Hey @ninnella, that'd be your best option.
By white adapter, I presume you're talking about the D-LINK Powerline adapters?
I use this set up at home and it works flawlessly.
One white adaptor is connected to your modem (via the Ethernet port) and plugged into a nearby power-point. This adaptor converts the broadband connection from your modem so it can be sent through your electrical wiring to a second power-point to which the other adaptor is connected.
If you have any other questions, let us know.
