I just installed a Sierra Wireless AirPrime MC7710 n my x86_64 based LEDE router.
I followed the guide I found here:
https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle
It did not help anything
Problem is that it does not appear to find a driver for it, see output at the end of my message
I also tried installing
kmod-usb-serial-sierrawireless
kmod-usb-net-sierrawireless
Did not help either, still driver is not found
