Purchased one to replace a Linksys USB adapter that was causing problems. This is a great device. It worked so well I've replaced other Linksys PCI adapters that were okay, but not great. I now have 3 of the Belkins running and haven't heard a peep from them since.Signal stregth is much better that the Linksys PCI adapters could provide, even with high-gain antennas.Be sure to upgrade the firmware for WPA and improved reliability.
