Dear guru,
I am using version 18.06.2 r7676-cddd7b4c77 / LuCI openwrt-18.06 branch (git-19.020.41695-6f6641d) on Netgear WNDR3700. With many custom packages and settings. Could you please advice the best way to upgrade my router to the latest available firmware preserving all that settings.
Thanks in advance,
Vadim
