Nighthawk X6 R800 Cannot connect to NTP time servers

[Pyrran]

Just upgraded my firmware to V1.0.4.66_10.1.75

Internet works fine, BUT I cannot connect to ANY NTP time server.

I've tried the default Netgear server, time.nist.gov, 0.us.pool.ntp.org.  Nothing works.

I can ping these servers with no problems.

I really do not want to factory reset my router as I have access control on and 20 devices connected.

Any ideas?
