Build a network at home (install a wireless router)

About the installation location

 Regarding the installation location of the wireless broadband router (hereafter referred to as wireless router), if it is an FTTH line, it will be near the entrance of the optical fiber cable. It is also possible to extend the LAN cable from the port to the ONU (optical line terminal unit) and pull it to any location in the house. It flies well and has a radio output enhancement function.

 Since the radio waves reach far, I don't think there is much need to worry about where to install it. Depending on where you install it, just by installing one, you can connect wirelessly in a fairly wide range, even on the first or second floor or in a remote room.

About connected devices

 It is recommended that the wireless LAN router to be purchased has about 4 wired LAN switching hubs. It is convenient to connect a NAS or a printer. The connection image is as shown below.

 A modem connection is required. ADSL line, FTTH line, CATV line cannot be connected to WAN without connecting to a modem. * In the case of FTTH, it is called an ONU (optical line terminal unit). As shown in the diagram above, it is convenient to connect devices shared by the family, the main computer, and servers to the wired part of the wireless router.

 It is convenient to connect devices shared by the family around the wireless LAN router. It is possible to install them in separate locations, but it is easier to place them in one place without having to move them around for maintenance and operation management later.

The image of the room where the wireless LAN router is installed is shown in the figure below.

Even if you use a wireless LAN router with strong radio waves, there may be places where it is difficult for radio waves to reach. In that case, you can solve it by:

Corresponding with a repeater that can relay to the blind spot of the radio wave

  • Use a repeater that can relay to the blind spot of radio waves.
  • Use an external antenna that extends the communication range.

 If you are using a device with weak radio waves or if there is a place where radio waves are difficult to reach, connecting an external antenna will allow you to extend the communication distance and relay to blind spots where radio waves do not reach.

 Regarding the external antenna, make sure that it can be connected to your wireless LAN router or wireless LAN card before purchasing. You can check by going to the manufacturer's website.

External antennas include omnidirectional antennas and directional antennas.

Omni-directional antenna : The reception area is 360° horizontally, and you can change the radio wave sensitivity from horizontal to vertical by adjusting the angle of the antenna part. Suitable for two-story houses.
Directional Antenna : A directional antenna that is ideal for extending distance in a specific direction.

Depending on which direction you want to improve the radio wave sensitivity, the external antenna to be selected will change.

Initial wireless router settings

 If you are confident in your network knowledge, you can set up and handle any product you purchase. However, most of the basic settings for recent wireless LAN routers are factory-set, and most of the necessary settings are already done, so you may not have to do anything other than setting up a connection to your provider.

 You will be able to set up from the attached software or from the web screen by connecting to HTTP, but since the attached manual does not have much explanation, I think that you will download the manual from the manufacturer and set it up.

 Some wireless routers come with an easy setup feature. If you are new to networking, I think that this simple setting function will be a strong ally. Just press the button on the main unit and it will automatically determine and set it. But sometimes it doesn't work.
