1 1 00:00:00,550 --> 00:00:02,800 In this video, I want to show you how 2 2 00:00:02,800 --> 00:00:06,360 to set up a wireless router using the proper settings. 3 3 00:00:06,360 --> 00:00:07,910 That means, we're going to be doing things like 4 4 00:00:07,910 --> 00:00:11,170 MAC filtering, setting the broadcast to disabled, 5 5 00:00:11,170 --> 00:00:12,540 and putting in a WPA2. 6 6 00:00:13,740 --> 00:00:16,190 So, as we go through, I'm going to use this 7 7 00:00:16,190 --> 00:00:18,200 Wireless-N wireless router. 8 8 00:00:18,200 --> 00:00:20,380 This is a standard wireless router you might find 9 9 00:00:20,380 --> 00:00:23,077 at Best Buy or Office Depot or some place like that 10 10 00:00:23,077 --> 00:00:24,490 and it's probably what you have 11 11 00:00:24,490 --> 00:00:26,240 something like this at home. 12 12 00:00:26,240 --> 00:00:27,920 This is a standard model that's going to have 13 13 00:00:27,920 --> 00:00:30,067 a wireless access point, a router, 14 14 00:00:30,067 --> 00:00:31,790 and a switch built in. 15 15 00:00:31,790 --> 00:00:34,140 So, as you can see, I have four different ports 16 16 00:00:34,140 --> 00:00:36,370 plus the WAN connection which will connect 17 17 00:00:36,370 --> 00:00:39,070 to my cable modem or my fiber modem. 18 18 00:00:39,070 --> 00:00:40,500 Now, what I'm going to do is switch over 19 19 00:00:40,500 --> 00:00:41,940 into the display and you'll be able 20 20 00:00:41,940 --> 00:00:43,740 to see my computer as we go through 21 21 00:00:43,740 --> 00:00:45,143 and configure this device. 22 22 00:00:46,280 --> 00:00:48,610 So, I'm on my desktop computer and I've opened 23 23 00:00:48,610 --> 00:00:50,450 up my network preferences. 24 24 00:00:50,450 --> 00:00:52,380 This shows me that I'm currently connected 25 25 00:00:52,380 --> 00:00:55,910 over ethernet directly to that wireless access point 26 26 00:00:55,910 --> 00:00:57,800 because it has those four switch ports, 27 27 00:00:57,800 --> 00:01:00,030 I'm plugged into port number one. 28 28 00:01:00,030 --> 00:01:02,230 I received a DHCP IP address, 29 29 00:01:02,230 --> 00:01:06,950 as you can see here, 192.168.1.2 30 30 00:01:06,950 --> 00:01:11,640 and the router is 192.168.1.1, 31 31 00:01:11,640 --> 00:01:13,650 so for me to be able to configure this 32 32 00:01:13,650 --> 00:01:15,728 wireless access point, I'm going to go 33 33 00:01:15,728 --> 00:01:18,410 and type in that IP address, 34 34 00:01:18,410 --> 00:01:21,580 that router IP address, into a web browser 35 35 00:01:21,580 --> 00:01:24,090 because most of these home access devices 36 36 00:01:24,090 --> 00:01:27,530 are going to allow you to have a web-based configuration. 37 37 00:01:27,530 --> 00:01:31,910 So, here I go 192.168.1.1 and it brings up 38 38 00:01:31,910 --> 00:01:34,250 a Netgear Genie which is this model 39 39 00:01:34,250 --> 00:01:36,040 of router that I'm using. 40 40 00:01:36,040 --> 00:01:38,430 So, do I want to use the genie to help me? 41 41 00:01:38,430 --> 00:01:41,080 I'm going to say no, we're going to configure this ourself. 42 42 00:01:46,050 --> 00:01:48,760 Now, currently, I do not have my cable modem 43 43 00:01:48,760 --> 00:01:51,050 or fiber modem plugged in so there will be 44 44 00:01:51,050 --> 00:01:52,940 no connection to the Internet, 45 45 00:01:52,940 --> 00:01:54,910 but I do want to go through and configure 46 46 00:01:54,910 --> 00:01:56,340 the wireless settings. 