I setup my Deco X50 with the following properties:

• 2.4GHz --> ON
• 5 GHz --> ON
• SSID + password
• WPA3-Personal + WPA2-PSK [AES]
• "Hide this network from Wi-Fi lists" --> ON
• Channel Width for 5GHz --> 160 MHz
• Advanced settings are untouched so far, so eg. "Fast roaming" is disabled
• ... and a guest network

It works flawlessly with phones and some other peripheral devices, but when I try to connect my laptops to it, they can't connect.

I have already tried the obvious stuff, like restarting the routers and laptops, forgetting the SSID and try reconnecting. The drivers for the WiFi are updated to the latest versions on the laptops.

I can connect to the guest network, no problem.

I can also connect if I disable 5GHz, however, this unhides the network for some reason, and as soon as I hide the network again, it disconnects the laptops. It only seems to affect the laptops. The phones and everything else continues working throughout this process.

Does this have anything to do with some WiFi 6 black magic and that some devices can't utilize this when hidden or something? This would be a 100% deal breaker for me, as we now have three laptops without WiFi in the house and I need my SSID to be hidden.

Please advice me on how to solve this issue.

Worth nothing is that this worked without any issues at all on my previous TP Link Archer C9 (just moved to a big house and needed mesh so I changed to Deco X50)

Update: It seems the Deco is emitting "Hidden Network", and if I connect to that (I have to enter both SSID and password) it does connect, but after I restart the laptop, it's gone again.
