The AG-320 Wireless PCI Adapter connects your desktop to three wireless standard networks (A, B and G). To avoid interference, you can use auto frequency band selection or switch to IEEE 802.11a connection mode. Unlike IEEE 802.11b/g networks which use the 2.4GHz band, IEEE 802.11a uses the 5GHz frequency range specifically for high-speed transmission. In addition, with IEEE 802.11a, you don't have to worry about interference from Bluetooth systems or home appliances (such as microwave ovens and cordless phones).
