An alternative solution to the tethering limitation is to use a usb-c to ethernet adapter. I use a wavlink 2.5 GBe device. This solution  however requires, that I buy another thingye to make my network setup complete. I still think that providing usb-tethering on a product in this tier would be a requirement of a networking device in 2024/2025 era. The Asus I referred to in the beginning of this post is/was (it's old) a significantly cheaper product.

Hello, I've been searching for this as I'm considering getting the BE550 to replace old Asus router I'm currently using spare 5g phone connected via usb to Asus to gain internet access, it's a shame as the spec and price seems reasonable for BE550 , I'll look into usb c - ethernet adapter 

Thanks

My usb-c to ethernet adapter seems to be working flawlessly. However you are introducing a potential security risk in your networking pipeline. So be sure to verify that the item you add is indeed a simple network-adapter and not a full fletched soc in disguise. I have had no issues with mine.

I probably hold off for the time being, Asus ax88u still working great , I'll be getting dedicated home broadband soon , the 5G was temporary but it's great feature to have as I might need it in the future hope tp link could add this in firmware update because the all round spec and price looks good
