Hi,
I've had my R7800 for about a month now.
I just started noticing this week that it's dropping ethernet connections, all of them. I've been able to recover by rebooting the router. I have two linux servers connected to the router by ethernet and one printer. In attached devices, when this problem occurs, it only shows wireless connections. The LEDs for the ethernet ports on the router are on for those connections, but I cannot ping or ssh into those linux computers until I reboot the router
I was reading this thread on the netgear forum and sounds like same thing I'm seeing. I'm hoping I don't have a bad router. https://community.netgear.com/t5/Ni...-keeps-dropping-Ethernet-devices/td-p/1263954
anyone else experience this and found a solution? I've tested using ping 1472. Adding +28 to that gives me 1500 and that is what MTU is set to in WAN settings. Maybe I'll try lowering it anyway, to see if it fixes this. Weird that it just started about 4 days ago and has happened twice in that time. I may also try an open source firmware. Worst case, I will have to install DD-WRT and setup an auto reboot nightly or ssh into DD-WRT on a schedule basis to 'shutdown -r now' or something like that
Thanks

I haven’t run into this issue as I have a ReadyNAS 524X and Arlo Base station/Orbi connected to it without issue.
I need further details like any settings you changed from default in LAN/WAN etc.
As for Open Source you are better off with OpenWRT especially hnyman’s build as they are usually more stable than DD-WRT overall and seem faster with fixes. Most important OpenWRT has SQM QoS functionality which is amazing.
Hnyman updates master and stable builds every few days:

Thanks, It's all pretty much vanilla plain setup. I've disabled upnp and ipv6. I don't have any static routes. I have a few port forwardings and some reserved DHCP ips. Of the reserved IPs, # 1, 2 and 4 in that short list are those that are connected via ethernet and are the ones dropping off occasionally (only happened twice so far in the month or so I've had it, but all in the last 4 days). Yeah, if you see anything weird that might explain this behavior let me know. Thanks

Also OpenWRT has dreadful UI - it seems as someone with utter contempt for people who refuse to do things via command line was forced to make a UI and that how LUCI came to be.
Setting up VPN in OpenWRT for example is a nightmare - list of things that are wrong with it merit a separate article while in DD-WRT a chimpanzee trained to use CRTL+C and CTRL+V can do it in seconds.
I am pretty good with these things, if I may say so myself, and even I have trouble with some things on OpenWRT, so while in OpenWRT one can theoretically do anything it's damn complicated to do and by recommending it you're risking the fact that someone will end up hating youVasudev, alexhawker and Aivxtla like this. -
Yeah that's why I recommended hnyman's build which have most things integrated, but I get where you're coming from. Maybe I need some more haters
. I consider my self a novice really learning more from other users lol, so if someone like you who is used to using CL is saying that, its pretty scathing for OWRT lol.
On a side note, Hnyman was also pretty good about putting info/scripts for newcomers on his build site on creating their own builds, which I managed to ad extra stuff thanks to a GUI component and compile but yeah it was an interesting experience, let's just say I will stick to pre built OpenWRT firmwares, takes so long to compile lol, especially because I used a Linux Mint VM on Windows. From what I hear DD-WRT is a bigger nightmare for compiling.
@ygohome, can you try deleting all your reserved IPs and simply adding reservations client side? It may be a bug with the reservation function on the router, I think I deleted my reservation for my NAS and put the reservation on the NAS itself, last time something like this happened now that I recall.Last edited: Jul 17, 2018ygohome likes this. -
Thank you. I'll try the setting of static IP address on the two linux servers in their /etc/sysconfig/network file instead of letting the router reserving the IPs. For the printer I'll connect HP printer by usb to the router instead of ethernet, frees up a port that way too.

Just quick recap on how the R7800 is working as I forgot to follow up regarding the issue I was having back in July 2018 with dropped connections. Well, it was a long time ago but it somehow resolved itself without me having to much. I kept the factory firmware intact. In other words, I didn't switch to OpenWRT or DD-WRT. I think all I did was deleting reserved IPs and re-adding their reservations. I also set the clients themselves with static IPs in their OS. That later is probably what corrected it.
Anway, I'm writing here today to say I've upgraded from 1.0.2.52 to latest 1.0.2.62 Netgear firmware today. I did this to solve an openvpn issue that was corrected in the later build. The problem I'm now having is that I cannot use 5Ghz frequency band if HT160 is enabled, so I disabled HT160. I'm not deeply concerned about that feature though.
Other than the HT160 having to be disabled, all is working great with this R7800 router and openVPn is working too. Very happy.
