WEBVTT 00:00.080 --> 00:06.410 So let's say you have configured the Raspberry Pi OS to connect to a Wi-Fi network here, WiFi network 00:06.440 --> 00:06.980 one. 00:06.980 --> 00:13.370 But then you go somewhere else and you need to use a different Wi-Fi network, and you don't have access 00:13.370 --> 00:15.680 to the one already configured. 00:15.710 --> 00:22.070 This can be a problem, because then your Raspberry Pi is kind of lost and you can't get access to it. 00:22.100 --> 00:29.330 You would either need to find an external monitor or to flash the SD card again with a new Wi-Fi configuration, 00:29.330 --> 00:33.740 which is not ideal because you would lose all the files here. 00:33.740 --> 00:38.960 In this video, I will show you how you can solve this problem and note that if you just install the 00:38.960 --> 00:42.950 Raspberry Pi OS and you can have access to the desktop, you don't need to do this. 00:42.950 --> 00:47.720 You can just keep this video and directly go ahead and go to the next section of the course. 00:47.750 --> 00:48.110 Okay. 00:48.140 --> 00:53.900 This video is more of a help you would potentially need in the future, in case you have the problem 00:53.900 --> 00:55.880 that I just described before. 00:55.880 --> 00:59.060 So now let's see how to solve this problem. 00:59.090 --> 01:03.590 And the first thing you can do, and I'm coming back to what I said before is just find an external 01:03.590 --> 01:05.510 monitor, maybe plug a keyboard and a mouse. 01:05.510 --> 01:07.010 That would be the easiest. 01:07.010 --> 01:09.920 Then you just pick the new Wi-Fi network. 01:09.950 --> 01:15.650 You could also try to use an Ethernet cable between your Raspberry Pi and your computer. 01:15.650 --> 01:21.530 And another solution that I also like is simply because you have your phone with you all the time, 01:21.530 --> 01:24.740 so you just use your phone as a hotspot for the Raspberry Pi. 01:24.770 --> 01:28.730 So then if you go to a new place, you can still use your phone as a hotspot. 01:28.760 --> 01:33.920 You can still connect your Raspberry Pi to your phone and then change the settings from there. 01:33.920 --> 01:39.110 But if you can't do any of that, then there is another solution that I'm going to explain right now. 01:39.830 --> 01:42.290 So the idea is quite simple. 01:42.290 --> 01:46.280 We will configure a hotspot on the Raspberry Pi okay. 01:46.310 --> 01:51.950 So that when we get to a new place and there is no Wi-Fi network that the Pi can connect to because 01:51.950 --> 01:57.590 it doesn't have the password, then the Raspberry Pi is going to boot as a hotspot from this computer, 01:57.590 --> 02:03.040 we will be able to connect to the Raspberry Pi, get access to the desktop, and then choose the new 02:03.070 --> 02:04.780 Wi-Fi network to connect to. 02:04.810 --> 02:05.320 Okay. 02:05.320 --> 02:09.640 And for this to work, we actually need to do a bit of preparation, okay. 02:09.670 --> 02:14.140 Because we need to configure the hotspot while we still have access to it. 02:14.140 --> 02:19.240 So while we are still connected here, you can see I'm connected to your Wi-Fi network. 02:19.240 --> 02:21.250 So it's the same network I have configured. 02:21.250 --> 02:24.040 And I'm going to connect to the Raspberry Pi. 02:26.290 --> 02:28.690 Okay I can keep it like this. 02:28.690 --> 02:32.230 And you can see the Raspberry Pi is connected to your Wi-Fi network. 02:32.230 --> 02:34.060 So that's the same thing we had before. 02:34.060 --> 02:35.590 And now we are going to configure. 02:35.590 --> 02:39.100 So I'm going to click here and go to Advanced Options. 02:39.280 --> 02:42.790 And we're going to create a wireless hotspot. 02:42.790 --> 02:49.630 So let's name it for example my RPI hotspot. 02:49.750 --> 02:56.800 You can choose whatever name you want and let's choose here WPA two personal okay. 02:56.830 --> 03:01.240 And let's put a password I choose a very simple password here. 03:01.270 --> 03:05.680 Well raspberry doesn't really matter and you can create it. 03:06.100 --> 03:12.010 You will notice that as soon as you create it, you lose the connection here because it's automatically 03:12.040 --> 03:13.720 gonna create the hotspot. 03:13.720 --> 03:17.260 So let's close Tigervnc here. 03:17.260 --> 03:26.800 And then if we go under settings here on the Wi-Fi settings of our computer, we should find the my 03:27.160 --> 03:29.140 my Raspberry Pi hotspot here. 03:29.140 --> 03:30.820 So I'm going to connect to it. 03:30.820 --> 03:34.600 And I will need to put the, uh pin. 03:34.630 --> 03:37.000 Now I'm going to use a security key instead. 