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.

Scuba Diving In Thailand

The diving possibilities in Thailand are nearly endless. Thailand is listed as one of the top ten sites for scuba diving and it is not surprising why when one sees the world class scuba diving sites, clean white sandy beaches and crystal clear water. In fact, Thailand is the perfect place for it.

This beautiful country is full of history and culture. The Thais are friendly and hospitable while accommodation possibilities vary from budget to luxurious. There over 50 scuba diving centers located in towns and islands along the Gulf of Thailand and Andaman Sea.

Thailand offers a varied diving environment which ranges from deep underwater mountains to sheer rock formations rising above the sea, from coral gardens located in shallow warm waters to undersea formations created by granite boulders; and from limestone walls plunging deep into the sea to numerous dark caverns.

Thailand is blessed with both hard and soft corals. While diving one can often see large pelagic fish, whale sharks, silver tip sharks and manta rays. Thailand's scuba diving sites never fail to impress the most seasoned diver with its variety and species of tropical fish.

Scuba diving in Thailand takes place all year round. However, the best time of the year for diving in Andaman Sea and other diving sites is from October to June. During this period, the sea is calm and one can travel quite far into the sea in boats to enjoy the unique diving experience that Thailand has to offer.

Diving usually takes place in three areas across Thailand. One is Pattaya, which is quite close to Bangkok; the second place is the islands off the Gulf of Thailand. This includes the islands of Ko Samui and Ko Tao. The last place popular with scuba divers is the west coast of Thailand. Here Phuket, Ko Phi Phi and Krabi offer the best experience in the Andaman Sea.
