Join Nick Brazzi for an in-depth discussion in this video Connecting to the Internet, part of Mac OS X Yosemite Essential Training.
- If you’re using a computer chances are you’ll need to connect to the internet. You need an internet connection to browse the web of course, but you also need it to access the app store to buy new applications, to transfer files, to synchronize your mail, lots of other things. If you’re watching this course you’re already connected to the internet, so I’m sure a lot of people will skip this movie, but if you’re operating or setting up a second computer and you’re not sure how to get it connected, well let’s take a look. Now keep in mind I’m going to show you some general options.
We can’t get too advanced here, because there’s lots of specific variables to your network, so you may need to contact a contractor or your IT professional if your questions are not answered with this movie. With that in mind let’s take a look at our networking options which we’ll find in system preferences. I’m going to go to my main system menu and go to System Preferences. From here I’m looking for the option for Network, I’ll go ahead and click on that, and I can see all of my network connections.
I can see I have Ethernet, actually I have two Ethernet connections. This is the wired cable connection that you might have to a router or a DSL modem, or if you’re in an office or a university whatever wired connection you might have. In this case my computer has two Ethernet ports. Most computers don’t have two, this one does, but I’m really only using one of them. You can see I’ve got options here for FireWire, and Bluetooth. Usually these aren’t used for networking, but there are some scenarios where you can network through FireWire and Bluetooth which is why they’re here, but generally you don’t do anything with them here.
Most computers have Wi-Fi built in which will allow you to connect to a wireless internet connection. Now I want to look at the colors next to these, the green, the yellow and the red. The green means that I’m currently connected on this connection, so I do have an internet connection right now through Ethernet 1, and if I open up Safari for example, I go out on the web I load a webpage, I know that I’m getting that through my Ethernet connection. I’m going to go ahead and quit that. My Wi-Fi has yellow next to it that means that it is enabled, it is available to me, but it’s not the connection that I’m currently using, and the reds just mean that those connections are turned off or disconnected.
If I look at my Ethernet that’s where I’m currently connected. Let’s take a look at what happens if I disconnect the cable that’s connecting me to my internet connection through Ethernet. Now I’ve disconnected that cable, and Ethernet 1 turns red, so I’m no longer connected to the internet. If I go to Safari I’m not able to load this webpage. If you ever think you should be able to connect to the web, but you don’t get any connection you might come here to these settings and double check, and figure out what’s going wrong.
I’m going to go ahead and quit Safari. Now I do have another way to connect to the internet with my Ethernet unplugged, and that’s through Wi-Fi. You can see that it’s turned on, it’s just not connected to a network. If I go here to Network Name and pull down this drop list I’ll see all of the wireless internet connections that are available. If you’re in an apartment complex you’ll probably see all of your neighbors wireless routers listed here, but if you’re at an office you might just see one because that’s the only router that’s there in your office.
I’m going to choose the network I want to connect to. I’m going to choose LYNDA-GUEST, and in most cases you’re going to need to type in a password for a wireless connection. I’ve typed in the password I’ll hit join. It’ll take a moment to connect, and now my Wi-Fi has turned green, and it jumps to the top of the list, and if I open Safari the webpage loads, because I now have an internet connection. I’m going to quit Safari. It’s important to know where to go to adjust your network connections, and to know which one is connected at any given time.
Now for most people you probably want to have your Wi-Fi connection up here in the task bar in your menu, and you may already have it listed there. I’ve intentionally turned it off, but if you want to put it there you can come here to these network settings, make sure Wi-Fi is connected, and hit this box Show Wi-Fi status in menu bar. Then you don’t have to have system preferences open, if you’re just using your Wi-Fi connection you can click here and you can see all of the available networks.
You can turn Wi-Fi off if you want to right here, so if I turn that off then I won’t have any internet connection, but of course I could always, let me go back to System Preferences, back to network, and of course with my Wi-Fi off if I wanted to just reconnect my Ethernet cable I’ll see that connection will come back. Once that’s plugged in my Ethernet connection turns green, and that’s now the connection I’m using. That’s pretty much all it takes to connect to a network, but it does require a network to already exist which means you have to have an internet service provider or some IT person who set up the network in your office.
From here on we’ll be depending on the internet pretty heavily in this course, so I definitely recommend you get your connection situation all worked out. Fortunately, if you’re hearing my voice now you’re probably already connected to the internet, so you’re probably all set.
