While troubleshooting other issues I noticed that my laptop (Windows 10) gets a IPv6 address when directly connected to my modem (SB6121) but there's no IPv6 when going through my router (Linksys EA4500.) Looking around it appears that the router isn't getting an IPv6 address. I've tried releasing/renewing it with no luck. In the status report for IPv6 it just say's "Connecting".
"IPv6 - Automatic" is enabled. Has anyone gotten IPv6 to work with this router?
Sorry to disappoint, but according to Linksys at http://www.linksys.com/us/support-article?articleNum=135685 the EA4500 is not capable of supporting IPv6.
Comments on this unit are mixed with most suggesting IPv6 can work but that there are insufficient adjustments for "non-standard" (like TWC) systems.
If you want IPv6 access to the greater Internet on all your LAN devices I think you should consider getting a gateway device that properly supports both being a DHCPv6 client and being a DHCPv6 server. Or at least one that has clear instructions.