47 47 00:01:56,340 --> 00:01:58,440 So, I'm going to start by clicking on Wireless 48 48 00:02:00,440 --> 00:02:02,420 and under here you can see the first thing 49 49 00:02:02,420 --> 00:02:06,800 that we want to turn off which is Enable SSID Broadcast. 50 50 00:02:06,800 --> 00:02:08,850 According to the Network+ exam 51 51 00:02:08,850 --> 00:02:11,050 and the Security+ exam, you should 52 52 00:02:11,050 --> 00:02:13,950 disable the SSID broadcast because this 53 53 00:02:13,950 --> 00:02:16,030 is essentially your wireless access point 54 54 00:02:16,030 --> 00:02:18,720 going out and saying, hey, hey I'm over here, 55 55 00:02:18,720 --> 00:02:21,630 connect to me, my name is blank. 56 56 00:02:21,630 --> 00:02:23,230 We don't want to do that, so instead we're 57 57 00:02:23,230 --> 00:02:24,880 going to turn that off which means 58 58 00:02:24,880 --> 00:02:26,450 that each device in your area, 59 59 00:02:26,450 --> 00:02:28,650 you're going to have to actually type in 60 60 00:02:28,650 --> 00:02:31,160 the name of the network for them to connect. 61 61 00:02:31,160 --> 00:02:33,460 Then, do we want to have Wireless Isolation? 62 62 00:02:33,460 --> 00:02:35,020 I'm going to say yes. 63 63 00:02:35,020 --> 00:02:37,670 Now, the reason why is I'm using a Wireless-N 64 64 00:02:37,670 --> 00:02:39,370 router in this case. 65 65 00:02:39,370 --> 00:02:41,970 Wireless-N and Wireless-AC do support 66 66 00:02:41,970 --> 00:02:44,270 Wireless Isolation, this allows it 67 67 00:02:44,270 --> 00:02:47,140 to act more like a switch and less like a hub 68 68 00:02:47,140 --> 00:02:48,840 and that's what we'd like. 69 69 00:02:48,840 --> 00:02:50,720 So, we're going to go ahead and give it a name, 70 70 00:02:50,720 --> 00:02:52,910 and what is this SSID going to be called? 71 71 00:02:52,910 --> 00:02:55,193 I'm going to go ahead and call it Diontestwap, 72 72 00:02:57,000 --> 00:02:58,820 that's fine, and then it has you select 73 73 00:02:58,820 --> 00:03:00,260 the region, I'm in North America 74 74 00:03:00,260 --> 00:03:01,640 cause I'm in the United States, 75 75 00:03:01,640 --> 00:03:03,590 and you can either auto select the channel 76 76 00:03:03,590 --> 00:03:06,740 or specifically select the channel you want based 77 77 00:03:06,740 --> 00:03:10,530 on one through 11 if your running Wireless-B or G. 78 78 00:03:10,530 --> 00:03:12,010 Now, I'm going to let it auto select 79 79 00:03:12,010 --> 00:03:14,760 for me based on what is in my area, 80 80 00:03:14,760 --> 00:03:17,040 but if that was a problem, I could always go back 81 81 00:03:17,040 --> 00:03:19,620 and select one of the three most common channels 82 82 00:03:19,620 --> 00:03:22,110 that give us that separation, channel one, 83 83 00:03:22,110 --> 00:03:23,923 channel six, or channel 11. 84 84 00:03:24,760 --> 00:03:26,530 Next, I'm going to look at mode, 85 85 00:03:26,530 --> 00:03:29,127 and mode tells me how fast it's going to operate, 86 86 00:03:29,127 --> 00:03:32,290 am I going to be operating under Wireless-B or G, 87 87 00:03:32,290 --> 00:03:34,610 which would be 54 or can I go up 88 88 00:03:34,610 --> 00:03:38,988 to 150, which would be a mixed mode between G and N 89 89 00:03:38,988 --> 00:03:43,950 or can I go up to 300 which would give me just a Wireless-N? 90 90 00:03:43,950 --> 00:03:46,430 In my case, I do want to have this mixed mode 91 91 00:03:46,430 --> 00:03:48,210 because maybe I have some older devices 92 92 00:03:48,210 --> 00:03:50,250 that are still using Wireless-G 93 93 00:03:50,250 --> 00:03:52,040 and so, we'll do that. 94 94 00:03:52,040 --> 00:03:54,490 Then, we're going to look at our security options. 