no wireless after yesterday's update on mac 10.6.8

[katties]

After the update yesterday I can't connect to the wireless. Wireless is working fine on other devices (Windows pc, iphone etc.).
I tried the basic solutions, turning airport on/off, changing networks, restarting mac. Is there any simple solution why it happened?
I am thinking of
1) restoring mac to the backup from the time machine
2) restoring it to factory settings?... would it change anything?..
Any comments greatly appreciated. Btw, I am not an advanced user.

What kind of update did you download?

I believe it was: Security Update 2012-002 (Snow Leopard)

I have also downloaded it again (no harm now, isn't) and run it on the mac again, just in case something went wrong the first time (I postponed the update)

Did you reboot your AP/Router?

Will it change anything? As I say, router is working fine, succesfully sending signal to other devices.

I am willing to try though, but actually when should I do it - I mean, with my mac on or off?

Shouldn't matter, but do it with your Mac off. Reboot the router, then turn on the Mac.

Ok it really worked! Thing is, I was a real non-believer. Thank you I really owe you!

No problem, you're welcome.

Your router was not negotiating new connections, but the devices (PC, iPhone, etc) that had already made a connection were still working. It happens occasionally, and since rebooting a router is usually pretty easy, it is often recommended just in case.

Glad to hear you got it working!
