[Since there's only one place to put model, etc., here's the info for the Deco S4 Version 2.0 - don't know more than that as I haven't opened the box yet!]

Ideally I’d like to turn the MR6400 into a modem and disable its router functionality, but I can’t see an option to do that. Would turning off Wi-Fi, NAT and DHCP achieve the same effect and allow me to use the primary Deco as a router instead?

If not, it appears that the way forward is to turn off the Wi-Fi on the MR6400, connect the primary Deco via an ethernet cable to one of the MR6400’s LAN ports, and then configure all the Decos in Access Point mode.

Which Is the best thing to do? Or is there some better plan!!

I’d also prefer to keep my laptop hardwired, it’s currently ethernet connected to the MR6400 – should I leave it connected to the router, or to the second LAN port of the primary Deco? I guess that if I turned off NAT and DHCP on the router then I would need to connect it to the Deco.

Thanks, Graham
