We used PerformanceTest 6.1 by PassMark which you can find out more information about here. It has a handy Advanced Networking section which is perfect for our testing.


Doing our best to emulate a real-world performance scenario, I setup a server running Windows 2008 (x64) Server, (2x Xeon Quad Core 3.0 GHz 1333MHz FSB, 4GB DDR2 FB-DIMMS, 2x 146GB SAS drives in RAID 1) and the client PC was an ASUS G2S -X1 With built-in Intel 802.11n adapter running Windows 7 RC1 (build 7100) x64. The results were gathered by sending data from the ASUS notebook to the server at different distances with different adapters and determining the average transmission speed.


We compared the MvixUSA Nubbin against the TRENDnet TEW-645UB adapter, the TP-Link TL-WN821N and the built-in Intel Pro Wireless (N) adapter on the ASUS G2S X1. All wireless tests were completed with WPA2 Personal (with the AES cipher, as it has been proven to provide better performance) and 802.11n + 802.11g wireless mode enabled on our D-Link DI-655 router. I chose to leave both n and g enabled as this is a more realistic simulation of a normal home wireless network. The router was placed in the exact same position as well as the notebook at its various testing locations for fair comparison.


- Connection Speed


The Nubbin connected to our network without any issues and showed a 150Mbps speed for all of our testing. However, I did find that its range is rather limited; once I was out of direct line of sight of the DIR-655 the Nubbin's signal strength dropped to just over 50%. The link strength remained strong but the drop in signal strength ended up showing as speed was cut to less than 1/2.

- Bandwidth


Now for the fun part. To test the speed of the MvixUSA Nubbin I chose three common working points inside my house. One was in the lab within 10 feet of the DIR-655; the next was in the bedroom roughly 35 feet away and requiring the signal to travel through a wall containing the main house electrical panel and a "wet wall". The last was outside on the back porch, roughly 45 feet from the router. Both the second and third positions were out of the direct line of sight of the router.

You can see the effect of the smaller antenna here. Within my office (less than 10 feet) the Nubbin stomps on every other adapter I tested. However, as soon as the signal strength dropped, we lost speed. As long as I was in direct line of sight I was ok with a small loss in signal and speed, but as soon as I was in another room the speed that I saw at less than 10 feet disappeared.
