We purchased a NETGEAR® Insight Managed WiFi 6 AX6000 Tri-Band Multi-Gig Access Point (WAX630) a few months ago and ever since we installed it we've been getting disconnection issues when users connect their mobile devices to the AP. 

It's not consistent as iOS and some Android devices can maintain a connection. But some such as a Galaxy-S10 as a token example can only connect for sometimes a minute before it disconnects and attempts to reconnect. 

AP's firmware is V10.8.6.3 which I know isn't the latest. We'll be trying a firmware upgrade a the end of the week but I've seen elsewhere that this issue has existed on this AP since version 10.7. 

An example of what I've seen in the diagnostic log for just one device:
