1
00:00:06,750 --> 00:00:08,250
- [Dave] Hey, everyone Dave here.

2
00:00:08,250 --> 00:00:12,300
This video is about network
interface card configuration.

3
00:00:12,300 --> 00:00:14,520
And so I'm gonna show
a couple things here,

4
00:00:14,520 --> 00:00:16,080
kind of move around a little bit.

5
00:00:16,080 --> 00:00:19,980
We're gonna show a connection
of a laptop's wireless card

6
00:00:19,980 --> 00:00:24,090
to a Soho router wireless access point

7
00:00:24,090 --> 00:00:25,800
that we set up previously,

8
00:00:25,800 --> 00:00:27,660
and then we'll show some of the settings.

9
00:00:27,660 --> 00:00:31,410
And then we'll take a look at
a wired network interface card

10
00:00:31,410 --> 00:00:32,520
from our main system

11
00:00:32,520 --> 00:00:34,740
and show some of those settings as well.

12
00:00:34,740 --> 00:00:37,980
So what we have here is I'm working at

13
00:00:37,980 --> 00:00:40,898
the Windows 10 Pro laptop.

14
00:00:40,898 --> 00:00:45,030
And down here, we have
the icon for wireless.

15
00:00:45,030 --> 00:00:47,160
If we click on that, we'll see

16
00:00:47,160 --> 00:00:49,261
that we have a connection right now

17
00:00:49,261 --> 00:00:51,000
to something called Unknown Network Five.

18
00:00:51,000 --> 00:00:53,320
And that's a different wireless network

19
00:00:53,320 --> 00:00:54,840
that I have running here.

20
00:00:54,840 --> 00:00:57,390
I also have that wired connection,
that ethernet connection

21
00:00:57,390 --> 00:01:01,524
with this patch cable
going directly to this.

22
00:01:01,524 --> 00:01:04,110
And I've got that multi IP,

23
00:01:04,110 --> 00:01:06,390
that multiple IPs set up on that

24
00:01:06,390 --> 00:01:09,240
that we did previously, but
I wanna connect this guy

25
00:01:09,240 --> 00:01:12,090
to this in a wireless fashion.

26
00:01:12,090 --> 00:01:13,500
And so we have two options for that.

27
00:01:13,500 --> 00:01:16,470
We've got the 2.4
gigahertz network we set up

28
00:01:16,470 --> 00:01:18,810
and the five gigahertz.

29
00:01:18,810 --> 00:01:20,070
And that's what I want

30
00:01:20,070 --> 00:01:25,070
because this has an 802.11
ACM.2 card in there.

31
00:01:26,490 --> 00:01:27,993
So let's click on that.

32
00:01:30,381 --> 00:01:31,731
And we'll click on connect,

33
00:01:33,180 --> 00:01:36,033
and we need to enter the security key.

34
00:01:41,280 --> 00:01:45,093
Okay, and we'll do that and click next.

35
00:01:46,290 --> 00:01:48,517
It verifies and connects.

36
00:01:51,341 --> 00:01:53,463
And we should get an IP address on that

37
00:01:56,070 --> 00:01:57,273
in just a little bit.

38
00:01:59,130 --> 00:02:00,580
There we go.

39
00:02:00,580 --> 00:02:01,620
Connected and secured.

40
00:02:01,620 --> 00:02:03,003
Let's take a look at that.

41
00:02:03,899 --> 00:02:05,880
We got a couple places
where we can look here.

42
00:02:05,880 --> 00:02:08,583
First of all, we can look here.

43
00:02:10,020 --> 00:02:12,720
We'll refresh our
network connection screen

44
00:02:12,720 --> 00:02:15,000
which is in the control panel.

45
00:02:15,000 --> 00:02:17,640
And it shows here we have that
ethernet wired connection.

46
00:02:17,640 --> 00:02:20,070
And here's that wifi connection

47
00:02:20,070 --> 00:02:22,143
now connected to EM-5-BACN.

48
00:02:23,700 --> 00:02:28,120
Yes, and if we go to our command prompt

49
00:02:30,420 --> 00:02:32,913
Clear it out, and we'll run an IP config.

50
00:02:35,520 --> 00:02:37,353
We'll take a look at what we have.

