DWA-142/EU Wireless 300Mbps 802.11N USB-2.0 Adapter

We didnÂ?t have a router (or an access point) based on the Top Dog chipset at the time of our tests, so we could only see how MarvellÂ?s chipset behaved with other developersÂ? chipsets. To be specific, we tested the D-Link DWA-142 with routers based on chipsets from Atheros, Broadcom and Ralink. These routers have already been tested in our labs, and we know their capabilities well enough. And weÂ?ll check out the D-Link DWA-142 with a router based on the Marvell chipset as soon as we have such an opportunity.

We used the following hardware and software for the tests:

• Category 5e Ethernet cable
• DWA-142 USB-adapter
• Linksys WRT300N v2 router (Atheros)
• ASUS WL-500W router (Broadcom)
• Edimax BR-6504n (Ralink)
• Centrino notebook
• PC with a mainboard that has an integrated Gigabit Ethernet controller
• IxChariot (High_Performance_Throughput scenario)

First we tested the speed of router-adapter (LAN-WLAN) and adapter-router (WLAN-LAN) connections using the High_Performance_Throughput scenario of the IxChariot program. The connection was established near the routers with WPA2-PSK encryption using the AES algorithm. This is the standard encryption for Draft N, and it is going to be such in the official 802.11n specification. We used the latest driver for the adapter and the latest firmware for the routers.
