19 00:01:00,810 --> 00:01:03,420 Well, first of all, it works good in a pinch 20 00:01:03,420 --> 00:01:06,870 if you don't have a connection for your laptop or your PC. 21 00:01:06,870 --> 00:01:11,430 So let's say the WiFi fails on a PC or laptop, 22 00:01:11,430 --> 00:01:15,990 or there's some type of issue with the network connection, 23 00:01:15,990 --> 00:01:19,530 then you could connect via USB directly to this 24 00:01:19,530 --> 00:01:22,260 and use that as a backup 25 00:01:22,260 --> 00:01:24,570 or just as a means of connecting a laptop 26 00:01:24,570 --> 00:01:27,120 if you're on the road and there's no access to WiFi 27 00:01:28,050 --> 00:01:31,470 or to a wired networking connection. 28 00:01:31,470 --> 00:01:33,870 So to make this work, 29 00:01:33,870 --> 00:01:36,150 what we do is we go to our Settings, 30 00:01:36,150 --> 00:01:40,200 and then go to Network, and go to Tethering. 31 00:01:40,200 --> 00:01:45,200 And this is also where the Mobile HotSpot is located. 32 00:01:45,480 --> 00:01:47,680 And then you wanna connect your device 33 00:01:48,540 --> 00:01:52,260 to your PC or your laptop via USB. 34 00:01:52,260 --> 00:01:55,560 So I've connected the other end to my desktop computer 35 00:01:55,560 --> 00:01:58,053 and connect this end here now. 36 00:02:00,540 --> 00:02:02,190 And once we do that, 37 00:02:02,190 --> 00:02:05,430 we get the option to actually do USB tethering. 38 00:02:05,430 --> 00:02:08,640 Before it was grayed out, it was disabled altogether. 39 00:02:08,640 --> 00:02:09,990 It doesn't become enabled 40 00:02:09,990 --> 00:02:12,333 until you actually connect that cable. 41 00:02:13,410 --> 00:02:17,040 Now, let's take a look at the PC side for a second, 42 00:02:17,040 --> 00:02:18,813 and I'm on the computer. 43 00:02:21,660 --> 00:02:23,340 And we have two networking connections. 44 00:02:23,340 --> 00:02:26,730 Now, this is a desktop computer, my main workstation, 45 00:02:26,730 --> 00:02:30,000 and it has two wired connections. 46 00:02:30,000 --> 00:02:32,730 It does not have a WiFi connection. 47 00:02:32,730 --> 00:02:35,190 I don't have any space inside the system for that, 48 00:02:35,190 --> 00:02:36,750 but I have connections to two networks, 49 00:02:36,750 --> 00:02:39,930 main-network and dpro42. 50 00:02:39,930 --> 00:02:42,690 And we can go to the change adapter settings screen 51 00:02:42,690 --> 00:02:44,130 to see those. 52 00:02:44,130 --> 00:02:47,910 The screens are blue, so we know that they are active, 53 00:02:47,910 --> 00:02:51,420 but let's say we lost our internet connection. 54 00:02:51,420 --> 00:02:53,730 And for example, this kind of thing 55 00:02:53,730 --> 00:02:56,340 can work great as a backup for somebody like me 56 00:02:56,340 --> 00:02:57,570 when I'm running webinars 57 00:02:57,570 --> 00:03:00,330 and everything runs through the internet connection. 58 00:03:00,330 --> 00:03:02,880 Well, let's take a look in the command prompt. 59 00:03:02,880 --> 00:03:05,100 I'm gonna do an ipconfig 60 00:03:05,100 --> 00:03:08,280 and take a look at my networking connections. 61 00:03:08,280 --> 00:03:10,080 I like to show these things in the GUI 62 00:03:10,080 --> 00:03:11,370 and in the command line. 63 00:03:11,370 --> 00:03:13,350 So here's main-network, 64 00:03:13,350 --> 00:03:16,470 the main ethernet adapter, that's the wired connection. 65 00:03:16,470 --> 00:03:21,470 It connects on the 192.168.41 network. 66 00:03:22,860 --> 00:03:25,470 And then we have the dpro 42. 67 00:03:25,470 --> 00:03:28,500 That's on the 10.252 network. 68 00:03:28,500 --> 00:03:30,270 So two different network connections. 69 00:03:30,270 --> 00:03:31,740 And one of the reasons I have that 70 00:03:31,740 --> 00:03:34,050 is so I can connect to a test network 71 00:03:34,050 --> 00:03:35,910 and also for a secondary internet connection, 72 00:03:35,910 --> 00:03:39,123 but the idea here is that the internet connections fail. 73 00:03:40,200 --> 00:03:42,840 So let's go back to our network connections, 74 00:03:42,840 --> 00:03:46,260 and to simulate that I'm going to disable these. 75 00:03:46,260 --> 00:03:48,870 Right click and disable each of them 76 00:03:48,870 --> 00:03:51,720 so they're grayed out, okay? 77 00:03:51,720 --> 00:03:55,290 I have just lost connectivity to a whole ton of stuff. 78 00:03:55,290 --> 00:03:56,340 So these are grayed out. 79 00:03:56,340 --> 00:03:58,420 If we go back to the command prompt 80 00:03:59,580 --> 00:04:04,080 and do another ipconfig and take a look, 81 00:04:04,080 --> 00:04:05,610 we will have nothing. 