ASCII.jp Techniques that use the useful functions of routers that are often overlooked

To connect multiple PCs to the Internet, a broadband router (hereinafter referred to as a router) is required.However, if you enter an account information and a connection destination for the equipment used by many people, it can easily connect to the Internet, and it is a device that is not usually aware of its existence, so that ability is often used.。

Currently on -market routers have a variety of functions besides internet connections.A router that is not properly set is like using only 10 to 20 % of the potential.If you learn the secrets of the router setting, you will be able to use the remaining abilities.This time, I will introduce how to use routers.

It's a waste to use a router with a variety of functions!Let's open the router setting screen after a long time

Review the settings and improve the wireless communication speed

Even if an optical line is used for the net connection, the wireless LAN may be a bottleneck and the communication speed in the house may not be reached.In order to enjoy the convenience of the high -speed line, we want to maximize the communication speed of the wireless LAN.

Nevertheless, wireless LAN has many standards, and each has multiple operation modes, so it is difficult to grasp.However, if you want to draw out the performance of the device you are using, check the settings again.This time, I will explain the NEC Access Technica broadband router "Aterm WR8700N" as an example.

"Aterm WR8700N USB Stick Set" of NEC Access Technica.The actual selling price is around 16,000 yen

As is well known, as a general wireless LAN standard, IEEE 802.11a/b/g/n is used.The 11b has a maximum speed of 11Mbps, 11a/g is 54Mbps, and 11n is 300Mbps.The latest wireless LAN devices and laptops are compatible with 11N, but many mobile game consoles and old laptops are only 11b/g.

In the past router, there was only one wireless LAN operation mode, and the mode that matched the device had to be specified, so to use these game consoles, set wireless LAN to 11b/g.I had to do it.However, a router with a "multi -SSID" function can use two access points with one unit.Game consoles are connected to 11B access points, and laptops are connected at high speed 11n.

11n is safe because high -speed communication is possible and strong security can be applied.If you're using 11B or 11g somehow, check the function of the router.

You can use two SSIDs, primary and secondary at the same time

2 wireless LAN routers in Japan.4 to 2.5GHz band and 5.15-5.35, 5.47-5.The radio wave of the 725GHz band is used.Furthermore, this frequency band is separated into multiple channels and is connected on a channel set on the router.There is no difference in speed even if you connect to any channel, but if there is another wireless LAN device using the same channel within the range of radio waves, interference may occur and the speed may decrease.If you feel that the wireless LAN speed is slow, changing the channel may improve.

Change of wireless LAN channel (within red frame).If you are interfering, changing may increase the speed.

You can change the channel appropriately until the communication status improves, but if you want to set it properly, check the radio wave status.If you are investigating the surrounding wireless LAN access points, "Inssider" is recommended.You can monitor the connection status of the wireless LAN device used nearby in detail, so you can change the settings to the empty channel.In apartments, there are many cases where completely vacant channels are not found.In that case, set the channel with relatively few users used.

Check the usage status of the channel with "Inssider"

Most of the wireless LAN users are 2.Using the 4GHz band, the 5GHz band is surprisingly empty.Therefore, if the connected device is compatible, use the 5GHz band 11a or 11n.Without channel interference, the communication speed should be surprisingly improved.Some of the latest routers have a function to automatically use channels with good radio waves.In that case, you can always communicate in a good radio wave state, so you should always be effective.
