Points to review the internet comfortable home wiring with the news "Giga Exceeded Light"

Consider reviewing the type and plan of the line and faster the Internet

If you know that the Internet is due to the slow Internet, consider reviewing the type and plan of the line. In that case, I would like to consider using various discounted services. The "Hikari Collaboration Model" (Hikari Collaboration), which is implemented by NTT East and Daiwai Japan, is a mechanism to sell the company's optical lines to other companies. DOCOMO Hikari and Softbank Hikari sell optical lines using this system. In the case of optical line plans using optical collaboration, there is an advantage that switching to other companies' lines can be done without any work. If you are using docomo, au, and SoftBank smartphones, we would like to consider discounts that can be received in a set contract with the optical line. From the monthly usage fee of the smartphone, you can receive a discount by the number of smartphones contracted. Each company has a large discount of 1100 yen per smartphone, and the smartphone for the family is counted to the number, so it is a considerable discount amount in the case of a family contract.

■ Review to high -speed line is excellent

The optical line that exceeds giga is actually a matter of how fast it will be.Introduced NURO Hikari with a maximum communication speed of 2 gigabit/second (GBPS, 1 billion in giga) at the editorial staff of Nikkei PC21, more than three times faster than FLET'S Hikari with a maximum communication speed of 1Gbps.In addition, when a line of NURO Hikari 10g was introduced at another editorial house, about 3.The speed of 5Gbps was recorded.The line speed is likely to fluctuate depending on the time of measured and region, so these examples are only a guide, but it is certain that switching the line can greatly speed up the net line.In the case of a line exceeding giga, I would like to check the inner wiring in the house.If the hub or cable in the house does not support high -speed wired LAN, the speed will decrease.At least I want to prepare Gigabit Ethernet.

■ Speed the current line by switching the connection method

Currently, in the Internet connection method using "IPv4 PPPoE", which is currently used in many providers, the communication speed may be significantly reduced depending on the time of day. One of the causes is the congestion of the IPv4 network. Since the connection capacity between the NTT base station and the provider is small for the demand of IPv4, traffic congestion is likely to occur during the concentration of use. Therefore, I would recommend switching the Internet connection to "IPv6 IPoe". This is an online connection system that replaces the conventional IPv4 PPPoE. IPv4 tends to be low at a crowded time when there are many users. Therefore, we use IPv6, which has low users and high -speed equipment, to simplify the authentication necessary for connection and speed up the Internet. Since the connection of the ID or password is not required for the connection, the net connection setting of the Wi-Fi router is also easier. In an environment that uses IPv6 IPoE, the function called "IPv4 Over IPv6" can be used. This is a technology to send and receive IPv4 communication using IPv6 communication network. The method of providing IPv6 IPoE varies depending on the provider, but if you apply, you often switch for free. No construction is required, and if you apply, the service start date will be notified by email. Sometimes it can be used without applying. In order to use IPv6 IPoe and IPv4 Over IPv6, the Wi-Fi router must be supported. As of mid -November 2021, most of the current models of domestic manufacturers are compatible. Even if you apply to the provider to use the IPv6 IPoe or IPv4 OVER IPv6, the router setting will be connected in the original state if the router is set in the IPv4 PPPoE. To prevent this, return the router settings to the initial settings, automatically judge the type of line, or manually switch to IPv6 IPoe.
