What are the precautions when connecting a Wi-Fi router to the net line?

After purchasing a Wi-Fi router, did you keep "IP addresses and passwords for accessing the setting screen" and "initial SSID and encryption keys" when opened?Next, let's look at the points of the work of connecting the Wi-Fi router to the line.

As we have explained so far, 1) There is already a router on the device on the Internet line side, and the router function inside the Wi-Fi router is turned off and used as a Wi-Fi access point (AP) [*1]Or, 2) It is necessary to identify whether to connect to the line by using the router function of the Wi-Fi router without a router on the line side device.These two modes are often switched by the body switch, but depending on the product, it is necessary to switch from the setting screen.Although it is not certain, if the line side device has about four LAN ports, it can be predicted that the router function is installed, and if it is only one, there is no router function.

This mode switch is basically connected before connecting to the line, but if you don't know which state you should use in your home, turn on the router without thinking deeply and Wi-Fi.It's okay to connect the router.If there is no router in the front stage (line side device), the line connection will be treated on the first access screen [*2], and even if there is a router, the router will operate in double, and the IP address will be an IP address by the "DHCP server".It is assigned and connected to the Internet [*3].

If it is connected with a double router, connect it to Wi-Fi later, check the condition, and switch to the access point (AP) mode.This concrete method will go down next time.

[*1] ... Sometimes called "bridge mode".

[*2] …… When connecting with a FLET'S line by the “PPPoE” method, the connection information provided by the provider is required, so enter and connect.If you connect with other "DHCP", you will be connected without setting anything.

[*3]… “DHCP server” is one of the functions of the router, and IP addresses of devices connected to LAN ports and Wi-Fi (mainly IPv4. The IP address is automatically set in IPv6.However, at present, it is inconvenient if IPv4 cannot be used).At the same time, refer to the "DNS server" information that converts the URL domain name to an IP address.The IP address is the destination of the data, such as the address represented by the numerical values.Unless this is allocated, communication cannot be done.In AP mode, DHCP is off.

The order of the connection work is "Confirm the power on the line side device and the start of the start" → "LAN cable connection" → "Wi-Fi router power turn on".Be sure to learn as a basic operation to turn on the power from the line side device, including a power outage.This is because the information for connection is allocated in this order.If you turn on the Wi-Fi router without waiting for the start of the line side device and the connection, the net connection may not work.

Connect a color-coded port with Wi-Fi router with "WAN" or "Internet" to the LAN port of the line side device.However, when switching to access point mode, there are some models that use only LAN ports instead of WAN.Many products can use WAN and LAN in parallel during access point mode.In this case, both WAN and LAN have the same roles port, so you may be connected to any port without worrying about it.

As for the LAN cable to be connected, I wrote it in the 5th series, but I will always check if it is more than "CAT5E (category 5e / enhanced category 5)"."CAT5" is useless.These two are easy to make mistakes, so if you want to buy anyway, you should put them as "CAT6".Currently, CAT5 cables are unlikely to be sold, but if you use the cable in the room in the room, it will be "CAT5".With this, the high -speed line is also reduced by half.Be sure to check the diverted cables because it is a common pattern with a common problem with consultation that does not come out as expected.

If you use the attached cable for the Wi-Fi router you bought, there is no problem, but most of the devices will usually only connect to the side, so if you prepare a short cable, it will be smart.

After turning on the power, wait a few minutes to complete the start.From the next time, I will try to access from the long-awaited smartphone Wi-Fi.
