1 00:00:00,210 --> 00:00:05,200 In this video I'm going to test Wi-Fi sex is it as good as they say it is. 2 00:00:05,340 --> 00:00:09,670 Now please note this video is more for informational purposes. 3 00:00:09,780 --> 00:00:15,210 If you are studying for your CCMA and you short on time then feel free to skip this video. 4 00:00:15,210 --> 00:00:19,860 In this video I'm actually not using a Cisco device I'm using a net gear router. 5 00:00:20,100 --> 00:00:27,030 It's a device that I've added to my home network and I'm testing the throughput between various iPhones 6 00:00:27,090 --> 00:00:32,710 and a server as well as a P.C. with a Wi-Fi six enabled network card and a server. 7 00:00:32,820 --> 00:00:39,210 I want to test whether Wi-Fi 6 is as good as they say it is someone to test various IP phones iPhone 8 00:00:39,210 --> 00:00:44,710 7 iPhone 10 iPhone 10 x s Max iPhone eleven. 9 00:00:44,910 --> 00:00:49,590 I want to see are Wi-Fi six claims as good as they say it is. 10 00:00:49,590 --> 00:00:53,280 Do we get good throughput with a Wi-Fi 6 device. 11 00:00:53,280 --> 00:01:00,810 I think it's important that you see a practical example of Wi-Fi sex and see the throughput that it 12 00:01:00,810 --> 00:01:02,030 gives you. 13 00:01:02,280 --> 00:01:07,160 But if you're short on time then feel free to skip this video and go to the next video. 14 00:01:07,170 --> 00:01:08,490 Otherwise continue watching 15 00:01:14,040 --> 00:01:15,290 so here's the question. 16 00:01:15,420 --> 00:01:18,150 Is Wi-Fi sex as good as they say it is. 17 00:01:18,150 --> 00:01:24,180 Is it worth investing in a Wi-Fi six router so to help answer that question. 18 00:01:24,180 --> 00:01:28,420 I've got a new next year router here. 19 00:01:28,470 --> 00:01:32,460 This is an x 8 router the supports Wi-Fi sex. 20 00:01:32,520 --> 00:01:38,420 So let's see if this actually performs as well as vendors see it does. 21 00:01:39,570 --> 00:01:42,500 Now having a router by itself doesn't really help you. 22 00:01:42,510 --> 00:01:43,830 You need clients. 23 00:01:43,980 --> 00:01:53,420 So I've got a range of iPhone share iPhone 7 iPhone X iPhone X s Max iPhone eleven. 24 00:01:53,520 --> 00:02:00,600 The only phone that supports a Wi-Fi 6 is the iPhone eleven so let's see if this actually makes a difference 25 00:02:01,620 --> 00:02:03,240 to or should do another test. 26 00:02:03,240 --> 00:02:11,160 I've got a Wi-Fi 6 enabled card here which I'll install in a computer and we'll test if this actually 27 00:02:11,160 --> 00:02:16,520 makes a difference as well so does Wi-Fi 6 live up to the hype. 28 00:02:16,560 --> 00:02:19,890 Is it worth you buying a Wi-Fi 6 router 29 00:02:32,140 --> 00:02:33,870 now there is one issue here. 30 00:02:35,420 --> 00:02:39,800 And that is that my home internet connectivity isn't that great. 31 00:02:39,800 --> 00:02:46,820 In other words I don't have a fibre to home internet connection it's actually running quite slow here. 32 00:02:46,830 --> 00:02:50,460 It typically runs at about 63 megabits per second. 33 00:02:50,490 --> 00:02:58,950 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 34 00:02:58,950 --> 00:03:06,030 use an application on the phone that connects to the internet to test internet speeds or Wi-Fi speeds. 35 00:03:06,030 --> 00:03:07,260 That doesn't really help. 36 00:03:07,440 --> 00:03:14,700 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.. 