Am I using my TP Link WiFi extender correctly?

[Aprisa]

Just changed from Sky to Plusnet and lost the booster from Sky.

Bought a couple of TP link extenders which setup fine and I have my PC connected by cable to one of them.

The other is because one of my wireless cameras has a very weak connection so I wanted to help this, and boost connectivity in my workshop in the garden.

Problem is that each booster seems to create a new wireless network with .EXT on the end on the network, so I have Plusnet, Plusnet.EXT and Plusnet .EXT.EXT

This means that the camera will not in effect be on the same network as the others? as the cameras need to all be on the same network to be seen on the same screen what do I need to do?

Thanks
