as awesomely convenient as wi-fi is it
certainly isn't without its shortcomings random dropouts crummy speeds and
limited range are all potential problems
especially if you live somewhere with thick walls or lots of interfering
signals i mean you could just run Ethernet
cables everywhere but that can be a messy solution and uh
good luck suing yourself for pain and suffering when you trip over one on the
way to get a g fuel refill in the middle of the night
but what if i told you an elegant way to solve this problem is
already built right into your house even
if you don't have a newfangled home with Ethernet outlets in the walls
i'm talking of course about power line adapters devices which send data signals
over your home's electrical wiring it's like whoa
dude like isn't all that copper wiring in
your walls busy carrying you know like power
well great question surfer Linus it turns out
that like sound pitch or the frequency of a wi-fi band ac power has its own
waveform with a frequency of 50 or 60
hertz depending on where you live so power powerline Ethernet works by
simply sending signals through your wiring at very different frequencies
with modern implementations of the technology between 2 and 86 megahertz
kind of like how dsl internet provides high speed internet access over the same
wiring as your landline phone by using a different frequency you can learn more
about that up here and although electrical wiring in your
house connects lots of different devices
instead of being a strictly point-to-point connection like
conventional Ethernet power line adapters have internal logic
that allows them to catch the signal kind of like your smartphone or laptop
can catch a wi-fi signal that spreads out in all directions
well that's great and convenient in all Linus but how fast is it
well although the theoretical maximum of the newest revision of power line is about
two gigabits per second your real-world performance will probably top out at
around 100 to 200 megabits although this
is still definitely fast enough for high-speed internet browsing and even 4k
streaming and from my personal experience it comes with a consistency
and latency advantage over wi-fi
now with all that said if the wiring in your house is older or not the best
quality or if you are trying to place two adapters very far from each other
your speeds might drop well below 100 megabit due to signal degradation so i
recommend buying your first couple of powerline adapters from a retailer with
a solid return policy before making a full commitment
there are also a few caveats to keep in mind when setting up a home powerline
network whatever you do plug your adapters
directly into the wall devices like ups
battery backups power conditioners and surge protectors can mis-identify your
data signal as undesirable electrical noise and
actually filter it out also be sure to
follow the instructions provided for securing your powerline network with a
password especially if you aren't living in a fully detached home
just like your neighbor can easily access your wi-fi network if it's not
password protected anybody who shares an
electrical circuit with you even through a breaker panel can possibly get into
your power line network this is a common problem in apartments
lastly if you're looking to optimize your speeds try different combinations
of outlets if possible some work better than others and high draw devices like
microwaves on the same circuit can actually cause slowdowns and remember
that less is more for powerline because running many many adapters can cause
network congestion similar to old-school
Ethernet hubs and sadly there's not a quick
over-the-counter pill that can fix uh
network congestion speaking of slowdowns wouldn't it be
great to travel with fewer slowdowns check out away luggage they cut out the
middleman to bring you premium quality suitcases at lower prices not only do
they offer their suitcases in four sizes they all come with the same great

more cool or less cool they've got 360
degree spinner wheels so you can navigate the airport with ease and a
compression system that allows you to fit all the spare socks and sandals that
you could possibly need away luggage suitcases are also theft resistant with