37 00:03:14,700 --> 00:03:21,620 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 38 00:03:21,620 --> 00:03:30,140 to test the actual throughput I'll also do that using this network card sold test the throughput with 39 00:03:30,140 --> 00:03:36,560 one P.S. using this and another P.C. connected to the physical network before going any further let 40 00:03:36,560 --> 00:03:41,150 me give you the spoiler because some of you are not going to watch the entire video. 41 00:03:41,150 --> 00:03:45,390 Is it worth getting Wi-Fi six enabled devices. 42 00:03:45,410 --> 00:03:49,390 We'll have a look at these speeds on my iPhone eleven. 43 00:03:49,400 --> 00:03:51,050 I think it's well worth it. 44 00:03:51,050 --> 00:03:57,790 What about these speeds on a P.C. with a network interface cord that supports Wi-Fi sex. 45 00:03:57,800 --> 00:04:03,890 I noticed that the difference in speed between a wired connection and a wireless connection using sort 46 00:04:03,890 --> 00:04:06,630 of a controlled environment isn't that great. 47 00:04:06,680 --> 00:04:13,460 So the Wi-Fi connection was approaching the speeds of the physical Ethernet connection in my P.C. speed 48 00:04:13,460 --> 00:04:15,520 differences on phones very a lot. 49 00:04:15,530 --> 00:04:22,900 You need to have a modern device like an iPhone 9/11 or Samsung Galaxy 10 that supports Wi-Fi sex. 50 00:04:23,030 --> 00:04:26,190 A lot of new devices and I will be supporting Wi-Fi sex. 51 00:04:26,300 --> 00:04:32,390 You can only get the true benefits of Wi-Fi sex and all the enhancements with regards to speed and so 52 00:04:32,390 --> 00:04:33,010 forth. 53 00:04:33,050 --> 00:04:39,590 If you have a client that's capable of Wi-Fi six different phones here not all of them support Wi-Fi 54 00:04:39,590 --> 00:04:40,310 sex. 55 00:04:40,310 --> 00:04:46,300 So you'll notice a difference in the speeds that they obtain using the Wi-Fi network. 56 00:04:46,310 --> 00:04:49,640 Is it worth buying a Wi-Fi six enabled device. 57 00:04:49,640 --> 00:04:51,700 Well I think it is in my tests. 58 00:04:51,710 --> 00:04:55,940 I found that the iPhone 11 outperformed the other phones. 59 00:04:55,940 --> 00:05:03,770 I also found that a P.C. with a Wi-Fi six enabled network card reached amazing speeds very close to 60 00:05:03,770 --> 00:05:05,040 physical Ethernet. 61 00:05:05,060 --> 00:05:08,680 Now there's obviously a lot of variables how far away are you from the access point. 62 00:05:08,720 --> 00:05:14,430 What are you sending your traffic through if you're trying to go through a solid brick wall. 63 00:05:14,450 --> 00:05:19,640 You're not necessarily going to get the same throughput as I did in my experiments where the device 64 00:05:19,640 --> 00:05:25,870 was very very close to the access point or in this case the Wi-Fi enabled router but is it worth it. 65 00:05:25,880 --> 00:05:32,420 I think it is but you need client devices that support Wi-Fi sex to justify the cost of purchasing a 66 00:05:32,420 --> 00:05:34,490 Wi-Fi six enabled rider. 67 00:05:34,610 --> 00:05:34,840 OK. 68 00:05:34,850 --> 00:05:40,520 So without further ado let's get started and I'm going to show you in detail now how I set up this net 69 00:05:40,520 --> 00:05:41,330 gear. 70 00:05:41,660 --> 00:05:50,250 How I set up the P.C. with that network card how I tested the speeds on the iPhone's using IPF. 71 00:05:50,550 --> 00:05:55,460 Okay so the first thing I need to do is um box my new home right. 72 00:05:55,880 --> 00:05:57,650 This is a net gear right once again 73 00:06:00,430 --> 00:06:07,150 hopefully it's going to improve the performance from my previous Wi-Fi connections which we're using 74 00:06:07,150 --> 00:06:10,030 these Apple devices at these airports. 75 00:06:10,090 --> 00:06:16,960 Hopefully this will be a lot better than the apple airports and other devices. 