Set Up Computer to Download Faster

Internet connections come with a specified bandwidth at which your computer downloads and uploads data. If you feel that the download speed of your Internet connection is slow, there are a few things you can do to make it run a bit faster.
If no tips and tricks work, you can always upgrade to a higher bandwidth Internet by paying a little extra to your Internet Service Provider (ISP).


Utilize the 20 percent bandwidth that Windows keeps in reserve for its own applications. That way, you will have full 100 percent bandwidth available instead of 80 percent that you normally get.

Go to "Start" and open "Run." Type "gpedit.msc" and click "OK." Navigate to the branch "Local Computer Policy" > "Computer Configuration" > Administrative Templates" > "Network" > "QoS Packet Scheduler" > "Limit Reservable Bandwidth." Double-click "Limit Reservable Bandwidth" and click the "Enable" radio button. Also, replace the "20%" value with "0%" within the same window.

Click "OK" and restart your computer.

And follow these steps also.

  1. Disable all unnecessary add-ons of your web browser. Add-ons can slow down the Internet connection speed, so you might see some improvement after disabling some of them. Open your web browser, go to "Tools" > "Manage Add-ons." This will contain a list of the enabled add-ons with option to "Remove" each of them. Keep the ones you use and delete the unnecessary ones.
  2. Install an Internet speed-optimizing software program that would maximize Maximum Transmission Unit (MTU) values, Receive Window values (RWIN) and registry keys for your Internet connection. Some of these software programs include SG TCP Optimizer, Active Speed and Speed Connect Internet Accelerator. All the applications work the same way.
    Once you install an application, it will automatically go to the registry and make the required changes to boost your Internet speed. You don't have to do anything at all.
  3. Contact your ISP and request to upgrade the bandwidth if none of the above tricks help you achieve the download speed you want. Let us say if the current bandwidth is 512 kilobits per second, you can upgrade it to 1 megabit per second.

Create a New Protocol in QoS

QoS, or Quality of Service, is a protocol used to provide a high level of audio or video reception. This service is meant to provide a near flawless delivery of signals so the person at the receiving end will not have delivery breakdowns, interference or dropped calls.

The traditional delivery method was "best-effort" such as email or data downloads. However, with new communication technologies offering new delivery features, "best effort" was not good enough. The predictability and guarantee delivery of a signal is important.

Fixing MagicJack.

Printing from Terminal Services

There are a number of ways to manage network printing in a Terminal Services environment. Within a small unit of an organization or division, the administrator might want to configure printers locally on the server running Terminal Services. The printers might be locally attached through the parallel port or a network interface. These printers are automatically available to all users on the system.

A user who wants to print locally to a printer connected to his or her own computer has the option of either using the Terminal Services client ability to redirect a print job to a local device, or using peer-to-peer networking.

How to Use a Networked Computer CPU

Networked computers have a variety of different configurations, some quite individual to the organization that installs the network.

How to Enable GPS in a USB Modem

Global Positioning System (GPS) is a navigational device that detects the location of several satellites in space to triangulate a specific location on the ground. A USB modem is a network device that one can plug into a USB port of a computer. USB modems do not have the hardware to detect the location of satellites. They do, however, connect to NID (Network Interface Device), which is a terminal that your Internet service uses to connect a user into the Internet. A user can track the location of the NID to determine their location.


  1. Connect to the Internet. This will delegate an IP address to the USB modem, and connect to the NID.
  2. Go to IP Trace (see Resources). This traces the location of the NID, less than 6,000 feet (1.1 miles) from your computer.
  3. Click on the blue text that reads "Click for big IP address location image," located in the map on the right hand of the screen. This will open a satellite image of the NID.

What is the Function of DSL?

DSL is a method for connecting to the Internet. It is a high-speed connection for desktop and laptop computers. DSL connections require a special modem and use your existing copper telephone lines. Before choosing a DSL provider, consider the price, connection speeds, and other features to ensure that you have the speediest connection possible.

Need for High-Speed Internet

When the Internet was first popularized, there was not much of a need for high-speed, "broadband" Internet connections. Users could check discussion boards, send and receive basic email messages and browse websites. These websites were relatively small in file size. However, as Internet technology has developed, the need for higher speed browsing has increased.

Select Internet Connection Methods

DSL is one of several Internet connection methods. Dial-up connections require the use of a telephone line and have speeds of up to 56 kilobytes per second. It is the slowest of methods. ISDN connection also requires a telephone line and a router and has connection speeds between 64 and 128 Kbps. Cable modems use a cable line to bring users between 512 Kbps and 20 Mbps. The most common connection are wireless connections, which have connection speeds of 30 Mbps.
DSL Connections

DSL, or digital subscriber line, uses the unused part of copper phone lines to send and receive data. It requires a special modem and an adapter card to connect to your computer. It connects with speeds between 128 Kbps and 8Mbps. The system does not interfere with your normal phone use, and its bandwidth if affected by the distance from the network. It has to be located within 3 miles of the phone company's switch.

DSL Types

There are four types of DSL connections: ADSL, SDSL, ISDL and RADSL. ADSL offers faster download than uploading speed. It's the most common connection. SDSL connections have symmetric download and upload speeds. IDSL is slower, as it provides a 144kb per second maximum connection, but is available at farther distances than other DSL types. Finally RADSL connections vary depending on the line's conditions.

Phone Cable Connector Standards

Telephone cable connectors use RJ-11 connectors to connect to the wall outlet. The book "Cabling: the Complete Guide to Network Wiring" states that the terms phone jack and phone outlet are often used interchangeably.

How to Find the MAC Address for a Xerox F12 Fax Machine

The great advantage it brings that it destroys bad settings that you might have done or might have accumulated with multiple upgrade etc. This is very likely to resolve many issues users encountered with opera user settings.

What should do before profile reset?

You need to backup your files so that you can get back your data.
How to do the profile reset?

Close opera. You need to locate your profile directory (Help>about opera will show you the exact location). In windows xp, it is commonly at c:\documents&settings>username>application data>opera>opera>profile and in win vista its under in Windows Vista C:\Users\yourname\AppData\Roaming\Opera. Note that "Application data" is a hidden folder in windows and you need to enable the opton to view hidden files and folders(open my computer>tools>folder options>view>show hidden files and folders).

Once you have found the folder, just find and delete the file opera6.ini(configuration settings). Restart opera and opera will rebuild the profile settings.
