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. The results were gathered by sending data from the ASUS notebook to the server at different distances with the built in adapter and a TP-Link TL-WN821N and average transmission speeds were recorded for each.
We compared the ASUS WL-500g Premium V2 against the D-Link DIR-655 set to allow b and g connections only. All wireless tests were completed with WPA2 Personal (with the AES cipher, as it has been proven to provide better performance). The router was placed in the exact same position as well as the notebook at its various testing locations for fair comparison.
Since the WL-500g Premium V2 is also a file and print server, I tested file transfer speeds (using a Maxtor One Touch 120GB USB drive) and sent several test prints to a HP LaserJet 1020.
- Connection Speed
As you can imagine, it was a little bit of a slowdown from the 300Mbps connections of the N specification routers and adapters. The average connection for both adapters was 54Mbps. This was at all ranges used for testing.
Now for the fun part; to test the speed of the ASUS WL-500g Premium V2 I chose three common working points inside my house. One was in the lab within 10 feet of the routers; 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.

As you can see, the bandwidth is at the lower edge of what is needed for smooth video playback and completely beyond what is needed for HD Video streaming. File transfer is also going to be hindered by what we see here.
In real-world testing, printing was performed without any issues at all. File transfers seemed a little sluggish and I was not able to watch any HD videos at longer ranges due to some pretty bad audio and video stutter.
