A Simple Guide to Wireless Networking

Most folks want that laptop for work, school, or college. Most laptops these days are Wi-Fi enabled. That means that they have the wireless hardware and software built into the computer. To the average consumer, wireless is a form of magic. You turn it on and it works, right? Not always. Understanding the basics to wireless will help avoid frustration and headaches.

First, before we get into the basics of wireless networking, I have a few opinions to express.

It seems that everybody wants to go wireless with their laptops and desktop PCs. Wireless for laptops makes sense, since they get moved around between work and home and points in between. You can always connect using the Wi-Fi network at work or steal bandwidth from someone else. There are hotspots all over. There are ethical questions involved with borrowing?your neighbors signal. Let your conscience be your guide.

Wireless for desktops is an open subject. Since most of us usually set our desktops up on our home or office workstations, they tend not to move around. The only benefit of having a wireless desktop is that you dont have the expense and trouble of running Ethernet cable around your house. If you are not a DYIer, an Ethernet cable installation is an extra outlay. If youre lucky, your present PC is only a few feet away from your Broadband Modem. I personally prefer to have all my stationary PCs hooked up with Cat 5 Ethernet cables. That way I dont load up the wireless bandwidth on the router. Well talk more on bandwidth later.

There are hardware requirements to wireless networking. These are the things you need to communicate.

At home you need:

  • (1) a Broadband internet connection (Cable or DSL modem),
  • (2) a router to broadcast the wireless signal,
  • (3) a wireless enabled computer.
You cannot set up a wireless network using a Dial-Up connection. Period. I recommend that you power off your Broadband Modem and any existing computer systems before you begin the installation of the wireless router. The computing equipment will start to negotiate with your router automatically on start up. This will get you on the network without confusion. The router and existing PCs should not need any further configuration. The default or current settings should work. Your PC should already be set to DHCP in your Network Connections TCP/IP properties window. If it werent you would not have been able to connect to your ISP. This is a default setting of your PC.

The Broadband internet connection gear should already be present. Thats the Cable or DSL Modem that your Internet Service Provider installed when you got their service. Its connected to the Cable or DSL filter connection coming from your wall. The Modem has two connectors as a rule. One for the Cable or DSL data into the Modem, and one RJ45 connector you probably have connected to the computer you have in service now.

Youll need to unplug the Ethernet cable between the computer and the Modem. Reconnect that cable to your wireless router. It goes into a RJ45 connector usually labeled WAN?for Wide Area Network. The only other connection you will need to make is to connect another Ethernet cable between from one of the wired ports on the back of the router to your PC. There are usually 4 of them. Any one will do to reconnect your existing PC so its on the network. The existing PC will get its internet connection through this port. Your routers default settings should allow you to start connecting to your Wi-Fi enabled computers.

If all the cables are correctly placed, you should now be able to get on the Internet from you existing computers and your wireless computers.

Some quick notes of interest:

  • (A) Your Wi-Fi router is transmitting and receiving in the 2.4MHZ range. So are your Wi-Fi enabled computers. This is the same frequency range of a number of cordless telephones. You may have interference on your cordless phones once the Wi-Fi network is installed. If this occurs youll need to get 5.8 MHZ phones or put up with the noise.
  • (B) One of the most common questions I get is ?strong>I bought a wireless laptop and I cant get on the internet. Why not??If your wireless router is installed properly, then your wireless laptop may need configuration. Go to your Network Places or Network Neighborhood for a wizard to help you set up your computer for wireless.
  • (C) Bandwidth is the volume of traffic you can sustain through your network. The more devices using the Wi-Fi network, the slower the network uploads/downloads will be.
Remember, your wireless network works a lot like your cordless phone system. You need a transmitter/receiver at each end. Think of the router as the base station and the wireless PC as the handset. You cant talk on your cordless phone if the base station is unplugged. So without a wireless router in service, you cant communicate with the Internet. Hotspots are just spillover signal from someones wireless router.

Cable Vs. DSL - Which is Better?

As broadband Internet becomes more mainstream, one of the most common questions we get is: which is better, cable or dsl?

The answer to that question is not so definite. Many factors come into play when deciding which high-speed connection to choose. Regardless of which you choose (DSL, Cable, or even Satellite) its going to be a ton better (and faster) than that ancient dialup modem youve been using. Not to mention, your Internet experience will be much more enjoyable.

DSL (Digital Subscriber Line)

Just like your existing dialup modem, DSL uses your existing copper wire phone line to deliver data at high speed. To qualify for DSL, you need the following:

- a phone line

- a DSL modem (which normally comes with the service)

- an Ethernet card or an available USB port ( most DSL modems allow both connections, but Ethernet is recommended).

- a phone company (ISP) that is offering DSL service (e.g., Verizon)

One important factor that will influence your DSL connection is the distance between your home or office and the phone companys central office. The farther away you are from the central office, the signal becomes weaker, thus a slower connection. With that said, DSL is not as available widespread compared to cable. Youll need to contact your local phone provider to check availability.

Speed wise, depending on the package you choose, DSL can range from 128 kbps to 3 Mbps. Generally, the faster your connection the more expensive your service will be. You can expect to pay around $25-$30 a month for a 768 kbps connection, which is roughly 13 times faster than a 56k dialup modem.

