What is an IP address?
IP address refers to the Internet Protocol address. It assigns a logical address to every network and every host on the Internet to shield the difference in physical addresses. We can simply understand the IP address as the "home address" in real life. Only by knowing the "home address" can the courier brother deliver the things we need to our homes.
The same goes for wireless networks. Take the home network as an example. It is the router that provides wireless network for networked devices. If the networked device wants to connect to the wireless network, it must first obtain the IP address provided by the router, and then obtain the permission of the router to connect to the Internet.
When a networking device connects to a wireless network, the router needs to refer to the protocol rules to allocate a dedicated IP address to the user's networking device. During the allocation process, the networking device will automatically obtain the assigned address. If it cannot obtain this address, it will prompt " Failed to obtain IP address"; if the router does not or cannot assign an IP address, it will prompt "No IP address assigned", which is equivalent to the courier brother having no delivery address and the courier being unable to deliver the destination.
How to solve the problem of "No IP address assigned" when a networked device prompts?
1. Restart Dafa~, unplug the power of the router, wait 1 to 3 minutes, and then plug the power cord back in. This is equivalent to restarting the router. Then connect to the wireless network of the router, and the connection may be normal.
2. It may be that the router has turned off the "DHCP" function. You can contact the network administrator to obtain the IP address; if it is a home router, you can restore the router to factory settings, then enter the router's background interface and enable the "DHCP" service.
Generally speaking, these two methods can solve the problem. If it still doesn't work, you should consider that the router is damaged and solve the problem by replacing the router.
