Thank you for your reply Chewitt.
This hotspot would for example allow say an iPhone in that room access to the fibre network via said hotspot through to the LAN as if the phone was a wired device?
Edit: the phone is in fact the only Wi-Fi device that I’d like to grant ‘better’ access to my network, the walls in my house are stone and thick enough to make it connected but weakly. I understand the warning about (even if I used same ssid and password) it wouldn’t transition seamlessly and whilst this is a shame it’s not a problem (to be honest maybe better as then I could use a separate ssid and password)
To be honest this would be an extra value thing to save the bother of building a Mesh
