- [Dave] Hey, everyone Dave here.
This video is about network interface card configuration.
And so I'm gonna show a couple things here,
kind of move around a little bit.
We're gonna show a connection of a laptop's wireless card
to a Soho router wireless access point
that we set up previously,
and then we'll show some of the settings.
And then we'll take a look at a wired network interface card
from our main system
and show some of those settings as well.
So what we have here is I'm working at
the Windows 10 Pro laptop.
And down here, we have the icon for wireless.
If we click on that, we'll see
that we have a connection right now
to something called Unknown Network Five.
And that's a different wireless network
that I have running here.
I also have that wired connection, that ethernet connection
with this patch cable going directly to this.
And I've got that multi IP,
that multiple IPs set up on that
that we did previously, but I wanna connect this guy
to this in a wireless fashion.
And so we have two options for that.
We've got the 2.4 gigahertz network we set up
and the five gigahertz.
And that's what I want
because this has an 802.11 ACM.2 card in there.
So let's click on that.
And we'll click on connect,
and we need to enter the security key.
Okay, and we'll do that and click next.
It verifies and connects.
And we should get an IP address on that
in just a little bit.
There we go.
Connected and secured.
Let's take a look at that.
We got a couple places where we can look here.
First of all, we can look here.
We'll refresh our network connection screen
which is in the control panel.
And it shows here we have that ethernet wired connection.
And here's that wifi connection
now connected to EM-5-BACN.
Yes, and if we go to our command prompt
Clear it out, and we'll run an IP config.
We'll take a look at what we have.
Here's that wired connection with the two IPs,
and here's the wifi adapter.
And it gave us the Soho router.
The wireless access point gave the laptop 10.252.25.150.
So it chose to do that.
Now, remember the network we're on is 10.252.
the last two octets could be whatever this guy chooses.
And so we can prove that,
that we're on the same network as that Soho router
by doing a ping and pinging that IP address,
which is right here, 10.252.0.101.
and press enter.
And we get the replies.
So we're in, and we can look more at the adapter.
If we go back to our network connections,
we can right click on that.
And, you know, we could go to the properties
and find out more about IP
and anything that we have installed for that.
But we could also right click on that.
We could go to the status and see what we have here.
We have internet access through the Soho router
and our speed right now is at 433 megabits per second.
That's an 802.11 AC connection.
We can see here, we have full bars,
but really it's the data transfer rate or speed
or throughput that we're most interested in.
And that's gonna settle at 433 megabits per second.
We can also disable this if we need to here.
We can connect and disconnect from wireless networks,
bridge connections.
If we go back to properties,
let's say we want to configure this a bit more.
We can go to the configure button,
and that'll bring up the properties window for that device.
You can also get to this from the device manager.
And so you can see here
the device that's running, it's an AC 3160 M.2 card
that we saw physically when we opened the laptop.
And if we go to advanced,
we'll see lots of options here that we can work with.
For example, the channel width
that we have set up here for 5.2.
We wanna have this set to auto.
That's what the wireless access point is set to,
but you can change the width
from say 20 megahertz to 40 megahertz.
We're gonna leave that as auto,
but a couple of things that you wanna look at here.
For example, transmit power.
We can adjust the power of the wireless antennas.
And we said, you know, we have the M.2 card,
and it goes out and around through here and up here,
those antennas, we can adjust the power of those
between a value of one for lowest and five for highest.
Could be that we don't need five, the highest
especially because the laptop's right next to the router.
Well, it won't be later,
but let's see what happens if we change it to one.
Click okay.
Okay, it took a moment to reconnect
cause we're changing the radio power.
It's gonna identify and try to reconnect to it,
but I'll bet you it'll still be full bars.
And let's take a look at the status,
and it is the same because of the proximity here.
In some cases you may want to limit
the wireless connectivity, the radio power
because you may have a concern about war drivers
or people trying to access a laptop.
But I'm gonna put that back to five, the highest.
You never know, you might leave it as three, medium
because these are pretty powerful radios
that are in laptops.
So you may wanna reduce that.
And that could be company policy.
