RAX120 Wi-Fi connected but no Data transfer randomly

[xuzhe]

RAX120 happend on 108, 114 and 118. 

Situation:

After client devices (AC devices, not AX) wake from sleep, the Wi-Fi is showing connected but there is no data transfer at all.

The client device cannot access to neither the Internet nor local network, even to the router itself.

Renew DHCP infomation from device side not working too.

By login into RAX120 from other device, checked the "Attached Devices" list, the device having problem are not listed there.

The only way to recovery it is turn Off and ON Wi-Fi on the client devices.

For now, it seems disable ODFMA feature can fix the problem.

But I still want this feature for my other AX devices.

I am not sure if it's a known issue to Netgear, and if anyone else having the same problem?

P.S. I've tried factory reset the router, but still having this problem.

There is a discussion here that may help you.

Thank you for your reply.I've saw your reply on that discusstion before.

I've also noticed if disable OFDMA, everything seems OK just as what I said in my post above.

But here is a hope if netgear can fix/improve their OFDMA funciont so old diveces like Macbook Pro 2018 can access the Wi-Fi 6 router while some new Wi-Fi 6 devices can still get benefit from OFDMA.
