Cisco Linksys Powerline Network Adapters

This ethernet network adapter system contains 1 four port PLSK400 adapter, and 3 single port PLEK400 adapters. Use your homes existing electrical powerlines to transfer network traffic. It works great for getting an ethernet signal to an area of your house where wifi cant reach, or a landline ethernet line doesn't exist. First hard wire the 4 port adapter with an ethernet cord to your router and plug it into a nearby outlet. I have a few extra short ethernet cords if you need them. Then take the sattelite adapters and plug them into an outlet where you dont have signal and want to, and boom you have a hard wired ethernet connection. I have used this system for years in my home and it has worked flawlessly for streaming Prime and Hulu video to a tv in my basement, and transferring data from my security system DVR in the shop. We recently upgraded our entire wired network system in our home and we no longer need them. Please don't low ball me, I think these are selling for my asking price for 1 unit, and this is for 4 of them. Thanks for looking.
