Thanks for confirming. I'm an existing customer but as everything in the house has been stripped down, the old BT socket has also made it to the skip.
So as an update summary, the Cat 6 cables will be installed on Monday. The patch panel and basic switch will reside in the loft and cables run down to all the rooms (2 per room). I will use the supplied BT Smart Hub 2 for now. ONT will also be in the office.
After reading back on this thread, I will use UniFi AP (with the UniFi Cloud Key Controller) mounted on the landing ceiling. Now speaking to several people they say go with a couple of the UAP-AC-LITE, one on each floor (I live in a standard 2 storey house with a rear extended kitchen).
Do I need one for the hall ceiling too? I don't know whether something like one UAP-AC-LR or PRO will suffice in the landing but I'm told that the more expensive APs cater for more connections to the AP rather than strength.
I'm more inclined to just add one to the hall anyway as once the carpets are down in the landing, I don't want to lift them up again to feed an ethernet cable! Am I going overkill here? Shame I can't test the strength of one AP just in the landing!
