Need help setting up Deco Mesh Network (Beginner)

[mr_amz]

Hello, 

I have bought the Deco Home Mesh Wi-Fi 6 System (AX3000 Deco X55) as I have blackspots around my house where the router struggles to reach.

The vodaphone router I have is the THG3000 and the speed I have is 900 mbps.

I have never set up a mesh network before and would appreciate a thorough walkthrough including what to do in the router settings.

Thanks

@mr_amz  There are video and PDF guides here https://www.tp-link.com/uk/support/download/deco-x55/

Thanks for this, this is helpful. 
My main issue of help is to do with the Vodafone back end settings (i.e. converting the router into the modem)

@mr_amz  The THG3000 router does not convert into a modem. You should check whether the X55 connects directly to the ONT box. You will need your credentials from Vodafone. If you search this forum other Deco models have been connected, so the details should be closely similar.