51
00:02:38,790 --> 00:02:41,940
Here's that wired
connection with the two IPs,

52
00:02:41,940 --> 00:02:44,490
and here's the wifi adapter.

53
00:02:44,490 --> 00:02:47,490
And it gave us the Soho router.

54
00:02:47,490 --> 00:02:51,840
The wireless access point
gave the laptop 10.252.25.150.

55
00:02:54,660 --> 00:02:56,250
So it chose to do that.

56
00:02:56,250 --> 00:02:59,580
Now, remember the network
we're on is 10.252.

57
00:02:59,580 --> 00:03:03,840
the last two octets could be
whatever this guy chooses.

58
00:03:03,840 --> 00:03:05,850
And so we can prove that,

59
00:03:05,850 --> 00:03:09,180
that we're on the same
network as that Soho router

60
00:03:09,180 --> 00:03:13,770
by doing a ping and
pinging that IP address,

61
00:03:13,770 --> 00:03:16,743
which is right here, 10.252.0.101.

62
00:03:21,570 --> 00:03:23,250
and press enter.

63
00:03:23,250 --> 00:03:24,633
And we get the replies.

64
00:03:26,610 --> 00:03:30,630
So we're in, and we can
look more at the adapter.

65
00:03:30,630 --> 00:03:31,920
If we go back to our network connections,

66
00:03:31,920 --> 00:03:33,780
we can right click on that.

67
00:03:33,780 --> 00:03:35,880
And, you know, we could
go to the properties

68
00:03:35,880 --> 00:03:38,070
and find out more about IP

69
00:03:38,070 --> 00:03:40,920
and anything that we
have installed for that.

70
00:03:40,920 --> 00:03:42,820
But we could also right click on that.

71
00:03:43,800 --> 00:03:48,750
We could go to the status
and see what we have here.

72
00:03:48,750 --> 00:03:53,260
We have internet access
through the Soho router

73
00:03:54,240 --> 00:03:57,810
and our speed right now is
at 433 megabits per second.

74
00:03:57,810 --> 00:04:00,990
That's an 802.11 AC connection.

75
00:04:00,990 --> 00:04:03,060
We can see here, we have full bars,

76
00:04:03,060 --> 00:04:06,434
but really it's the data
transfer rate or speed

77
00:04:06,434 --> 00:04:10,170
or throughput that we're
most interested in.

78
00:04:10,170 --> 00:04:14,433
And that's gonna settle at
433 megabits per second.

79
00:04:16,470 --> 00:04:18,570
We can also disable
this if we need to here.

80
00:04:18,570 --> 00:04:21,330
We can connect and disconnect
from wireless networks,

81
00:04:21,330 --> 00:04:22,620
bridge connections.

82
00:04:22,620 --> 00:04:24,540
If we go back to properties,

83
00:04:24,540 --> 00:04:27,780
let's say we want to
configure this a bit more.

84
00:04:27,780 --> 00:04:29,613
We can go to the configure button,

85
00:04:30,720 --> 00:04:35,430
and that'll bring up the
properties window for that device.

86
00:04:35,430 --> 00:04:38,523
You can also get to this
from the device manager.

87
00:04:39,540 --> 00:04:41,850
And so you can see here

88
00:04:41,850 --> 00:04:46,230
the device that's running,
it's an AC 3160 M.2 card

89
00:04:46,230 --> 00:04:48,753
that we saw physically
when we opened the laptop.

90
00:04:49,740 --> 00:04:51,330
And if we go to advanced,

91
00:04:51,330 --> 00:04:55,470
we'll see lots of options
here that we can work with.

92
00:04:55,470 --> 00:04:57,240
For example, the channel width

93
00:04:57,240 --> 00:04:59,193
that we have set up here for 5.2.

94
00:05:00,630 --> 00:05:02,070
We wanna have this set to auto.

95
00:05:02,070 --> 00:05:05,100
That's what the wireless
access point is set to,

96
00:05:05,100 --> 00:05:07,200
but you can change the width

97
00:05:07,200 --> 00:05:10,260
from say 20 megahertz to 40 megahertz.

98
00:05:10,260 --> 00:05:12,180
We're gonna leave that as auto,

99
00:05:12,180 --> 00:05:14,670
but a couple of things that
you wanna look at here.

100
00:05:14,670 --> 00:05:16,740
For example, transmit power.

101
00:05:16,740 --> 00:05:21,720
We can adjust the power
of the wireless antennas.

102
00:05:21,720 --> 00:05:24,000
And we said, you know,
we have the M.2 card,

103
00:05:24,000 --> 00:05:29,000
and it goes out and around
through here and up here,

104
00:05:29,910 --> 00:05:33,490
those antennas, we can
adjust the power of those

105
00:05:34,500 --> 00:05:38,370
between a value of one for
lowest and five for highest.

106
00:05:38,370 --> 00:05:41,670
Could be that we don't
need five, the highest

107
00:05:41,670 --> 00:05:44,310
especially because the laptop's
right next to the router.

108
00:05:44,310 --> 00:05:45,930
Well, it won't be later,

109
00:05:45,930 --> 00:05:48,030
but let's see what happens
if we change it to one.

110
00:05:48,030 --> 00:05:48,993
Click okay.

111
00:05:49,920 --> 00:05:52,710
Okay, it took a moment to reconnect

112
00:05:52,710 --> 00:05:54,990
cause we're changing the radio power.

113
00:05:54,990 --> 00:05:57,480
It's gonna identify and
try to reconnect to it,

114
00:05:57,480 --> 00:06:00,575
but I'll bet you it'll still be full bars.

115
00:06:00,575 --> 00:06:02,280
And let's take a look at the status,

116
00:06:02,280 --> 00:06:05,823
and it is the same because
of the proximity here.

117
00:06:07,211 --> 00:06:10,560
In some cases you may want to limit

118
00:06:10,560 --> 00:06:15,330
the wireless connectivity, the radio power

119
00:06:15,330 --> 00:06:20,330
because you may have a
concern about war drivers

120
00:06:20,520 --> 00:06:24,123
or people trying to access a laptop.

121
00:06:28,080 --> 00:06:30,180
But I'm gonna put that
back to five, the highest.

122
00:06:30,180 --> 00:06:33,240
You never know, you might
leave it as three, medium

123
00:06:33,240 --> 00:06:38,052
because these are pretty powerful radios

124
00:06:38,052 --> 00:06:39,000
that are in laptops.

125
00:06:39,000 --> 00:06:40,500
So you may wanna reduce that.

126
00:06:40,500 --> 00:06:42,303
And that could be company policy.

127
00:06:43,380 --> 00:06:46,590
You also have things like
wake up on Magic Packets,

128
00:06:46,590 --> 00:06:48,490
and that's part of wake on LAN

129
00:06:49,796 --> 00:06:53,455
So if some computer needs to
access data on this laptop,

130
00:06:53,455 --> 00:06:56,130
it could be woken up over the LAN

131
00:06:56,130 --> 00:06:57,757
via the bios or UFI.

132
00:06:58,770 --> 00:07:02,490
You have different wireless
modes that you can set up here.

133
00:07:02,490 --> 00:07:03,960
Roaming aggressiveness,

134
00:07:03,960 --> 00:07:06,690
how aggressive is this
wireless connection gonna be

135
00:07:06,690 --> 00:07:09,990
when it's looking for
a wireless access point

136
00:07:09,990 --> 00:07:12,063
which you may need to set to higher.

137
00:07:15,120 --> 00:07:18,690
The throughput booster
which can work to increase

138
00:07:18,690 --> 00:07:22,290
the data throughput rate
or the data transfer rate

139
00:07:22,290 --> 00:07:26,460
of a wireless network
adapter if it's compliance.

140
00:07:26,460 --> 00:07:28,740
There's a lot of options here.

141
00:07:28,740 --> 00:07:30,990
Okay, but basically what
you would do once again

142
00:07:30,990 --> 00:07:34,860
to get to that is you'd
right click on the card,

143
00:07:34,860 --> 00:07:36,750
go to properties,

144
00:07:36,750 --> 00:07:41,750
then go to configure, and
then you'd go to advanced,

145
00:07:42,270 --> 00:07:45,330
and you could make those
changes from there.

