Hi Guys,

so, I'm looking for a wifi extender and i thought that i could buy a powerline that would extend my wifi, since I already have a Powerline system (This one), but only for ethernet cable (I use it to connect my PC to an ethernet cable since it is too far from the router). 

My question is, can I buy just the powerline WIFI passthrough (like this ) or do I need to buy the Kit?

Thank you in advance,

Ricardo
