hi it is me again, i did what you said but also fixed the maximum MTU number to 1472 and it seems to help, now is dropping internet in some certain pages only ( maybe dns ipv6 problem?), also it kinda fixed cloning the mac adress from the internet router to the R3 router, it might seem that the internet provider wanted me to use their router not any other router and they were disconnecting my internet conection at certain times of the day ( or at least thats what I think), now I only have the problem that after a few hours the internet stop working on some internet pages like reddit o x.com, but it doesnt happen over wifi when using their native app, it only fails in my computer browser ( I tried brave edge and chrome with no succes) any suggestion?
