I have successfully added a spare BT Hub 3 as a wireless access point to a Business Hub 5 using Powerline ethernet adaptors.
To avoid drilling through a 3' thick loose stone wall I now want to add a second Hub 3 to connect wirelessly to the First Hub 3 ( Wireless access point ) and then on through the powerline adaptors to the Hub 5 and the internet.
just joined this forum so may have missed previous answer to this
Any pointers greatfully received.
Thanks
Tim