146
00:07:45,330 --> 00:07:49,870
And I'm gonna reset the
transmit power to highest

147
00:07:51,150 --> 00:07:52,290
and reset that.

148
00:07:52,290 --> 00:07:54,900
Now you can also go to the
control panel directly,

149
00:07:54,900 --> 00:07:56,940
and let's say you wanna
go to the control panel.

150
00:07:56,940 --> 00:08:00,030
You can go to the run
prompt and type control.

151
00:08:00,030 --> 00:08:01,320
You can also do it by, you know,

152
00:08:01,320 --> 00:08:04,140
going through the start menu and so on.

153
00:08:04,140 --> 00:08:05,460
And then from the control panel,

154
00:08:05,460 --> 00:08:08,740
we'd wanna go to our
network and sharing center

155
00:08:10,260 --> 00:08:12,783
and then go to change adapter settings,

156
00:08:13,744 --> 00:08:15,000
and you could get to it from there.

157
00:08:15,000 --> 00:08:17,460
Or you can go a little bit more direct

158
00:08:17,460 --> 00:08:19,020
and go to the device manager,

159
00:08:19,020 --> 00:08:21,690
which you can also get to
directly from the run prompt

160
00:08:21,690 --> 00:08:24,903
by typing devmgmt.msc,

161
00:08:26,250 --> 00:08:30,600
that's dev management, and
then find the network adapter

162
00:08:30,600 --> 00:08:34,710
in this case, the AC
3160, right click that

163
00:08:34,710 --> 00:08:36,180
and go to properties.

164
00:08:36,180 --> 00:08:39,210
And your advanced settings will be there.

165
00:08:39,210 --> 00:08:42,360
So different ways to get to
the same thing basically.

166
00:08:42,360 --> 00:08:45,210
And of course, be looking
in your command prompt

167
00:08:45,210 --> 00:08:47,610
to see all the data about that connection.

168
00:08:47,610 --> 00:08:49,830
And we only did an IP config.

169
00:08:49,830 --> 00:08:52,830
You could do an IP config slash all

170
00:08:52,830 --> 00:08:57,090
to find out more information,
and here's that wifi.

171
00:08:57,090 --> 00:08:59,730
You can see the IP address
that was handed to us,

172
00:08:59,730 --> 00:09:04,730
the subnet mask, and that
this is leased to us.

173
00:09:06,210 --> 00:09:07,450
This is a lease

174
00:09:08,464 --> 00:09:12,766
because it's given to us
by a DHCP server .101.

175
00:09:12,766 --> 00:09:15,780
That's the router, that's the Soho router,

176
00:09:15,780 --> 00:09:17,220
the wireless access point,

177
00:09:17,220 --> 00:09:18,720
which is also the default gateway.

178
00:09:18,720 --> 00:09:20,700
It is also the DNS server.

179
00:09:20,700 --> 00:09:22,620
You only see this additional information

180
00:09:22,620 --> 00:09:25,140
and things like the Mac address

181
00:09:25,140 --> 00:09:27,330
if you do an IP config slash all,

182
00:09:27,330 --> 00:09:30,150
and it tells us DHCP is indeed enabled.

183
00:09:30,150 --> 00:09:33,783
Yes, and this is the DHCP
server that gave us the address.

184
00:09:35,370 --> 00:09:38,128
For our ethernet adapter,

185
00:09:38,128 --> 00:09:40,710
DHCP is not enabled.

186
00:09:40,710 --> 00:09:41,940
It says no.

187
00:09:41,940 --> 00:09:46,607
We statically configured
those addresses here, right?

188
00:09:47,850 --> 00:09:49,980
And so to connect to wireless networks,

189
00:09:49,980 --> 00:09:51,270
you go to your icon here

190
00:09:51,270 --> 00:09:54,570
which if you only have
wireless, it'll look like this.

191
00:09:54,570 --> 00:09:56,160
If you only have a wired connection,

192
00:09:56,160 --> 00:09:59,430
it'll look like a little
computer or a port connection.

193
00:09:59,430 --> 00:10:01,410
And you'd right click on that.

194
00:10:01,410 --> 00:10:03,150
And you could go to network
and internet settings

195
00:10:03,150 --> 00:10:05,370
or you could just click on it

196
00:10:05,370 --> 00:10:08,133
to bring up those
networks that it can see.