You also have things like wake up on Magic Packets,
and that's part of wake on LAN
So if some computer needs to access data on this laptop,
it could be woken up over the LAN
via the bios or UFI.
You have different wireless modes that you can set up here.
Roaming aggressiveness,
how aggressive is this wireless connection gonna be
when it's looking for a wireless access point
which you may need to set to higher.
The throughput booster which can work to increase
the data throughput rate or the data transfer rate
of a wireless network adapter if it's compliance.
There's a lot of options here.
Okay, but basically what you would do once again
to get to that is you'd right click on the card,
go to properties,
then go to configure, and then you'd go to advanced,
and you could make those changes from there.
And I'm gonna reset the transmit power to highest
and reset that.
Now you can also go to the control panel directly,
and let's say you wanna go to the control panel.
You can go to the run prompt and type control.
You can also do it by, you know,
going through the start menu and so on.
And then from the control panel,
we'd wanna go to our network and sharing center
and then go to change adapter settings,
and you could get to it from there.
Or you can go a little bit more direct
and go to the device manager,
which you can also get to directly from the run prompt
by typing devmgmt.msc,
that's dev management, and then find the network adapter
in this case, the AC 3160, right click that
and go to properties.
And your advanced settings will be there.
So different ways to get to the same thing basically.
And of course, be looking in your command prompt
to see all the data about that connection.
And we only did an IP config.
You could do an IP config slash all
to find out more information, and here's that wifi.
You can see the IP address that was handed to us,
the subnet mask, and that this is leased to us.
This is a lease
because it's given to us by a DHCP server .101.
That's the router, that's the Soho router,
the wireless access point,
which is also the default gateway.
It is also the DNS server.
You only see this additional information
and things like the Mac address
if you do an IP config slash all,
and it tells us DHCP is indeed enabled.
Yes, and this is the DHCP server that gave us the address.
For our ethernet adapter,
DHCP is not enabled.
It says no.
We statically configured those addresses here, right?
And so to connect to wireless networks,
you go to your icon here
which if you only have wireless, it'll look like this.
If you only have a wired connection,
it'll look like a little computer or a port connection.
And you'd right click on that.
And you could go to network and internet settings
or you could just click on it
to bring up those networks that it can see.
This is also where you could set up a hotspot
and set it to airplane mode
to turn off our all wireless activity.
If we right click and go to open a network
and internet settings, you'll see your actual connectivity
from the computer to the wireless network
out to the internet, shows you what you have here.
This is Windows 10,
and you know in a control panel,
you can also go to network and sharing center
to see that same type of information.
So two different places to go.
This is the new look for making these configuration changes,
but if you ever have to get more in depth
with the configurations,
then you'll end up in the control panel.
For example, somewhere like change adapter settings.
Okay, so you wanna be able to get around a little bit
and be able to view
how you can connect to wireless networks,
how to view those wireless networks,
how to use IP config and IP config/all,
how to get to the advanced settings
for the configuration of the wireless adapter,
all that stuff.
And so now let's move over to my main system.
We'll take a look at a wired connection
and some of the advanced settings for that.
Okay, so I've headed over to my main system here,
and this is the AV editor computer.
It actually has two wired network adapters, no wireless
just two wired.
And so to look at those, we could do an IP config.
We'll press enter,
and we'll see a variety of information here.
Some of which I've shown before
when we were doing some other work earlier
in another video.
So here is the main network that I connect to.
That's my main network where I do all my work.
You can see the IP network number is 192.168.41.
And this particular computer is 202.
The default gateway is 192.168.41.1
That's another router that I'm connecting to there.
Separate router altogether.
Then I also connect from this computer
with another ethernet adapter to my dpro42.com domain
which is that BACN network I was talking about previously
and using that 10.252 IP network number,
and this particular computer gets 10.252.0.254.
And the default gateway for that is 10.252.0.101.
And that is that router, that wireless access point
that we were just showing.
This way I can connect to my test network as well
with a second network card.
And I have another IP here
192.168.0.254 on this guy,
which is what I use normally,
that actually could create a IP conflict
because that is the address I used on the laptop
on the wired side.
It won't because there's no central connecting device
running 192.168.0,
but still they're both configured with that
as a secondary IP.
