how can i achieve this?
recently i moved to another country and i started to have issues with the internet (need VPN for almost everything), so i've been digging on network stuff trying to figure out how to make things work but i'm not happy with my current set up (second attached image)
that's why i come here with my questions..
for context: i have ZERO knowlege of programming or network stuff. i'm a ui designer with passion for movies so that's what keeps me going on setting this up. i learn fast and i have some notions about how things work but i'd like to ask: what should i learn/study to achieve my desired setup? (first image attached)
i work 7 days a week so i only have 1-2 hours to study before going to work, that's why i want to know what exactly i should look for. i have asked AI, but it just gives me a step by step process on how to make it and i don't want to follow instructions without knowing what am i doing
my ideal set up would be to have all my smart speakers (alexas) and ipads connected on the same network with a streamlined OS so i could talk seamesly to all of them, and at the same time control the smart devices on the house (2 tvs). the OS on the ipads should be able to communicate to the other devices (notes, alarms, commands).. i have seen the home assistant projects but idk how to implement it here..
thanks so much for any help in advance