76 00:06:16,960 --> 00:06:19,780 This is a modern net gear router. 77 00:06:19,780 --> 00:06:25,600 I've got a very old one here which I'll use for explaining some concepts later. 78 00:06:25,750 --> 00:06:34,000 This writer only supports 2.5 gigahertz attitude on 11 it says supports G networks 108 megabits per 79 00:06:34,000 --> 00:06:36,000 second according to this. 80 00:06:36,220 --> 00:06:41,440 So that old route it doesn't have the performance of a modern router this writer supposedly supports 81 00:06:41,440 --> 00:06:43,010 to gigabits per second. 82 00:06:43,150 --> 00:06:45,700 Wide connectivity for faster internet. 83 00:06:45,760 --> 00:06:49,110 Now that's a problem with Wi-Fi sex. 84 00:06:49,120 --> 00:06:54,070 The physical network that I have here at home only supports 1 gigabits per second. 85 00:06:54,070 --> 00:06:57,010 So the switch as an example of one gigabits per second. 86 00:06:57,010 --> 00:07:01,510 Now that's just a small switch that I've put on my desk for demonstration purposes. 87 00:07:01,540 --> 00:07:07,340 I do have other switches in the house but they support one gigabits per second. 88 00:07:07,360 --> 00:07:11,910 That means I need to upgrade my network to fully support Wi-Fi sex. 89 00:07:13,030 --> 00:07:20,170 It's an issue that's going to be affecting a lot of networks in the real world because Wi-Fi six devices 90 00:07:20,170 --> 00:07:26,400 can connect at greater speeds than one gigabits per second according to this 4.0 point gigabits per 91 00:07:26,400 --> 00:07:27,330 second. 92 00:07:27,330 --> 00:07:35,670 So in other words in theory a device connecting to this will be able to transmit at higher speeds than 93 00:07:35,670 --> 00:07:40,750 my physical network okay enough talking Let's get this device out of here. 94 00:07:40,830 --> 00:07:45,240 Now it comes with a quick start guide. 95 00:07:45,270 --> 00:07:50,450 We've got the rod itself nicely packaged got powers of Kwai. 96 00:07:51,060 --> 00:07:57,120 I'm based in the UK so we've got a UK power supply. 97 00:07:57,240 --> 00:08:06,760 Got Ethan at cable and if I was based in Europe I'd use that but I'm not so used the UK plug. 98 00:08:21,580 --> 00:08:25,880 Okay so we told on rapid as follows. 99 00:08:28,940 --> 00:08:30,120 Take the plastic off 100 00:08:34,500 --> 00:08:42,760 now on the road I've got a default network key so I can use my phone to connect to that as an example 101 00:08:46,390 --> 00:08:54,790 if I connect to the wireless network it's got LCD options on and off it's got USB ports two of them 102 00:08:55,420 --> 00:09:01,250 it's got five Ethernet ports two of which can be used in aggregate. 103 00:09:01,270 --> 00:09:04,450 So do either channeling or some kind of channeling. 104 00:09:04,450 --> 00:09:06,470 I've got an internet connection on an orphan. 105 00:09:06,610 --> 00:09:12,320 Obviously got a power port as well so power the sun. 106 00:09:12,340 --> 00:09:14,990 And then I'll connect to the network. 107 00:09:15,060 --> 00:09:22,030 I won't bore you with the basic settings big thing is the test does it perform as they say it should 108 00:09:22,410 --> 00:09:25,190 at Wi-Fi six speeds. 109 00:09:25,190 --> 00:09:25,420 OK. 110 00:09:25,440 --> 00:09:27,300 So I've got it plugged in and powered up. 111 00:09:27,370 --> 00:09:32,000 Initially when it starts up it makes quite a bit of noise but then quite down. 112 00:09:32,020 --> 00:09:36,660 You don't typically have your Wi-Fi devices however so close to your end devices. 113 00:09:36,790 --> 00:09:42,230 So this will go upstairs in the roof but it's a case where it is for the moment. 