I need some help. We have a wireless network set up, but my laptop does not seem to be able to recognize and automatically connect to it upon startup. Everytime the computer goes to sleep, it disconnects from the network. Then upon resuming it says that none of my preferred networks are available and gives me a list including my network. The thing is, I checked in my system preferences and my network is listed in the preferred network. Any help would be greatly appreciated. It's not a huge deal, but it's a bit annoying to have to manually connect every time I come back to my computer.
