So have recently moved to use Openwrt on my raspberry pi 3 b. I am looking to use it for hotspot tethering to ethernet. I found documentation on how to connect my phone to the pi, I have no issues with that. However, for my setup, I need to use a Realtek RTL8153 USB to ethernet adapter. When I connect the dongle it appears when I run "lsusb" over ssh but doesn't appear under interfaces in the web UI or when I create a new interface. I found a forum post that was related to this however it doeset provide any instructions on what I need to do to solve the problem. https://forum.openwrt.org/t/adding-usb-network-adapter-was-openwrt-18-06-1-on-raspberry-pi-3-model-b-rev-1-2/30577/2
Thanks in advance!