03:37.060 --> 03:39.280 That's the password that I have set. 03:41.050 --> 03:42.730 So that's the raspberry. 03:42.760 --> 03:43.990 Same name I have set here. 03:43.990 --> 03:45.700 You can choose a different name if you want. 03:46.150 --> 03:47.230 Uh, next. 03:47.440 --> 03:52.810 And we should be connected to the Raspberry Pi hotspot. 03:53.080 --> 03:53.290 Okay. 03:53.320 --> 03:54.340 So we are connected. 03:54.340 --> 03:55.840 We don't have access to the internet. 03:55.870 --> 03:56.020 Okay. 03:56.050 --> 03:59.680 Because the Raspberry Pi has no internet access. 03:59.680 --> 04:05.830 And then I'm going to go, uh, again, connect with Tigervnc, but this time the IP address is not 04:05.830 --> 04:08.980 going to be the same because now the hotspot is the Raspberry Pi. 04:09.010 --> 04:12.610 So I'm going to go back to my IP scanner. 04:13.030 --> 04:13.870 Click here. 04:14.380 --> 04:21.370 And now with the Wi-Fi here you can see the network is 10.42 .0. something. 04:21.370 --> 04:25.930 And well you can start the scanner here. 04:26.110 --> 04:32.500 But yeah, what you will find is that the Raspberry Pi as a hotspot will have the IP address ending 04:32.500 --> 04:33.640 with one. 04:33.670 --> 04:36.610 Okay, so I think it should always be like that. 04:37.030 --> 04:47.380 I'm just going to stop once you find it and go back to Tigervnc and just use 10.42 .0.1. 04:48.070 --> 04:49.570 Let's connect. 04:52.690 --> 04:54.370 And we are back to the Raspberry Pi. 04:54.400 --> 04:59.050 This time the Raspberry Pi is the hotspot and our computer is connecting to it. 04:59.080 --> 04:59.680 Okay. 04:59.680 --> 05:01.390 And we just need to do one more thing. 05:01.390 --> 05:03.610 We're going to click here again. 05:03.640 --> 05:08.410 Go to Advanced Options and Edit Connections. 05:08.440 --> 05:14.350 We are going to click here on my API hotspot and click on the configuration. 05:14.380 --> 05:16.480 Here on the settings okay. 05:16.480 --> 05:20.080 And if you go to general so we don't change anything here. 05:20.080 --> 05:26.350 But if you go to general you can see connect automatically with priority zero. 05:26.380 --> 05:28.900 We keep zero here and you have to check that box. 05:28.900 --> 05:34.060 Because if you don't check that box then when you reboot your Raspberry Pi it's not going to create 05:34.060 --> 05:34.900 the hotspot okay. 05:34.930 --> 05:40.300 So we need to make sure that the hotspot is going to be created when we boot the Raspberry Pi. 05:40.300 --> 05:42.970 So I can click on save. 05:43.870 --> 05:44.560 Okay. 05:44.560 --> 05:46.570 And now I can shut down the Raspberry Pi. 05:47.110 --> 05:50.290 So I'm going to shut it down like this. 05:50.290 --> 05:54.310 And I can be sure that if so no close. 05:54.340 --> 05:54.820 Okay. 05:54.850 --> 06:00.940 I can be sure that if I go to any place where the Raspberry Pi cannot connect to a Wi-Fi, then it's 06:00.940 --> 06:07.590 going to create its own hotspot, and from this computer I can connect to the Raspberry Pi hotspot. 06:08.220 --> 06:11.040 All right, so what we did before was the configuration. 06:11.040 --> 06:17.670 Now let's say that we have arrived to a new place, and the Raspberry Pi doesn't know any of the Wi-Fi 06:17.700 --> 06:20.610 networks, so it cannot connect to any Wi-Fi network. 06:20.640 --> 06:24.630 Or simply you have changed your Wi-Fi Ssid or password at home. 06:24.750 --> 06:30.780 Okay, so the Raspberry Pi cannot connect to any network from this computer I have connected to. 06:30.810 --> 06:34.710 So here I have named it another Wi-Fi network. 06:34.740 --> 06:38.460 Okay, so that's my new network that I want to connect the Raspberry Pi to. 06:38.520 --> 06:45.810 So what I will do here is I will boot my Raspberry Pi, and the Raspberry Pi is going to start its own 06:45.810 --> 06:46.890 hotspot. 06:46.950 --> 06:55.050 So I'm going to wait a few seconds, maybe a minute or two, and then I can go there and I should find 06:56.010 --> 06:59.220 somewhere the Raspberry Pi. 06:59.250 --> 07:03.690 Okay, RPI hotspot, let's connect to this one. 07:05.010 --> 07:06.720 So connecting. 07:08.160 --> 07:08.430 Okay. 07:08.460 --> 07:11.820 And we are connected to my Raspberry Pi hotspot. 07:12.000 --> 07:14.370 Note that well of course we don't have internet. 07:14.400 --> 07:17.190 We just have a connection to the Raspberry Pi. 07:17.580 --> 07:25.440 I'm going to open Tigervnc again, and, well, that should be the same IP address as before, but you 07:25.440 --> 07:28.050 can use angry IP scanner if needed. 