We use the cell broadband, because there are two computers, so I bought a router simultaneously online. In recent days, because of the reloading machine, not how to get it, the machine can only be static to allocate IP addresses to access the Internet. (I used to allocate IP, I didn't know how to get it), if dynamic assignment IP, after reboot, even the router is even can't connect, and IP is observed with ipconfig to be 4 zero. Due to the static allocation IP address, there are some bad places (listening to others, the worms in the LAN may affect the speed of the Internet)
So I resolutely want to get this problem.
Control another, I took the property of TCP / IP for a long time, and the result is still the same. First static allocate IP addresses, then connect the router, then renamed the dynamic assignment IP, you can go online, but after restarting the machine, or old.
Finally, I really can't stand it, I have learned in the Internet. I accidentally see "DHCP", I suddenly think of if there is a DHCP Client to start. Looking at the service of Windows, Sure enough, DHCP Client is manual, and I can't resent my machine. After the machine is restarted, I can't assign IP addresses. The original problem is here. Change the DHCP Client to automatic. Restart the machine, sure enough, everything is OK.
DHCP (Dynamic Host Configuration Protocol) automatically assigns available IP addresses (used within limited leases) and transmits additional IP configuration information. DHCP is a protocol that enables network administrators to manage and assign IP messages to all computers in a network. When we enable DHCP in the network, you can contact ISP on the network to assign a temporary IP address to the computer within this network. The device of this assigned IP address is called a DHCP server, and the device that accepts IP addresses is a DHCP proxy. When DHCP is enabled in the network, one advantage of the dynamic allocation of IP address information is that when a DHCP client is reconnected to the network each time a DHCP client is reconnected, it can be in the public IP address pool of the DHCP server. Assigned to a different IP address.
DHCP allows us to use a central computer (DHCP server) to manage and assign IP addresses through the network. If there is no DHCP, we will have to configure IP addresses and related data for each computer.
