Can't access router settings on AC66R

[Darcy]

I recently switched to IPV6 on Comcast. I cannot access my router settings now. The address that always worked was http://192.168.1.1/. Now I get the 401 unauthorized error message.

Nobody can answer this?

I reset the router twice. When I do this I have access but then it goes back to 401 unauthorized after 30-60 minutes.I reset the modem as well...very strange.

If you are using Firefox

Tools-> Options -> Advance -> Network -> "The following websites are allowed to store data for offline use". Remove the entry for the router.
