Windoze wireless settings

[ALE52]

Ok, here's what's happening. I set up a wireless connection to a Linksys wireless router and am using the built-in Windoze wireless software. The user opens it, checks for a wireless network, finds it, & clicks "connect". Because it is set up WEP it Windoze naturally asks for the passphrase, which my friend gives and connection completed.

What happens next is when the computer is rebooted the next day [they shut down each night] the process is repeated. Can someone please tell me how to make the Windoze wireless 'remember' the passphrase.

Thanks a lot.
