NetGear Powerline Av 200 Wireless-N Extender Kit XAVNB2001 review: NetGear Powerline Av 200 Wireless-N Extender Kit XAVNB2001

Other than the little misinformation, we had no problem setting up the XAVNB2001 kit. The two adapters worked very well together in our trials. As a wireless access point, the adapter works only in the 2.4Ghz frequency band and supports all variations of wireless encryption, including WEP, WPA, and WPA2.

Performance
The XAVNB2001 kit is the fastest powerline kit we've tested, scoring 56.2Mbps. This is the sustained throughput speed, and at this rate, it can transfer 500MB of data in slightly more than 70 seconds.

The kit also impressed us with its wireless performance. In the close range throughput test, it scored 41Mbps, right about the average when compared with regular Wireless-N routers. It scored 27.3Mbps in the 100 feet range test; in the mixed mode test, where it was set to work with clients of different wireless standards at the same time, it registered 37.6Mbps. These numbers were about average.

The most impressive thing about the XAVNB2001 kit, however, is its range. Its wireless signal could reach as far as 280 feet in our testing facility, which is among the longest of wireless routers. The device also passed our 48-hour stress test easily without disconnecting once.

Note, however, that the kit's throughput speed, though comparatively fast, isn't ideal for multiple high-def content streaming. In our anecdotal tests, the kit worked fine with a single streaming task, both with its powerline and wireless signal. When we wanted to stream the same movies to different players at a time, however, we experienced intermittent rebuffering.
