IPv6 was working last week...

We had IPv6 connectivity last week, but our IPv6 prefix changed over the weekend, and now no hosts can connect to any external host (e.g. ipv6.whatismyv6.com). Any idea what happened?

Re: IPv6 was working last week...

I have noticed that sometimes when my prefixes change, i need to delete/clear my routers "DUID" and then renew the lease.... not sure if your router gives you that capability, though. I am assuming you have tried a modem reboot?

I first thought it was the router, but then I tried several computers (Windows, MacOS, Linux) that were connected directly to the modem and had the same problem.

 

No, I haven't tried a modem reboot. I'll try that next.

Rebooting the modem solved the problem. I had to power-cycle it because the login page wasn't working.
