Compatibility: BT Mini Connector with BT Broadband Extender 600 kit?

[eman1001]

Hello, I have a BT mini connector kit set up in my house. One connected to my router, one connected to my BT TV box.

I need to connect two computers to my ethernet network but additional BT mini connectors are £90, whereas BT Broadband extender 600 kits are £30. 

Would I be able to connect a new 600 kit up to my pre-existing BT mini connecter kit to provide ethernet? Are they, or other powerline adapter kits compatible with the BT mini connector?

Thanks
