The wireless connection in draft 802.11n mode was tested using WPA2 PSK encryption with the AES algorithm. These security settings are the default ones in the draft version of the new standard and are likely to remain such in the final version.

LAN-WLAN (TEW-633GR):

The Linksys router is ahead in this test, too. This is especially good because the WRT350N is somewhat inferior to the TEW-633GR in terms of hardware components.

Then we tested the router’s coverage at different distances and with different obstacles. We measured the signal level in five points:

Point 1: Near the router
Point 2: At a distance of 4 meters without obstacles
Point 3: At a distance of 5 meters + two thin gypsum wallboards
Point 4: At a distance of 6 meters + one brick wall, about 30cm thick
Point 5: At a distance of 17 meters + one thin gypsum wallboard and two 30cm brick walls

Here are the results:

The two routers are roughly equals here. The TEW-633GT is ahead in the middle points but the WRT350N is better in the last point. Perhaps the Linksys router is even somewhat better overall in this test.

And finally we tested the router’s USB 2.0 interface. We didn’t expect much from it, actually, because the developers do not pay as much attention to it in routers as in network storage and media players. Anyway, we used a 64K pattern in IOMeter to measure the port’s bandwidth and a 512-byte pattern to measure its latency.

We also tested the router’s FTP-server. FTP remains an important data-transfer protocol, so this test has high practical value. We uploaded and downloaded files with FlashXFP and marked the average download speed reported by the program in the server connection log. We used the following content types: a 700MB DivX movie (L), a 200MB folder with MP3 files (M), and a 200MB folder with photographs (S).

The results are good. The synthetic benchmark produces similar results to the FTP-server test, which indicates a good implementation of the FTP server in this router.
