Just tried new openwrt-ar750s-3.100-1122. I have checked Keep All things in Update so maybe that’s the cause but LuCI does’nt appear anymore like in the last previous firmware. Installed LuCI from WebUI but nothing and Advanced menu is not there even after installed LuCI. If manually try to get into LuCI page in Firefox,(erased cache all clean) only WebUI opens (http://192.168.8.1/#/ only)
BUT I have seen new good features like Tor VPN and Killing Internet if VPN not working option (among other things I don’t remember).
I wait for other comments here.
