Configuring Network and Internet Connectivity

1. Wi-Fi Setup

Households. Today, they're going wireless with 811 AC WiFi. They chose wireless over wired because it's less expensive to install and supports all their computing devices, from desktop computers to laptops, tablets, smartphones, and home automation. They purchased a new Soho router that will connect to their cable modem so the landline devices can get onto the Internet. But first, Barbie and Ken need to set up the router, which starts with a wired connection from computer to router. This is easy to do with a portable computer. We're going to go a little geeky here, so roll with me. Most of these instructions will be in the booklet packaged with a Soho router.

So first, plug the laptop into the router via an Ethernet cable. Then open a browser on the computer and type in the IP address of the router. For the laptop-to-router connection to work, both devices need to be on the same local area network, which is defined by both the physical connection and the IP addresses of both machines. By default, the router will have an IP address set by the manufacturer, often 192-1681 one. Also, by default, the router will provide an IP address to the laptop, making it part of the same LAN. Once Barbie makes the connection, she can log into the router. The linksys, router access, username, and password are set to admin and admin by default. That's the first thing that needs to change when you get into the actual router configuration login.

The basic setup screen has all of these sorts of local area network settings. Most of these you'll leave alone unless your Internet service provider tells you to make specific changes. About the only thing you would change automatically here would be the time zone to match your location. The Barbie Dream House, luckily, is in Malibu, California, and the time zone is set to Pacific time. So Barbie's golden. Okay, let's get the password changed.

There is a password field on the Administration tab. Enter the new password twice, and then click Save Settings. Wait for it. All right. Click. Continue. Now, let's set up the wireless. LAN Click the wireless tab. This router is ready for WiFi-protected setup by default, which is awesome for quick setup but doesn't provide the most robust security over time. To set up the router manually, click the "Manual" radio button, which is kind of conveniently labeled. The network modes for both 5 are set to mixed by default. That ensures that pretty much every WiFi device can connect with proper credentials.

You can change these settings to exclude older and slower devices if you want a somewhat faster WiFi experience with new devices. For now, let's just leave them mixed. The network name, or SSID, is set to a kind of generic Linksys default that needs to change. Let's try beautiful. And let's do the other one, too. Mom, use this beautiful.At this point, the channel widths and channels are mostly set to automatic. Those are fine if you run into problems with your neighbours and overlap and overuse channels; then you can change that later. But for now, the default is fine. The SSID broadcast is set to "enabled" and is set to "broadcast" by default.

There is some debate about whether turning off SSID broadcast will improve security. That's simply not true. Select Save settings, wait for them, and click Continue. The final basic setup requires wireless security. Click the wireless security sub tab. Security is disabled by default, but that's because it makes it easier to set up the thing that needs to change. You have many options with this router.

You can set it to WPA2-personal, or you can set it to Enterprise mode. If you have a Radius server, you can do that. Yes, because we left-mixed access for all of those older devices. WPA2 in WPA-mixed mode provides the best security. Select that for both. Enter a password or passphrase, such as "fly high, little bunny." You get the idea. Make this something not only easy to crack but also memorable. Any device that connects to this wireless network is going to have to use these credentials. When you're done, click Save Settings, and you're good to go. Oops, let's type something else in here and save the settings. Yay. The basic Soho router setup is complete.’

2. Going High Speed

Wired means plugging the device into a wall jack; wireless means using WiFi, such as 811; and cellular means using the cellular telephone network. Seven criteria determine which connection is best for Barbie and her friends to use: mobility, ability, reliability, throughput connection delay, its latency, number of concurrent connections, and level of security.

Mobility describes how far you can travel and still access network resources. The probability that a system will be functional is referred to as availability; in other words, can you rely on a service when you need it? Reliability refers to the quality of the data received and the error-checking and correction capabilities of the technology. Throughput refers to the data transfer rate. How quickly does your email download, and how long do you have to wait for a web page to load? Latency refers to the connection delay between a request and the response to that request.

The number of concurrent connections in this context refers to the number of simultaneous users who can connect to the Internet. The term "level of security" here means how resistant a connection type is to internet-based attacks. Before I go any further, let me state that wired always beats wireless and cellular. Except in the first category, "mobility," their cellular is king. Wired always wins for availability, reliability, throughput latency, number of connections, and level of security. Let's look at a few scenarios to see how things play out. Barbie and some friends want to download some huge files, like 4K video files, all at the same time. Which connection wins? Wired networks don't worry about signal loss or cloud cover, so they're available. Wired networks trounce WiFi and cellular in the quality of data received, so they are the most reliable.

Data speeds favour wired connections once again, with LANs reaching ten gigabits per second. Wired connections offer the lowest latency. They don't wait for a signal to travel across the air, bounce off of things, and so forth. Wired networks scale up quickly. Need to connect more devices? Add another switch to the network. Finally, wired connections offer great security as long as you don't let a bad guy plug into the network. Wireless or WiFi connections generally come in second place; the exception is the number of concurrent connections. WiFi networks support a dozen users or so, while cellular towers handle hundreds of users with no problems when Barbie and her friends head over to the gaming convention in Anaheim and connect via cellular rather than WiFi.

