damned security update--help?

[leftofthedial]

I just did software update, the new security update in particular.

Now, whenever my PowerBook G4 goes to sleep, or if I close the screen, the computer can no longer see my wireless network (or indeed any network it seems). When I restart, presto, my wireless network is back, although I still have to reconnect to it. This works fine until the computer goes to sleep, then it's lost again and I have to restart.

Pain in the ass. I had a series of three or four software updates last spring that caused me to have to reconfigure my internet and network connections each time.

I'm truly and fully pissed off.

Can anyone suggest something that could cause my wireless network to vanish whenever my laptop goes to sleep?

1. Have you tried turning your airport card off, then on again using that airport menu?

No other ideas at the moment. No idea why, either.

2. I've powered the card up and down, restarted the laptop numerous times

deleted and reinstalled the wireless network, power-cycled the airport base station . . .


I found a forum discussion in which one guy fixed a similar problem from an update last month by a complete back-up, rebuild and restore of his entire system. He then turned off some of the features of the update before updating. I don't know how to do that. I took him 4 hours and he's a sys admin. Last time I rebuilt the system on my PowerBook it took several days and many upgrades and I lost much stuff.

Another fixed a similar problem with some system preferences network configuration sleight-of-hand, but I've already tried that with no effect.