197
00:10:09,120 --> 00:10:11,520
This is also where you
could set up a hotspot

198
00:10:11,520 --> 00:10:13,020
and set it to airplane mode

199
00:10:13,020 --> 00:10:15,453
to turn off our all wireless activity.

200
00:10:16,543 --> 00:10:18,960
If we right click and go to open a network

201
00:10:18,960 --> 00:10:23,960
and internet settings, you'll
see your actual connectivity

202
00:10:24,180 --> 00:10:26,130
from the computer to the wireless network

203
00:10:26,130 --> 00:10:28,860
out to the internet, shows
you what you have here.

204
00:10:28,860 --> 00:10:30,315
This is Windows 10,

205
00:10:30,315 --> 00:10:35,078
and you know in a control panel,

206
00:10:35,078 --> 00:10:37,930
you can also go to
network and sharing center

207
00:10:39,270 --> 00:10:42,150
to see that same type of information.

208
00:10:42,150 --> 00:10:43,800
So two different places to go.

209
00:10:43,800 --> 00:10:47,880
This is the new look for making
these configuration changes,

210
00:10:47,880 --> 00:10:49,530
but if you ever have to get more in depth

211
00:10:49,530 --> 00:10:50,820
with the configurations,

212
00:10:50,820 --> 00:10:53,460
then you'll end up in the control panel.

213
00:10:53,460 --> 00:10:56,523
For example, somewhere like
change adapter settings.

214
00:10:57,510 --> 00:10:59,790
Okay, so you wanna be able
to get around a little bit

215
00:10:59,790 --> 00:11:00,840
and be able to view

216
00:11:00,840 --> 00:11:03,336
how you can connect to wireless networks,

217
00:11:03,336 --> 00:11:05,730
how to view those wireless networks,

218
00:11:05,730 --> 00:11:08,310
how to use IP config and IP config/all,

219
00:11:08,310 --> 00:11:09,810
how to get to the advanced settings

220
00:11:09,810 --> 00:11:12,930
for the configuration
of the wireless adapter,

221
00:11:12,930 --> 00:11:13,830
all that stuff.

222
00:11:13,830 --> 00:11:17,880
And so now let's move
over to my main system.

223
00:11:17,880 --> 00:11:19,860
We'll take a look at a wired connection

224
00:11:19,860 --> 00:11:22,263
and some of the advanced
settings for that.

225
00:11:23,550 --> 00:11:26,040
Okay, so I've headed over
to my main system here,

226
00:11:26,040 --> 00:11:29,100
and this is the AV editor computer.

227
00:11:29,100 --> 00:11:32,910
It actually has two wired
network adapters, no wireless

228
00:11:32,910 --> 00:11:34,350
just two wired.

229
00:11:34,350 --> 00:11:37,440
And so to look at those,
we could do an IP config.

230
00:11:37,440 --> 00:11:38,700
We'll press enter,

231
00:11:38,700 --> 00:11:41,070
and we'll see a variety
of information here.

232
00:11:41,070 --> 00:11:43,530
Some of which I've shown before

233
00:11:43,530 --> 00:11:46,410
when we were doing some other work earlier

234
00:11:46,410 --> 00:11:47,490
in another video.

235
00:11:47,490 --> 00:11:50,340
So here is the main
network that I connect to.

236
00:11:50,340 --> 00:11:52,770
That's my main network
where I do all my work.

237
00:11:52,770 --> 00:11:56,870
You can see the IP network
number is 192.168.41.

238
00:11:58,770 --> 00:12:01,710
And this particular computer is 202.

239
00:12:01,710 --> 00:12:05,100
The default gateway is 192.168.41.1

240
00:12:05,100 --> 00:12:08,883
That's another router that
I'm connecting to there.

241
00:12:10,020 --> 00:12:12,150
Separate router altogether.

242
00:12:12,150 --> 00:12:17,150
Then I also connect from this computer

243
00:12:18,570 --> 00:12:23,570
with another ethernet adapter
to my dpro42.com domain

244
00:12:23,670 --> 00:12:28,440
which is that BACN network I
was talking about previously

245
00:12:28,440 --> 00:12:31,950
and using that 10.252 IP network number,

246
00:12:31,950 --> 00:12:36,547
and this particular
computer gets 10.252.0.254.