114 00:09:42,250 --> 00:09:43,660 Now I want to connect to that. 115 00:09:43,660 --> 00:09:44,110 So 116 00:09:49,960 --> 00:09:55,870 and I'm going to select join net get 75 don't want to join it. 117 00:09:55,870 --> 00:10:04,820 Yes I do. 118 00:10:05,200 --> 00:10:08,930 Ok so my initial tests I found that it didn't work as well as I expected. 119 00:10:09,050 --> 00:10:10,330 I had to make some changes. 120 00:10:10,330 --> 00:10:16,660 One of the changes that I had to make is make sure that the devices are connecting via five gigahertz 121 00:10:16,660 --> 00:10:18,660 and not 2.5 gigahertz. 122 00:10:18,700 --> 00:10:20,640 So I've got my three phones connected. 123 00:10:20,690 --> 00:10:23,110 Fire the wireless network. 124 00:10:23,110 --> 00:10:29,530 I've got my MacBook connected to the physical router so rather than having it connect to the switch 125 00:10:29,550 --> 00:10:31,770 off connected directly to the broader. 126 00:10:31,930 --> 00:10:39,990 In this example I've got an A bunch of pieces running within VMware on my Mac I have config shows me 127 00:10:39,990 --> 00:10:50,640 that this is the IP address and what I'll do is start I perf on the server using this port number. 128 00:10:51,090 --> 00:10:55,340 The right is making a bit of noise but hopefully you don't hear it. 129 00:10:55,340 --> 00:11:01,670 What I'll do is on the first phone connect to the country server pulled 5 2 0 1. 130 00:11:01,670 --> 00:11:03,560 Let's see what kind of speed we get. 131 00:11:03,590 --> 00:11:06,120 And that's what I'd expect. 132 00:11:06,120 --> 00:11:13,250 500 an 18 megabits per second in a 10 second period 521 megabits per second. 133 00:11:13,280 --> 00:11:14,900 That's good. 134 00:11:14,900 --> 00:11:22,630 On this phone 543 megabits per second varying a little bit. 135 00:11:22,840 --> 00:11:33,480 I've only got a gig connection to the server but 545 megabits per second is good on this 1 700 something 136 00:11:33,720 --> 00:11:34,930 800. 137 00:11:35,200 --> 00:11:42,900 That's kind of the speeds that I would expect for Wi-Fi sex much better performance than the other phones. 138 00:11:42,910 --> 00:11:46,980 This is obviously not very scientific got the device right next to me. 139 00:11:46,990 --> 00:11:50,580 Three IP phones but kind of shows you what happens. 140 00:11:50,590 --> 00:11:53,810 This is kind of what I was getting in previous tests. 141 00:11:53,950 --> 00:12:02,060 So when I do that again we stall getting 700 something so 726 megabits per second. 142 00:12:02,180 --> 00:12:06,440 Minimum 649 Max 7 7 4 on this phone 143 00:12:10,050 --> 00:12:11,990 581 megabits per second. 144 00:12:11,990 --> 00:12:21,510 Not too bad so minimum for eighty nine maximum 585 on this phone varying. 145 00:12:21,530 --> 00:12:30,990 But once again so iPhone eleven 726 definitely made a difference in performance having Wi-Fi sex on 146 00:12:30,990 --> 00:12:34,820 this phone 555 on this one 511. 147 00:12:35,160 --> 00:12:41,140 So as I went through the generations of iPhone the throughput got better. 148 00:12:41,220 --> 00:12:48,900 The new iPhone supports attitude at eleven a X which is Wi-Fi six previous generation supported attitude 149 00:12:48,900 --> 00:12:59,590 at eleven AC Wi-Fi five and the same is true for the iPhone 10 so definitely had an increase in performance. 