I have installed LEDE 17.01.2 on miwifi mini, and the package kmod-rt2800-usb (with his dependencies).
When I plug the wifi adaptor+antena to the ruter it has a kernel error and reboot. Before install the latest stable version of LEDE, I have installed one trunk of January of this year were everything works perfect. Is the package kmod-rt2800-usb broken?
Tis is the Kernel log:
