Convenient tricks that can solve "Wi-Fi troubles"
Basic edition 14th
[A] This is a mechanism for automatically performing the necessary settings to use the network.
"DHCP" is an abbreviation of "Dynamic Host Configuration Protocol", and is a mechanism for automatically performing basic settings for communication using a network.
To communicate with a network where "IP (Internet Protocol)" is used, you need to set an IP address, subnet mask, default gateway, and DNS server addresses.DHCP is a mechanism for automatically performing these settings.If you use DHCP, you will automatically make these settings just by connecting the computer to the network.
In order to automatically set the network with DHCP, there is a "DHCP server" in the network, and it is necessary to enable DHCP on the client PC and smartphone side.The function of the DHCP server is installed in many broadband routers.
When using the functions of the DHCP server mounted on a broadband router, there is usually no need to make a setting.However, if you want to change the range of the assigned IP address, you need to set it separately.

The deadline for allocation of IP addresses by DHCP is defined.There is a mechanism to continue using the same IP address even if the deadline expires, but depending on the situation, the IP address may change when the computer is restarted.
However, if you use a computer as a server, there may be situations where the IP address changes.Therefore, it is a function that always assigns the same IP address to the specified MAC address in advance, and many broadband routers are compatible.