95 95 00:03:54,490 --> 00:03:56,260 Are we going to have no security, 96 96 00:03:56,260 --> 00:03:58,680 meaning, no password is needed? 97 97 00:03:58,680 --> 00:04:00,700 Now, sometimes, you may want that. 98 98 00:04:00,700 --> 00:04:03,460 For example, at our offices, we have a 99 99 00:04:03,460 --> 00:04:06,350 wireless network called dionguest, 100 100 00:04:06,350 --> 00:04:08,720 it has no password, you can go ahead 101 101 00:04:08,720 --> 00:04:10,130 and connect to it, and it's going to give 102 102 00:04:10,130 --> 00:04:11,910 you direct connection out to the Internet. 103 103 00:04:11,910 --> 00:04:13,630 It's isolated and there's nothing 104 104 00:04:13,630 --> 00:04:17,090 touching our network, it just gives you direct access out. 105 105 00:04:17,090 --> 00:04:18,960 But if you're setting this up for your home, 106 106 00:04:18,960 --> 00:04:20,900 you want to have a password cause you don't 107 107 00:04:20,900 --> 00:04:22,130 want somebody connecting into it 108 108 00:04:22,130 --> 00:04:24,120 and then touching your other devices. 109 109 00:04:24,120 --> 00:04:27,230 So, on this particular wireless access point, it only 110 110 00:04:27,230 --> 00:04:32,230 supports two different types of encryption, WPA or WPA2. 111 111 00:04:32,400 --> 00:04:35,500 Notice, WEP isn't here, why is that? 112 112 00:04:35,500 --> 00:04:37,490 Well, because WEP is easy to crack 113 113 00:04:37,490 --> 00:04:39,570 and I'm going to show you that in a separate video. 114 114 00:04:39,570 --> 00:04:40,840 But for right now, we have to choose 115 115 00:04:40,840 --> 00:04:43,560 between WPA and WPA2. 116 116 00:04:43,560 --> 00:04:46,200 Do we want WPA with a pre-shared key 117 117 00:04:46,200 --> 00:04:49,020 and using TKIP or do we want WPA2 118 118 00:04:49,020 --> 00:04:50,863 with a pre-shared key using AES, 119 119 00:04:51,700 --> 00:04:54,490 or do we want to support both of those, 120 120 00:04:54,490 --> 00:04:56,720 or do we want to support an enterprise mode? 121 121 00:04:56,720 --> 00:04:58,980 Well, if we're a home user, we're probably 122 122 00:04:58,980 --> 00:05:01,670 going to go for the most secure and easiest to use 123 123 00:05:01,670 --> 00:05:06,260 which is WPA2 with a pre-shared key using AES. 124 124 00:05:06,260 --> 00:05:07,600 And here's where you're going to choose 125 125 00:05:07,600 --> 00:05:10,760 some long passphrase and you want it 126 126 00:05:10,760 --> 00:05:13,560 to be something long and complicated 127 127 00:05:13,560 --> 00:05:16,120 and maybe it's something like that, I don't know. 128 128 00:05:16,120 --> 00:05:18,800 Or, maybe you have it as a long sentence, 129 129 00:05:18,800 --> 00:05:20,280 whatever it is you want to have something 130 130 00:05:20,280 --> 00:05:22,540 between eight and 63 characters 131 131 00:05:22,540 --> 00:05:24,290 and you want it to be long and complex 132 132 00:05:24,290 --> 00:05:26,120 because that lengthens the time it takes 133 133 00:05:26,120 --> 00:05:27,900 for somebody to break into it. 134 134 00:05:27,900 --> 00:05:29,730 So, we're going to go ahead and hit apply 135 135 00:05:29,730 --> 00:05:31,513 and that'll save those settings. 136 136 00:05:32,810 --> 00:05:34,840 Now, there wasn't a whole lot of in-depth 137 137 00:05:34,840 --> 00:05:35,900 setting here, right? 