V1.0.11.126_10.2.112 firmware blocking NTP?
I noticed a new issue last week after updating my R7000 to firmware version V1.0.11.126_10.2.112. Eventually the R7000 seems to block devices on my LAN from accessing NTP servers on the internet. I...
It took several more days of testing that included what appears to have been a cable modem-related hiccup to convince myself that R7000 firmware version V1.0.11.128_10.2.112 doesn't block NTP synchronization a day or two after installation/router reboot. Netgear appears to have resolved the issue that was introduced in firmware version V1-0-11-126-10-2-112.
I noticed this morning that firmware version V1.0.11.128_10.2.112 was released last week for the R7000. I pushed the update out to my R7000 a few minutes ago. NTP was able to synchronize with no issues once the router rebooted, but that was also the case after I upgraded my router to firmware version R7000-V1.0.11.126_10.2.112. I will try to remember to check NTP again tomorrow to see if it is still able to synchronize with a time server. Fingers crossed.
After 24 hours, a Mac on my LAN is still able to synchronize time via NTP. At least tentatively, R7000 firmware version V1.0.11.128_10.2.112 seems to have resolved this issue. Will check for synchronization again tomorrow morning before delcaring the problem resolved.

Be sure to save off a back up configuration to file for safe keeping. Saves time if a reset is needed.

Enjoy.Honestly, I'm not sure I've ever had to reset one of the numerous Netgear routers I've used over many years, but that's good advice. I always keep a relatively recent configuration backup on hand just in case.