3. Setting Up and Sharing Printers

or set of tasks, depending on which kind of printer and which manufacturer you're dealing with. Some of them require you to run an installation program.

And during that installation programme that instals drivers and other software, at some point you'll be prompted to plug in the printer to a USB port on your computer. Others require you to plug them in and then install the drivers. We're going to do it that way. Windows 10 has two different ways to install a printer. To add a printer, as it says, we'll look at the old way that also applies to Windows 8 and Windows 7 and Vista, etc. and that is through the control panel. So the quickest way to get to Control Panel is to type and click Devices and Printers, and it will eventually load up. This is going to take a few minutes on this machine, so we'll fast-forward to the future. Because this is connected to my network at the office, Windows is going out over the network and polling every device connected to see any printers or devices that I have available to me here. If Windows recognises the printer, it would show up here, where it says Printers, and it's not there. So I need to install drivers to set up this printer in Windows.

There are two methods for doing the drivers. You can do it on a disc that you get right out of the box from the printer manufacturer, or you can go to the printer manufacturer's website and download the latest drivers. I advised that, and that's exactly what I did. Go to Downloads and double-click the actual file. There we go. And yes, I want to allow this app to make changes to my device. Yes, I want to install the printer and wait for it for a moment, select the user agreement, and click Next to begin the installation. Right now it's connected via USB, so I'm going to install it that way. Eventually, I'll install it via wireless. Once I decide where I want to put it, it finds it. And there we go, installing and giving me an ad for genuine Samsung toner—real value, true performance—from Samsung. And that's really all there is to do to set up a printer on a modern operating system. Before we move on to sharing printers, let's check to make sure that our printer works by printing a test page.

So, still in Control Panel, in Devices and Printers, right-click on the printer and go to Printer Properties. And right here at the bottom, you'll see "Print test page." There is a lovely black-and-white test page. Awesome. Okay, so the next step is to share this printer so that other people connected to our network can use it. Select Sharing. This opens the Properties sheet with the Sharing tab set, and you select Share This Printer. You can give it a name. Right now, it's the Samsung M 2020 series. Nice. You could call it Billy or Sue if you wanted to, but there you go. and click OK. This printer is now shared on the network. You can see this by going back to Devices and Printers. And notice the little people icon there that's showing that it's shared. That's great. To set up a printer in a modern operating system, all you had to do was install drivers, ensure you had good connectivity, and access the printer's properties. In this case, in the control panel, you can right-click the printer itself, select Properties, and share it. It's as easy as that.

4. AMA - Ask Me Anything About Networks and Internet Connectivity Part 1

I wanted to take some time to hear from you and answer questions you might have on computer fundamentals or computer literacy. So that's why we put together these "Ask Me Anything" episodes. My friend Aaron is going to ask questions about stuff in this chapter from viewers like you. I also want to hear from you as well. Well, my email is at the end of the episode; ask me anything. We have some general networking questions here. All right, I'm late on me first. What is the difference between a switch and a router? That's a good question.

A switch enables you to create a network. Okay. Right. As an example, suppose we wanted to connect two computers using magic cam. If we wanted these two laptops to be able to communicate, we could connect this laptop to a switch and connect that laptop to the same switch. And then they would be on a network and be able to communicate.

So a switch looks like this: We would connect this Ethernet cable into the switch and into the laptop, and then run another Ethernet cable to the same switch and into the other laptop. and that's how the network is created. Do you really want to clutter up your house with all these cables? Not at all. Okay. All right. Get rid of them. Most people ditch their cables these days, and they connect instead to a wireless access point. So a WAP creates a network as well.

You would connect this laptop to the Web wirelessly. Connect the other laptop to the Web wirelessly. Nice. and create that same kind of network. I like it. Cool, huh? Yeah. So what if you wanted to connect that laptop to the Internet? I would like that. You would like that? Yes. Okay. To do that, you are, in essence, creating a connection between your network and another network. Right. The Internet. For that, you need a different box, and that's called a router. So a router connects one network with another network. I see. Sweet, huh? Sweet. So what do you have at your house? I just have one black box.

That's how you connect to the Internet? Yes, that's how I get my Internet and cable service, or what? Yeah, with a cable company. Okay, so you also have a cable modem, right? Okay, so you have a switch, a router, a cable modem, and a web. just one box. One box. Okay. What you have is, maybe technically, or whatever he calls it, a magic box.

All of these different things, all of these features that I talk about A switch to create a network, a router to connect networks together, and the cable modem to enable your computer to communicate with your Internet service provider Right. And get on the Internet. All of these functions are built into that one box. Wow. Yeah, it's awesome. awesome little box. What it means in practise is that when you send a message to somebody on the Internet, You could also go look for a website. The stuff that you're doing on your local machine gets translated for Internet use.

