I have two identical WiFi 802.11b networks both at home and work. I have used them both for nearly 2 years successfully until just a weeks ago when I started getting the following problem.
If I'm connected to my wireless network and then put my PowerBook to sleep and away for the night the next day when I wake my PB at work it won't connect to the office wireless network. And this is true for the reverse scenario. However, both times the new network appears in the status bar and I have a good signal. The only way to force my net connection is to log out and then back in and it works fine.
As I said I've always been able to wake the PB and immediately connect to without any intervention on my part.
I can't see other computers on the network either.
I don't remember the exact day this started but it seems to have started after the last batch of Apple updates. Not sure however.
