Linksys E4200 tunnelbroker not reconnecting after reboot.

[10010]

I recently got a Linksys E4200 to use with tunnelbroker. However, as soon as the router reboots, it will not connect to my tunnelbroker account ever again. It tries to reconnect, but just says IPv6 Tunnel Status: Undetermined. What gives?

Are settings not being saved? Upgrade firmware?

I know this thread is ancient, but I wanted to provide closure to anyone with the same issue.

The stock firmware on the Linksys E4200 is all-around buggy, and I have since upgraded to an EdgeMAX router, and relegated the Linksys E4200 to switch duty. This new router works wonderfully and tunnels persist after I reboot the router (which is rarely necessary).

In short: the issue was with my cheap router.