138 138 00:05:35,900 --> 00:05:38,090 They only gave me very basic things 139 139 00:05:38,090 --> 00:05:39,260 because they're trying to keep it easy 140 140 00:05:39,260 --> 00:05:40,550 for the consumer. 141 141 00:05:40,550 --> 00:05:42,700 What I want to do is I want to go to the Advance tab though 142 142 00:05:42,700 --> 00:05:44,840 and see if there's any more in-depth settings 143 143 00:05:44,840 --> 00:05:46,860 that we might be able to use. 144 144 00:05:46,860 --> 00:05:48,150 So, now that I went to Advanced, 145 145 00:05:48,150 --> 00:05:51,340 I'm going to go to Setup and I'm going to go to Wireless 146 146 00:05:51,340 --> 00:05:53,820 and we're going to see what settings we have. 147 147 00:05:53,820 --> 00:05:55,770 Again, there's not much there. 148 148 00:05:55,770 --> 00:05:57,510 Now, if I go to Guest Network, 149 149 00:05:57,510 --> 00:05:59,560 this particular access point allows me 150 150 00:05:59,560 --> 00:06:01,520 to have two different networks. 151 151 00:06:01,520 --> 00:06:04,460 I can have one for my personal and one for guest 152 152 00:06:04,460 --> 00:06:06,270 and the guest can connect and go directly 153 153 00:06:06,270 --> 00:06:08,350 out to the Internet, just as in the example 154 154 00:06:08,350 --> 00:06:10,089 I gave you at our business offices. 155 155 00:06:10,089 --> 00:06:12,450 So, maybe you want to do that for your friends 156 156 00:06:12,450 --> 00:06:14,983 and you're going to call it friendguestnetwork 157 157 00:06:16,838 --> 00:06:18,507 and you're going to allow isolation 158 158 00:06:18,507 --> 00:06:20,569 and you're going to enable this guest network 159 159 00:06:20,569 --> 00:06:22,480 and you're going to allow it to be broadcast. 160 160 00:06:22,480 --> 00:06:24,410 We're not going to allow guests to access 161 161 00:06:24,410 --> 00:06:25,800 your local area network, though. 162 162 00:06:25,800 --> 00:06:27,580 We want them to go directly to the Internet 163 163 00:06:27,580 --> 00:06:29,870 and not touch anything inside your network. 164 164 00:06:29,870 --> 00:06:31,670 And we can go ahead and set that up. 165 165 00:06:34,130 --> 00:06:35,590 Another thing we might want to do 166 166 00:06:35,590 --> 00:06:38,360 is we might want to use MAC filtering. 167 167 00:06:38,360 --> 00:06:40,120 So, if I want to enable MAC filtering, 168 168 00:06:40,120 --> 00:06:41,900 I need to find it first, and I believe 169 169 00:06:41,900 --> 00:06:43,900 it's under Advanced Setup here. 170 170 00:06:43,900 --> 00:06:45,610 And then, we're going to go down here 171 171 00:06:45,610 --> 00:06:48,363 and find it under Wireless Settings. 172 172 00:06:50,090 --> 00:06:51,440 And then under Wireless Settings, 173 173 00:06:51,440 --> 00:06:53,810 they call it wireless card access list 174 174 00:06:53,810 --> 00:06:55,970 and if I set up this access list, 175 175 00:06:55,970 --> 00:06:58,530 I can actually turn it on and only 176 176 00:06:58,530 --> 00:07:01,110 allow certain MAC addresses to be able 177 177 00:07:01,110 --> 00:07:03,650 to connect to this wireless network. 178 178 00:07:03,650 --> 00:07:05,900 So, the good thing about this is it will keep out 179 179 00:07:05,900 --> 00:07:08,550 people who don't know you're using MAC filtering. 