The RouterOS IPv6 support is not enough for me, so I need Linux kernel 4.x functions. The OpenWRT 18.06.2 use Linux kernel version 4.9 or 4.14.
I found a list, which devices are supported: https://openwrt.org/toh/start?dataflt%5 ... D=MikroTik
How do I install OpenWRT?
How do I reinstall the RouterOS if I don't like it? How do I save the original license key? Other important?
