no Repeater mode? RAX49 routers (house-to-house wifi)

While I have not use the RAX49 specifically, I have used the RAX50 and RAX45, and a few others in the AX line. They have been making some UI changes, thus some will have a dedicated UI option to simply switch to it a wireless bridge. while other models have it buried in a submenu where you have to go to the web UI > Advanced> Advanced Setup> Wireless Settings> check the box for "use other operation mode", and then you can set up the wireless bridge.

One annoying limitation that wireless bridge mode disables the AP functionality of the router, even though it is only using one of the radios for the backhaul, and there is nothing really stopping them from adding an option to use the other WiFi radio as a single band AP, e.g., if you use the 5GHz radio as a backhaul, then allow the 2.4GHz radio to still work as an AP.

Beyond that, the wireless bridge functions are quite good, especially in terms of performance since unlike normal where you will have a WiFi router with a 990milliwatt transmit power, and a smartphone with a 50-100milliwatt transmit power, you have devices on both ends will higher gain antennas as well as a better transmit power, thus they can maintain a stronger connection, better PHY rates, and fewer corrupt frames.

The Netgear range extenders are more purpose built for this use case and for both their newer WiFi routers and extenders, but on both cases, they use pretty high end radios and RF front ends on them, thus receiver sensitivity is really good.

The main thing I see lacking with Netgear's product line, especially for your use case,is a lack of consumer point to point directional units, thus you often see people gravitating towards things like the Ubiquiti nanobeam products for point to point since they will maintain a higher PHY rate over those distances, purely due to the high gain directional antenna.
