I bought a AC750 wireless repeater, but I don't need the repeater functionality.

I've got a TP Link 5 port wired switch plugged into it, so I can use the AC750 as a wireless bridge, allowing me to have a 4 port wired switch in my home office and then a wireless bridge (via the AC750) to my router downstairs.

I therefore don't need any wireless repeating and would prefer to switch it off to remove the unessesary re-broadcasting. I cannot see the option in the control panel to disable rebroadcasting the signal, does any one have any advise how to do this?
