Hi, i need some advises. I'm not really good at networking stuff.

I am currently using Unifi's router d-link dir-x1860z. and i wished to connect it with Deco X20.

If i bought a 2-pack Deco X20, do i need to use a node as a Mesh router and put it beside the d-link dir-x1860z, and then i got 1 unit left as a node?

Please help to clear my confusion on my above doubt. Thanks! 

just get rid of the dlink and use the 2 packs of deco

one of the deco will act as router + main node, then the 2nd unit can be placed somewhere else

Do you mean I dump the dlink router and get the one of the deco and configure it as router?

Read this, then you will understand what is mesh, and do you really need it at home
