Anonymous users2024-02-07The IP address cannot be renewed, a computer must have a valid IP if you want to surf the Internet, if the TPC IP attribute on your computer is set to automatically obtain the IP, the server used to issue the IP address is the DHCP server, it has a validity period for the IP address issued, and the user is required to renew after the expiration date, what you said can not be renewed can be solved in this way: if you use the route as DHCP, restart the route; If you are adsl to surf the Internet, first ipconfig all under cmd to see your IP, if so, then it means that there is a problem, please use ipconfig release enter and then use ipconfig renew to get it again, see if it becomes if it is, then right. This means that your computer is ready to get a new IP address.
2.Problems with duplicating the game. Manually install a network card on your computer A that doesn't have its own network card, and it's more than 20 yuan.
Set it to automatically obtain the IP, and then share the game directory on the machine B with the game, go to the online neighbor on A and find B and copy it directly from it.
For example, if you automatically obtain the IP address, you can directly set it below, and if you use this IP address, it will become a fixed IP address, and it will not be renewed next time.

Anonymous users2024-02-06It's nothing to do with telecommunications!
The network is generally only given a public IP, and then the company builds an internal LAN through routers and switches, the IP used in the LAN is generally private and can be dynamically allocated to the employee PC through the DHCP server, there is an IP address pool on the DHCP, you can limit the number of IP allocated, if your company has 100 computers, and only 80 IPs are set in the address pool, then there are 20 computers that cannot automatically obtain the IP.
You can go to your network administrator for this question and ask him to set it up on DHCP!

Anonymous users2024-02-04Generally this situation occurs, if it is an ARP attack in the LAN, if ADSL surfs the Internet, the network cable is generally not plugged in, try again, the wireless route is not set up, you should be able to restore the production settings.

Anonymous users2024-02-03There are many reasons for this problem, if it is to obtain the IP automatically, see if your DHCP service is turned off, and set it to automatic in the management tool - Service - DHCP Clint.
If it's a fixed IP, try a different IP.
You can also try restarting the local connection (disabling it and then enabling it).
If that doesn't work, bring up the command prompt and enter the following command: netsh int ip reset c: and then fill in the IP again.
If that doesn't work, contact your school's network administrator.

Anonymous users2024-02-02It's okay to set the IP yourself, don't renew, your renewal may expire.

Anonymous users2024-02-01In this case, in addition to turning off the route, restarting the computer and unplugging the network cable, there are three situations in this phenomenon, one is that the number of computers used by the brain (that is, the number of IP allocations) is set in your route, and someone is giving your network at this time; Second, the computer can't find the IP configuration file; Third, the IP allocation of the extranet is full.

2. Check whether the AP is working normally, and you can power off and restart it once.
3. Check whether the configuration of the AP or wireless network has been modified.

Step 1: Please determine whether the speed of the whole machine is used or just the slow Internet speed? If the whole machine is slow, it may be caused by insufficient space in the computer system, low computer configuration, or computer poisoning, please rule out the above possibilities one by one. >>>More

Because the IP address space is insufficient, it is impossible for telecommunications to assign a public IP address to each user, so there are many ways to use experimental addresses, that is, many conversion technologies are used to solve the problem of IP addresses, such as: a school may have tens of thousands of computers, but the current IPv4 address can not be allocated so much, so you can use NAT technology to convert the intranet address or the experimental address into the address of the public network, and some use the address pool. In this way, from the outside world, it is one of those public network addresses, and the general Internet café often has only 1-2 addresses, so after the conversion, it is always that address, and the current IP address in China is charged 100 yuan for 1 month, so that the Internet café may use less IP address nearby.
