Manually enabling IPv6 on Linksys routers

Internet Protocol version 6 (IPv6) is a protocol introduced to replace Internet Protocol version 4 (IPv4) in order to solve the IP Address exhaustion problem.  Although IPv4 is still being used, some Internet Service Providers (ISPs) already require setting up IPv6 on the router to activate your Internet connection.  
 
IMPORTANT:  Not all Linksys routers are IPv6-compliant.
 
Before enabling IPv6 on your router, you must have the following information from your ISP:
  • Network Setup Prefix
  • Prefix Length
  • Border Relay
  • IPv4 Address Mask Length
Once ready, select from the links below which instructions apply to you:

Using the Linksys classic web-based setup page
Using your Linksys cloud account
