IP Conflict in LAN IP addresses cannot be configured manually

If it is an IP conflict, it should be the same as the landlord's IP before it will conflict. The automatically set IP address is automatically assigned by the router, and the automatically assigned IP address will not conflict, that is, the automatically assigned IP address is not the same. The performance is the same for manual and automatic settings, and there is no difference.

For example, I tested it, and the landlord's ttl=64, and mine was ttl=128, and my network adapter was different from the landlord's, is it because of this? This should be the relationship between the network cable, and there will be such a situation if the network cable head is not done well. Sometimes it shows that the local connection is normal but you can't go up to anything** ask for a high finger to point down.

This is normal. For example, if there is no signal on the cat or the router dial-up is not connected, it will be impossible to connect to the Internet. You can enter your own computer gateway in the ** column when you can't access the network, and enter the router to see if the router is not connected to the Internet.

Let's check the reason again!

Try another IP, try between 1 254.

When the mobile phone is connected to the network, it shows that there is no IP assignment, which means that the number of devices connected to the current router has reached the upper limit, and a new IP address can not be assigned to the mobile phone device, so it cannot be connected to the network.

Other reasons: 1. If the network equipment is faulty, if it is a wireless router, it may be that the DHCP service of the router is faulty, or the router is set incorrectly, resulting in the inability to assign IP addresses normally; If the wired router is old, the wired router may not be set up correctly, or the DHCP service of the wired router is faulty, resulting in the inability to assign IP addresses properly.

2. IP address conflictIf there are multiple devices in the same network and all use the same IP address, then IP address conflict will occur, resulting in the device being unable to obtain IP address normally.

3. Incorrect device settingsIf the network settings of the mobile phone are incorrect, such as the incorrect IP address set, or the DNS server set incorrectly, it will lead to the inability to obtain the correct IP address, resulting in the inability to connect to the network.

4. Network congestionIf the current network congestion is severe, the DHCP server may not be able to respond to the device's request in time, resulting in the device being unable to obtain the IP address normally.

5. Check whether the wifi network is normal, and whether the same wifi is connected to other mobile phones, and confirm whether it is wifi or mobile phone. If it is due to Wi-Fi, please restart the wireless router to check. <>

Now that we are connected to the local area network, the upper-layer router will automatically assign an IP address at random. What should I do if the system prompts that the IP address is the same as the IP address of other devices in the LAN? In fact, we can manually specify the IP address of our own computer to solve this problem.

2.Click quot to view the network properties quot:

3.Find the current IP address, here is quot192 168 . 31 . 110 quot；

4.After that, the pre-model changes the IP and clicks on the change adapter option quoton on the upper layer:

5.Double-click the NIC you are currently using to open the current network status

6.Click the quotProperties button:

8.Click quot to use the following IP address quot and fill in a new IP address. The old IP was recorded before, and the new IP only needs to be changed to a tail number.

By default, the subnet remorse mask is that the default gateway cannot be changed. It's in the previous property information. Under DNS, if the router provides this service, you can fill in the gateway address, if not, you can search for the address of the DNS server from the Internet.

9.After the final confirmation, the IP address is changed, and it wins Don't conflict with other devices in the LAN.
