I bought this modem router a few weeks ago, recently I'm having problem with IP address (IPv6) losses.

When I realize "IPv6 Connectivity" on Windows 10 has "no internet" I know that IPv6 is loss.

It happen almost everyday, very annoying, and I'll have to do a modem restart to correct the problem. BTW, I do power off the device daily.

I check firmware upgrade, it is up to date.

I have previously a TD-W8961N without issus.

Thanks for anyone who can help.
