1 00:00:04,720 --> 00:00:04,990 Okay. 2 00:00:04,990 --> 00:00:07,270 So here's the Windows ten laptop. 3 00:00:07,330 --> 00:00:09,490 That's the laptop on my left. 4 00:00:09,670 --> 00:00:13,990 Let's open a CMD prompt or command prompt. 5 00:00:14,230 --> 00:00:21,850 Run it as administrator to check whether this supports ad hoc networks. 6 00:00:22,180 --> 00:00:25,090 The command to do that is net. 7 00:00:25,810 --> 00:00:26,080 S. 8 00:00:26,710 --> 00:00:27,340 W. 9 00:00:27,340 --> 00:00:29,440 Lan show drivers. 10 00:00:31,470 --> 00:00:39,330 And what you need to check for is this hosted network support. 11 00:00:39,750 --> 00:00:48,030 So this command will tell us whether this network card in this PC supports ad hoc networks. 12 00:00:48,270 --> 00:00:51,270 As you can see here, this network card doesn't. 13 00:00:51,450 --> 00:00:57,210 So I can't use that laptop to set up an ad hoc wireless network. 14 00:00:57,540 --> 00:01:00,570 So what about the HP laptop? 15 00:01:00,840 --> 00:01:04,650 So I'll run a CMD prompt as administrator. 16 00:01:07,160 --> 00:01:12,530 Command is to h w lan show drivers. 17 00:01:13,550 --> 00:01:15,080 And here we have some good news. 18 00:01:15,080 --> 00:01:18,710 Notice hosted network support is yes. 19 00:01:18,950 --> 00:01:25,790 The computer on my right is an HP laptop running windows eight, but it does support ad hoc mode or 20 00:01:25,790 --> 00:01:27,020 hosted networks. 21 00:01:27,410 --> 00:01:28,600 So that's good news. 22 00:01:28,610 --> 00:01:32,510 I'll use this laptop now to set up the wi fi network. 23 00:01:32,960 --> 00:01:38,900 So first thing I did once again is check whether it supports ad hoc networks. 24 00:01:39,110 --> 00:01:41,330 And once again, we can see that it does. 25 00:01:41,660 --> 00:01:43,550 So what I'll do is clear the screen. 26 00:01:44,030 --> 00:01:45,580 So he has a quick cheat sheet. 27 00:01:45,590 --> 00:01:47,690 I've already opened up a command prompt. 28 00:01:48,170 --> 00:01:51,470 I've checked whether the card supports the feature. 29 00:01:51,470 --> 00:01:52,310 Yes, it does. 30 00:01:52,310 --> 00:02:00,740 So what I'm going to do is set up a wireless network with this SSID test ad hoc and with a key of this. 31 00:02:00,770 --> 00:02:05,090 Obviously not a good example, but it's fine just for this demonstration. 32 00:02:05,210 --> 00:02:07,250 You should use a better key than that. 33 00:02:08,479 --> 00:02:10,460 So I'll paste that in. 34 00:02:11,780 --> 00:02:19,970 And as we can see here, the hosted network mode has been set to allow the side of the hosted network 35 00:02:19,970 --> 00:02:21,800 has been successfully changed. 36 00:02:21,920 --> 00:02:26,960 The user key passphrase of the hosted network has been successfully changed. 37 00:02:26,960 --> 00:02:28,550 So that's all good. 38 00:02:28,580 --> 00:02:34,370 But it's not going to work until I start the hosted network. 39 00:02:35,130 --> 00:02:36,900 And this is where a lot of people have problems. 40 00:02:36,900 --> 00:02:43,110 That's why you need to check and make sure that your card supports ad hoc mode first, because when 41 00:02:43,110 --> 00:02:46,170 you type this command, it won't work. 42 00:02:49,060 --> 00:02:52,590 If the network code doesn't support ad hoc networks. 43 00:02:52,600 --> 00:02:55,210 But notice here we can see that the network has started. 44 00:02:56,110 --> 00:02:58,270 I'm going to open up control panel. 