    Comparison of Wireless-N Notebook Adapters

    Nearly all of the wireless-N adapters on the market today connect through the USB port of your computer. Small and easy to install, most basic adapters are less than $50, as of November 2012. Dual-band adapters can be twenty to thirty percent more, but are capable of faster speeds if they are used with compatible Wi-Fi access points. If you are looking for an adapter to be used at your home or office, look at the manufacturer name on your Wi-Fi access point before purchasing an adapter, as faster speeds may only be available when both are made by the same company.

    Activating Your Wireless LAN on Your Sony Vaio

    A Sony Vaio can connect to a wireless access point on a wireless network, allowing you to use the Internet or share files with other computers. Your Vaio can also connect directly to other computers using an ad-hoc network.

    iPhone to Router Connections

    In most cases, connecting to a Wi-Fi router is just a matter of knowing the router's name and the right passcode. If the router is set up to accept connections only from trusted devices, your iPhone will have to be added to that list by the router's administrator before you can access Wi-Fi. As with a computer, accessing a Wi-Fi network can compromise your data. If you set up your own router, it's best to use the router's encryption options and set a password to prevent unauthorized access.

    How to Program the Dish Network Remote

To operate your TV set and other devices with the Dish Network remote control you must pair the remote to the device with a specific remote code. The basic Dish Network remote can operate just your TV set, while the more advanced platinum remote control will pair with a range of other devices, including VCRs, amplifiers and cable set-top boxes.

    How to Purchase a Wireless Signal Booster

    Wireless signal boosters take the signal from a wireless router and repeat it for enhanced coverage. Whether you're up in the attic above the second floor, down in the basement or in the farthest reaches of the yard, repeaters can bring the signal closer to you and your Wi-Fi-capable device. When purchasing a wireless booster, keep key features in mind to make installation and daily use easier.

    How to Tell if Someone Is Stealing Your Wi-Fi

    Most routers use dynamic host configuration protocol to automatically assign Internet protocol addresses to each computer that connects to the Internet through the routing device; the IP address enables the router to tell PCs apart. If your Wi-Fi network is unprotected, intruders can sign on to your network and leech valuable bandwidth, causing data transfer speeds to slow to a crawl. If you're experiencing poor network performance, you can check the DHCP client table on your router to see if someone has connected to your Wi-Fi network without your permission. The DHCP client table lists each device on the network that's been assigned an IP address.

    How to Improve Speed of a Slow Wireless Network

    Although slower and less secure than a traditional wired Internet connection, there's no questioning the enhanced freedom and flexibility a Wi-Fi connection affords. However, there are numerous appliances and construction materials in your home that are more than happy to block your wireless bliss. Additionally, improper placement and settings of your wireless router can prevent maximum performance. Making free or inexpensive tweaks to your router and following simple placement tenets often make dramatic improvements to wireless network speed.

    How to Identify a Wireless Connection

    Each wireless Internet connection has a set of properties including information on the wireless adapter, the amount of data passing through the connection and the IP address, among others. Gathering this data is useful when adding a new network device, troubleshooting an intermittent connection or creating a brand new network from scratch. This information is accessible through your computer for ready access whenever you need it, enabling the fastest connection your hardware supports.

    How to Recover a Lost Network Key for a Linksys Router

    The same network key that keeps intruders out of your wireless network also excludes you if you lose the key. However, by establishing an Ethernet connection with the Linksys router, you circumvent the need for the wireless network key and gain access to the network. With network access, you can enter the Linksys setup utility and locate the network security key. However, this utility requires a different password. Things get more complicated if you forget the administrator password, because you then have to reset your router, which erases all your previous settings.

    How to Obtain a Lost Network Key for a D-Link Wireless Router

    The D-Link router’s network key secures your wireless network from unauthorized entry. Failure to enter a valid security key denies access to the wireless network and prevents deciphering of network-transmitted data. If you’ve lost your security key, this protection works against you by locking you out of the network. However, establishing a wired connection directly with the router allows you to retrieve or reset the security key. Access to these settings requires a different, administrator’s password that grants access only to the D-Link setup utility. If you’ve also lost this password, your only recourse is resetting the router.

