In this video I'm going to test Wi-Fi sex is it as good as they say it is.
Now please note this video is more for informational purposes.
If you are studying for your CCMA and you short on time then feel free to skip this video.
In this video I'm actually not using a Cisco device I'm using a net gear router.
It's a device that I've added to my home network and I'm testing the throughput between various iPhones
and a server as well as a P.C. with a Wi-Fi six enabled network card and a server.
I want to test whether Wi-Fi 6 is as good as they say it is someone to test various IP phones iPhone
7 iPhone 10 iPhone 10 x s Max iPhone eleven.
I want to see are Wi-Fi six claims as good as they say it is.
Do we get good throughput with a Wi-Fi 6 device.
I think it's important that you see a practical example of Wi-Fi sex and see the throughput that it
gives you.
But if you're short on time then feel free to skip this video and go to the next video.
Otherwise continue watching
so here's the question.
Is Wi-Fi sex as good as they say it is.
Is it worth investing in a Wi-Fi six router so to help answer that question.
I've got a new next year router here.
This is an x 8 router the supports Wi-Fi sex.
So let's see if this actually performs as well as vendors see it does.
Now having a router by itself doesn't really help you.
You need clients.
So I've got a range of iPhone share iPhone 7 iPhone X iPhone X s Max iPhone eleven.
The only phone that supports a Wi-Fi 6 is the iPhone eleven so let's see if this actually makes a difference
to or should do another test.
I've got a Wi-Fi 6 enabled card here which I'll install in a computer and we'll test if this actually
makes a difference as well so does Wi-Fi 6 live up to the hype.
Is it worth you buying a Wi-Fi 6 router
now there is one issue here.
And that is that my home internet connectivity isn't that great.
In other words I don't have a fibre to home internet connection it's actually running quite slow here.
It typically runs at about 63 megabits per second.
This is not a good way to test how fast the Wi-Fi is so unlike other people I'm not going to try and
use an application on the phone that connects to the internet to test internet speeds or Wi-Fi speeds.
That doesn't really help.
What I'm gonna use is I perf I'm gonna run I perf on the phones on the run I perf on a P.C..
In other words on this Mac here and I'm going to connect via the Wi-Fi to that IP device and I'm going
to test the actual throughput I'll also do that using this network card sold test the throughput with
one P.S. using this and another P.C. connected to the physical network before going any further let
me give you the spoiler because some of you are not going to watch the entire video.
Is it worth getting Wi-Fi six enabled devices.
We'll have a look at these speeds on my iPhone eleven.
I think it's well worth it.
What about these speeds on a P.C. with a network interface cord that supports Wi-Fi sex.
I noticed that the difference in speed between a wired connection and a wireless connection using sort
of a controlled environment isn't that great.
So the Wi-Fi connection was approaching the speeds of the physical Ethernet connection in my P.C. speed
differences on phones very a lot.
You need to have a modern device like an iPhone 9/11 or Samsung Galaxy 10 that supports Wi-Fi sex.
A lot of new devices and I will be supporting Wi-Fi sex.
You can only get the true benefits of Wi-Fi sex and all the enhancements with regards to speed and so
forth.
If you have a client that's capable of Wi-Fi six different phones here not all of them support Wi-Fi
sex.
So you'll notice a difference in the speeds that they obtain using the Wi-Fi network.
Is it worth buying a Wi-Fi six enabled device.
Well I think it is in my tests.
I found that the iPhone 11 outperformed the other phones.
I also found that a P.C. with a Wi-Fi six enabled network card reached amazing speeds very close to
physical Ethernet.
Now there's obviously a lot of variables how far away are you from the access point.
What are you sending your traffic through if you're trying to go through a solid brick wall.
You're not necessarily going to get the same throughput as I did in my experiments where the device
was very very close to the access point or in this case the Wi-Fi enabled router but is it worth it.
I think it is but you need client devices that support Wi-Fi sex to justify the cost of purchasing a
Wi-Fi six enabled rider.
OK.
So without further ado let's get started and I'm going to show you in detail now how I set up this net
gear.
How I set up the P.C. with that network card how I tested the speeds on the iPhone's using IPF.
Okay so the first thing I need to do is um box my new home right.
