I already have a TP-Link AV2000 Ethernet network going strong in my home, and we want to add WiFi Powerline extenders. Since we will not need the direct connection to the router (existing network and all), is it possible to use BOTH units the adapter with the plug and single Ethernet port from the TL-WPA8631P as separate range-extenders on the network (i.e., anywhere in the house)? Or would I be buying the kit only to be unable to use the adapter with the single Ethernet plug (the one in the kit meant to plug directly into the router)?

We just need to know how this works. Buying a kit with two adopters and only being to use one would really suck. Thanks, everyone for your help!
