I have a PowerBookG4 (soon to be a new MBP) running 10.4.11
Often when I need to connect to a wifi network, the one netwok I need does not appear in the list. I can pick up 5 other networks (usually all password protected), but the one I need is not in the list. It is almost as if any previously joined network is invisible. My iPhone will pick it up and join no problem, and also everyone else's macs in the room (sometimes 4 or 5 friends will be around, all with no probs).
This happens in my own house on my own network, and has happened at at least 4 friends houses where I can't get their network to appear in the list. I can get by with my iPhone sometimes, but I need to use Flash based websites sometimes and it is frustrating to not be able to connect on my mac.
I have tried rebooting, and making everyone else get off the network and letting me join first, but these do not work. Then magically, the next time I go around there I have no problems at all. This has been happening for a few months and quite regularly.
Please advise any suggestions.
-I have also tried repairing disk permissions, and creating a new account and logging in. Same problem.