That's my technical term for it. It is translated into signals that other things on the internet can understand and then goes out into the world to do the same thing. When you get a message on your computer, it's translated all the way through all these different devices, and what you see is that you've got mail. Wow. Right? So, the magic box Thanks. Black box. Awesome. So, not too long ago, I ran into a little bit of an issue at my house connecting to the Internet. Okay. We had four adults who all had multiple devices, and we were on them very often, and suddenly, my Mac, of all the devices in the house, would not connect to the Internet.

What can we do to help avoid that? This is a pretty common phenomenon where you have multiple people with multiple devices. Everybody's got a smartphone. They have tablets in their purses, and they're out using them. The kids are wandering around with smartphones, too. And everything is connecting, not necessarily to the cellular network but to the local WiFi. Right. And what you're running into is an issue with too many people ready for the 25-cent order for the day. Too many concurrent users Right. That just means you have more people than your LAN or SOHO router can handle.

Okay. Unfortunately, there are only a couple of things you can do. One, you can kick everyone else out so your Mac can connect. Right. Good luck with that. Or you can buy a better device. That's the real answer, which is to upgrade. I see. All right. Next, Ivan from Honolulu, Hawaii, asks, "How can I get wireless Internet on my PC, and how do I set it up?" That's a good question. Mac OS machines are no exception; most of them now include built-in Wi-Fi.

So with Macs, you don't have to worry about it. You have the option of plugging in, connecting wiredly, or connecting wirelessly. Wireless is not always included with PCs, especially larger desktop models. And so you can do a couple of things if you're a geek, right? You can go buy an expansion card, install it, open up the case, install the card, and install the drive. Okay. So a better option would be something like this little wireless network interface device.

Okay? Because ancient Wagon wheels this wireless Internet Connection network connection device that plugs into USB, we call them "mix." And then you have a driver disc that goes along with it. It's on a cable, so you can move it around. Nice, right? So you can adjust in case you have a dead spot, right? And connect to your wireless network just like you would any other wireless device. Awesome. That's all I have for Chapter 10. Thank you, Scott. You're welcome. And thank you.

5. AMA - Ask Me Anything About Networks and Internet Connectivity Part 2

I wanted to take some time to hear from you and answer questions you might have on computer fundamentals or computer literacy. So that's why we put together these "Ask Me Anything" episodes. My friend Aaron is going to ask questions about stuff in this chapter from viewers like you. I also want to hear from you as well. Well, my email is at the end of the episode; ask me anything.

Rachel from Raleigh, North Carolina, wants to know, "What do I need to know to connect to the Internet?" Okay, so, Rachel, it depends on where you live in North Carolina. Yeah, yeah. It depends on what part of North Carolina you live in. If you're way out in the country and far away from cities or big towns, then you probably have only a couple of choices, one of which is not great for the Internet, and that's dial-up. Dial-up will get you kind of low speeds—44 kb/s download speed—which is enough to do email but not really enough to do anything else on the Web.

A better choice, but one that is far more expensive, is satellite. Right. I'm not sure how satellite will transport you; it depends on where you are. However, a couple of times for a connection is acceptable, but not good enough to download YouTube videos. Yeah, but still not good enough to do some of the crazy things we can do on the Internet these days. If you live closer to a city, then you'll get one, two, or maybe three different high-speed internet service provider options. Most of the cable television companies, for example, offer high-speed, cable-based connectivity to the Internet, which these days can run at 100 megabits per second.

Well, right, at $50 to $75 or $100 a month. So, yeah, not bad. Fiber is another option; Verizon has fibre in some cities. Google Fiber is in some cities, too. And that can get you speeds up to a gigabit wow.per second, which is pretty awesome. One of the major telecommunications companies, AT&T, offers something in the middle called U. Verse—that'll get you high-speed Internet as well. And many of the telephone companies offer a slower, older service called DSL that will get you up to about six megabits per second, three times faster. No, thank you. So those are your options.

And so what you need to do is look. Right. Ask your friends, and find out who your Internet service providers are. I see. It depends on geography. Geography. I didn't realize. Absolutely. Next is Juan from Philadelphia. My uncle says he has this thing called a repeater in his two-story house. What is that? Oh, that's crazy. Uncle Juan. What he has is pretty standard when you have a multi-story dwelling. Remember the Barbie Dream House? Oh, yeah. And we talked about the placement of the wireless access point. Right. That needs to be centrally located, and that way you get good coverage throughout the environment.

In multilevel homes, you might get good coverage for one or two floors, but not the basement. You've been to my house? Yes. Right. The room that I'm in, where my study is on the piano and all that stuff, used to be a back porch. Oh, wow. Right. So the wall that separates that room from the rest of the house is an exterior wall. So what happens? I've taken very good care to place my lavatory in a central place, like in the kitchen, and I get great coverage throughout the house. I'm wandering around with my tablet, watching a movie. I walk through the door into my study, and it goes dunk of all places.

So I can do one or two things. And this is exactly what Juan's uncle has done, too. He could have run wires, added switches, and made this whole huge network. Or what he did was add a repeater, which connects to the WiFi connection on one floor and then broadcasts the signal out again to the floor below. Very nice. Yeah. So a repeater just enables you to extend the wireless network. Awesome. Good to know. That's all I have for Chapter 10. Thank you, Scott. You're welcome.
