I asked this quite a while ago, but no one seems to know what's wrong. I'll try again. Here goes: I have a network of Macs at home, both wired and wireless. When one of the laptops have been in sleep mode, it takes forever to 'find' the network. Why? Sometimes you can see the symbols of the other computers in Finder (shown as generic PC's) - in some cases they won't show at all. If you hit cmd-K, nothing happens. It can take up to 30 minutes before you can access other computers on the network. This is unacceptable. One laptop is a MacBook Pro with Mac OS X 10.6 and the other one is a MacBook Air with Mac OS X 10.7 Please help! I need this fixed! It would be interesting to know if you guys can access other computers immediately after sleep mode or if you have to wait, like I have to.
