My parents have a Macbook and a wireless network. Rather than using their network, which I have setup to use WPA-PSK, the MacBook keeps jumping on the neighbor's wireless, which is named Linksys and is wide open. It does this any time the computer is woken up or rebooted and often switches on it's own. I've tried creating a new network profile and setting their home network as the preferred network, but the other network keeps popping in, even if I delete it from the profile.
Any ideas on how to have it ignore the Linksys or force it to their wireless?