And I forgot I had done that here.
So that's one thing I wanna change,
but definitely be able to do your IP config
and also know how to do an IP config/all
so that you can see more in depth information.
Like I say, you can see if DHCP is enabled or not,
the Mac address, the DNS server.
It is not enabled on either of these.
I'm running statically for both of these connections.
So you wanna be able to do that.
You also want to be able to go
to the network and sharing center.
We'll bring that up here,
and you could see my connections here.
I have network and network two, right?
One is called main network.
One is called dpro42.
Click on those to find out more information
or you can go to change adapter settings to see those.
And so for example, we could go to say my main network
and take a look at that, go to properties.
We'll see all the different items that are used
by this connection.
Most importantly, IP version four.
And if we look at those properties,
we'll see the IP address that I added here.
We can go to configure,
and we can take a look at the advanced section.
And there's one main thing that we wanna look at here.
And that's speed and duplex
when it comes to a wired connection.
We're not interested in duplex when it comes to wireless,
but with wired connections, we are.
Right now it's set to auto negotiate,
but we can change the speed.
The max we can run is one gigabit, but we could change that
to 100 megabits or 10 megabits.
And you wanna know the difference between full duplex
and half duplex.
Full duplex, which is what you want
means that you can send and receive data at the same time.
Half duplex means that you can either send or receive data
only one at a time.
So generally you want it set to full duplex.
But if your router that you're connecting to
has it set that way, and you set
the client to auto negotiation,
then it should set to full duplex.
But there are a ton of different options here.
Some of which can make things more efficient
for your network connections like flow control.
Normally you want receiving and transmitting enabled,
but there's others
that can actually make the connection faster
if you're working with certain types of data.
Right?
So lots of information here in the advanced section
when it comes to network interface cards.
So you wanna be able to get here for this.
Let's take a look at the dpro42 card.
We'll go to properties.
And I said, I really shouldn't have that IP on there,
that secondary IP.
So I just went to IP four, properties,
and we'll go to advanced and take a look here.
Here is that 192.168.0.254, which I don't want.
So I'm gonna remove that.
Click okay.
Okay.
We'll say yes for multiple gateways
cause that's cause we have two network cards on here,
and close and make sure it doesn't disable and re-enable
or anything like that.
And we should be good.
Okay, we can also right click and go to the status of this
to see the connection and what speed we're actually at.
So we're at one gigabit per second, which is good.
And you can see how many bites of information
we've received here, over a million,
and check that for the main network also.
Check the status, make sure it is at one gigabit per second.
I'd love to have a 10 gigabit per second network,
but I don't have it right now.
And you could see much more data being sent and received
on this main network connection.
That's where I'm doing all my internet work
and doing everything else and connecting to a couple servers
I have here where I store data in a NAS box.
So you can see here gigs,
gigabytes of data sent and received.
Once again, as I mentioned, you could go to the run prompt
and go to the device manager by typing devmgmt.msc,
bring up the device manager to see those network adapters.
And you can see the category here.
I'm gonna minimize that.
See the category here network adapters, open it up.
And we see indeed the ethernet connection.
That is built in to the motherboard,
and then this gigabit CT, a separate network adapter
that I installed there,
and then anything for virtual network adapters.
But these are our two physical network adapters,
and we can find out more about them by right clicking,
going to properties.
And again, advanced if we wanted to find out,
say speed and duplex.
Packet priority, receive buffers,
flow control, jumbo packets,
you could do larger size packets.
And so this gets more into some in-depth networking,
really I don't see it being necessary for the A plus,
but just another place you want to go to
to be able to configure your network adapter.
So definitely the device manager
the network connections, network and sharing center.
And also of course the command prompt.
All right.
So a little bit about network interface configuration,
and another quick tip for you here.
Consider using simple names for your network adapters.
If they're wired, Microsoft in Windows 10
will call it ethernet and ethernet two,
but use simple names for this.
This way, they're easier to work with
if you ever have to work with them in say the command line
which you may have to do sometimes.
All right.
So there's a little bit about network interface card
or NIC configuration on the wireless and the wired side.
And that's about it for this video.
