What does it mean when Wi-Fi has no IP address?
When your Wi-Fi has no IP address, it means that your device is unable to obtain a valid IP address from the router or modem. This can prevent you from accessing the internet or connecting to local network resources. An IP address is a unique identifier assigned to each device on a network, allowing them to communicate with each other. Without an IP address, your device cannot establish a connection to the network.
This issue can be caused by various factors, including router or modem problems, network configuration issues, or conflicts with other devices on the network. It’s essential to troubleshoot the problem to identify the root cause and find a solution to restore your internet connection.
