Windows braindead wireless

I admit it, the new Toshiba is way nicer to use than my pokey old Thinkpad. But one thing bugs me a lot. We have a wireless network, and every once in a while, I lose connection to it. This is in the exact same place as where I use the Thinkpad running OpenBSD, and it never has this problem.

When Windows loses the connection, it won't reconnect automatically because the network isn't secure. This is a Good Thing, of course, but still highly irritating to lose all the ssh connections at once. Thank god for screen . The question is, why does the connection go away?
