R7800 keeps dropping its Internet connection
My router (R7800 Nighthawk) is updated to firmware 1.0.2.92. I have a TP-Link EAP 110 Outdoor access Point connected to it, and a KuWfi 300Mbs bridge connected to a 8 port gigabit switch. I also have...
Hi all - I just wanted to report back after monitoring the system for the last 24 hours +.
The problem has been solved - clearly it was an issue with having 2 DHCP servers running, and since I reconfigured the bridge units without DHCP active and with Static IP addresses, everything now seems to be working fine.
Thank you all so much for your help in troubleshooting this, and I am very happy that the R7800 now seems to be doing the job I hoped it would. Cheers
Hi, thanks for your response - no, the internet light on the router remains white and showing activity. I do not connect to my ISP through a modem/router. The ISP provides a small Fiber Optic connection box, (1GE SFU XPON ONU Model# WK-3801-A) which is seemingly just a small 12v dumb box with an optical input for the fiber and a Lan port to which I connect the R7800 (it has the IP address of 192.168.1.1) - no modem our router function at least that I can access and no wireless function. So I am not sure I can do any of the things you suggested. I did run a network diagnostics test on my Mac and found 2 interesting things in the log. (1) " ———————
Timestamp Name Duration Result Description

Conflicting Wi-Fi CC 0.000 Yes 13:55:28.730 Found conflicting country code(s) (cr)
'Arwen-5G' — 8c:3b:ad:19:3a:8f (US)."
It seems the Router network is seen with a county code of "US" and the Gateway with a country code of "cr" (Costa Rica). I wonder if this could be an issue?
(2) I see a couple of pings fail for pinging the WAN DNS server "Ping WAN 1.026 No 13:54:42.725 Could not ping DNS server (17.254.0.22 / 0.00ms / BE / 68 bytes / i=0.100000s / W=1.600000s / t=1.600000s / c=1)"
However there a successful pings on the LAN side to 10.0.0.1
Do these things shed any light on the issue do you think?

What is it that "sees" the router. Where does it display a country code?
Somewhere in the graphical user interface (GUI)?

How did the router get that IP address?
You say that the Netgear genie went for that. This suggests that it found a potential conflict on your network.
It isn't the one that the R7800 would go for by default. It goes for that when it sees something already squatting on the preferable default of 192,168.1.1
This seems to be at odd with your comment:

What has the IP address 192.168.1.1?
You say it is the "ISP Gateway", but then say you don't have a modem/gateway. That is a local IP address. Not something than an ISP allocates to you.
Whatever it is, it doesn't look like a dumb box.
Google suggests that the WK-3801W does wifi.
If your WK-3801A is similar, it looks like a modem/router. (I can't find anything about the WK-3801A.)
I'm probably missing a lot here. Your initial message is kind of hard to follow. Not least the layout of the network.
What order are all these boxes in?
The country code conflict is displayed in the extract of the log from the Mac Network Diagnostics utility which I enclosed in my post.
The router got the 10.0.0.1 address from Netgear's genie setup. It saw that the ISP connection box had an IP Address of 192.168.1.1, which is why it changed its own IP address from that to 10.0.0.1, to avoid a conflict - this is also explained in Netgear's documentation as a possibility.
Yes, the default IP address of the little fiber optic connection box is 192.168.1.1. and the box itself is just 2.5"x2.5"x1'' in size - it has no radios etc, just a power light, an internet light, a traffic light, one LAN port and an optical cable input. This was provided by the ISP and is the Gateway for the network.
Aplologies if I confused you. Here is the order of the things:
Fiber Optic cable (from ISP) to the "Little Box"
R7800 Router connected to the LAN port of the Little Box, via the Router's WAN port
TP-Link access point connected to a LAN port of the Router
TP-Link Powerline extender connected to a LAN port on the router
TP-Link 8 port gigabit switch connected to a LAN port on the Router
KuWfi Bridge connected to the Gigabit switch
Hope that explains thIngs a little better!
A couple of off the wall questions. What do you have configured for your NTP server? Are you using the default Netgear NTP server that is most likely in China? Look under Advanced -> Administration -> NTP settings.
Overall, how many devices are connecting back to your R7800 for IP addresses via the DHCP pool?
I configured NTP to pool.ntp.org - approximately 14 devices are connecting, although several of those I have assigned static IP addresses to

Yes. The layout makes sense now.
"Little Box" > R7800 (WAN) > TP-Link EAP110 > The rest (Powerline and switches)
But this still puzzles me:
Yes, the default IP address of the little fiber optic connection box is 192.168.1.1.Not something I would expect of a standard ONT. And I am not making that up:
Correct answer: Community Forums - Does an ONT Have an IP Address? - Verizon Community
Solved: FTTP - does the ONT have an IP address? - BT Community
Unfortunately, I am stuck in the coper cable era, so that takes ONT well outside my territory.
The country code conflict is displayed in the extract of the log from the Mac Network Diagnostics utility which I enclosed in my post.
I missed that in the formatting of the earlier messages.
Yup, I am likewise puzzled! I am looking at the "little box" now and there is a label on the bottom of it with its default IP of 192.168.1.1 and the usual username and password defaults.
The only other anomaly I have found is the "slave" unit of the KuWfi bridge has a strange IP address and is apparently acting in DHCP mode. Its IP address is on 192.168.0.0 and I'm not sure where that comes from if my network is 10.0.0.0?
I have the Fing Network Scanning App and it gives me a warming that DHCP is not healthy. (see attached screenshot) The Bridge has its own SSID, so I am not sure how that would affect the dropped connections on the other networks
