reason
< br >
1. Check whether mac address binding is enabled on the router
< br >
If your router mac address binding is set to boot, and bound to the specified NIC mac address. And you just happened to set the bindings. Then either unbind or add the new mac address to the binding.
< br >
2. Check whether the router service Settings are faulty
< br >
Many routers turn off some services when they are reset. Check whether the relevant services are turned off. Then open it. For example, if DHCP is disabled, the system cannot automatically obtain IP addresses when IP addresses are automatically assigned.
< br >
3. Obtain the ip address and set it to automatic
< br >
When the router turns on the dhcp service, we set the ip acquisition to automatic in the wireless network properties, so that it is not easy to fail.
< br >
4. Check whether the NIC driver is started and up-to-date
< br >
You can download the relevant driver software to check, and then install. Or go to the official download driver and install.
< br >
If the above several aspects of the inspection still can not solve the problem. So back up your data and initialize the system
In this case, the treatment is as follows:
< br >
1, plug the network cable into another TV, if it can be displayed normally, then the network cable is no problem; If it cannot be displayed normally, repair the network cable connector or make a new network connector.
< br >
2. If the network cable is not faulty, it is likely that the network adapter is faulty. (1) If it is an independent network card, you can reinsert the network card several times to see if it still shows that the network is not plugged in, if it is checked, then the network card is broken, you can directly change a new network card to try again. (2) If it is an integrated network card, the entire motherboard should be repaired by professionals.
