 Welcome to another Linksys Powerline unboxing. This is slightly different from the one that we saw before. So there's two versions of the PL something 400. There's the PLSK 400, which has the one with one port and the one with the four port hub built in. And there's also the PLEK 400, which just has two 200 megabit per second powerline adapters and neither of them has a four port hub or switch or whatever you want to call it. It's more of a switch than a hub built in. Okay, so what does Linksys have to say for themselves? Transfer speeds up to 200 megabit per second. It should be noted that most powerline kits are not, even whatever they're rated at, are not capable of exceeding 200 megabits per second anyway. So Linksys' claim is that their spec is a very honest spec, if nothing else. Okay, even if it's not the best spec. Plug and play, easy setup, I can attest to that. Push button security, which you don't even have to use, you just plug them in and they go. Fast ethernet ports. I think by fast they mean 10 hundred, which by today's standards is not that fast, but neither is Powerline when you compare it with gigabit ethernet. So it's not really fair. Powerline is the technology that if you don't already know and you don't follow this channel and you don't know how much I love Powerline, it allows you to run networking data through the copper wiring that provides electricity to the various parts of your home. So you take this, you plug it into the wall, preferably where there's an outlet and not here, and then you have an ethernet cable that runs either to your router or to some other networking device, whether it's a smart TV down in your media center or whether it's a computer that's in the attic and is otherwise very inconvenient to access with straight networking cable. Comes with everything you need, including two ethernet cables, which you plug into there and then plug into the other thing that you want. So the networking happens between these two. Actually this is the best illustration I can think of for Powerline, because it basically works like this. These guys interpret the data that runs along, I can never remember, eight pins here, turns it into two pins here, then there's some copper wire in between, and this guy interprets it on the other side for eight pins to be compatible with pretty much any network adapter anywhere attached to a device. So there's the button that enables the security, there's your gigabit ethernet or gigabit, 10 hundred ethernet port, there's your power indicator, there's your network indicator, and there's your other more different network indicator for the other more different network that is running on here.
