Video: Getting on the Internet

I understand that not everyone watching this course is using a Mac that they've upgraded to Mountain Lion. And of course if you're watching this movie via the internet, at least one computer you've come in contact with has access to the internet. During the installation process, the Mac OS X installer nudged you to join a wireless network if one was available. Or if you had a wired connection to the internet, it was configured automatically. But it's possible that you weren't able to configure your internet connection or have questions about how to go beyond what's offered to you during installation, and that's what we're going to take a look at now.

Getting on the Internet

I understand that not everyone watching this course is using a Mac that they've upgraded to Mountain Lion. And of course if you're watching this movie via the internet, at least one computer you've come in contact with has access to the internet. During the installation process, the Mac OS X installer nudged you to join a wireless network if one was available. Or if you had a wired connection to the internet, it was configured automatically. But it's possible that you weren't able to configure your internet connection or have questions about how to go beyond what's offered to you during installation, and that's what we're going to take a look at now.

So I'll go to system preferences and I'll click on network. You see that you have a few options. The Mac I'm using has two ethernet ports and they're both listed here. It also has airport aboard so that's why Wi-Fi is there. You can connect via FireWire and you can connect via Bluetooth for other things. If you have a router that distributes internet addresses, your Mac will be using the Using DHCP entry. And this is a method for acquiring the address necessary to connect to the internet. The IP address, subnet mask, and the router appear below as well as the DNS server and search domains.

If you have a static IP address assigned to you by your internet provider, instead you would choose Manually, and then you would configure it there. And Wi-Fi is pretty much the same idea. Here's Wi-Fi, in this case, you would choose the network that you have access to. In this case I'm using the GUEST network. It's also in this area that I can show the Wi-Fi status in the menu bar. Once you have that up in the menu bar, the fan will indicate how strong the signal is. So if it's all black, it's very strong. If you see just a couple of bars, it's not quite so strong.

Click on that and then you could see any available Wi-Fi networks around you. Those that have locks next to them indicate that they're password protected. And let's turn that off. While we're here, let's click on the Advanced button. And go to TCP/IP. The one reason we go here is that, let's suppose that your Mac has become confused and you're not able to get onto the network. Sometimes one way to clear that up is to renew the DHCP lease. And to do that, again you go to this TCP/IP pane, click on renew DHCP lease.

This goes back, clears your router and it assigns a new DHCP lease. Now it could be that it ends up being exactly the same address. But at least it's cleared things up with your router and maybe that'll make things work better. I don't need to do that at this point so I'll click on cancel. Now if you can't seem to get things setup correctly or you can't get on the internet when you could before, click on the Assist me button. And you have a couple of options here. One is Assistant. If you click on Assistant you'll run through the whole process of setting up your network.

However, I find that Diagnostics is more useful when it did work but now it doesn't seem to. So click on Diagnostics, it will ask you what kind of network you want to use. In this case we have a couple of options, Ethernet, Wi-Fi or other. More important is the network status lights on the left side. In this case, all green means everything is good. Now in some cases, you may see that the first light is good, ethernet good, ethernet's working, network settings are fine but it's when you get to ISP that suddenly this turns red, indicating your computer and your ISP are not talking to each other. Or maybe that's on and the next light is out, indicating, well the ISP is telling me everything is okay but it's not getting onto the network.

So if this first ISP light is red, that indicates that you have some communication problem and it may be a problem with your Mac. However, if the ISP light is green and the internet light is red, that's a hint that your internet provider is having a hard time getting connected to the internet. So what you can do at this point is click on continue, and if it's working correctly as ours is. You'll be told so. But if not, you'll walk through a series of steps. It will ask you certain questions, is it plugged in is the first one. Make sure to check this setting or that setting, it will check some other things.

And often times it will finally come to the point where it says, "You're doing just fine but it appears that your ISP is having the problem, why don't you give them a call?" and that's not a bad idea. And we'll click on Quit because everything is going great. Now if everything really is going well, you should test it. So one way to do that is launch Safari, go to your favorite website and if it loads, everything is indeed okay. Quit that and let's move over to Sharing. If you seem to be having some problems with certain network services it may be that you haven't enabled them in your Sharing system preference.

For example if you think that you should be able to share files between computers, it maybe because file sharing has not been turned on. Check that, make sure it's turned on. Or you want to share a printer between two Macs, it doesn't seem to be working, and that could be because you haven't enabled printer sharing. However, there are some sharing services that should work automatically. For example, if you have two computers, they both have iTunes on them, you'd like to share the library from one of those computers to the other one, that should happen automatically as long as you have some kind of network connection.

Because they work over something called Bonjour, which is a zero configuration setup. They automatically see each other without you having to fiddle with stuff. We'll talk about sharing in another movie, but right now, things look like they're set up pretty well, so I'll quit that. And that's pretty much it as far as the Mac goes. If you can't get on the internet after this, it's likely not the fault of your Mac but rather a router or your ISP. Regrettably, troubleshooting these issues is beyond the mission of this course. As for sharing, again, we'll delve deeper into that subject in another movie.
