Fiber (separate modem and router)

Strange question maybe...

I currently have a fiber connection with Leucom, which has served be very well, but there are cheaper options available now.

The thing is that they have a very nice hardware setup: a fiber model (fiber to ethernet WAN) and a separate router + wireless access point.

This is great because I have the modem in a wall cabinet, which contains also ethernet ports to all rooms. So in the living room I have the router, which offers good wifi coverage there (+ a separate access point in the bedroom).

Is there any provider that offers the two pieces separately? I want to switch to Salt, but I fear that I will have their modem in the cabinet and poor wifi outside.

you buy a 2-piece mesh setup with ethernet backhaul. Nest Wifi, Linksys Velop, Netgear Orbi, all can do it.

most, not to say all modems can have a separate router connected.

You just have to buy it separately.

I don't understand the problem.

No problem if I buy it. I was thinking of using the one that comes from the provider, and in case of Salt it seems to be a single device (modem+router). In case of Leucom it is two separate devices.
