The card is perfectly fonctionnelle.Mais installed on the PCI-EXPRESS slot 4 of a server motherboard and Windows XP Professional liaison with the Linksys X3500-EW router is instable.Une after pairing the card passes all tests Intel without problem.But it takes each system restart go into the device manager to activate the drivers provided by Intel liaison.Les therefore suitable pas.Par against Windows 7 users report no problems.
