Until Snow Leopard, my Macs easily logged on to my Aiport wifi network, more or less instantly on awakening from sleep. Since upgrading to Snow Leopard, log on always takes 5 or more seconds (it appears to be searching for networks—there is only one available in my rural home.) Sometimes, it fails to log on at all and I have to find my one and only network from the menu bar. This is not fatal but it is annoying. What has changed with OS 10.6?
