my wireless internet/network back!

Any ideas ?

Reset SMC, NVRAM etc.?

How to do that please?

Maybe it needs some kind of "reset", but the only one I know of is shut down and restart - which does not help. Maybe I should hold down the power button and force-quit the whole Mac.

But tell me how to "reset SMC" pls

By the way, this is status now:

It works again now!

I closed all apps running, then held down the power button to force-quit the Macbook Pro. After restarting it, the Airport is back up and running. I have no idea why, but it works:
