I just bought an Airport Extreme router, that I want to connect to my Zyxel P-2812HNU-F1 modem/router to replace my wifi network. Currently, my Zyxel modem/router provides internet access through wifi and ethernet cables. I am going to buy a Synology NAS to use for file sharing and for time machine backups of my Mac Book Pro. Should I connect the NAS and/or the other ethernet cables for wired internet access to my Zyxel modem/router and only use the Airport Extreme for wifi (I believe that's called bridge mode?) or should I switch off (I would not know how exactly) the router function of my Zyxel (and only keep the modem function) and use the AE as my router instead? Thank you so much for helping me - a networking newbie - out!
