The topic that comes up the most when people ask me about computers is wireless networking (also known as Wi-Fi – Wireless Fidelity, or WLAN – Wireless LAN). What does 802.11g mean? How do I configure my router? How can I leech off of my neighbor’s wireless network? Since I’m running a technology blog, I thought I’d impart my knowledge on the technically-unsavvy (or the WLAN beginner). These tutorials are not for the super advanced networking guru, mind you, so don’t take it as such! This will be a three-part article, broken down into the following parts:
- What you’ll need to setup a wireless network (the part you’re reading now).
- What the standards mean.
- How to configure your wireless network once it’s been setup.
We’ll be practical here. I’m not going to bore you by going into detail about the out-dated wireless standards. You don’t want to know about old technology that you can’t buy anymore. Saying that, I will give you a single paragraph rundown on the origin of the terms IEEE and 802.11, because you’ll see them throughout this three-part article.
What do the terms IEEE and 802.11 mean?
The incremental wireless standards are designated by a letter (e.g. b, g, n) after the numbers 802.11. It’s called 802.11 because that was the name of the group formed to create the standard. You’ll see the acronym IEEE as well, which means ‘Institute of Electrical and Electronics Engineers’ – the organization that ultimately oversaw the 802.11 group and the creation of the wireless standard. The average consumer doesn’t need to know anything more than that. Pretty straight-forward, no?
Shopping for your wireless network.
Now, lets talk about what you’ll find when you shop for a wireless router. We’ll start with what you’ll need to setup a wireless network in your home – the basics. First, you’ll need a wireless router. There are plenty of makes and models, but generally they do the same thing. I won’t get into which is best, but I’ll tell you what I use. My wireless router is made by D-Link, using the ‘n’ standard (more on standards later). The other major router manufacturers are NetGear, Linksys, Buffalo, Belkin and TRENDnet. Like I said though, they all do generally the same thing. Don’t worry too much about the brand.
The next piece of equipment you’ll need (or won’t need) depends entirely on the computers you’re going to be connecting to your new WLAN. If you’ll be connecting a laptop, chances are you won’t need any additional hardware for it, unless your laptop is more than 5 years old (in which case I’d suggest using it as a door-stop or anti-theft device, instead of a computer). Laptops come with built-in wireless NICs (network interface cards), so chances are you won’t need to buy anything additional.
If you have a PC, you can either connect it wirelessly, or if it’s in close proximity to the wireless router, you can use a network cable and plug it directly into the back of the device. If it’s not close to the router, you’ll need to purchase a wireless NIC. The brand doesn’t absolutely need to be the same as the router, though I’d recommend it for compatibility sake. What you do have to watch for, however, is that the wireless NIC and the wireless router share the same standard. Most likely this will be ‘n’ or ‘g’. Routers and wireless NICs are usually backwards-compatible. Meaning, they’ll work on both standards (and previous standards as well).
You will need at least one network cable. This will be used to connect your router to whatever broadband device you’re using (cable or DSL modem). You’ll need a second cable if you want to connect your PC directly to the router. That’s all as far as hardware goes. Just two – possibly three – pieces of hardware. It doesn’t cost much to setup a WLAN. As I described above, the next article will be focused on the current Wi-Fi standards and what they mean. We’ll get a little more technical there.