150 00:12:59,670 --> 00:13:06,950 I'll run the phone right next to the access point I typically don't want to run it so close still getting 151 00:13:07,010 --> 00:13:17,160 good performance though maybe a bit less than what we had before 670 over here getting better performance 152 00:13:17,160 --> 00:13:22,770 a little bit further away from the access point it was too close to the access points so getting a bit 153 00:13:22,770 --> 00:13:32,940 of a better speed I'll hold it right here next to the camera still getting decent speed 700 something 154 00:13:33,390 --> 00:13:41,310 so not too bad it varies when I move the phone around but there you go I've demonstrated that Wi-Fi 155 00:13:41,310 --> 00:13:47,400 sex gives us better performance through that device I'm getting great performance here on my devices 156 00:13:47,430 --> 00:13:52,890 compared to what I would have previously got using my older Wi-Fi devices. 157 00:13:53,190 --> 00:14:00,720 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 158 00:14:00,720 --> 00:14:07,740 a physical network connection now to help me do that I'm gonna run I perf on this computer as well as 159 00:14:07,740 --> 00:14:15,390 that computer and I'm going to test it using a physical ethernet cable so I physically cabled that computer 160 00:14:15,690 --> 00:14:23,640 to my net gear router and what we'll do is we'll try it using a physical connection and then I'll try 161 00:14:23,640 --> 00:14:25,880 it using a wireless connection. 162 00:14:25,920 --> 00:14:28,230 Okay so first thing hopefully you can see this. 163 00:14:28,230 --> 00:14:32,770 I've got a wired connection and a wireless connection. 164 00:14:32,940 --> 00:14:42,200 So what I'll do is turn off the wireless connection IP address shows me that the IP address on this 165 00:14:42,200 --> 00:14:45,600 device is 10 0 0 12. 166 00:14:46,070 --> 00:14:50,660 So that's the current IP address on the P.C. for clear of that. 167 00:14:51,170 --> 00:14:59,100 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 168 00:14:59,160 --> 00:15:07,950 the client on this P.C. and as you can see it transmitting over 900 megabits per second so that's excellent. 169 00:15:07,950 --> 00:15:09,530 We're not getting gig speeds. 170 00:15:09,550 --> 00:15:12,440 This only supports 1 gigabits per second. 171 00:15:12,720 --> 00:15:13,790 But there you go. 172 00:15:13,800 --> 00:15:16,640 That is a physical connection. 173 00:15:16,890 --> 00:15:18,360 So I'll do that again. 174 00:15:18,420 --> 00:15:23,990 Physically we are getting over 900 megabits per second okay. 175 00:15:24,020 --> 00:15:28,160 But now let's do the real test. 176 00:15:28,180 --> 00:15:43,090 So what I'll do is turn on the wireless and I'll disconnect the ethernet cable on the Roorda so on the 177 00:15:43,120 --> 00:15:51,010 server you can see we only have a connection to wireless. 178 00:15:51,130 --> 00:15:57,340 Now the IP address of the P.C. now is 10 0 0 4 179 00:16:00,780 --> 00:16:05,570 over here 10 0 0 4 so I'll start I perfect game. 180 00:16:09,500 --> 00:16:15,620 And on this side let's send traffic to 10 0 0 4. 181 00:16:15,660 --> 00:16:19,280 OK so we still getting over 900 megabits per second. 182 00:16:19,340 --> 00:16:21,400 I'm really happy with that performance. 183 00:16:21,500 --> 00:16:25,750 Physically we were getting nine hundred forty one nine hundred thirty nine. 184 00:16:25,760 --> 00:16:30,610 Now I'm getting 916 nine hundred and fourteen. 185 00:16:30,710 --> 00:16:38,960 So sending traffic again we're getting over 900 megabits per second through the wireless connection. 186 00:16:38,960 --> 00:16:49,280 So 921 920 I would say I'm really happy with that performance notice once again ethernet cable is disconnected 187 00:16:49,820 --> 00:16:59,160 so there's no ethernet cable on that P.C. I'm getting 920 918 megabits per second. 188 00:16:59,330 --> 00:17:02,170 So really happy with that performance. 