Home Forums Peripherals & Multimedia Peripherals laptop hookup to computer

I have the same iMac that you do. I just looked under the Wi-Fi symbol and the list of networks only appear for less than 2 seconds. To view them again, I have to switch Wi-Fi off and then on again. Is there a way for that list to remain until I can see the network I need? My Son will be here later today so maybe he will know something.
In case he doesn't, perhaps you know?
Thanks ryck,
