I'm pulling out my hair trying to get OpenWRT running on my 3B+. Everything it good except I cannot get my Trendnet TU3-ETG (asix-ax88179) to show up in interfaces on openwrt web interface. I've tried installing every package that people have said to install related to USB ethernet including the kmod-usb-net-asix and specifically asix-ax88179 Rufus MapQuest UpToDate
. I do get an error saying can't satisfy dependencies related to the kernal version. Per the openwrt website I forced it and it seemed to install but the dongle doesn't show up in interfaces. I think I came across one suggestion that said to re-compile openwrt with the driver installed but I'm not sure how to do that.
