Exterior and Interior Design

Right now, the TEW-633GR and TEW-672GR are the top of Trendnet’s wireless router line-up. The exterior design of each device follows the same style indicating that these are top-end and expensive products. The black glossy case with three antennas looks stern, even austere. The exterior is impressive indeed. The TEW-672GR is noticeably smaller than the TEW-633GR although not inferior to it in functionality. In fact, the TEW-672GR is one of the smallest and lightest Draft N routers available. The glossy surface of the case of both models may be a problem, though. When we took the new TEW-672GR out of the box, we saw fine cardboard dust on its case where the router had been rubbing against the packaging. The surface of the TEW-633GR didn’t look very impressive after two weeks of heavy use, too. The second drawback of the TEW-672GR is that its antennas are not detachable, so it won’t be easy to use external antennas.

The TEW-672GR can be placed flat or wall-mounted using the fasteners in its bottom. This model is ventilated through the few holes in the side panels of the case. This seems to be enough because the router doesn’t get hot at work. Its components just do not generate much heat.

Notwithstanding the difference in size, the front and back panels of the TEW-672GR are similar to those of the TEW-633GR. The front panel carries indicators reporting the router’s current status. These indicators are implemented as shining vertical stripes (from left to right):

  • Power
  • Four indicators of the LAN ports
  • WAN port indicator
  • Wi-Fi indicator
  • Copying of settings via WPS

The indicators are all the same and are placed in a row, which is not very handy. They are bright, but not annoyingly bright, and can be seen at almost any angle and from a big distance. They are quite good overall.

The back panel offers the following (from left to right):

  • Power connector
  • Reset button
  • Wi-Fi mode switch
  • WAN port
  • Four LAN ports


Besides that, there is a WPS button on the side panel for secure setup of the wireless network.

The other interesting things are hidden inside the router, so we took it apart. Besides the locks at the bottom, the parts of the case were fastened together with two self-tipping screws that we found under the rubber feet.


The system PCB occupies the entire case. It wasn’t easy to take it out because some of the elements were sticking out of the case. Moreover, the PCB was additionally fixed with special holders that prevented it from moving diagonally. Anyway, we managed to extract and scrutinize it closely. All the components are installed on the top side of the PCB. The mounting is very neat, just as you can expect from such a presentable product. There are almost no empty seats on the PCB, which indicates that this router model is not a cut-down version of something bigger.
