Why are my speeds slow?
A. Line speed refers to how many bits per second your Internet connection can download. This is usually how your ISP represents your connection speed when you sign up with them. For home Internet connections, the speed is measured in kbps (thousands of bits per second) or Mbps (millions of bits per second). An example is a 512/128 ADSL plan, which can download theoretically at 512 kbps and upload at 128 kbps.
Q. What is download speed?
A. Your download speed is directly linked to your line speed. This is typically the speed you will see when you download a file in your web browser. It is measured in KB/s (Kilobytes per second) and MB/s (Megabytes per second), where one byte is equal to 8 bits. Therefore if you are on a 512/128 ADSL plan you can theoretically download at 64 KB/s and upload at 16 KB/s.
Q. What speed should I get?
A. The following table depicts the speed you should be able to obtain depending on your ISP, the type of connection you have, the plan you have chosen and the contention ratio of your plan. Your maximum speed may also vary depending on your distance from a telephone exchange, your line quality, the number of users in your area, or connection protocol overheads.
