As the router has been factory reset you won't get internet through it until the Setup Wizard has been completed so if you do get internet through it that indicates it's not working as it's acting like a switch. When did the issues first start, after rebooting, resetting, changing settings etc?

Hi all,
So I want to purchase a R2.
I currently have a Superhub 4. And I want to put that router into Modem/Bridge mode and then connect the Netduma R2 to it instead. BUT. My house got renovated a few months ago and in that process we ended up getting these installed on 3 levels of my house: They're called Ubiquiti access points. Now I don't know much about these but here is a link: https://www.amazon.co.uk/Ubiquiti-UniFi-Lite-Access-Point/dp/B08T6CKG5B. I'm not sure if it's exactly this model but it looks like that.
Now, what I do know is that my wiring is like this currently:

Superhub 4 > TP Link 5 Port Gigabit Desktop Switch (model TL-SG1005p) > D-Link Ethernet Port Hub (model DGS-108) > Lots of Devices
The D-Link Ethernet Port Hub basically will have a LOT of Ethernet wires connected to it. I have the PS5, the Laptop, Smart TVs, 3 Ubiquiti Access Points, Chromecast, 2 Sky TVs and other stuff. Literally the only WIFI we have is 2 mobile phones.
So now I want a Netduma, and I have a few questions:
Firstly I want to know if the Netduma works well with Virgin/Superhub 4? Did it make your experience better or worse or the same? Honest answers please!
Secondly, I literally want the Netduma just for the OS. I'll obviously slot the Netduma in between the Superhub 4 and the TP Link 5. And then to be safe, I'll plug PS5 via ethernet straight into the Netduma. Everything else will be laid out the same. So if I buy a Netduma R2 and set it up, is everything else still going to work fine? I'll want everything that's wired connected to the Netduma R2, and the two mobile phones connected via WiFi to the Ubiquity Access Points. Is that ok?
I want the Access Points working the same as intended. I'll hate it if I buy the Netduma and now the 'wifi has gone off around the house' I'll get a yelling at from every family member.
Thank you!
