There should have been another button under the front panel:
Its purpose should have been to quickly set up security settings for the wireless connection. But there is only a small hole in the case which is sealed with a “Reserved” sticker. A button can be found under the sticker, but it doesn’t do anything when pressed.
The quality of the case is high, just as you can expect from such a respectable firm as Linksys, but we were surprised to find the router very difficult to take apart. Well, most users won’t ever do that, especially while the router’s warranty is in effect, but those enthusiasts who’ll try to get inside their WRT300N, will have some troubles doing that. Externally, it is perfectly unclear what to start with. It’s only after some scrutiny that you notice that you should first lift up the panels with the vent holes. This will call for a screwdriver and some effort on your side.
To take the PCB out after that, you’ll have to unblock four locks simultaneously to release the translucent front panel. And you also have to unfasten the four screws on the case to take it apart into two pieces and extract the PCB. By the way, the state of things inside the router is somewhat disappointing. There are loops of cables going to the antennas that are just stuck to the case panels with sticky tape.
You expect something more elegant from a device of that class. The wiring and layout of the two cards you can find inside the case is good, however. Every detail is placed logically and not too close to others.
The PCB is wired neatly and cleverly. All the main components are placed on one side of the PCB while the other carries a miniPCI slot for a wireless interface card.
You can notice a few empty seats for more components on the PCB:
Particularly, there is a seat for a PCMCIA slot and for an appropriate controller with accompanying elements. The engineers must have had doubts as to what interface the wireless module would be connected with. There are no unsoldered components here, although there is plenty of room. The new PCB design must have been developed for later models like the WRT350N.
