In this video, learn about restarting the modem, restarting the network, troubleshooting Wi-Fi connections, and get tips for properly configuring a router and setting up a Wi-Fi network.
- [Instructor] Network hardware trouble festers in several locations. The good news is that most network hardware trouble is pretty reliable, also the fixes are pretty simple. For example, and most internet service providers relate to this troubleshooting technique, to solve an internet connection turn off your broadband modem, wait about 30 seconds, then turn it back on again. Of course, turning it off really means unplugging the thing. I do this often enough that I've wrapped colored tape around the broadband modem's power cord.
I just unplug that cord, and wait, and then plug it back in again. Most of the time that solves the problem. If unplugging the modem doesn't work then you must unplug the modem and the router. That's assuming that the network has both devices separate. When you power down both the modem and the router reconnect the modem first, wait for all its lights to come on, specifically the ready light, if it has one. After the modem is up, plug in the router. When the router's up and running the rest of the network should be active.
Hopefully the issue is resolved. In some dire circumstances you may need to power down the entire network. For example, if you're having issues with multiple devices hogging the same network address turn all the network gizmos off, computers, printers, even switches or hubs if you use them. Then turn everything else back on, starting with the modem, the router, any switches or hubs, and finally the network devices.
Wireless, or Wi-Fi network connections have their own host of problems. Above all, keep in mind that you most likely should be in the same room as the Wi-Fi router or base station. Being in the next room over is okay, but the signal strength drops, two or more rooms away from the base station and the signal gets weak and unreliable. Yes, I know that the scientists claim that a Wi-Fi signal can go up to 300 feet. The operative words are up to. I'm sure that on the moon the signal is great at 300 feet, you just don't work on the moon, not yet at least.
In Windows 10 troubleshoot Wi-Fi issues from the Settings app. Press the Windows and I key combination to bring up the Settings app window. Choose Network & Internet, and Wi-Fi is the first item on the list, so it should come right up. Now on a laptop you will see the Wi-Fi toggle right below the Wi-Fi heading. To troubleshoot some Wi-Fi network issues turn the network adapter off, and then turn it on again. That may fix the problem. Or if the Wi-Fi is off you can turn it on.
On a desktop, which is this system here, the Wi-Fi's always on. Finally, you may have to do some network configuration on the router, which is officially called a gateway. You access the gateway through its webpage, so you need to know the local IP address and type that address into your computer's web browser. On this network the gateway has an address of 192 168 11. You can visit the website there to check the router's configuration.
Most routers don't need further tuning and tweaking, but you do wanna check on a few things. First, this router was just fired up, so the first thing we need to do is assign an administrator name and a password. This is a security precaution. The bad guys know all the default passwords. Once you've set a password, write it down, put it on a piece of paper and stick that paper right under the router. That way you'll never lose it. Make sure that you write down that that's the router's password. If there's a username, write down the router's username, then write down the router's password.
You want to make sure that this is labeled and in a spot where you can always find it. Second, for a Wi-Fi network you need to give that network a unique name and ensure that it's password protected with WPA2 security, or that you're using a WPS system. Now every single router's probably gonna have a different configuration screen. They're not all gonna look like this. In fact, I had to hunt around in here to find where many of the settings are. Good news, you'll only need to do it once.
Bad news, who knows what there are. So first thing we're gonna do is set the Router Name. This will be the name of the Wi-Fi signal you connect to. And I'm gonna call it Dansnetwork, all one word. Next I'm going to set security, that's on the Wireless tab, Wireless Security in this particular router's configuration. WPA2 Personal is exactly the security level I want. The Shared Key is the password. I'm going to type in the password, it's not gonna show up, so I'm also going to write that down on a piece of paper, the same piece of paper that I used for the router's password, 'cause the two are different.
This one is to access the network. So I'm gonna write down Wi-Fi network password, and then the name of the password I just typed in. The third thing you wanna do is you wanna ensure that the network is using DHCP to allocate the local network addresses. This is a far better configuration than static addresses, which are a headache to manage. So we go back to the Setup tab in this app, and you ensure that DHCP is active. If you changed any other router settings you need to restart the router, or just leave the webpage when you're done.
Generally speaking there should be a Save button or a Save item. So here it says Apply Settings and Save, I'm gonna go ahead and click Save, and the changes are saved. Now I do need to go ahead and reconnect to this Wi-Fi network using the proper network name and password, that's gonna happen to you at home too. Good news is routers rarely need attention beyond this. Updates might be available for security reasons, check the manufacturers website for updates, as well as directions on how they're applied.
