AC12

Hi everyone. First time here. but not my first time doing this networking thing. But for some reason i don't find what am i doing wrong... Recently i changed my access point router in my room from a mercusys ac1200 i think to an ax1500 so i could use the gigabit ports and have better wifi in my room The thing is, now im having problems everynow and then. I live in a third world country. all my devices have voltage protectors but when power goes off (none turns off when that happens) but i lose connection in the access point that i use in my room to connect to my pc and have wifi. To solve it i have to basically factory reset the ac point. but when pówer goes off again so does the internet capabilities of my AP I have a router right next to the fiber optics modem in my living room and that one has no internet issues at all. its just the one in my room, i run a cable around the house so i can connect my living room router directly to the AP Router in my room. Does anybody know why would this happen? i swapped the operation mode for the one in my room to AP mode but i think something's missing... I remember i had to manually change the ip type to static in the old one but i don't remember exactly what i had to do and for some reason i don't find the source of that info anymore... Also if i connect the cable directly to my pc ( the one running from the living room ) i don't have any connection problems at all