45 00:02:58,300 --> 00:03:00,160 Go to network and Internet. 46 00:03:00,580 --> 00:03:02,530 Go to network and sharing center. 47 00:03:04,390 --> 00:03:06,640 And notice we've got to test ad hoc. 48 00:03:06,670 --> 00:03:10,840 Now, it may take it a while to start that depending on your laptop. 49 00:03:10,840 --> 00:03:17,650 This is an older laptop, so it's quite slow, but hopefully you should see test ad hoc or the name 50 00:03:17,650 --> 00:03:19,210 of the network that you've created. 51 00:03:20,170 --> 00:03:25,000 So now I can go to my Windows ten laptop. 52 00:03:26,020 --> 00:03:34,090 I'll click on wi fi and notice I can see test ad hoc and I'm going to click Connect to connect to that 53 00:03:34,090 --> 00:03:34,900 network. 54 00:03:36,290 --> 00:03:42,320 Now again, it might be a bit slow because old laptop on the right here, I was hoping that the laptop 55 00:03:42,320 --> 00:03:45,350 on the left supported this feature, but it doesn't. 56 00:03:45,680 --> 00:03:48,350 It's a much newer laptop but doesn't support it. 57 00:03:48,800 --> 00:03:51,550 Notice we connected now, but there's no internet. 58 00:03:51,560 --> 00:03:53,270 We are secured, however. 59 00:03:53,600 --> 00:03:58,370 Now, the reason I was able to connect to the network without being prompted for a password is that 60 00:03:58,370 --> 00:04:03,710 I've previously connected to this ad hoc network, so I've previously tested this to make sure that 61 00:04:03,710 --> 00:04:04,370 it works. 62 00:04:04,580 --> 00:04:10,250 And I entered the password when prompted and Windows has remembered that password so it didn't have 63 00:04:10,250 --> 00:04:11,510 to enter it again. 64 00:04:11,510 --> 00:04:17,269 You would be prompted for the password if you hadn't connected to the network previously, so you'd 65 00:04:17,269 --> 00:04:20,000 be authenticated before you could join that network. 66 00:04:20,000 --> 00:04:24,320 In this case, I didn't have to once again, because I had previously connected from the Windows ten 67 00:04:24,320 --> 00:04:26,690 laptop to the Windows eight laptop. 68 00:04:26,990 --> 00:04:35,330 So going to command prompt on the Windows ten computer top IP config and I'll push this to more. 69 00:04:35,660 --> 00:04:42,650 I've got a whole bunch of network interfaces on this computer, but notice here, wireless adapter, 70 00:04:42,650 --> 00:04:46,070 wi fi, mss, home dot net. 71 00:04:46,880 --> 00:04:48,500 This is my IP address. 72 00:04:50,260 --> 00:04:52,790 I'll open up control panel on this computer as well. 73 00:04:52,810 --> 00:04:56,110 Go to network and Internet Network and sharing center. 74 00:04:56,740 --> 00:05:00,070 Notice we are connected to the public network. 75 00:05:00,250 --> 00:05:02,500 I can go to change adapter settings. 76 00:05:03,010 --> 00:05:07,180 I can see that my wi fi adapter is connected to test ad hoc. 77 00:05:07,420 --> 00:05:10,180 I'll double click on that, go to details. 78 00:05:10,510 --> 00:05:15,040 And as you can see, here's my IP address on this network interface card. 79 00:05:15,070 --> 00:05:19,240 I can also see the domain name MSS, home net. 80 00:05:20,630 --> 00:05:20,870 Okay. 81 00:05:20,870 --> 00:05:23,250 So I've connected to the wi fi network. 82 00:05:23,300 --> 00:05:25,220 Here's my default gateway. 83 00:05:28,710 --> 00:05:36,180 So on my cmd prompt ping 1921681 73.1. 84 00:05:36,660 --> 00:05:39,630 Notice I can ping the HP laptop. 85 00:05:40,310 --> 00:05:46,370 And to prove that on the HP laptop, I'll change my adapter settings. 