Atheros-based Belkin adapter

Connecting the Atheros-based Belkin adapter to either of the Broadcom-based routers we tested produced solid results -- in the 70M- to 90M-bps range... Using the Broadcom-based client adapters with the Belkin router was another story, unfortunately. We saw poor performance -- less than 20M bps at short distances -- despite the fact that the connection's link rate hovered at about 300M bps. The Marvell-based products did not interoperate at high speeds with any other products in our tests. The link rate topped out at the 802.11g-maximum 54M bps, which produced the expected 802.11g performance (in the neighborhood of 20M to 22M bps).