82 00:04:05,610 --> 00:04:07,350 Now, we have a lot of virtual connections. 83 00:04:07,350 --> 00:04:10,230 We've got VirtualBox, VMware, that kind of thing, 84 00:04:10,230 --> 00:04:12,480 but without those wired network connections, 85 00:04:12,480 --> 00:04:14,553 we really can't do anything. 86 00:04:15,390 --> 00:04:17,070 And so, for example, let's say I want to go 87 00:04:17,070 --> 00:04:18,363 to another page, 88 00:04:23,490 --> 00:04:25,890 and let's say I wanted to go to D Pro Computer. 89 00:04:25,890 --> 00:04:27,960 It'll say no internet cannot connect. 90 00:04:27,960 --> 00:04:30,600 So we have proven this computer cannot connect. 91 00:04:30,600 --> 00:04:34,470 Now we wanna go and check out the backup option 92 00:04:34,470 --> 00:04:36,780 so that we can connect. 93 00:04:36,780 --> 00:04:41,013 And so we'll go back to our phone here, our smartphone. 94 00:04:42,060 --> 00:04:44,100 We've already connected the cable. 95 00:04:44,100 --> 00:04:47,580 So now we'll go ahead and tap on USB tethering. 96 00:04:47,580 --> 00:04:50,010 Just tap on it to turn it on. 97 00:04:50,010 --> 00:04:52,500 And in most cases, that's all you have to do. 98 00:04:52,500 --> 00:04:56,220 Now, it tells you WiFi is turned off automatically 99 00:04:56,220 --> 00:05:01,170 when you turn on mobile hotspots or USB tethering. 100 00:05:01,170 --> 00:05:03,210 So WiFi gets turned off automatically. 101 00:05:03,210 --> 00:05:08,210 So I'll just OK that and cancel out of the learning option. 102 00:05:08,370 --> 00:05:12,540 And now we see that it is blue, so it is enabled. 103 00:05:12,540 --> 00:05:13,950 And that's really all you have to do. 104 00:05:13,950 --> 00:05:16,080 Now, in some cases on older devices, 105 00:05:16,080 --> 00:05:18,450 you'd have to do a little bit more configuration. 106 00:05:18,450 --> 00:05:22,230 And on older operating systems on a PC or the laptop, 107 00:05:22,230 --> 00:05:24,300 you'd have to install a driver 108 00:05:24,300 --> 00:05:25,830 or something special like that, 109 00:05:25,830 --> 00:05:28,830 but in most cases now, you don't have to do that. 110 00:05:28,830 --> 00:05:32,340 Let's go back to the computer. 111 00:05:32,340 --> 00:05:34,470 And I didn't do anything on this desktop. 112 00:05:34,470 --> 00:05:35,910 I'm doing this in real time. 113 00:05:35,910 --> 00:05:38,040 And if we refresh, 114 00:05:38,040 --> 00:05:42,213 it'll go right to the page that you want. 115 00:05:44,460 --> 00:05:45,990 Internet access will start to work. 116 00:05:45,990 --> 00:05:49,500 Here's my A+ Study Page from the 900 series. 117 00:05:49,500 --> 00:05:50,610 And so a little bit slower 118 00:05:50,610 --> 00:05:54,518 than the regular internet connection, but it works. 119 00:05:54,518 --> 00:05:57,063 23,000 visits to this page. 120 00:05:59,010 --> 00:06:00,780 So that is functioning 121 00:06:00,780 --> 00:06:02,250 and it worked right off the bat. 122 00:06:02,250 --> 00:06:05,460 But again, sometimes you'd have to go and install 123 00:06:05,460 --> 00:06:07,260 some type of driver 124 00:06:07,260 --> 00:06:10,290 or something for an older operating system. 125 00:06:10,290 --> 00:06:13,113 Today's systems should see it automatically. 126 00:06:15,120 --> 00:06:17,490 And if we take a look at our network connection screen, 127 00:06:17,490 --> 00:06:20,430 well, our main wired connections, they're still disabled, 128 00:06:20,430 --> 00:06:23,223 but now we have this, Ethernet 2, 129 00:06:24,180 --> 00:06:26,160 which has the blue screens. 130 00:06:26,160 --> 00:06:28,510 And if we go to our command prompt 131 00:06:30,510 --> 00:06:32,590 and do another ipconfig 132 00:06:33,720 --> 00:06:35,700 and take a look 133 00:06:35,700 --> 00:06:40,080 we will see Ethernet 2, bring this to the top here. 134 00:06:40,080 --> 00:06:44,250 192.168.42 network. 135 00:06:44,250 --> 00:06:47,280 Well, previously we had the main network connection 136 00:06:47,280 --> 00:06:49,560 on 192.168.41 137 00:06:49,560 --> 00:06:51,810 And in fact, that's what the smartphone 138 00:06:51,810 --> 00:06:53,550 was connecting with as well 139 00:06:53,550 --> 00:06:54,840 on its WiFi. 140 00:06:54,840 --> 00:06:56,940 When it was connecting via WiFi. 141 00:06:56,940 --> 00:06:59,760 That was on the 192.168.41 network. 142 00:06:59,760 --> 00:07:01,320 So what did the smartphone do?
