It cuts down a lot of BS on the phone support lines when you use the correct terms and can have a sensible go at diagnosing the issue.
We dont use the CPE term often in the UK. It’s modem ONT router etc.
Have a look on www.bidb.uk and see what comes up.
It does support failover. It’s in the manual.
Right ???
I think the easiest thing to do would get a used 5G hub from the likes of fleabay, setup the BSD box for link fail over. What distro are you using ?
For double NAT issue getting a real IPV4 address is a chew using regular data Sims. The only one I’ve had long term success with is 3.
Sorry, I’m assuming your UK based ?
I’m one of those people into Omada. Yes it’s not sleek and shiny like unifi but it does an incredibly similar job for a cheaper price. Reliability has been very good for me. No returns or issues yet 🤞
For you I’d start with https://www.tp-link.com/uk/business-networking/omada-router-integrated-router/er7212pc/ it can easily be hidden away.
Add a https://www.tp-link.com/uk/business-networking/omada-wifi-ceiling-mount/eap650/
And / Or

And your away. Add another any APs you need to the POE switch on the router.
If you want recommendations on a switch let us know how many ports you need.
Your just pissing cash in the wind buying ancient HW like that. Why are you so keen to get WRT ?
That’s not a bad speed for copper tbh. Have a look on www.bidb.uk and see what comes up. If you need any advice just holla at us.
You don’t want traffic flowing across the router so stick to 1 wan 1 Lan and let the first switch figure it out. You could go either :
Modem - Router - Small switch - “Floor” Switches. Or Modem - Router - Poe Master Switch.
I’d stick to having a larger switch and running cables back to it into a patch panel or 2. But it’s a case of what’s going to be easiest for you.