This is a net gear right once again
hopefully it's going to improve the performance from my previous Wi-Fi connections which we're using
these Apple devices at these airports.
Hopefully this will be a lot better than the apple airports and other devices.
This is a modern net gear router.
I've got a very old one here which I'll use for explaining some concepts later.
This writer only supports 2.5 gigahertz attitude on 11 it says supports G networks 108 megabits per
second according to this.
So that old route it doesn't have the performance of a modern router this writer supposedly supports
to gigabits per second.
Wide connectivity for faster internet.
Now that's a problem with Wi-Fi sex.
The physical network that I have here at home only supports 1 gigabits per second.
So the switch as an example of one gigabits per second.
Now that's just a small switch that I've put on my desk for demonstration purposes.
I do have other switches in the house but they support one gigabits per second.
That means I need to upgrade my network to fully support Wi-Fi sex.
It's an issue that's going to be affecting a lot of networks in the real world because Wi-Fi six devices
can connect at greater speeds than one gigabits per second according to this 4.0 point gigabits per
second.
So in other words in theory a device connecting to this will be able to transmit at higher speeds than
my physical network okay enough talking Let's get this device out of here.
Now it comes with a quick start guide.
We've got the rod itself nicely packaged got powers of Kwai.
I'm based in the UK so we've got a UK power supply.
Got Ethan at cable and if I was based in Europe I'd use that but I'm not so used the UK plug.
Okay so we told on rapid as follows.
Take the plastic off
now on the road I've got a default network key so I can use my phone to connect to that as an example
if I connect to the wireless network it's got LCD options on and off it's got USB ports two of them
it's got five Ethernet ports two of which can be used in aggregate.
So do either channeling or some kind of channeling.
I've got an internet connection on an orphan.
Obviously got a power port as well so power the sun.
And then I'll connect to the network.
I won't bore you with the basic settings big thing is the test does it perform as they say it should
at Wi-Fi six speeds.
OK.
So I've got it plugged in and powered up.
Initially when it starts up it makes quite a bit of noise but then quite down.
You don't typically have your Wi-Fi devices however so close to your end devices.
So this will go upstairs in the roof but it's a case where it is for the moment.
Now I want to connect to that.
So
and I'm going to select join net get 75 don't want to join it.
Yes I do.
Ok so my initial tests I found that it didn't work as well as I expected.
I had to make some changes.
One of the changes that I had to make is make sure that the devices are connecting via five gigahertz
and not 2.5 gigahertz.
So I've got my three phones connected.
Fire the wireless network.
I've got my MacBook connected to the physical router so rather than having it connect to the switch
off connected directly to the broader.
In this example I've got an A bunch of pieces running within VMware on my Mac I have config shows me
that this is the IP address and what I'll do is start I perf on the server using this port number.
The right is making a bit of noise but hopefully you don't hear it.
What I'll do is on the first phone connect to the country server pulled 5 2 0 1.
Let's see what kind of speed we get.
And that's what I'd expect.
500 an 18 megabits per second in a 10 second period 521 megabits per second.
That's good.
On this phone 543 megabits per second varying a little bit.
I've only got a gig connection to the server but 545 megabits per second is good on this 1 700 something
800.
That's kind of the speeds that I would expect for Wi-Fi sex much better performance than the other phones.
This is obviously not very scientific got the device right next to me.
Three IP phones but kind of shows you what happens.
This is kind of what I was getting in previous tests.
So when I do that again we stall getting 700 something so 726 megabits per second.
Minimum 649 Max 7 7 4 on this phone
581 megabits per second.
Not too bad so minimum for eighty nine maximum 585 on this phone varying.
But once again so iPhone eleven 726 definitely made a difference in performance having Wi-Fi sex on
this phone 555 on this one 511.
So as I went through the generations of iPhone the throughput got better.
The new iPhone supports attitude at eleven a X which is Wi-Fi six previous generation supported attitude
at eleven AC Wi-Fi five and the same is true for the iPhone 10 so definitely had an increase in performance.
