RS600 Shows false negative (Blocked) Devices
For years we have had a network that comprises of a gateway on the ground floor and an Access Point on the 3rd level that connected to the ground floor by cable - we control the access to the Interne...

I don't have the router, so I can't try to reproduce your symptoms.
If I am understanding your symptoms correctly, then the problem devices are all connected via the AP (whether RAX50 or RAX40). Is that correct?
If so, I am wondering what happens if you connect the problem devices directly to the RS600.
Also, do both the RAX50 and the RS600 have the same network name and password?

With great respect, you started that sidebar with your earlier reply.

Just to make sure that the problem does not come from the Access Point, we put the RAX40 back as Access Point and got the same behaviour
The first Access Point you talk of is the Wi-Fi of the RS600?

It looks to me the OP Jacob_of-Aus has re-added RAX40 in AP mode to isolate the RS600 Wi-Fi part - operating as a kind of Access Point - direct on the router.
And the issue is the same in my reading: The RS600 router appears not working correctly, regardless of the wireless devices are connecting direct to the RS600 Wi-Fi or the RS600 LAN.

Agree the RS600 is the router. The way I understand the first post is that Jacob_of-Aus has always had a router+AP setup. That was RAX50 (router) and RAX40 (AP).
Then he upgraded to the RS600, so the configurations that aren't working are the RS600 (router) + RAX50 (AP) and also RS600 (router) + RAX40 (AP).
I am thinking he went back to the RAX40 as the AP to rule out the RAX50 as the problem. I don't see anything about the RS600 wifi - whether that the RS600 wifi is turned off, or whether the AP network has the same name as the router wifi or not.
I agree that the RS600 router appears to be the problem, but thinking that connecting the problem devices directly to the router would be a useful test. From the first post, it looks to me like the problem devices are all connected to the AP. But I am not certain of that, so wanted to confirm.

My apology if I did not explain my problem the properly.
Firstly, we are a small, 30 Suites on 3 levels private hotel with about 40 devices (give or take) connected to the Internet at any one time. As residents (guests) pay for Internet connection by device. We use ACL to control access in addition to password for obvious reasons.
On the ground floor we have is RS600 as gateway router (connected by cable to the modem that receives Internet from the ISP).
On the 3rd level we have RAX50 configured as Access Point (AP) and connected by cable to the RS600.
(Please forget about the RAX40, it was put in temporarily just ensure that problem does not come from RAX50. Once we established that indeed the problem comes from RS600, the RAX50 was reinstated. In other words, our?network comprises of 2 routers only, RS600 and RAX50.)
The RAX50 is configured as Access Point (AP) to avoid maintaining 2 ACLs. The only ACL we have resides in the RS600.
We have only one password for both routers for convenience reason.
Due to the topography of the building approximately 1/3 of the devices connect only to RS600, 1/3 connected only to the RAX50 and the balance 1/3 can connect to either of them. All connections are wirelessly.
The firmware on the RS600 is V1.0.6.22
The Problem
The problem manifests itself mainly with latest devices or better said with device that have the latest WiFi cards such as iPhone 16 and newer, iPad 11 generation and later, latest Android and Windows devices.
1. Devices that connect to the Access Point (RAX50) shows on ACL as Blocked and connected to the RS600 on both 2.4G and 5G channels. Repeated amount of trying to change their status to Allowed, come back as Blocked.
2. Looking at the Attached Devices list of the RS600 shows those blocked devices as connected to the RAX50 (as a wired connection) and Allowed.
3. Some, but not all do have Internet connection (hence the caption False Negative), others do not have Internet.
4. Sometimes we can overcome the problem by turning off affected devices, remove them from ACL manually add their respective MAC addresses to List of allowed devices not currently connected to the network. Whilst such workaround produces the intended result, some devices still get blocked by the system after a while, which is extremely frustrating.
We also noted that the reponse of the Access List has been slowed down dramatically in recent times. In the past any change to access list was instantly reflected on screen which is no longer the case:
When we add an allowed device manually, we no longer see the changes reflected the allowed devices not currently connected to the network list, when we try to enter it again, we get message to the effect that This MAC address is already on list, or words to that effect.
When we delete one or more devices from the Blocked Devices Not Currently Connected to the network list the access list come back with all the deleted devices still on it. We must repeat the deletion or to refresh the ACL a few times before changes are reflected in the list.
Whilst originally, we took it as a behaviour of the RS600. today we discovered the same behaviour in our other much smaller private hotel, with only one router, RAX50, that cover the whole house. Such behaviour is consistent with updating a distant database, such across the Pacific Ocean, as it is from where we are, in Sydney, Australia, to somewhere in USA.
What gave you done, Netgear?
Go n Figure that :-(
