Wi-Fi ping spikes every 10 seconds.
Ping jumps from around 5 ms to 100 ms every 10 seconds.
The issue is reproducible only when connected via Wi-Fi. When connected to the router with an Ethernet cable, the problem does not occur. Resetting the router did not help.
Steps to reproduce:
1. Connect to the router via Wi-Fi.
2. Start pinging any external service.
3. Observe the ping behavior.

The router shows strange behavior that may be related to DHCP, DNS, or client state handling.
Devices often cannot connect to the router even when the Wi-Fi password is correct. Restarting the affected devices usually does not help. The issue is resolved only after rebooting the router.
One Tuya-like IoT device shows a specific case: if it is connected to the router and the router is rebooted, the IoT device can no longer reconnect until the IoT device itself is restarted.
Most other affected devices are iOS/macOS devices. For example, if a device is connected to the router and then its network settings are reset, it can no longer connect to the router, even though the Wi-Fi network is still visible in the list.
The same issue can happen after resetting network settings on an iPhone, reconnecting to Wi-Fi, and then changing Private Wi-Fi Address from Rotate to Fixed.
Cloud Gateway Ultra also shows that even when the affected device is not actually connected to Wi-Fi, the router still displays one or two phantom devices in the list of connected clients. These devices appear to have failed to connect in reality.
It looks like the router keeps some stale client state and then does not allow the same device to reconnect. Rebooting the router clears the issue.
Steps to reproduce:
1. Connect an iOS/macOS device to the router via Wi-Fi.
2. Reset network settings on the device.
3. Try to reconnect to the same Wi-Fi network.
4. Alternatively, on iPhone, reconnect to Wi-Fi and change Private Wi-Fi Address from Rotate to Fixed.
5. Observe whether the device can connect.
6. Check the connected clients list in Cloud Gateway Ultra.

Does same thing happen if the RS is in router mode?
Wondering if some odd issue maybe happening while in AP mode.
Are they getting connect with wifi and not getting an IP address or just not getting connected at all?
If you reset the network settings on the device then this wipes out the configured connection with the wifi system and will need to be re-connected to the system. Will not reconnect if the settings are cleared. This would be expected behavior. Network resets on devices should only be used in last resort for troubleshooting purposes.
My iphone 17 Pro Max connects fine to my RS600 and RS700 when they are online. Though my RS is in router mode. I can try AP mode as well and see if this happens.
What device are you using to ping the router?
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Is this the Cloud Gateway Ultra?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
Using ISP Detected DNS or custom DNS?
Is IPv6 Enabled or disabled?
Which ISP are you connected with?
Be sure to disable any MAC Address randomizers on phones and pads while at home:

Router: NETGEAR RS300
* Mode: Access Point mode
* Gateway/router upstream: UniFi Cloud Gateway Ultra
* ISP: Telia Sweden
* Firmware: 1.0.6.16
* Device used for ping: MacBook Pro M3 Max
* Ping test: ping google.com
* Test location: sitting approximately 30 cm from the RS300
* IPv6: Enabled
* DNS: Cloudflare DoH
all CAT6A - but it should not be a reason since there is no issue via cable to router
I heard it might be WIFI QoS that by some reason still enabled even in AP mode but it's still strange that it makes such a huge spikes
What happens if you ping the routers IP address from your Mac?
If your pinging thru the RS then thru the ISP Gateway, you could see odd spikes.
What happens if you ping directly at the gateway with your WiFi device with RS turned OFF?
And you do have the gateways WiFi disabled as well?
What channels are you using on the RS router? Try 1 and 40 or 11 and 48.
How is AP mode configured on the RS router? Dynamic or Static?
Answering to Ping topic(don't know why connection issue was added as a reply, created a separate topic for it)
"If you reset the network settings on the device then this wipes out the configured connection with the wifi system and will need to be re-connected to the system. Will not reconnect if the settings are cleared." - yes, then you fill the password and getting a message that the device can't be connected to the router
