Hi, apologies as I am sure similar questions have been asked, but wanted to confirm whether there had been any significant changes.
In short, I have BT Whole Home setup with 6 discs covering a large area (~10,500 sq ft) including outbuildings, however maintaining the wireless connection between 2 of the discs has been problematic so I wondered whether it was possible to setup the furthest disc in the garden office with an ethernet backhaul connection to the disc in the garage.
I do not want to drill holes to connect the garden office back to the hub in the house, so backhaul off another disc is preferable.
Thanks
Depending upon which variant of the Wholehome discs you have, you can only connect either one or (at most )two of them direct to the hub, all other discs must be connected either by wi-fi or by daisy chain using the LAN port as you describe.
