For security the EnGenius ESR9855G offers all the existing variations of consumer-grade wireless encryption including WEP, WPA, and WPA 2.
The EnGenius ESR9855G impressed us with its throughput and range in our tests, consistently achieving the fastest scores we've seen among single-band 2.4Ghz routers.
In the close range throughput test, the EnGenius received a score of 57.7Mbps. At this speed, the router can finish transmitting 500MB of date in less than 70 seconds.
In range test, where the router is set to be 100 feet away from the client, the EnGenius registered 48.5Mbps.
And finally in the mixed mode test, where the ESR9855G was set to work with both N and legacy G wireless clients, it once again trumped all with a 50.8Mbps score, the fastest by a rather large margin.
The EnGenius ESR9855G also offers extremely long range. In our test environment, which is not typically optimized for wireless range, it was able to maintain a stable connection from about 350 feet away, compared with 250 feet of most Wireless-N routers.
However, we did notice that as the range increased, so did the latency. For example, from the distance of 180 feet and beyond, it would take a few seconds before the wireless client started receiving data or connected to the Internet.
The EnGenius ESR9855G, unfortunately, didn't pass our 48-hour stress test where we set it to constantly transferring a large amount of data between wireless clients. During this time, the router's signal was reset a couple of times, disrupting the data transmission. This might not affect regular Internet surfing, or even movie streaming, but it would likely kick an online gamer out of his or her game.

Service and support
The EnGenius ESR9855G is easy enough to use that we think you won't need much support for it. And that's a good thing, as the support for the product seems very sparse. It took us a while to find out that the router's backed by a one-year warranty. At EnGenius' Web site, which is confusing and incredibly slow, you won't find anything but just a photo of the product, a bit of information about the router, and its data sheet in PDF format.
