I use Windows XP Pro SP2 , no hardware modifications.
As i told you ... the problem is at windows level somewhere ..

When i start the Intel Pro/Wireless 2200 card, and the MSI PCMCIA wireless card is working everything related to wireless.. services, connections, network configurations windows... Everything frezees!!!
When i use only the MSI PCMCIA or Intel wireless card everything is OK!!
But both NO!!!
Any help?, any workaround?
