Re: IPv6 Internet Connectivity Issue Spectrum's internet transport network uses IPv4. If you purchase equipment to utilize IPv6 on your home LAN, or to communicate with another customer on Spectrum's network who uses only IPv6, you are responsible for programming your router unit.

After rebooting, check if you are still facing ‘IPv6 Connectivity: No network access‘ on your computer. Fix-2 Uncheck IPv6 settings-1. Press Windows key+R to launch Run window on your computer. In Run window, type “ncpa.cpl” and then hit Enter. 2. By using 128 bits, IPv6 can include numbers, letters, and longer addresses. 2001:1890:1c00:3113::f:3005. With so many possible combinations, IPv6 can accommodate virtually unlimited devices and websites. Are we leaving IPv4 content behind? No. The move to IPv6 won’t affect how you access IPv4 content. No, your ability to access the internet will not change as a result of this Fios network upgrade. All the content that is currently available to you via IPv4 will continue to be available. When the Fios network upgrade is complete and you have an IPv6 capable router, you will be able to view both IPv4 and IPv6 content.

Hi @wally75 Welcome to the community! Which router are you having problems with? Is it R6400 or R7800? If you have problems with R6400, kindly post your inquiry under R6000 Series AC Routers.

IPv6-test.com is a free service that checks your IPv6 and IPv4 connectivity and speed. Diagnose connection problems, discover which address(es) you are currently using to browse the Internet, and what is your browser's protocol of choice when both v6 and v4 are available.