247
00:12:38,790 --> 00:12:43,650
And the default gateway
for that is 10.252.0.101.

248
00:12:43,650 --> 00:12:48,180
And that is that router,
that wireless access point

249
00:12:48,180 --> 00:12:49,950
that we were just showing.

250
00:12:49,950 --> 00:12:52,620
This way I can connect to
my test network as well

251
00:12:52,620 --> 00:12:54,900
with a second network card.

252
00:12:54,900 --> 00:12:56,972
And I have another IP here

253
00:12:56,972 --> 00:13:01,680
192.168.0.254 on this guy,

254
00:13:01,680 --> 00:13:03,330
which is what I use normally,

255
00:13:03,330 --> 00:13:07,860
that actually could create a IP conflict

256
00:13:07,860 --> 00:13:11,370
because that is the address
I used on the laptop

257
00:13:11,370 --> 00:13:13,560
on the wired side.

258
00:13:13,560 --> 00:13:17,370
It won't because there's no
central connecting device

259
00:13:17,370 --> 00:13:19,932
running 192.168.0,

260
00:13:19,932 --> 00:13:22,980
but still they're both
configured with that

261
00:13:22,980 --> 00:13:24,600
as a secondary IP.

262
00:13:24,600 --> 00:13:26,460
And I forgot I had done that here.

263
00:13:26,460 --> 00:13:28,710
So that's one thing I wanna change,

264
00:13:28,710 --> 00:13:32,010
but definitely be able
to do your IP config

265
00:13:32,010 --> 00:13:37,010
and also know how to do an IP config/all

266
00:13:39,553 --> 00:13:42,423
so that you can see more
in depth information.

267
00:13:45,150 --> 00:13:48,063
Like I say, you can see
if DHCP is enabled or not,

268
00:13:49,920 --> 00:13:53,640
the Mac address, the DNS server.

269
00:13:53,640 --> 00:13:56,160
It is not enabled on either of these.

270
00:13:56,160 --> 00:13:59,343
I'm running statically for
both of these connections.

271
00:14:00,630 --> 00:14:01,920
So you wanna be able to do that.

272
00:14:01,920 --> 00:14:03,270
You also want to be able to go

273
00:14:03,270 --> 00:14:06,723
to the network and sharing center.

274
00:14:07,740 --> 00:14:09,153
We'll bring that up here,

275
00:14:10,050 --> 00:14:11,610
and you could see my connections here.

276
00:14:11,610 --> 00:14:14,340
I have network and network two, right?

277
00:14:14,340 --> 00:14:15,660
One is called main network.

278
00:14:15,660 --> 00:14:17,670
One is called dpro42.

279
00:14:17,670 --> 00:14:20,400
Click on those to find
out more information

280
00:14:20,400 --> 00:14:24,150
or you can go to change
adapter settings to see those.

281
00:14:24,150 --> 00:14:29,150
And so for example, we could
go to say my main network

282
00:14:29,250 --> 00:14:31,773
and take a look at that, go to properties.

283
00:14:33,506 --> 00:14:35,820
We'll see all the different
items that are used

284
00:14:35,820 --> 00:14:36,960
by this connection.

285
00:14:36,960 --> 00:14:39,663
Most importantly, IP version four.

286
00:14:41,370 --> 00:14:42,600
And if we look at those properties,

287
00:14:42,600 --> 00:14:44,943
we'll see the IP address
that I added here.

288
00:14:45,810 --> 00:14:47,103
We can go to configure,

289
00:14:48,630 --> 00:14:53,430
and we can take a look
at the advanced section.

290
00:14:53,430 --> 00:14:55,830
And there's one main thing
that we wanna look at here.

291
00:14:55,830 --> 00:14:58,080
And that's speed and duplex

292
00:14:58,080 --> 00:15:00,330
when it comes to a wired connection.

293
00:15:00,330 --> 00:15:03,630
We're not interested in duplex
when it comes to wireless,

294
00:15:03,630 --> 00:15:06,120
but with wired connections, we are.

