Description/Explanation of Issue

In the Windows 11 Settings menu, you must have valid primary and secondary DNS server IPs assigned for each network interface for Windows to consider the configuration valid. A DNS server translates URLs (i.e. support.etcconnect.com) into an IP address that a computer can communicate with. Since, in most cases, there is no access to the Internet on a lighting network, no DNS server is required. However, since the Windows Settings menu for configuring IP addresses requires it, we need to assign one manually.

Alternatively, the older Control Panel network adapter configuration tool allows an IP configuration with no DNS server, but is buried deeper in the OS. If you have experience setting the IP address for Windows versions prior to 10, this may be a more familiar method. Instructions for both approaches are below.

Solution (Windows Settings)

While it is not necessary to point Windows to an active DNS server on a lighting network, and any arbitrary IP can be used for the primary and secondary addresses, you may wish to assign a valid server in case you'd like to use a static IP address on your network adapter for Internet access later. There are many public DNS servers available. A few popular DNS providers are:

Provider Preferred Alternate
Google 8.8.8.8 8.8.4.4
Cloudflare 1.1.1.1 1.0.0.1
OpenDNS 208.67.222.222 208.67.220.220

Fill in the above addresses in the Preferred and Alternate DNS Server fields, and the menu will allow you to save the new configuration.
