anons, i need some advice in regards to my new home network
ive moved to my new home, and finally got the internet working
i have two routers, one is my own and another one is from the internet provider ( tp-link archer be3600 and a Zyxel VMG8825-T50K, also have an old tp-link tl-wr841n )
what is the best way to to connect it all together, so i have good wi-fi connection around the house?.. what should i plug "in the wall" first - Archer og Xyxel? Should i run "bridge" connection on the second router and connect it to the first one via LAN cable? Is it possible to connect both routers via wi-fi, without losing too much connection speed? ( i would rather not drill any holes for the network cables, unless its absolutely necessary )
any general tips on setting up a home network? any links to a good online guide covering such task?
all help would be appreciated! thank you anons!

tl;dr
what is the best way to establish wi-fi, having my own tp-link archer be3600 and a Zyxel VMG8825-T50K from provider?
