@gattiamare To whomever that find themselves in the same situation... I reinstalled the drivers of the wireless devices on my laptops (upgraded if possible). After that I found that Deco emitted...

@woozle Yep, I tried this. Unfortunately it did not solve the issue.

The more I look into this, the more I realize that this is, indeed, due to the laptops WiFi devices not being compatible with WiFi 6. There seems to be no other drivers for them, so I guess I'm stuck?

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...
