Nighthawk RAX70 extremely high ping only toward wifi-connected devices
Hi!
We use our AX6600 WiFi Router (RAX70) for a local network, which is not connected to the internet. We don't have a second router on the network. Currently, it has two connected devices via ethernet, and three via Wifi. All of them have static IPs. We tried Linux, Windows, iOS and Android devices.
We experience a problematic high ping (up to 300 ms, although 1% of the time you do see a 2 ms one, average ~80 ms) specifically only when pinging a device on Wifi, which is not the router. It does not matter whether the device we ping from is connected over ethernet or Wifi.
We experience normal ping (~1-3 ms) when
- pinging any device connected via ethernet, even from a Wifi connected device
- pinging the router from a Wifi connected device
The slow speed is also visible when sending data witch `scp` towards a Wifi connected device, reaching only a data speed of 70Mbps.
We tested this with no other devices actively streaming on the network. We tried different positions of the devices connected via Wifi and different positions of the router in the room. We tried connecting the router to internet. We updated the router to the newest firmware (now 1.0.15.146). We analyzed and changed Wifi channels. Nothing changed.
Do you have any ideas how to further troubleshoot or fix this?
Any help is greatly appreciated!

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.What channel configurations are currently set on the router?
Smart connect enabled or disabled?
How are you checking for ping with wireless devices?
Try disabling the following and see:
Armor, Smart Parental Controls or Circle, Traffic Meter.Be sure to disable any MAC Address randomizers on phones and pads while at home:
https://community.netgear.com/t5/Nighthawk-App/NETGEAR-Mobile-Applications-and-Apple-Devices-FAQ/td-p/2220015/jump-to/first-unread-messageHas a factory reset and setup from scratch been performed since last FW update?
Thank you for the fast answer! Unfortunately, I only today had access to the setup again.
We are in a office building, therefore I don't know what modem it is connected to. Because we only need the local network, we have (now) disconnected the router from any modem, but also tried it with modem connected and the same settings options. We have observed the same problematic behavior in all cases.
Current Channel Configurations are:
2.4 GHz: Channel 15 GHz-1: Channel 56, but on the Advanced webinterface status page, it says 52+56(P)+60+64
5 GHz-2: Channel 112, but on the Advanced webinterface status page, it says 100+104+108+112(P)
We have tried it with and without Smart Connect, no difference.
Parental Controls/Access Control and the Traffic Meter are switched off.
We can't access the Armor Settings (in the app or via 192.168.1.1) - on the status page underneath the big "A" and Security, it says "STATUS: NOT ACTIVATED". Also on the webinterface, under Advanced -> Security, there is no option for Armor. We assume Armor is switched off due to the router not connected to internet/a modem?
To ping, we do `ping 192.168.1.xxx` in the Terminal/Cmdline (have tried pinging from Windows and Linux). For our applications, the important recipients of this ping run linux (a mobile robot), but we have observed the same behavior (long ping only towards wifi devices) with android and ios phones with known, unchanging IP addresses.
Yes, we have done a reset (with the button in the back) since the FW update.
Are there any more things we can try to debug more in depth?
