I have been reading MANY forum posts related to this, so I am now a tiny bit more knowledgeable. Note that I am a legacy developer, an old dog that can't learn new tricks. I am not exactly sure when this started, I don't think this has been happening since I started using this router.

I will try to outline what is happening and what I have found and any other information that might be relevant.

Had a Nighthawk X6 AC3200 and never had these problems.

Last year, we finally got 1G service. Never had problems with the X6 except for the coverage. So eventually we decided to upgrade even though the X6 was still going strong. Not my decision and didn't want to argue the point, if you know what I mean.

Bought the RAX80 last year also. It works great. Coverage throughout the house is amazing. No extenders needed.

FW version is V1.0.1.70_1.0.30 which I am pretty sure is the latest.

I can't remember when this started happening, I would say a few weeks ago. Note that I do not have any issues with any other connected devices, wired or wireless. I play a game on Xbox that requires a constant online connection. Many of the activities require a team, and players are penalized for leaving. The first time, you get a warning. The second time, you are banned from the activity for a set period of time.

The game keeps booting me out with a code that indicates loss of network connection. My Xbox is directly wired to the router, not using wireless. The IP address is manually assigned.

It finally dawned on me to check the router logs. 100% of the time that I am booted, I can see an entry in the router log, "Time synchronized with NTP server". This is happening a lot. I have copied to a text file and included the router log entry immediately before the event and the one after the event, if that helps.

In going thru the forums, I see that this is normal to occur in half the lease time. I found this information, and confirm that the lease is set to 6 hours. So this sync would occur at 3 hour intervals.

I think I also understand what this lease does. On the previous router, devices would accumulate, I assume because the lack of renewal time. I was okay with just rebooting the router weekly, no big deal.

The max number of devices on our network is around 2 dozen.

While I now see a pattern of time sync at every 3 hours, there are instances where it occurs within 30 minutes.

I will include the router log at the bottom, not sure if there is any security risk in posting this?

Is it possible to change the lease time? I would like to change it to 24 or 48 hours. I read something about using a telnet to the router but that seems scary, if there is no interface. Heaven knows what kinds of damage I could do.

Not sure if it matters but I also noticed that in the NTP settings, the box for daylight savings time is not checked.

What causes this sync to occur? Is it a device on my network requesting this? Not the 3 hour intervals, but when it occurs before the 3 hours has passed. There was one day when I just gave up and signed off because I got bounced like 3 times in 2 hours.

I am 99.9% sure that this lease time has nothing to do with my ISP.

I truly appreciate any input that anybody can give. I know nothing about networking, and don't have enough grey matter to understand everything that I have been reading :smileysad:

I really like Netgear routers, have had Nighthawks for a LONG time, but if I can't figure this out....besides Ubuiqity (tried that and failed), would anybody have a recommendation for another decent router?

And from the game's help site for the error code that I get:

Please note that a temporary drop in your network connection will disconnect you from Destiny, but may not disconnect you from other services such as Xbox Live/Playstation Network and party chat.
