      You can, of course, run an IPSec VPN on every node over wired Ethernet too which would be nominally more secure than PowerLine, but no one does that and it's not all built in for you.

        How is the encryption they implement between the two adapters a VPN?

        I just realized... maybe the confusion is that you don't know that adapter to adapter encryption is just a way of saying "VPN"?

          Yes, I thought VPN was a specific mode/role, not all point-to-point encryption.

            Dang, here's some info:
            http://www.cise.ufl.edu/~nemo/papers/ISPLC2007_AV_Security.pdf

            One of the things I never even thought of was that the system could be compromised if an attacker came into your house and paired their own Powerline adapter with your encryption key.

            But that would mean they would have to be in your house and also have access to your other adapters. And still that would only give them access to the network itself.

            Physical access trumps everything anyway.

              Pretty much always.

                Yeah, of course that could be done. But if they were in your house and you had Ethernet, they'd just plug in and that would be far easier.

                  The question is....

                  • How do we know that the signal stops at the meter?
                  • Could the people next door be connecting too?
                  • What about the power company?

                  I use and trust powerline networking. Great for a apartment, where you don't want to run cable, etc.

                    I just run the cabling anyway. I have a full network rack in my living room above my TV.

                      It doesn't. The signal goes all the way to the transformer (weather it's a useful signal or not.)

                      • Could the people next door be connecting too?

                      Possibly.

                      • What about the power company?

                      Almost definitely.

                      I use and trust powerline networking. Great for a apartment, where you don't want to run cable, etc.

                      I'd trust it as well, so long as the encryption is turned on.

                        @travisdh1 @aaronstuder What about speed though? I always thought it was super gimped and should only be used in situations where wireless can't be used but you can't run cabling at all.

                          speed is awesome these days. better than wifi by a mile

                            Crazy. Back in the day it was awful. I've never needed to research it for any company I've ever worked for so I sort of forgot about it/ignored it. Interesting to hear.

                              Yeah that was my impression too, but I tried it out recently and it's gotten way better. I tried these out and home and they are fantastic:

                                The speed was a downside to the tech in the first couple of years after it was released. You can reliably get 500Mbps connections now (making sure you're on the same leg of the breaker panel). While it's not gigabit, that is really impressive for pushing data over power lines.

                                The downsides are large with powerline. Like I said before, the speed is only good when they are on the same side of the breaker panel distribution. The other leg will often be very slow and barely usable. The other downside is that the nature of the tech is that if you do proper power filtering you kill performance, so the devices are relatively short lived.

                                If you need it, those problems are a small price to pay.

                                  $40? That's a much better price than anytime I had looked at those things.

                                    yeah and you can just add as many as you need to make your house one big hub. Plug one into the router, then one in any room that you need a drop.

                                      At that price put a couple right beside the main power panel. Being me I'm not afraid to add an outlet or two and actually get it done properly.

                                      I wonder how most properties ever passed inspection

                                        They've been pretty crazy fast for years now.