07:28.080 --> 07:29.280 Let's connect. 07:29.310 --> 07:29.490 Okay. 07:29.520 --> 07:30.360 It works. 07:31.560 --> 07:35.040 So let's connect and we have access to the Raspberry Pi. 07:35.130 --> 07:37.440 You could just keep it like this if you don't need internet. 07:37.440 --> 07:43.020 But here we're going to try to connect the Raspberry Pi to this new Wi-Fi network. 07:43.020 --> 07:45.240 So we're going to click on the Wi-Fi here. 07:45.510 --> 07:50.100 And what it doesn't see any thing okay. 07:50.130 --> 07:52.230 Probably because it's configured as a hotspot. 07:52.230 --> 07:58.830 So you can just click on Advanced options and connect to hidden wireless network. 07:59.850 --> 08:06.270 So when I click here and we're going to set here The network name, so the network name was another 08:06.270 --> 08:08.160 Wi-Fi network. 08:08.190 --> 08:10.770 Make sure you don't make any mistake, any typo. 08:10.800 --> 08:12.660 Okay, so another Wi-Fi network. 08:12.690 --> 08:15.450 So that's the network we want to connect to. 08:15.660 --> 08:21.210 And we're going to choose this one and put the password. 08:23.460 --> 08:29.370 So the password here is going to be the password of the new Wi-Fi network that you should have. 08:29.400 --> 08:32.160 Since you can connect your computer to this new Wi-Fi network. 08:32.190 --> 08:32.730 Okay. 08:33.090 --> 08:34.230 Let's connect. 08:34.230 --> 08:41.100 And well, as soon as we connect, of course, we're going to lose the connection from Tigervnc because 08:41.100 --> 08:44.370 the Raspberry Pi is connecting to another Wi-Fi network. 08:44.370 --> 08:48.120 And we don't have anything else with the hotspot. 08:48.120 --> 08:50.070 So you can see the error. 08:50.070 --> 08:51.540 So let's click on no. 08:51.990 --> 08:57.570 Then our computer, we're going to lose the connection to the Raspberry Pi hotspot because it doesn't 08:57.600 --> 08:58.500 exist anymore. 08:58.500 --> 09:01.560 And you see we are back to another Wi-Fi network. 09:01.560 --> 09:07.290 So make sure that you are back on that one, and then the Raspberry Pi and your computer should be connected 09:07.290 --> 09:09.060 to this new Wi-Fi network. 09:09.180 --> 09:13.920 So we are going to run an IP scan again. 09:13.950 --> 09:14.370 Okay. 09:14.400 --> 09:19.560 So make sure you have the correct Wi-Fi here. 09:19.560 --> 09:20.910 We scan again. 09:21.780 --> 09:22.590 Okay. 09:22.620 --> 09:24.060 Scanning completed. 09:24.090 --> 09:25.680 Let's sort by ping. 09:25.710 --> 09:27.660 You can see we even find it here. 09:27.660 --> 09:32.400 So 192 168 zero and 222. 09:32.430 --> 09:35.340 You can see that it's the same IP address as I had before. 09:35.370 --> 09:39.720 The network mask is the same simply because I'm using the same phone. 09:39.750 --> 09:45.210 I used different names for the Wi-Fi, but it's the same phone, so it's going to create the same IP 09:45.210 --> 09:45.480 address. 09:45.480 --> 09:49.770 But if you go to a different place, the IP address is probably going to look different. 09:50.100 --> 09:51.720 So tigervnc. 09:52.290 --> 09:54.900 And now we can do this. 09:54.900 --> 09:58.050 So we put the IP address. 09:59.190 --> 10:00.420 We connect. 10:03.230 --> 10:05.990 And we are back to the Raspberry Pi. 10:06.020 --> 10:10.160 This time we are connected to another Wi-Fi network. 10:10.190 --> 10:11.600 And what you can do? 10:11.660 --> 10:18.560 Well, if you want to be sure you are connected to this Wi-Fi network and that the Raspberry Pi doesn't 10:18.560 --> 10:26.450 start as a hotspot, you could go back to advanced options, edit connections, and then the hotspot. 10:26.480 --> 10:33.770 You edit the connection again here in the settings, you go to general and you remove this automatically 10:33.770 --> 10:35.900 connect and you save okay. 10:36.410 --> 10:41.750 This way the Raspberry Pi is going to connect automatically to this network. 10:41.780 --> 10:44.030 You are sure it's not going to start as a hotspot. 10:44.030 --> 10:45.590 And then you can repeat this process again. 10:45.590 --> 10:51.380 So if you're going again to a place where you don't know any Wi-Fi network in advance, so it's not 10:51.380 --> 10:56.900 saved on the Raspberry Pi, you just make sure first to start the hotspot, okay? 10:56.930 --> 10:58.520 By default on boot. 10:58.550 --> 11:00.320 So that's the configuration you need to do. 11:00.320 --> 11:04.340 And after this you can go to any place and do this process again.
