Other than that, the TEW-639GR lacks other common features found in high-end routers, such as dual-band or guest networking, which lets you create a separate wireless network for guests. The router is also not very comprehensive when it comes to assigning a fixed IP address to a computer in the network. You will need to find out about that computer's MAC address and type it in manually. Other routers can display this information, and you can just assign a fixed IP to any of them with a few clicks.
For security, the TEW-639GR supports virtually all existing encryption methods currently used for wireless routers, including all the variations of the WEP and WPA encryption standards. As mentioned above, the router fully supports Wi-Fi protected setup, so most of the time, you won't have to worry about memorizing the encryption key.
The TEW-639GR met our expectations with its performance, except for its range, which is rather short at about 210 feet, compared with 270 feet in most N routers. Its throughput performance, however, was much better.
In the throughput test, where the router was set up to offer the best possible transfer speed, the TEW-639GR scored 47.3Mbps, which was among the fastest for single-band N routers. At this speed, you can finish transferring 500MB of data in about 80 seconds. In the range test, where the client is put 100 feet away from the router, the score was lowered to 25.7Mbps, which is a little higher than average.
In our mixed-mode test, where the router was set to work with both N and legacy G clients at the same time, the TEW-639GR also scored 25.7Mbps, which is low among single-band N routers.

Overall, the TEW-639GR performed well in our tests. However, it didn't successfully pass our 48-hour stress test, where we set up the router to constantly transmit a large amount of data between different clients for two days. During this time, the router disconnected twice, each time for a few seconds. Though what happened wasn't really bad for most situations, online gamers might get kicked out of the game when this occurs.
Service and support
Trendnet backs the TEW-639GR with a generous three-year warranty (compared with one year for most routers). The toll-free technical phone support is available 24-7, even when the warranty runs out. TrendNet's Web site offers comprehensive self-help tools including the Configuration Emulator , which shows the look and feel of the router's Web interface and its features. There are also other download materials such as manuals and the latest firmware.