I'll run the phone right next to the access point I typically don't want to run it so close still getting
good performance though maybe a bit less than what we had before 670 over here getting better performance
a little bit further away from the access point it was too close to the access points so getting a bit
of a better speed I'll hold it right here next to the camera still getting decent speed 700 something
so not too bad it varies when I move the phone around but there you go I've demonstrated that Wi-Fi
sex gives us better performance through that device I'm getting great performance here on my devices
compared to what I would have previously got using my older Wi-Fi devices.
So let's see if this network code is as good as they say it is and let's see if Wi-Fi 6 is close to
a physical network connection now to help me do that I'm gonna run I perf on this computer as well as
that computer and I'm going to test it using a physical ethernet cable so I physically cabled that computer
to my net gear router and what we'll do is we'll try it using a physical connection and then I'll try
it using a wireless connection.
Okay so first thing hopefully you can see this.
I've got a wired connection and a wireless connection.
So what I'll do is turn off the wireless connection IP address shows me that the IP address on this
device is 10 0 0 12.
So that's the current IP address on the P.C. for clear of that.
And what I'll do is start the IP server so I perf is now running on that P.C. and what I'll do is start
the client on this P.C. and as you can see it transmitting over 900 megabits per second so that's excellent.
We're not getting gig speeds.
This only supports 1 gigabits per second.
But there you go.
That is a physical connection.
So I'll do that again.
Physically we are getting over 900 megabits per second okay.
But now let's do the real test.
So what I'll do is turn on the wireless and I'll disconnect the ethernet cable on the Roorda so on the
server you can see we only have a connection to wireless.
Now the IP address of the P.C. now is 10 0 0 4
over here 10 0 0 4 so I'll start I perfect game.
And on this side let's send traffic to 10 0 0 4.
OK so we still getting over 900 megabits per second.
I'm really happy with that performance.
Physically we were getting nine hundred forty one nine hundred thirty nine.
Now I'm getting 916 nine hundred and fourteen.
So sending traffic again we're getting over 900 megabits per second through the wireless connection.
So 921 920 I would say I'm really happy with that performance notice once again ethernet cable is disconnected
so there's no ethernet cable on that P.C. I'm getting 920 918 megabits per second.
So really happy with that performance.
Now once again on the P.C. IP address shows me that this is the IP address the Ethernet connection is
disconnected.
I only have a wireless connection enabled.
So start that server again
run I perf getting over 900 megabits per second I'll connect to the router
and as you can see this IP address is connected via wireless.
I only have three devices connected.
I've gotten a boon to server which is this one IP address shows me that this virtual machine running
on my Mac has an IP address of 10 0 0 6.
This is my Mac and this is the boon to P.C. running over there behind me.
So again I'll clear the screen connect to that a boon to P.C. using wireless or Wi-Fi sex.
You can see that we're getting over 900 megabits per second.
Again I'm limited physically to a 1 gig connection to this PCAOB here.
So 1 gig okay.
So I'm really happy with that performance.
Really happy with this network card.
Getting close to one gigabits per second of throughput using this Wi-Fi 6 adapter I could probably make
it even better if I had two Wi-Fi devices.
I found however that a phone to that P.C. doesn't do as well I can do one more test.
So here is my iPhone I'll start I perf go to the server.
10 0 0 4 and start downloading
code to make sure I'm on the right Wi-Fi network
start you're not getting the kind of performance that I would have expected getting over 100 megabits
per second but not what I would want to get
try upload that's better still not great for 100 megabits per second.
Much nicer to see over 900 so start that again
400 megabits per second.
Not too bad but again when I am doing it from P.C. to P.S. I'm getting over 900 megabits per second
so that's a lot better.
OK so that was a demonstration of Wi-Fi 6.
I've demonstrated Wi-Fi 6 from iPhones to a boon to server connected to the physical network.
I've also shown UPC on Ethernet physical Ethernet to Wi-Fi sex also phone to Wi-Fi sex.
I'm very happy with the speeds that I'm getting now.
Obviously I've got the rudder right next to me.
Typically you wouldn't do that you wouldn't have your devices right next to the rider now net gear do
you have a another type of device that has a 5 gig Ethan at port so perhaps if anyone's interested I
might buy one of those and then get a 10 gig switch and see if I can run at even higher speeds see if
I can get a higher throughput on Wi-Fi sex.
