Hello everyone, first i don`t speak english, I want to change the original hotspot template for a custom html with a script so that I can execute commands inside the mikrotik, can it be done?

Hi, i update my SXT SQ lite 5 to this new version, i use in ethernet ARP ¨reply-only¨ and i have problems, random clients lost the acces for long time, is random ... i put ARP to ¨enable¨ and all is ok ... in other versions of routerOS i don´t have this problem ...