180 180 00:07:08,550 --> 00:07:11,750 The bad thing is, as a hacker or an attacker, 181 181 00:07:11,750 --> 00:07:13,420 it only takes me about 30 seconds 182 182 00:07:13,420 --> 00:07:15,850 to bypass MAC filtering and so really it's 183 183 00:07:15,850 --> 00:07:17,630 a lot of work for you to be able 184 184 00:07:17,630 --> 00:07:20,150 to keep somebody out for maybe 30 seconds. 185 185 00:07:20,150 --> 00:07:21,670 But if you wanted to use it, you could go 186 186 00:07:21,670 --> 00:07:22,880 through and do it and we might say 187 187 00:07:22,880 --> 00:07:25,660 something like jasonsiphone, 188 188 00:07:25,660 --> 00:07:27,630 and then his MAC address, whatever 189 189 00:07:27,630 --> 00:07:29,180 that MAC address happens to be. 190 190 00:07:30,670 --> 00:07:32,390 And now, if I add that, it's going 191 191 00:07:32,390 --> 00:07:34,870 to allow that wireless network card 192 192 00:07:34,870 --> 00:07:38,220 to be able to connect to my wireless network 193 193 00:07:38,220 --> 00:07:40,060 and it will prevent everybody else 194 194 00:07:40,060 --> 00:07:42,370 if I turn access control on. 195 195 00:07:42,370 --> 00:07:43,860 Now, that's not my real MAC address, 196 196 00:07:43,860 --> 00:07:45,020 so I'm not going to turn that on 197 197 00:07:45,020 --> 00:07:47,193 but that's just an example of what you can do. 198 198 00:07:50,170 --> 00:07:51,950 The other thing I want you to look at here 199 199 00:07:51,950 --> 00:07:55,145 is WPS and WPS is something that was put 200 200 00:07:55,145 --> 00:07:57,960 into routers to make it easy for people. 201 201 00:07:57,960 --> 00:07:59,200 It's that button on the front 202 202 00:07:59,200 --> 00:08:01,700 of your wireless router, or wireless access point 203 203 00:08:01,700 --> 00:08:03,320 that you push the button on your device 204 204 00:08:03,320 --> 00:08:05,310 and you push the button on the access point 205 205 00:08:05,310 --> 00:08:06,970 and they'll automatically pair, 206 206 00:08:06,970 --> 00:08:09,220 share this router PIN with each other 207 207 00:08:09,220 --> 00:08:12,300 and then connect each other securely to the network. 208 208 00:08:12,300 --> 00:08:14,750 In theory, this was a great thing 209 209 00:08:14,750 --> 00:08:17,170 but unfortunately, it was easily hacked 210 210 00:08:17,170 --> 00:08:18,200 and so, it's something you do want 211 211 00:08:18,200 --> 00:08:20,530 to turn off for your best security. 212 212 00:08:20,530 --> 00:08:22,070 You'll notice on my device here, 213 213 00:08:22,070 --> 00:08:24,400 it doesn't give me the option of turning it off 214 214 00:08:24,400 --> 00:08:25,720 and so, I'm going to have to dig deep 215 215 00:08:25,720 --> 00:08:27,740 into the settings to turn this off. 216 216 00:08:27,740 --> 00:08:30,283 Most likely, it's here under the WPS Wizard, 217 217 00:08:31,430 --> 00:08:33,170 or under the Advanced Settings 218 218 00:08:33,170 --> 00:08:35,030 and we would go through and turn off 219 219 00:08:35,030 --> 00:08:38,780 that WPS if you're allowed to by your device. 220 220 00:08:38,780 --> 00:08:40,630 The last thing I want to talk about here 221 221 00:08:40,630 --> 00:08:42,230 is your remote management. 222 222 00:08:42,230 --> 00:08:43,670 If you click on Remote Management, 223 223 00:08:43,670 --> 00:08:45,470 this is something where it allows you 224 224 00:08:45,470 --> 00:08:49,190 to connect to the device remotely over the Internet 225 225 00:08:49,190 --> 00:08:51,790 through this web-based graphical interface. 