    This is not a very common problem, but it can happen, especially if you have multiple routers on the same home network.

    To make sure you have a valid IP address, follow these instructions:


    Step 1. Right-click on the Internet icon in the lower right corner of the screen.

    Step 3. Click Change Ethernet Adapter Settings >> Properties> Internet Protocol Version 4.

    Another step: after logging into the Internet Protocol version4 Select the Obtain an IP Address Automatically and Obtain DNS Server Automatically options. Get an IP address that doesn’t conflict with others or contains invalid numbers. Instructions

    Step Click any Apple menu in the upper left corner of the screen.

    Step 3. Click the desired network connection (eg Ethernet or Wi-Fi).

    Step 4. Select “Configure IPv4”. Select the option to configure the IP address. To have the IP address generated entirely by yourself, select Use DHCP. This is the easiest way to do it.
