Can't get my MacBook to default to my home network
I just switched from BellSouth (AT&T) to Comcast. I'm using their wireless router instead of my Airport. Whenever I close the laptop and reopen, it defaults to a neighbor's network, not the new Comcast router.
How can I make the new Comcast network the default one so I don't have to manually change it each and every time I open the laptop?
Thanks.
MacBook, Mac OS X (10.5.8), 1 GB Memory
