Questions about Netgear EAX15 WiFi 6 Mesh Extender

We will be going to a 1000 Mbit solution in February and will get it fed via the local TV network. As a result of the layout of our flat, we need a wifi repeater in the bedroom, is this product the fastest solution for this, or are there better ones in the digitec range?

Is it possible to install several (at least 2) Netgear EAX15 repeaters to improve the signal in several parts of the house? Not necessarily in cascade but simply on opposite sides of the router.

Does the repeater also work with the Swisscom Internet Box 3? Even without a cable connection?

Is the amplifier compatible with a netgear orbi wifi ?

Is this product suitable as a satellite for the Netgear ORBI RBK20 Mesh System?

Can this product extend the Arlo signal? Because Arlo is quite a scandal. It works for a 50 m2 garden. But if you're looking for something bigger, don't bother. I read on the internet that Netgear would be compatible with the very specialised protocol (which doesn't work with most other mesh or extender products).

Can we connect the Sunrise router to this Extender by cable, then disable the router's wifi to use only the Extender's? Thank you.

The Nighthawk app cannot connect to the mesh extender, it reports that it does not support the detected EAX15 extender, even though the Netgear homepage lists the device among the supported devices. It also does not recognise the QE code of the packaging, so I tried a manual connection. I am connected to the NETGEAR-EXT WLAN. Do you have a tip for me. Thank you Christof

I have tried several times to set up this extender with our Sunrise WLAN, but without success. Has anyone had a similar experience?

Is this extender EasyMesh capable?
