How to Connect a Wireless Router

When connecting a Wireless Router to the Internet and to provide a WLAN (Wireless Local Network) for local connectivity, it is important that you firstly have a working Broadband DSL connection to the Internet via a DSL modem. A lot of non-technical people get confused about the difference between a wireless router and an Internet Gateway Router, which has a built-in modem and so does not need a standalone DSL modem.

Let us assume you already have a DSL Modem and you have tested connectivity to the Internet through the modem with a PC. Now we need to connect the wireless router to the DSL Modem and also set up the local Wireless LAN to enable local devices to connect wirelessly with the device. If you have a cable modem, because your broadband service from your Internet Service Provider is a cable service then the setup is very similar, having already tested the functionality of the Cable Modem. In order to connect to the wireless router, your PCs, Notebooks or even Gaming Consoles need to support the IEEE 802.11 wireless standards. In other words they must have a wireless NIC card either built-in to the Motherboard or you will need to purchase a wireless adapter, the most common being USB Wireless Adapters which are largely Plug and Play.

Another important thing to remember when purchasing your wireless router, is to make sure it is not a wireless access point, otherwise it will not have the routing function which essential to connect your wireless devices to the Internet.

We are almost ready to start connecting our wireless device, so it would be a good idea to have a copy of any setup instructions that came with the device. They will be very similar, regardless of the manufacturer, but there will be subtle differences.

Switch off or unplug your existing DSL Modem or Cable Modem. If it is a DSL Modem then it will be connected to a telephone point with a supplied telephone cable, usually via an ADSL filter. Next take the network cable supplied with your wireless router and plug one end into the RJ-45 receptacle on the DSL Modem (there will usually only be one). Connect the other end of the cable into the WAN port on your wireless router. Most wireless routers also have 4 ports to enable you to connect 4 separate PCs via cables. The WAN port is normally distinct from the computer ports my means of colour coding or due to the fact that it is separate from the other 4 ports.

The next step is to plug in and switch on the DSL Modem and wait few minutes to enable it to boot and then synchronise with the Service Provider network via the telephone cable. Your DSL Modem will normally have a visible LED indicating a successful connection to the Internet.

Now switch on your wireless routing device that you previously connected to the DSL Modem, and shortly a green LED will normally indicate successful connection to your Modem. We are now almost ready to start configuring the Wireless Router itself.

Use a network patch cable to connect a working PC to one of the usually 4 network ports on the wireless device. A built in DHCP Server in the wireless router should allocate an appropriate IP Address to the PC being used for configuration. Open up a browser window on your PC and type in the URL provided by the manufacturer in the address bar. For example Linksys routers normally use the URL http://192.168.1.1 . Success should result in the router default configuration page becoming visible in your browser window. Your router instructions should give you the default username and password required to access the main wireless router configuration. This will often be admin and admin, or whatever your router instructions informs you. Once you have successfully entered the Username and Password, then navigate to the section that allows you to change the settings and configure an admin Username and Password that you can remember. Save the settings!!

You should now be able to test the connection to the Internet by disconnecting the cable and connecting to the wireless network by using your PC wireless connection. Bring up a browser window and try connecting to a favourite website, maybe a search engine like Google. If successful then the final step is to secure your wireless network by configuring wireless security settings, normally WPA or WPA2.

Either via your wireless connection or by reconnecting the cable between the PC and the wireless router, navigate back to the wireless router’s default configuration page and find the wireless security settings section. You will be required to configure the SSID of the wireless router. Your router will have a default SSID, but you should change it to a name that you remember. When you or your family are trying to connect a PC to the wireless router in the future, this name will ensure they attempt to connect to the correct wireless network instead of a neighbours network. Now select WPA or WPA2 settings from the configuration (WPA2 is more secure, if available). Configure a unique pass phrase that you can remember and the wireless router will use this pass phrase to generate a secure network key that is used to authenticate devices and to encrypt data passing over the wireless network. Remember to save this configuration again.

You will now need to reconnect your wireless enabled PC to the wireless network and you will be asked for the same pass phrase when your PC attempts to connect to the wireless network with the SSID you configured earlier.

If no mistakes have been made then you should now be able to connect to the Internet from the wireless enabled PC. Any other PCs that require wireless access just need to be configured with the correct SSID and pass phrase and connectivity should be quick and efficient. Good Luck.

Introduction to Wi Fi Technology And Its Advantages

Today one of the most discussed technology terms is “Wi-Fi”. People like to associate Wi-Fi with internet that is working in a wireless network. But the technology is offering more than just browsing the Internet. I have to say that Wi-Fi technology enables us to use Internet wherever we are. If we are in the office, cafeteria, cinema hall or in an airport, we can use Internet without any interruption.