86 00:05:48,010 --> 00:05:49,480 Here's my local area. 87 00:05:49,480 --> 00:05:52,960 Connection test, ad hoc details. 88 00:05:53,170 --> 00:05:57,430 You can see this is the IP address of this network interface code. 89 00:05:58,520 --> 00:05:59,830 But let's do a proper test. 90 00:05:59,840 --> 00:06:01,400 Let's try and share. 91 00:06:02,410 --> 00:06:07,660 A file from this laptop to that laptop using just the WiFi network. 92 00:06:07,900 --> 00:06:12,970 So at the moment, the HP laptop doesn't have a picture on its desktop. 93 00:06:14,990 --> 00:06:17,390 The Windows ten computer does. 94 00:06:17,390 --> 00:06:24,800 So I'm going to copy this image from the Windows ten computer to the Windows eight computer using the 95 00:06:24,800 --> 00:06:26,300 ad hoc WiFi network. 96 00:06:27,560 --> 00:06:35,580 So what I'll do is use a command prompt and type net use. 97 00:06:35,600 --> 00:06:38,340 You could do this through file explorer. 98 00:06:38,360 --> 00:06:47,210 I'm just going to do it through the CLI because then I can show you that I'm connecting to this IP address 99 00:06:47,210 --> 00:06:48,050 directly. 100 00:06:49,070 --> 00:06:52,700 So I'm going to basically create a network share. 101 00:06:52,970 --> 00:06:59,240 I'm trying to connect from PC on the left to PC on on the right to set up a network share. 102 00:07:00,790 --> 00:07:01,910 I'm also for my username. 103 00:07:01,930 --> 00:07:03,430 That's a good sign. 104 00:07:03,790 --> 00:07:09,250 Put in my password and notice I've connected successfully to the HP laptop. 105 00:07:09,670 --> 00:07:16,000 Net use shows me that this drive P is connected to the HP laptop. 106 00:07:16,540 --> 00:07:19,810 If I open up file explorer, go to this PC. 107 00:07:20,590 --> 00:07:26,410 Windows is unfortunately doing its normal thing where it's not showing the drive, so let's try and 108 00:07:26,440 --> 00:07:29,440 kick it into life by opening up another connection. 109 00:07:29,860 --> 00:07:31,570 So let's use queue here. 110 00:07:32,920 --> 00:07:35,080 So that's also connected successfully. 111 00:07:35,440 --> 00:07:41,170 If I type P as an example, notice I've moved to that directory type draw. 112 00:07:41,350 --> 00:07:49,900 I'm actually on the HP laptop here just to prove the point, when I go to the HP computer, I see the 113 00:07:49,900 --> 00:07:52,210 same files on both computers. 114 00:07:52,600 --> 00:08:00,640 As an example, if I make a new folder here called Ad Hoc WI Fi. 115 00:08:03,720 --> 00:08:06,870 Top deals are on the Windows ten computer. 116 00:08:06,900 --> 00:08:08,640 I see that folder. 117 00:08:10,090 --> 00:08:12,640 I'm going to go back to my local computer. 118 00:08:12,820 --> 00:08:14,010 So this is different. 119 00:08:14,020 --> 00:08:18,160 This is my local computer and I've got a image file here. 120 00:08:18,340 --> 00:08:26,350 So I'm going to type copy img eight to P backslash, ad hoc wi fi. 121 00:08:28,790 --> 00:08:30,380 One file has been copied. 122 00:08:30,470 --> 00:08:41,900 So jumping to the Windows eight computer C drive, ad hoc wi fi notice this file has been copied from 123 00:08:41,900 --> 00:08:44,179 Windows ten to Windows eight. 124 00:08:44,570 --> 00:08:48,620 Now, you wouldn't typically have to do this through the command line, but I'm just showing you that 125 00:08:48,620 --> 00:08:52,640 it is possible to copy files from one computer to another. 