. Select “TCP/IP.” From the “Configure IPv4” menu, select “Manually.”
Enter a static IP address in the IPv4 Address field. Enter any unused address that’s outside the DHCP range of your current address. Do this by changing the last number in your address, but keeping the rest of the address identical to your current one. So, for example, if your current IP address is 192.168.1.143 and you have a DHCP of 50, you might choose the static address 192.168.1.3. See this video
