Hello,
Here's my situation. I have a Home Hub 4 and many devices connecting to it. On Friday, I expect to receive a Home Hub 5. On Tuesday, a BT engineer (hopefully proper Open Reach, as I see a lot of their vans around here) will activate Infinity 2, pop round and install the data extension kit with new cable.
I take it there's nothing to stop me (i.e. no property specific config on the device) simply swapping in the Home Hub 5 on Friday, and getting all our devices working with it?