189 00:17:02,190 --> 00:17:12,630 Now once again on the P.C. IP address shows me that this is the IP address the Ethernet connection is 190 00:17:12,630 --> 00:17:14,010 disconnected. 191 00:17:14,130 --> 00:17:17,030 I only have a wireless connection enabled. 192 00:17:17,430 --> 00:17:20,090 So start that server again 193 00:17:23,400 --> 00:17:30,750 run I perf getting over 900 megabits per second I'll connect to the router 194 00:17:36,210 --> 00:17:41,530 and as you can see this IP address is connected via wireless. 195 00:17:41,740 --> 00:17:44,160 I only have three devices connected. 196 00:17:44,160 --> 00:17:51,030 I've gotten a boon to server which is this one IP address shows me that this virtual machine running 197 00:17:51,030 --> 00:17:55,070 on my Mac has an IP address of 10 0 0 6. 198 00:17:55,180 --> 00:18:02,320 This is my Mac and this is the boon to P.C. running over there behind me. 199 00:18:02,320 --> 00:18:11,360 So again I'll clear the screen connect to that a boon to P.C. using wireless or Wi-Fi sex. 200 00:18:11,470 --> 00:18:16,200 You can see that we're getting over 900 megabits per second. 201 00:18:16,240 --> 00:18:22,210 Again I'm limited physically to a 1 gig connection to this PCAOB here. 202 00:18:22,210 --> 00:18:24,850 So 1 gig okay. 203 00:18:24,860 --> 00:18:26,510 So I'm really happy with that performance. 204 00:18:26,510 --> 00:18:28,940 Really happy with this network card. 205 00:18:28,940 --> 00:18:35,600 Getting close to one gigabits per second of throughput using this Wi-Fi 6 adapter I could probably make 206 00:18:35,600 --> 00:18:38,750 it even better if I had two Wi-Fi devices. 207 00:18:38,750 --> 00:18:46,380 I found however that a phone to that P.C. doesn't do as well I can do one more test. 208 00:18:46,380 --> 00:18:55,010 So here is my iPhone I'll start I perf go to the server. 209 00:18:55,240 --> 00:18:59,240 10 0 0 4 and start downloading 210 00:19:04,950 --> 00:19:07,840 code to make sure I'm on the right Wi-Fi network 211 00:19:13,020 --> 00:19:21,060 start you're not getting the kind of performance that I would have expected getting over 100 megabits 212 00:19:21,060 --> 00:19:24,750 per second but not what I would want to get 213 00:19:28,630 --> 00:19:35,620 try upload that's better still not great for 100 megabits per second. 214 00:19:35,800 --> 00:19:40,100 Much nicer to see over 900 so start that again 215 00:19:44,230 --> 00:19:45,560 400 megabits per second. 216 00:19:45,580 --> 00:19:53,140 Not too bad but again when I am doing it from P.C. to P.S. I'm getting over 900 megabits per second 217 00:19:53,170 --> 00:19:54,220 so that's a lot better. 218 00:19:55,590 --> 00:19:58,970 OK so that was a demonstration of Wi-Fi 6. 219 00:19:59,150 --> 00:20:06,430 I've demonstrated Wi-Fi 6 from iPhones to a boon to server connected to the physical network. 220 00:20:06,630 --> 00:20:14,750 I've also shown UPC on Ethernet physical Ethernet to Wi-Fi sex also phone to Wi-Fi sex. 221 00:20:14,760 --> 00:20:17,340 I'm very happy with the speeds that I'm getting now. 222 00:20:17,340 --> 00:20:19,670 Obviously I've got the rudder right next to me. 223 00:20:19,710 --> 00:20:24,820 Typically you wouldn't do that you wouldn't have your devices right next to the rider now net gear do 224 00:20:24,820 --> 00:20:30,930 you have a another type of device that has a 5 gig Ethan at port so perhaps if anyone's interested I 225 00:20:30,930 --> 00:20:37,350 might buy one of those and then get a 10 gig switch and see if I can run at even higher speeds see if 226 00:20:37,350 --> 00:20:39,690 I can get a higher throughput on Wi-Fi sex.
