Hi guys ,

My problem is the following:
Have a Toshiba a215-5818 with Vista Home Premium and a Atheros Ar5007EG onboard wireless adapter.
The thing is that with my wireless adapter i can connect with no problems to a wireless network with no security enabled. But when i tried to connect to a wireless network with WEP or WPA activated its imposible.
It can't connect tried everything, updated the driver, installed the Service Pack, send mails to Toshiba, Microsoft and Atheros and they couldnt help me. Still having problems
If I change the windows for XP it works perfectly well.
So need to know if there is any fix for these , any bug known or something.

I hope someone could help me.
Thanks a lot
