Hey hate to thread jack but i figured i would post my probs as well

Got a rather new HP Gateway notebook running vista that has a really weird networking issue. Whenever I am on my home network, the computer doesn't want to identify the network. Its really weird, there are 5 computers total on this wireless network and all others work fine with this being the newest computer! Is it vista? Every time i boot the comp it sits there for like 2 minutes trying to identify the network, it never does, just ends up connected to it as an unidentified network with limited access??? I troubleshooted and noticed that the wep key for my network always resets to some 6 digit key that i have no idea about. After i go into the security settings and type in the true wep key everything works fine but only for about 1-3 hours max then the network magically becomes unidentified with limited access again??? After going through this around two times it won't even connect to the net even when i type in the correct key. Is there someone remotely fishing with my network settings???? Whenever im at school or like starbucks it connects fine with no issues at all, im online at a starbucks right now lol. I dunno been trying to fix this for the past few weeks and its driving me crazy!!! HELP!!!!!!!!!1111
