I have a Apple iMac with an airport card... When I switch the iMac on it can't find my wireless network (WPA-PSK, channel 7, no SSID broadcast, mixed b/g network). But if I reset my router the iMac can see the network fine and gets very good signal strength (as in 90%~). Does anyone know why I am having to reset (as in power off/on) my router to get the iMac on the wireless each time I reset? Is it something to do with the iMac not storing the session password?