    How to Find My Network Key for a Wireless Router

    A wireless router makes it easy to turn on Wi-Fi capable computers in your home or office and connect to the Internet without needing to worry about cumbersome or unsightly cables. Most wireless routers are compatible with common DSL or cable broadband connections and relatively simple to configure. With a single wireless router, you can create a Wi-Fi network capable of providing Internet access for all the computers at your location. One drawback with Wi-Fi networks is the possibility of intrusion by a hacker or other unauthorized user if not secured with a network key. If you forget the network encryption key and need to connect additional computers to the Internet, you must retrieve it from the router's control panel interface.

    How to Buy Wireless Devices to Create a Network

    A wireless network allows you to avoid running cables and lets you use mobile computers like laptops anywhere in the house or office. To take advantage of these benefits, you have to set up a wireless network using radio waves to send and receive signals to and from each piece of equipment. Some mobile devices will already be capable of working wirelessly. Most modern computers come with wireless adapters included, as well.

    How to Find a WPA Key on a Wireless Network

    The Wi-Fi Protected Access security key is essentially the passphrase used to access the wireless network. This isn't technically accurate, because the key uses a hexadecimal format that is internally calculated from the entered passphrase. However, because this key is calculated behind-the-scenes and is directly related to the passphrase, most users and router manufacturers describe the WPA key and passphrase synonymously. For the purpose of finding a network key, the passphrase will indeed suffice. This passphrase is stored in your router's administrative utility, to which a wired connection is required if you cannot access the wireless network.

    How to Change the Name of a Wireless Network

    A wireless network's name is called the Service Set Identifier, or SSID, and can be up to 32 characters in length. By default, most wireless routers configure the SSID based on the router's name or manufacturer. This allows would-be hackers to fine-tune their efforts to your particular router. You shouldn't give potential data thieves this information, so changing your SSID removes that possibility. At the same time, a unique SSID name removes network confusion when numerous networks exist that share similar names.

    How to Connect to an FTP Site

    File Transfer Protocol is a method of transferring data over a network. An FTP connection is often used to upload or download files to a remote Internet server. Some servers permit anonymous access and allow anyone to connect and view stored files. Other servers require a username and password and limit FTP access only to authorized users. Both anonymous and authenticated FTP connections can be set up using Windows or a standard Internet browser.

    How to Find My IP Address

    Your computer's IP address is the specific address assigned to the machine when it connects to the Internet or a local area network. In most cases, your computer -- or router if connecting through a LAN -- receives an IP address from the Internet service provider when it connects to the Internet. For most users, this addresses changes each time they connect, while others have a static, or permanently assigned, IP address. Regardless of if you use a dynamic or static IP address, there may be times when you need to know the value. For instance, if you want to allow someone to connect to your machine remotely or want to run a personal mail or Web server, knowing the IP address of your router or computer makes connecting much easier.

    How to Access a WiFi Antenna

    To detect and communicate with a wireless router, a computer needs a Wi-Fi card. The Wi-Fi card features a pair of antennas that both broadcast and pick up wireless radio signals, enabling a PC to detect Wi-Fi hot spots in the area. As long as wireless communication is enabled, connecting your computer to the Internet takes just a few steps; Windows will automatically detect wireless networks within range.

    How to Reset a NETGEAR to Factory Conditions

    NETGEAR produces a wide variety of Wi-Fi routers and access points that enable you to extend your wireless network by adding additional computers to a single Internet connection. Setting up a NETGEAR wireless access point or router requires that you access the device's configuration page via a Web browser. After you've logged in to the configuration page, you can set options for the device and hook it up to your broadband connection so that you can share Internet access on the network. However, if you change the default username, password or IP address for the NETGEAR wireless device, you may not be able to access configuration settings for the router or access point if you forget the new values. If this occurs, you can perform a hard reset to restore the NETGEAR device to its factory default settings.