226 226 00:08:51,790 --> 00:08:56,650 Now, we're doing this locally on 192.168.1.1 227 227 00:08:56,650 --> 00:08:57,930 and that's okay because you'd have 228 228 00:08:57,930 --> 00:08:59,610 to be connected to my network first 229 229 00:08:59,610 --> 00:09:01,200 to be able to access this device 230 230 00:09:01,200 --> 00:09:02,570 and make these changes. 231 231 00:09:02,570 --> 00:09:05,040 But if I turned remote management on, 232 232 00:09:05,040 --> 00:09:07,560 I can actually give it an IP address 233 233 00:09:07,560 --> 00:09:09,500 and allow anyone on the Internet 234 234 00:09:09,500 --> 00:09:12,300 to be able to connect to this device and make changes. 235 235 00:09:12,300 --> 00:09:14,190 Now, why would you want to do that? 236 236 00:09:14,190 --> 00:09:16,370 Maybe you have set this up for your mother's house 237 237 00:09:16,370 --> 00:09:18,200 and she's not very technically savvy 238 238 00:09:18,200 --> 00:09:19,460 and every time she has a problem, 239 239 00:09:19,460 --> 00:09:21,650 she's going to call you and ask you to fix it. 240 240 00:09:21,650 --> 00:09:23,450 So, if that was the case, you might want to 241 241 00:09:23,450 --> 00:09:25,091 turn this on, but you're going to want to configure 242 242 00:09:25,091 --> 00:09:27,752 it to only allow certain computers 243 243 00:09:27,752 --> 00:09:30,440 with certain IPS to be able to connect to it. 244 244 00:09:30,440 --> 00:09:32,120 Again, the best practice here is 245 245 00:09:32,120 --> 00:09:34,030 to turn off remote management 246 246 00:09:34,030 --> 00:09:36,170 and you'll notice it was off by default 247 247 00:09:36,170 --> 00:09:38,270 and keep it off to keep your device 248 248 00:09:38,270 --> 00:09:39,950 the most secure it can be. 249 249 00:09:39,950 --> 00:09:43,280 So, in summary, what are some of the big steps we did? 250 250 00:09:43,280 --> 00:09:46,170 Well, we wanted to make sure we're using WPA2 251 251 00:09:46,170 --> 00:09:49,310 with a good, long, strong, pre-shared key. 252 252 00:09:49,310 --> 00:09:52,190 We want to disable the SSID broadcast 253 253 00:09:52,190 --> 00:09:54,790 to make it harder for somebody to find our wireless network. 254 254 00:09:54,790 --> 00:09:57,430 We want to enable Wireless Isolation 255 255 00:09:57,430 --> 00:09:59,310 to keep those channels and frequencies 256 256 00:09:59,310 --> 00:10:01,660 isolated from each other from people connecting 257 257 00:10:01,660 --> 00:10:04,830 and make it act more like a switch and less like a hub. 258 258 00:10:04,830 --> 00:10:06,640 We also want to enable MAC filtering 259 259 00:10:06,640 --> 00:10:08,860 according to the exam, although honestly, 260 260 00:10:08,860 --> 00:10:11,140 in reality, I usually don't do MAC filtering 261 261 00:10:11,140 --> 00:10:13,240 because it's just more of a pain for me 262 262 00:10:13,240 --> 00:10:16,120 and it really doesn't give me that much more security. 263 263 00:10:16,120 --> 00:10:18,600 And finally, we want to disable the WPS 264 264 00:10:18,600 --> 00:10:20,310 setting, if you're able to. 265 265 00:10:20,310 --> 00:10:23,090 Again, WPS was a great idea for convenience 266 266 00:10:23,090 --> 00:10:24,840 but it doesn't provide good security 267 267 00:10:24,840 --> 00:10:27,660 and so, I would disable that anytime you can. 268 268 00:10:27,660 --> 00:10:29,490 I hope you take these tips and you put them 269 269 00:10:29,490 --> 00:10:31,640 to work in your own home or office network 270 270 00:10:31,640 --> 00:10:33,933 and get yourself a little bit more secure.
