No, but with the Swisscom box and also with Sunrise with a Fritz router.
With the Fritz router, it works very well and is pleasant to use with all the router functions.

On the other hand with the Swisscom Box, the basic functions also work, but there is no interest since it is incompatible with the rest of the functions. It must be the same with a Salt box, since you need setting pages on the box that are dedicated to the Fritz brand.
Too bad
