00:00:07,759 --> 00:00:13,679
as awesomely convenient as wi-fi is it

4
00:00:11,440 --> 00:00:18,880
certainly isn't without its shortcomings random dropouts crummy speeds and

5
00:00:15,839 --> 00:00:21,119
limited range are all potential problems

6
00:00:18,880 --> 00:00:24,320
especially if you live somewhere with thick walls or lots of interfering

7
00:00:23,199 --> 00:00:28,560
signals i mean you could just run Ethernet

8
00:00:27,119 --> 00:00:33,680
cables everywhere but that can be a messy solution and uh

9
00:00:31,439 --> 00:00:37,760
good luck suing yourself for pain and suffering when you trip over one on the

10
00:00:35,760 --> 00:00:41,280
way to get a g fuel refill in the middle of the night

11
00:00:39,200 --> 00:00:47,039
but what if i told you an elegant way to solve this problem is

12
00:00:44,000 --> 00:00:49,360
already built right into your house even

13
00:00:47,039 --> 00:00:53,920
if you don't have a newfangled home with Ethernet outlets in the walls

14
00:00:51,280 --> 00:01:00,399
i'm talking of course about power line adapters devices which send data signals

15
00:00:57,440 --> 00:01:03,120
over your home's electrical wiring it's like whoa

16
00:01:01,920 --> 00:01:07,439
dude like isn't all that copper wiring in

17
00:01:05,119 --> 00:01:09,439
your walls busy carrying you know like power

18
00:01:08,640 --> 00:01:15,119
well great question surfer Linus it turns out

19
00:01:12,320 --> 00:01:22,240
that like sound pitch or the frequency of a wi-fi band ac power has its own

20
00:01:18,720 --> 00:01:24,479
waveform with a frequency of 50 or 60

21
00:01:22,240 --> 00:01:28,720
hertz depending on where you live so power powerline Ethernet works by

22
00:01:26,880 --> 00:01:33,040
simply sending signals through your wiring at very different frequencies

23
00:01:31,360 --> 00:01:40,159
with modern implementations of the technology between 2 and 86 megahertz

24
00:01:37,520 --> 00:01:45,600
kind of like how dsl internet provides high speed internet access over the same

25
00:01:42,880 --> 00:01:49,040
wiring as your landline phone by using a different frequency you can learn more

26
00:01:47,600 --> 00:01:54,240
about that up here and although electrical wiring in your

27
00:01:51,040 --> 00:01:56,000
house connects lots of different devices

28
00:01:54,240 --> 00:01:59,119
instead of being a strictly point-to-point connection like

29
00:01:57,360 --> 00:02:04,719
conventional Ethernet power line adapters have internal logic

30
00:02:01,920 --> 00:02:09,599
that allows them to catch the signal kind of like your smartphone or laptop

31
00:02:06,880 --> 00:02:13,840
can catch a wi-fi signal that spreads out in all directions

32
00:02:11,840 --> 00:02:17,440
well that's great and convenient in all Linus but how fast is it

33
00:02:16,640 --> 00:02:24,640
well although the theoretical maximum of the newest revision of power line is about

34
00:02:21,760 --> 00:02:30,080
two gigabits per second your real-world performance will probably top out at

35
00:02:26,480 --> 00:02:32,560
around 100 to 200 megabits although this

36
00:02:30,080 --> 00:02:37,120
is still definitely fast enough for high-speed internet browsing and even 4k

37
00:02:35,040 --> 00:02:43,599
streaming and from my personal experience it comes with a consistency

38
00:02:39,760 --> 00:02:46,319
and latency advantage over wi-fi

39
00:02:43,599 --> 00:02:51,840
now with all that said if the wiring in your house is older or not the best

40
00:02:49,280 --> 00:02:57,200
quality or if you are trying to place two adapters very far from each other

41
00:02:54,400 --> 00:03:02,319
your speeds might drop well below 100 megabit due to signal degradation so i

42
00:03:00,400 --> 00:03:06,800
recommend buying your first couple of powerline adapters from a retailer with

43
00:03:04,400 --> 00:03:10,239
a solid return policy before making a full commitment

44
00:03:08,239 --> 00:03:13,840
there are also a few caveats to keep in mind when setting up a home powerline

45
00:03:12,239 --> 00:03:20,000
network whatever you do plug your adapters

46
00:03:16,319 --> 00:03:22,720
directly into the wall devices like ups

47
00:03:20,000 --> 00:03:27,280
battery backups power conditioners and surge protectors can mis-identify your

48
00:03:25,760 --> 00:03:33,200
data signal as undesirable electrical noise and

49
00:03:30,000 --> 00:03:35,440
actually filter it out also be sure to

50
00:03:33,200 --> 00:03:40,720
follow the instructions provided for securing your powerline network with a

51
00:03:38,000 --> 00:03:44,480
password especially if you aren't living in a fully detached home

52
00:03:42,799 --> 00:03:49,519
just like your neighbor can easily access your wi-fi network if it's not

53
00:03:46,480 --> 00:03:52,000
password protected anybody who shares an

54
00:03:49,519 --> 00:03:56,879
electrical circuit with you even through a breaker panel can possibly get into

55
00:03:54,400 --> 00:04:01,040
your power line network this is a common problem in apartments

56
00:03:58,879 --> 00:04:06,400
lastly if you're looking to optimize your speeds try different combinations

57
00:04:03,439 --> 00:04:11,519
of outlets if possible some work better than others and high draw devices like

58
00:04:08,879 --> 00:04:16,799
microwaves on the same circuit can actually cause slowdowns and remember

59
00:04:14,000 --> 00:04:22,479
that less is more for powerline because running many many adapters can cause

60
00:04:19,199 --> 00:04:24,160
network congestion similar to old-school

61
00:04:22,479 --> 00:04:29,919
Ethernet hubs and sadly there's not a quick

62
00:04:26,240 --> 00:04:32,880
over-the-counter pill that can fix uh

63
00:04:29,919 --> 00:04:37,680
network congestion speaking of slowdowns wouldn't it be

64
00:04:34,800 --> 00:04:42,080
great to travel with fewer slowdowns check out away luggage they cut out the

65
00:04:40,320 --> 00:04:47,199
middleman to bring you premium quality suitcases at lower prices not only do

66
00:04:44,880 --> 00:04:51,520
they offer their suitcases in four sizes they all come with the same great

68
00:04:53,280 --> 00:04:59,120
your gadgets charged when you're traveling whether you're filming on

69
00:04:56,639 --> 00:05:03,440
location like me or you know doing something

70
00:05:00,400 --> 00:05:04,800
more cool or less cool they've got 360

71
00:05:03,440 --> 00:05:08,880
degree spinner wheels so you can navigate the airport with ease and a

72
00:05:07,039 --> 00:05:13,199
compression system that allows you to fit all the spare socks and sandals that

73
00:05:11,120 --> 00:05:17,680
you could possibly need away luggage suitcases are also theft resistant with

74
00:05:15,280 --> 00:05:22,080
tsa approved combo locks built in and are made with impact resistant german

75
