The TP-Link Deco M4 or M5 is a doddle to set up via their App according to my 2 non-techy mates who recently got them. Make sure what you get has GB ports.
Just need to use the correct sequence - whatever you choose do this
________________________________________________________
Disconnect all cables from your new router (or Mesh first unit) and unplug it. Put the VM Hub into modem mode (see VM website for “how to” details) and wait for the base light to turn magenta/purple (on a Hub3 - but not on a Hub4!). Once it’s in modem mode, the VM hub must then be powered off. Then, set up your own router/Mesh with the WAN port set to be in DHCP mode, it may be pre-set that way anyway. Make sure it’s fully initialised (leave 5 min) and then put in the WAN cable to the VM hub. Now power up the VM hub and you should get a connection. Use the recommended App to connect other Mesh units to the first one. This order only needs to be done the first time you connect the router to the VM hub.
