Setting up wifi system

[car10002]

Hi everyone

Wish to setup a wifi system sort of a mesh system like the motels and shopping centres do where they have more than one access point on same network, password, everything.

With that setup when you go from one area to other it switches from one access point to other seemless without messing anything up or videos and downloads restarting and you don’t know it’s just switched over

Also it has one wifi name for 2.4g and 5g

What would be the best way to go about that.

Will probably have atleast one access point in house, one in back room, one outside and one in each shed.

There are those ceiling points and there are those mesh systems and there are routers that work as one mesh.

Could you plug a router into the existing nbn modem and run all points off that and leave the old wifi settings as they are in the current modem, will the new setup mess up the old wifi settings.

Just wondering and thought there might be computer people on here that might know.

Thanks