::Pros::
- Relatively cheaper than cable
- Dedicated line, so speeds are almost guaranteed
- You can talk on the phone at the same time while surfing the net

::Cons::
- Slower speeds compared to cable
- Speeds drop the farther away your home/office is from the central office
- Not available in all areas

Cable Internet

Cable Internet gets our recommendation. Cable, which you can probably already tell, uses the coaxial cable that your television uses. To qualify for cable internet, you need the following:

- a cable modem ( which normally comes with the service)

- an Ethernet card or an available USB port (most cable modems allow both connections, but Ethernet is recommended)

- a cable company offering cable Internet (e.g., Adelphia)

Unlike DSL, cable Internet does not depend on the distance between your home or office and the central office. However, unlike DSL, cable connections are typically shared among your neighbors. Although, most cable companies provide pipelines with huge bandwidth that this rarely becomes an issue.

Speed wise, cable Internet typically ranges from 3 Mbps to 10 Mbps, up to 3-4 times faster than DSL. However, expect to pay more for the service - $40-$50 per month.

::Pros::
- Faster speeds than DSL
- More widespread than DSL
- Distance does not affect speed

::Cons::
- More expensive than DSL
- Line is shared with other users

With all that said, you need to think about what type of user you are. If you are a heavy Internet user and downloader, you would highly benefit from a broadband connection. For the light users who use the Internet just to check emails, are probably better off with a dialup. However, if you are willing to splurge some cash on a broadband connection, then by all means, upgrade!

One Big Broadband Hot Spot

This isn't the Cosmo magazine kind of hotspot; it's the other kind you may be hearing about: the Broadband hotspot. They seem to be everywhere, you can sip a latte in Starbucks while browsing the net, or have a pint at the pub while you delete annoying emails from your mother But these little hotspots, once just covering a pub or a caf here or there, are growing bigger. Just last year the River Thames in London was made into a gigantic broadband hotspot that stretches for 22km from the Millennium dome to the Houses of Parliament. Anyone on the river or its banks can now whip out a laptop and start browsing. Bored of the view from the millennium wheel? Watch that hilarious video of a woman falling over on Youtube instead.

The River Thames hotspot works by mesh networking 100 access points, allowing users to connect to the net without interruption as they travel down the river. It comes at a cost, even if fairly inexpensive, and anyone with a wireless enabled device can connect for 2.95 for an hour, 5.95 for a day or just get a whole month for 9.95.

This gigantic hotspot seems insignificant however in comparison with the one being developed in Taipei, capital of Taiwan. Taipei has been engaged in a huge infrastructure upgrade that will be the foundation of a city wide broadband hotspot that will literally turn the city into one great bit hotspot. However the best laid plans for this city wide project have not gone as well as hoped, with only 30,000 or so subscribers to the service, far less than anticipated. This is partly due to a perceived unreliability in the network as well as abundantly available free hotspots in cafes and other such places within the city.

However while it may take a while for the city wide hotspot to catch on, it does seem like these gigantic wireless projects will be the way of the future. The growing integration of high speed internet into every aspect of our lives makes it inevitable that the infrastructure will be utilised - if not now then soon. Like many new technologies the factor seems to be cost- how many people will really want to pay to use the internet for a hour while they travel between a work and home where it is already paid for. How many people are really that anxious to be online at all times? When the costs match the needs is when we will start to see the full potential of such grand schemes.

Fix Wireless Network Connection

With the development of wireless networks this means that no matter where you are as long as you are in contact with a hotspot you can check your emails or surf the net wherever and whenever you want. However although it is a great system it can have its problems also and one of the most common ones faced is a loss of internet connection. In this article, we will go through some of the stages that will help to fix a wireless network connection when it suffers a problem.

In many cases because when you are out and about with your laptop you will not actually have access to the hardware for the network you are connected to. Therefore, the only way you will be able to rectify this connection problem is with your laptop itself. Generally, within a matter of minutes you will be able to get the connection back that you have just loss.

However it is important to remember that when ever you are trying to rectify a fault on your laptop or PC and not just the network connection you do it one step at the time. You also only make one change at the time on it or you could end up in a much more serious position than you are in currently. Also by changing, things one at a time it actually helps you to quickly discover what works and what does not. This you can then note down and use in the future if you need to.

Step 1 - You know that you have the right hardware installed on your PC or laptop in order to connect to the internet but you can not actually work out why it is not connecting. What you need to do is go into the control panel on your PC or laptop and then go into network connections.

Step 2 - Upon doing this you will be shown a window on the screen in front of you, which shows you the possible network connections that are available for your laptop or PC. On this screen, you will see an icon saying wireless network you need to move the cursor over this and right click on your mouse. A list of different options will come up and you need to highlight and then click on properties.

Step 3 - If all seems okay then you need to come out of here and then click on the icon again with the right button of the mouse and this time select repair. What this does is actually severs any connection you may currently have with the network and will then try to re-establish it once more. The connection it makes will either be to the current network you have been using or to one which has much better connectivity.

However when it comes to a person trying to fix wireless network connection if they discover that this does not rectify the situation the only other choice they may initially is to actually reboot their PC or laptop. But you don't need to shut your machine off completely all you need to do is restart it and hopefully you may find that this is all it takes in order to rectify the problem.
