YouFibre

If they are using DHCP might need the lease to be released or wait for it to expire to switch to a new router. Would expect if you were on to support they would have released it manually or told you the expiry time. Spoofing the mac address would get round that aswell.
Their DHCP lease time is only an hour apparently :P used to be 7 days but they reduced it for "various network side factors" they told me. (I had a separate issue with something and support mentioned that!)
 
Not sure how I'd spoof MAC on ASUS ET12, will take a look.

I turned off the router/ONT for a couple of hours early and problem persisted

Certainly nothing wrong with connection, just plugged eero back in and worked straight away!

So to me it now seems to be 2 outcomes

1. ASUS ET12 is borked out of the box (unlikely)
2. There is some kinda lock on the MAC of eero to Static IP

@HEADRAT Unlikely related but since YouFibre probably have older ET12 stock they won't have upgraded firmware. Asus over the past 2 months have been udpating routers due to a massive vulnerability allowing anyone to infect their router with malware, take down the wifi radios etc. Threads at SNB: https://www.snbforums.com/threads/malware-damaging-asus-routers.92752/

Do not connect the ET12 to the internet. Go here on the Eero: https://www.asus.com/uk/networking-...elpdesk_bios?model2Name=ASUS-ZenWiFi-Pro-ET12

Grab 3.0.0.4.388_24610 firmware then only connect the ET12 to a PC with LAN. Upload that firmware to the Asus and flash. Atleast this way if the engineer does fix it your ET12 won't automatically be infected with malware. You kind of dodged a bullet by it not working tbh.

First thing I did was update firmware, level 1 made me setup static IP through router interface, it should have been just DHCP, what a waste of time I’m ******!

There is.
Static IP gets locked to your router MAC and if you plug a different router in you need support to refresh the MAC lock their end.
Doesn’t happen on dynamic IP but static your connection won’t work until it sees the MAC it expects or you get them to reset and lock to your new one.
 
Yup, that and the ASUS ET12 need to be set to DHCP rather than have the WAN details set manually via the UI

IP
Subnet
Default Gateway

as instructed by their tech.