What is Wi-Fi?

Wi-Fi is technically a trademarked brand name for the wireless standard owned by the Wi-Fi Alliance. Wi-Fi uses radio waves to transmit data. Like television connection from providers like Charter Cable, communication across a wireless network is a two-way radio communication. With no physical connection between sender and receiver, Wi-Fi technology works on a frequency within the electromagnetic spectrum associated with radio wave propagation. Some fifteen years before we didn’t even thought about the possibility of listening music or downloading music when we are travelling. Wi-Fi has made it possible for us to do whatever we want to do with Internet.

The applications supported by Wi-Fi include video game consoles, home networks, mobile phones, certain operating systems and other consumer electronics. That means, if you have a Wi-Fi connection, you can wirelessly download photos, music, videos from your computer to your compatible television. You can also access data from blue-ray player and certain other devices. Isn’t it sounds interesting?

With the introduction of Wi-Fi enabled devices, wired devices are becoming an old story. Nowadays people are more interested in buying Wi-Fi enabled devices. Some of the advantages of Wi-Fi are –

Improved mobility and flexibility – The technology provides you more flexibility in using your electronic devices. Now you don’t have to worry about the four to five cords that interconnect your devices together. WiFi can connect all the electronic devices, which is the next higher level of connectivity, without sacrificing design options. By having a WiFi connection to products like network music player, you can hear music wherever you are in the house. The only thing you have to do is to connect your music player with speakers located at different locations. There are options to change the music while you are in one room and the music system is in the other room.

Easy to setup connection – Though the term “Wi Fi” sounds really technical, it is not difficult to set up a wireless connection. It’s a pretty straightforward process. As you don’t have to drill any hole to run the wires, it’s much easy to install the connection. Most of the routers available with Wi-Fi are ‘plug and play’ connection. By just connecting to a power outlet or Ethernet cord, your Wi-Fi network is ready to use. Now you can connect your electronic devices to the wireless connectivity and enjoy the service.

Fast data transfer rates – The fastest commercially available Wi-Fi protocol in today’s market is 802.11. It can give a transfer speed of nearly 150 megabits. Along with this lighting speed, it can deliver streaming high-definition TV signals and CD quality audio. When certain Internet-ready devices can give you specific information like weather, sports or news, certain high end smart televisions and several other blue-ray players give you a fully functioning web browser almost similar to the ones you will find on computers.

Some of the disadvantages of the Wi-Fi connection can be security concerns and interference with other devices. If you are a person who is not that much worried about these disadvantages, then you can think about Wi-Fi as a modern alternative to networks that use cables. Wi-Fi can improve the usefulness of home computers and office computers. Think and plan about a Wi-Fi connection.

A First Timers Guide to Mobile Broadband

If you aren’t particularly tech savvy, the term “mobile broadband” may not mean much to you. However, it is likely that you have had at least some experience with it. When you purchase a computer or modern smartphone, there is usually a Wi-Fi card built into the unit. This allows you to surf the Internet wirelessly from the device and is in fact, how most people use the Internet these days. However, another method of accessing the Internet is via the aforementioned mobile broadband, which is simply a marketing term created by wireless carriers because they didn’t want to use the simple words “Internet Access.” Mobile broadband was first launched in 2002, with a standard for all GSM (Global System for Mobile Communications) put in place in 2008.

You may notice that you can access the Internet on your smartphone without even having the Wi-Fi enabled on the device. This is because your phone has a broadband plan that allows you to surf the Internet. All mobile carriers have their own broadband plan. You can find out the specific coverage areas by contacting your local carriers.

As for computers, the principal is the same. You may have noticed that if you don’t have a wireless router set up in your home, accessing the Internet can be a hassle. Maybe you cruise from cafe to cafe, searching for a location that offers that attractive “free Wi-Fi” advertisement. It’s also likely you spend time searching wireless accounts around your home neighbourhood, hoping to find one that isn’t password protected. The good news is that mobile broadband isn’t just for phones. You can purchase a mobile broadband card from a specific carrier which plugs directly into the USB or modem port on your computer. Once plugged in, there is no hassling with a router or encryptions: you are ready to surf the net.

Convenience and quick access to the Internet are major selling points to mobile broadband. However, like any service, there are drawbacks as well. Because there are so many mobile broadband carriers, the quality can vary from company to company. Some carriers may have more limited service areas than others, and some might have hardly any viable service areas at all. You’re obviously going to want a broadband plan that offers extensive coverage. The price for broadband plans and cards will also vary from carrier to carrier, so it’s important to find out as much information as possible before you sign up or buy that card. Mobile carriers offer various broadband plans. Whether you are extremely budget conscious, or you have the means to splurge on an extended plan, your mobile carrier should have a plan that fits your needs and budget.

