Apologies if this is in the wrong thread/post...

I'm looking for a way to remotely or schedule a reboot of my TP Link wifi adaptors/extenders (model AV600) - due to them dropping signal or getting into a state requiring a restart.

Neither the TP-Link PLC utility app or http://tplinkplc.net/ (web access) seem to allow me to do this - or it will only restart the 'local' adaptor that the device is connected to (and not all devices on the network).

I could be wrong, but I've seen some threads that give me the impression that I may be able to do this using the Kasa app - however I'm struggling to get the app to recognise my extenders... is this because they are not compatible? ... is there ever likely to be a firmware update which will allow this? 

Or do I need to purchase new Kasa compatible extenders? (hopefully not)

Alternatively any advise anyone has to help resolve my ask would be appreciated.

Many Thanks

Peter
