Converting a range extender system to seamless coverage

[Boucks]

Hi,

I have a BT Smart Hub 2 and three TP Link extenders. The extenders are all hard wired and connected via a switch to the router. Each of the extenders share one password and the coverage is excellent but I want to create a seamless system without removing any of the extenders. Any suggestions?
Regards,

Chris

Suggestion? Ask on the tplink forum and not the netgear forum?
We're going to steer you towards netgear gear/setup versus your tplink setup.

Fair play... shows how much I know on the subject and the desperate help I need (not just on this subject, clearly)!