126 00:08:53,370 --> 00:09:00,780 So I was able to copy this image from the Windows ten computer to the Windows eight computer using the 127 00:09:00,780 --> 00:09:01,920 wi fi network. 128 00:09:02,100 --> 00:09:07,170 Now, I know a lot of people are going to ask me this, so let me explain how I'm controlling these 129 00:09:07,170 --> 00:09:08,340 two computers. 130 00:09:09,560 --> 00:09:10,400 Via. 131 00:09:11,150 --> 00:09:12,200 My Mac. 132 00:09:12,620 --> 00:09:21,290 I've physically connected to the PCs on the switch, but the PCs are communicating across the WiFi network. 133 00:09:21,590 --> 00:09:30,020 One of the reasons I wanted to show you through the CLI, what I'm doing is notice net use shows me 134 00:09:30,020 --> 00:09:35,780 that I'm connecting to this IP address, which is a wireless connection. 135 00:09:35,780 --> 00:09:42,410 So I'm not copying the files from the Windows ten laptop to the Windows eight laptop using the physical 136 00:09:42,410 --> 00:09:45,910 infrastructure or this physical Ethernet connection. 137 00:09:45,920 --> 00:09:54,290 I'm copying the file using the wi fi network because notice once again PE is connected to the wi fi 138 00:09:54,560 --> 00:09:55,370 connection. 139 00:09:55,610 --> 00:10:04,040 So if I go into control panel once again network and internet network and sharing center change adapter 140 00:10:04,040 --> 00:10:08,930 settings, notice the wi fi network is using the subnet. 141 00:10:09,290 --> 00:10:13,700 So I'm talking from one laptop to the other using the wi fi network. 142 00:10:14,610 --> 00:10:20,640 I could prove that by pinging the IP address of the HP laptops wi fi interface. 143 00:10:20,880 --> 00:10:22,290 So there's the ping. 144 00:10:22,890 --> 00:10:25,950 And what I'll do is disconnect the Ethernet cable here. 145 00:10:26,340 --> 00:10:30,780 And what you'll notice is I'm still able to ping. 146 00:10:33,940 --> 00:10:35,770 So we'll make that a continuous thing. 147 00:10:36,860 --> 00:10:44,120 And notice the Windows ten computer can still ping the HP computer, but I've lost my connection to 148 00:10:44,120 --> 00:10:52,340 that Windows computer because I disconnected the physical Ethernet cable so my Mac doesn't have a connection 149 00:10:52,340 --> 00:10:52,910 to it. 150 00:10:53,000 --> 00:10:54,170 I'll plug it back in again. 151 00:10:54,170 --> 00:10:57,110 Spanning trees is going to take a few seconds to bring that port up. 152 00:10:57,590 --> 00:11:00,920 I should have enabled port first on that port, but I didn't in this example. 153 00:11:00,920 --> 00:11:02,540 So take a few seconds. 154 00:11:02,930 --> 00:11:07,130 The Windows ten computer can still ping the HP computer. 155 00:11:08,260 --> 00:11:13,090 But I don't have connectivity to the Windows ten computer from my Mac. 156 00:11:13,120 --> 00:11:19,600 It's trying to connect now because that port is still transitioning to the forwarding state, which 157 00:11:19,600 --> 00:11:20,480 it's just done. 158 00:11:20,500 --> 00:11:23,180 I notice now I can see it on my Mac. 159 00:11:23,230 --> 00:11:28,030 So in this video I showed you how to set up an ad hoc network between two Windows computers. 160 00:11:28,540 --> 00:11:36,790 I was able to connect from the one Windows computer to the other, using a wi fi network hosted on that 161 00:11:36,790 --> 00:11:39,120 Windows eight computer, the HP computer. 162 00:11:39,130 --> 00:11:42,700 And then I was able to copy a file from the one computer to the other.