295
00:15:06,120 --> 00:15:07,789
Right now it's set to auto negotiate,

296
00:15:07,789 --> 00:15:11,493
but we can change the speed.

297
00:15:12,540 --> 00:15:15,600
The max we can run is one
gigabit, but we could change that

298
00:15:15,600 --> 00:15:18,189
to 100 megabits or 10 megabits.

299
00:15:18,189 --> 00:15:22,590
And you wanna know the
difference between full duplex

300
00:15:22,590 --> 00:15:23,940
and half duplex.

301
00:15:23,940 --> 00:15:26,490
Full duplex, which is what you want

302
00:15:26,490 --> 00:15:30,513
means that you can send and
receive data at the same time.

303
00:15:31,590 --> 00:15:36,590
Half duplex means that you can
either send or receive data

304
00:15:36,746 --> 00:15:38,970
only one at a time.

305
00:15:38,970 --> 00:15:41,330
So generally you want
it set to full duplex.

306
00:15:41,330 --> 00:15:45,469
But if your router that
you're connecting to

307
00:15:45,469 --> 00:15:48,390
has it set that way, and you set

308
00:15:48,390 --> 00:15:51,120
the client to auto negotiation,

309
00:15:51,120 --> 00:15:53,193
then it should set to full duplex.

310
00:15:55,380 --> 00:16:00,030
But there are a ton of
different options here.

311
00:16:00,030 --> 00:16:02,040
Some of which can make
things more efficient

312
00:16:02,040 --> 00:16:05,403
for your network connections
like flow control.

313
00:16:06,240 --> 00:16:10,350
Normally you want receiving
and transmitting enabled,

314
00:16:10,350 --> 00:16:11,183
but there's others

315
00:16:11,183 --> 00:16:14,220
that can actually make
the connection faster

316
00:16:14,220 --> 00:16:16,470
if you're working with
certain types of data.

317
00:16:18,120 --> 00:16:19,460
Right?

318
00:16:19,460 --> 00:16:21,450
So lots of information here
in the advanced section

319
00:16:21,450 --> 00:16:23,850
when it comes to network interface cards.

320
00:16:23,850 --> 00:16:26,460
So you wanna be able to get here for this.

321
00:16:26,460 --> 00:16:29,250
Let's take a look at the dpro42 card.

322
00:16:29,250 --> 00:16:30,420
We'll go to properties.

323
00:16:30,420 --> 00:16:34,530
And I said, I really shouldn't
have that IP on there,

324
00:16:34,530 --> 00:16:36,150
that secondary IP.

325
00:16:36,150 --> 00:16:38,550
So I just went to IP four, properties,

326
00:16:38,550 --> 00:16:41,793
and we'll go to advanced
and take a look here.

327
00:16:43,290 --> 00:16:48,000
Here is that 192.168.0.254,
which I don't want.

328
00:16:48,000 --> 00:16:49,830
So I'm gonna remove that.

329
00:16:49,830 --> 00:16:51,180
Click okay.

330
00:16:51,180 --> 00:16:52,680
Okay.

331
00:16:52,680 --> 00:16:54,300
We'll say yes for multiple gateways

332
00:16:54,300 --> 00:16:57,300
cause that's cause we have
two network cards on here,

333
00:16:57,300 --> 00:17:01,860
and close and make sure it
doesn't disable and re-enable

334
00:17:01,860 --> 00:17:03,630
or anything like that.

335
00:17:03,630 --> 00:17:05,520
And we should be good.

336
00:17:05,520 --> 00:17:09,300
Okay, we can also right click
and go to the status of this

337
00:17:09,300 --> 00:17:12,960
to see the connection and
what speed we're actually at.

338
00:17:12,960 --> 00:17:16,230
So we're at one gigabit
per second, which is good.

339
00:17:16,230 --> 00:17:18,300
And you can see how many
bites of information

340
00:17:18,300 --> 00:17:22,113
we've received here, over a million,

341
00:17:23,010 --> 00:17:26,220
and check that for the main network also.

342
00:17:26,220 --> 00:17:29,310
Check the status, make sure it
is at one gigabit per second.