All in all, mobile broadband is an ideal choice over the standard wireless because it eliminates a lot of the hassle, such as a router and user account setup. As this service is so quick and user-friendly, this helps makes it ideal for the less technologically inclined out there. All you need to do is purchase a card or plan and you will be surfing the Internet in no time.

Evil Twins And WiFi Hotspots

Public WiFi hotspots are available all around us. We use them because they are convenient. However, nearly all WiFi hotspots are completely unprotected , and are easy targets for hackers looking to steal your sensitive information.

Evil twins appear to be normal public WiFi hotspots, but they are actually set up by hackers to steal your information. When you inadvertently access an evil twin, the hacker who designed it can steal all the data you send over the Internet, including your password, financial data, and other personal information. Evil twins can even impersonate well-known websites when you access the Internet, in order to steal your login information.

If you accidentally connect to an evil twin, you may be subject to a Man-in-the-Middle attack, which occurs when a hacker eavesdrops on your Internet connection and intercepts any data coming into or out of your computer. You may be a victim of a Man-in-the-Middle attack if a formerly secure website (one that uses https) no longer is secure, you receive a warning message that the website’s certificate is no longer valid, or if the website looks and behaves differently. Below are some things you can do to stay safe from evil twins:

Wi-Fi Protected Setup For Wireless Network

What is Wi-Fi Protected Setup (WPS)?

Wi-Fi Protected Setup (WPS) is a standard for easy and secure wireless network set up and connections.

To use WPS, your product must support WPS and be compatible with WPA security. WPS can automatically set up a random network name (SSID) and strong WPA wireless security for wireless routers, access points, computers, adapters, Wi-Fi phones, and other consumer electronics devices. Some Wireless-G routers may not have WPS feature.

NOTE: The Wi-Fi Protected Setup configures one device at a time.

Advantages of Wi-Fi Protected Setup :

Wi-Fi Protected Setup automatically configures the network name (SSID) and WPA security key for the router or access point and for wireless devices that join the one can guess your security keys or passphrase because they are randomly do not need to know the network name and security keys or passphrases to use Wi-Fi Protected Setup to join a wireless network.

Disadvantages of Wi-Fi Protected Setup :

Unless all the Wi-Fi devices on the network are Wi-Fi Protected Setup -compatible, you will not be able to take advantage of the ease of securing the technology is fairly new, so not all wireless equipment supports Wi-Fi Protected your wireless device does not support Wi-Fi Protected Setup, it can be hard to join a network that was set up with WPS because the wireless network name and security key are random sequences of letters and numbers.

There are three methods on how to connect using Wi-Fi Protected Setup.

Method 1: Connecting a Device using the WPS button:

Use this method if your client device has a Wi-Fi Protected Setup (WPS) button or if it prompts you to press the WPS button on your router.

Locate and press the button on your router. Within two minutes, click the WPS button on the device you want to connect to the router’s wireless network. After the device has been configured, click Close.

Method 2: Connecting a Device using its WPS PIN

Use this method if your client device has a Wi-Fi Protected Setup Personal Identification Number (PIN).

Open the setup page of your router. Click on the Wireless tab, then select the Wi-Fi Protected Setup radio button.Enter your client device’s PIN on the appropriate field then click the Register button. After the client device has been connected, click OK.

Method 3: Connecting a Device using the Router’s WPS PIN

Open the setup page of the router. Click on the Wireless tab, then select Wi-Fi Protected Setup radio button. Take note of the router’s WPS PIN. You may find the Router’s WPS pin on the back of the router also. When your device prompts for the router’s WPS PIN, enter your router’s unique PIN. After entering the PIN, follow the onscreen instruction for your device.

What is a Wireless Router

The majority of households in the UK, Europe and the US will have a connection to the Internet, and in most cases will have a device known as a Wireless Router to provide that connectivity for at least 1 computer device. In most cases the Wireless Router will be used to connect multiple devices from a local WLAN to the Public Internet.

Before we specifically describe a Wireless Router, it is probably best to describe the role of a Router in a data network. A Router’s role is to read the logical IP Address on packets and determine which network or sub network those packets need to be delivered to. A simple way to look at a router is to compare it to a postal sorting office where letters have their post codes or zip codes checked to determine which area of the country the letter is destined for. In the UK, the first part of the postal code determines the general area such as an area of London or Manchester, and the second part determines an actual street or road. An IP Address, when coupled with a network mask does almost the same thing, but instead of a Geographical area, the router is able to determine a specific area of a network.

