Once logged in, you can purchase the required amount of bandwidth via the secure, credit card purchase, facility.

What is line speed?

Line speed is the rate at which data can travel along the Telephone line and is usually measured in bits per second or b/s or bps.

What is a bit?

A bit is the basic unit of information in computing terms and is the amount of data stored by a digital device. There are 8 bits in 1 byte. In computing terms a small b denotes a bit and a capital B denotes a byte.

What is Data Transfer Rate (DTR)?

Data transfer rate is the speed at which data can be transmitted between different devices, this is also known as throughput. DTR is usually measured in Bytes per second or B/S or Bps.

What is the difference between Line Speed and DTR?

The distinction here is bits per second and bytes per second. Your internet connection speed is 1024 kbps (minimum for ADSL) (note the small 'b'), which is 1024 kilo bits per second. There are 8 bits in a byte, which is how most applications will report how they're downloading. So 1024 kbps is equivalent to 1024 ÷ 8 which is = 48 kBps (kiloBytes per second). In this case, note the large B to denote BYTES.

Your internet connection of 1024 kbps is raw bandwidth. Every time you make a connection, there is supplemental information sent and received. These are generally protocol specific headers / additional information (e.g. TCP headers / HTTP headers) and they add overhead to the overall communication, reducing (normally only by a small amount, but still reducing) the total amount of bandwidth you have available for raw downloading of data.


How do I check my connection speed? (Speed Test)

You can go to and select speed test or by directly clicking on this link

 How do I secure my Router?

Sometimes we ignore little details, which is a bad thing - because others can use our negligence against us. Most routers and ADSL modems come with a web interface that is used to control and configure the device. The administration panel is accessed with a web-browser, and it provides access to data such as:

  • Your user name and password.
  • A log that shows which sites are visited, which network hosts are connected to the router.
  • Port forwarding rules.
  • etc.

There are two things that have to be done if such a device is used in your household:

Follow up:

  1. Change the default admin password to another one. Don't worry if you forget it. You will either not need it in the future because routers and ADSL modems are often the "configure and forget it" type of device; even if you forget the password and you need to reconfigure the device - you can reset it to the factory settings, because you have full physical access to the device;
  2. Disable administration via the Internet. It is likely that you won't ever need it. Even if you do, you can do it much safer with a SSH tunnel to one of your computers and then connect to the router locally.

How to do this?

  1. Log on to your router or modem using the web-browser, usually it is done by opening this page in the browser: or
  2. Authenticate by typing the administrator name and password. For Billion_800VGT, the name is usually "admin", and so is the password.
  3. See what the available options are, if you are not sure what you are looking for, scan through all the tabs and look for labels such as "configuration, password", "security", or "remote administration", etc.
  4. Once you've found the right section, change the password to another one, and then disable remote administration.
Here are a few examples that apply to the Billion 800VGT

Even though the devices are different, you can see you can fined it under the configuration like in this case it is under configuration ,system under remote access and user management I you can not fined it on your own you can consult the user manual of the modem for assistance. Once you've made the changes, do not forget to apply them.

How to verify if it really works?

Your router or modem has two addresses, one of them is the local address (in the first example the address is (, the other one is the external address (you can find what it is by opening in your browser).

The local address is used by the router to communicate with your computer, while the external address is used for world-wide communications, i.e. other computers on the Internet. If remote administration is allowed, it means that anyone in the Internet can log on to the device and configure it. In contrast, if remote administration is disabled, it means that only computers from your local network (i.e. those that belong to you, located in your household) can configure the router.

  1. Find your external address by opening
  2. Open http://local-address/, then http://external-address/
  3. If in both cases you are able to access the administration panel of the router, it means that remote administration is enabled. Otherwise, if it only works locally - you're ok.

Why do this in the first place?

If remote administration is enabled, and you are using a standard password such as "11111" or "admin" or "12345" - a remote attacker can get in control easily. Here are some examples of what can be done with that:

  • The attacker could also 'borrow' your credentials and use your Internet account (i.e. the traffic and bandwidth for which you pay).
  • The password of your Wi-Fi network can be obtained. Most of us use the same password for more than one account; what are the chances that your WEP or WPA key matches your mailbox password, or the one you use for banking?
  • Your Wi-Fi network can be reconfigured not to use encryption, which means that others will be able to use it for things such as sending out spam or conducting DoS (denial of service) attacks against other computers.

The possibilities are only limited by the creativity of the attacker and by their skills.

How can I speed up my browsing on a dial-up modem?

You can make use of our proxy server ( port 8080).

How do I cancel my Telkom Internet account?

For Telkom Internet Dial-up Services and ADSL cancellation contact 10210, for any other Internet-related service cancellation contact 10210.

What is the dialling number for my nearest POP?

Dial 0860 007 249 (at local call rates).

How can I get Windows to save my dial-up password?

If the dial-up client for Microsoft Networks or Microsoft Family Logon (Win98 only) is installed Windows will prompt you to log in after Windows starts. If you do, you will be able to check a 'Save Password' box on the Dial-Up Networking 'Connect To' window. Once a connection has been established, windows will retain your dial-up password. Remember, you must log in to Windows initially for this to work.

My Computer dials-up by itself, what can I do?

Some programs, such as antivirus software and chat clients, sometimes attempt to connect to the Internet while unsupervised. To prevent this:

  • Disable the Save password option. Without the password, the program will not be able to connect.
  • Check to see if your antivirus program has an option to make it prompt you before it dials-up your connection.
  • Choose to Never dial a connection in Internet Explorer's dial-up settings, and just make a shortcut to the Telkom Internet. Go to My Computer, Dial-Up Networking. To make a shortcut just right-click on the Telkom Internet icon and then click Create Shortcut. Use the shortcut to connect to Telkom Internet instead of connecting through Internet Explorer.

How can I remove my .PWL files?

.PWL - Pass Word List - files contain passwords and other secure bits of information remembered by Windows. Sometimes, these get corrupted and the 'Remember password' option in Dial-up Networking malfunction or DUN 718 and 645 errors can occur. To remove the .PWL files:

  • Click on Start, Find or Search, Files or Folders
  • Type *.pwl in the search box and select the (C:) drive in the "look in" field
  • Click the Find now or Search now button. Windows will search your hard drive for any file which ends in .pwl. A list of these files will appear in a search results window.
  • When the search is complete, right-click on each file listed in the search results window and choose Delete and if prompted, choose Yes
  • When all of the listed files have been deleted, close the search window.
  • Reboot your computer by clicking Start, Shut Down, Select Restart, click OK
  • Once Windows has restarted, you will be prompted for a username and password. Type anything for the username, but leave the password blank.
  • Click OK
  • Your .PWL should now have been recreated, uncorrupted.

I get disconnected when I check my email on dial-up, what do I do?

You're probably using Outlook Express. If so, there is a setting in OE that disconnects you after you send or receive mail. To change the setting in Outlook Express:

  • Click on Tools at the top of the screen
  • Click on Options
  • Click the Connection or Dialling tab
  • Uncheck the box next to Hang up after sending and receiving
  • Click Apply
  • Click OK

If this does not do the trick, try the following:

  • Click on Tools at the top of the screen
  • Click on Accounts
  • Click on the Mail tab
  • If there are multiple accounts here delete any unused accounts
  • If an account is configured to use a connectoid that does not exist, it will disconnect the current dial-up connection. This may also occur if an account is set to dial some other dial-up connection than the current one. If any accounts have an entry other than Any Available listed under the Connection column:
    1. Click on that account to select it
    2. Click on the Properties button
    3. Click on the Connection tab
    4. Uncheck the box next to Always connect to this account using
    5. Click Apply
    6. Click OK

What is the difference between internal and external modems?

Both types have their advantages and disadvantages which have been listed below so you can decide which type best suits your needs.

Internal Modems

  • Advantages:
    • Less expensive than external modems
    • No external power supply required
    • Avoids the need to upgrade to a 16550 UART serial processor
    • Some are configurable by software
    • Some are 32 bit modems
    • Avoids cabling problems (loose connections, incorrect cables, etc.)
  • Disadvantages:
    • Installation and service more difficult (PC must be opened)
    • No indicator lights to show status of modem
    • Harder to share modem between multiple machines

External Modems

  • Advantages:
    • Easier installation
    • Can be shared between multiple machines (IBM or Mac)
    • Has indicator lights to show status of connection
  • Disadvantages:
    • More expensive
    • External power supply required
    • Requires extra cabling (usually supplied with modem)

I don't understand the differences between 56K dial-up modems?

There are several different 56k protocols on the market and this is what you need to know: X2 and K56Flex - These are essentially incompatible protocols that have competed for market share. They will connect with each other, but it is only possible to obtain a connection faster than 28.8 if the modems on both ends share the same protocol.

X2: U.S. Robotics developed X2, this protocol was released several months before k56Flex and as a result quickly gained a large portion of the market. K56Flex was developed in cooperation between Rockwell Semiconductor and Lucent Technologies, and was released a little later than X2. Despite the delay, many of the popular name-brand manufacturers bundled K56Flex modems with their systems. V.90 is the standard, released in spring of 1998, that allows all 56k modems to communicate with each other using the same "language".

Nearly all X2 and K56Flex modems are upgradable to V.90, and in many cases it is a free software upgrade. If you have an X2 or K56Flex modem and have not upgraded, contact the manufacturer of your modem to find out how to do this.

Why don't I get 28800 bps (or more) on my connection?

If you see a connection speed of 38400, 57600, or 115200, don't be fooled - that is the serial port speed between your computer and your modem, not the speed between your modem and the remote modem. To report the modem-to-modem speed, your modem probably needs a different initialisation string.