343
00:17:29,310 --> 00:17:31,620
I'd love to have a 10
gigabit per second network,

344
00:17:31,620 --> 00:17:33,090
but I don't have it right now.

345
00:17:33,090 --> 00:17:36,870
And you could see much more
data being sent and received

346
00:17:36,870 --> 00:17:38,910
on this main network connection.

347
00:17:38,910 --> 00:17:40,590
That's where I'm doing
all my internet work

348
00:17:40,590 --> 00:17:43,140
and doing everything else and
connecting to a couple servers

349
00:17:43,140 --> 00:17:46,680
I have here where I
store data in a NAS box.

350
00:17:46,680 --> 00:17:49,650
So you can see here gigs,

351
00:17:49,650 --> 00:17:53,040
gigabytes of data sent and received.

352
00:17:53,040 --> 00:17:55,940
Once again, as I mentioned,
you could go to the run prompt

353
00:17:57,330 --> 00:18:01,503
and go to the device manager
by typing devmgmt.msc,

354
00:18:02,640 --> 00:18:07,410
bring up the device manager
to see those network adapters.

355
00:18:07,410 --> 00:18:08,970
And you can see the category here.

356
00:18:08,970 --> 00:18:10,290
I'm gonna minimize that.

357
00:18:10,290 --> 00:18:13,230
See the category here
network adapters, open it up.

358
00:18:13,230 --> 00:18:17,190
And we see indeed the ethernet connection.

359
00:18:17,190 --> 00:18:19,833
That is built in to the motherboard,

360
00:18:20,670 --> 00:18:23,879
and then this gigabit CT,
a separate network adapter

361
00:18:23,879 --> 00:18:24,990
that I installed there,

362
00:18:24,990 --> 00:18:28,203
and then anything for
virtual network adapters.

363
00:18:29,100 --> 00:18:31,437
But these are our two
physical network adapters,

364
00:18:31,437 --> 00:18:33,810
and we can find out more
about them by right clicking,

365
00:18:33,810 --> 00:18:35,160
going to properties.

366
00:18:35,160 --> 00:18:38,160
And again, advanced if
we wanted to find out,

367
00:18:38,160 --> 00:18:40,863
say speed and duplex.

368
00:18:43,230 --> 00:18:47,436
Packet priority, receive buffers,

369
00:18:47,436 --> 00:18:52,436
flow control, jumbo packets,

370
00:18:52,530 --> 00:18:54,240
you could do larger size packets.

371
00:18:54,240 --> 00:18:58,050
And so this gets more into
some in-depth networking,

372
00:18:58,050 --> 00:19:02,460
really I don't see it being
necessary for the A plus,

373
00:19:02,460 --> 00:19:04,260
but just another place you want to go to

374
00:19:04,260 --> 00:19:07,170
to be able to configure
your network adapter.

375
00:19:07,170 --> 00:19:09,270
So definitely the device manager

376
00:19:09,270 --> 00:19:11,883
the network connections,
network and sharing center.

377
00:19:13,140 --> 00:19:15,363
And also of course the command prompt.

378
00:19:16,650 --> 00:19:18,033
All right.

379
00:19:18,033 --> 00:19:22,140
So a little bit about network
interface configuration,

380
00:19:22,140 --> 00:19:24,660
and another quick tip for you here.

381
00:19:24,660 --> 00:19:29,130
Consider using simple names
for your network adapters.

382
00:19:29,130 --> 00:19:33,570
If they're wired, Microsoft in Windows 10

383
00:19:33,570 --> 00:19:36,855
will call it ethernet and ethernet two,

384
00:19:36,855 --> 00:19:39,690
but use simple names for this.

385
00:19:39,690 --> 00:19:41,250
This way, they're easier to work with

386
00:19:41,250 --> 00:19:44,830
if you ever have to work with
them in say the command line

387
00:19:46,710 --> 00:19:49,230
which you may have to do sometimes.

388
00:19:49,230 --> 00:19:50,070
All right.

389
00:19:50,070 --> 00:19:52,410
So there's a little bit
about network interface card

390
00:19:52,410 --> 00:19:56,430
or NIC configuration on the
wireless and the wired side.

391
00:19:56,430 --> 00:19:58,180
And that's about it for this video.