A local router which is attached to a Local Area Network or Wireless Local Area Network acts as the local postman by determining the physical MAC Address of a device so that it can deliver packets to the correct computer device.

In order to connect to the Internet we normally need a modem that runs the same protocols as the Service Provider Access Network. In most cases we will be using either an ADSL Modem or a Cable modem depending on who our service provider is.

A wireless Router will normally combine the functions of a modem, a router and a wireless access point, and provide not only wired connectivity to local devices by means of an Ethernet cable, but also provide the option of connecting to local devices by means of a wireless technology specified in the IEEE 802.11 Wireless standard. The IEEE 802.11g standard allows for local wireless connectivity at 54Mbps within the 2.4Ghz ISM frequency bands. The IEEE 802.11n standard was ratified in 2009 and provides for enhanced data rates up to 300 or even 600Mbps and incorporates the MIMO ( Multiple Input Multiple Output) technology which requires the use of additional antennas. The channel width is also doubled from 20Mhz wide channels used with previous versions of the standard to 40Mhz. Routers running the 802.11n standard with MIMO are normally a little more expensive due to the cost of the additional antennas.

The home Wireless router will also act as a DHCP (Dynamic Host Configuration Protocol) Server, so that local IP Addresses can be automatically served up to local computer devices, doing away with the need to manually configure IP parameters on each an every local device. Another protocol running on the wireless router with be NAT (Network Address Translation), which translates locally routable IP Addresses to Globally routable IP Addresses needed on the Internet. This means we can all use the same local IP Addresses on our LAN or WLAN to communicate locally, but use the Global IP Address supplied by our Service Provider when accessing the Internet. The router translates from local to global on the way out and the reverse as packets are routed towards the local network needs a degree of security, particularly when connected to the Public Internet, otherwise anyone globally could have access to your network. The router will provide this security by having a built-in Firewall function. Wireless networks have additional security issues because of the fact that anyone within range of your wireless network, who has a wireless access point or device could join the network and therefore eavesdrop on data conversations, or worse still access a computer device and steal or corrupt information. For this reason a number of Wireless security protocols have been developed to protect the WLAN.

The first wireless security protocol was WEP (Wireless Equivalent Privacy) which uses an Authentication and Encryption key normally of 64 or 128 bits in length to protect the data as it traverses the wireless lan. WEP keys can easily be broken by someone determined enough to do it and programs are freely available on the Internet for this purpose. For most home users WEP may be sufficient, but as you don’t necessarily know who your neighbours are and their intentions, it is better to protect your local wireless network with a more advanced security protocol. WPA (Wi-Fi Protected Access) uses much stronger encryption than WEP and should be used in preference to WEP when necessary. It is important to note that most wireless routers come packaged with wireless security turned off, so it is up to the consumer to determine the level of security required and to configure the parameters when originally setting up your WLAN. If you are not technically minded then find a friend of relative that has some knowledge and choose the strongest protection available on the device, which will normally be WPA.

What Advantages Are There From Using Network Cables Instead of Going Wireless?

With the rise of wireless networking technology, more electronic devices are being built with this specifically in mind. What is the future for data cabling? Should you go wireless?

Due to the flexibility of wireless networking it can be advantageous, but data cabling still has plenty of key benefits.

If security is important to you data cabling is the way to go. Gaining unauthorized access to a wireless network is far easier. If you are on wireless you have controls like password protection, but it is still quite vulnerable.

Another big issue for wireless networks is interference from other radio sources. With the shielding on traditional data cabling this is very unlikely to happen.

You can expect to remain constantly connected to the network when data cabling is used. Wireless is prone to momentary lapses in signal, or interference from outside frequencies as mentioned above. This can prove highly inconvenient, especially while data transfer is being performed, potentially severing download connections. It can also affect data transfer rates and can lead to unacceptable corruption of files. Anyone who uses wireless regularly will be familiar with the experience of finding after a long download that the file has been corrupted. Cabling allows for a far more robust connection and eliminates these kind of worries.

High speeds are also a great function of physical cabling. You can achieve speeds of up to 10 gigabits with modern data cables. For the highest speeds consider fiber optic cabling which can also cover longer distances with a loss of speed.

Where wireless networking really comes into its own is in mobility. They offer excellent mobility, especially for portable devices, due to the fact that there are no physical wires to restrict their movement. However, users must always remain within range of a transceiver and must be directly connected to a cabling system to use data transfer possibilities.

It remains a fairly straight forward process to expand your network using cabling. All you need to do is add a hub to the existing network and then running a cable to the new hub. You can expect to run anything up to 255 devices from the same router or hub.

So while wireless has its perks there is still a lot to be said for network cables. Reliable, fast and secure it will take some serious advances in wireless technology to see traditional cables become obsolete.
