DSL & VOICE QUESTIONS AND ANSWERS
DSL Speed Differences Between Households
The rated maximum bandwidth of a DSL connection often cannot be reached. Additionally, actual DSL speeds vary between households. Factors affecting DSL speed include:
Quality of the phone line at your residence. Neighborhoods with better copper wiring can achieve somewhat faster DSL speeds.
Length of the phone line between the residence and the phone company hub (often called “central office”). DSL technology is “distance sensitive” because its performance decreases significantly as you get further away from this hub.
Service glitches. While normally a constant, DSL speed can suddenly drop if the service provider has technical difficulty with their network. Speeds should return to normal after a few minutes or hours.
Short of rewiring their residence, customers can do little about changing these factors. Other factors you can more directly control include:
Spyware on the computer(s). Even when the DSL network may be functioning at full speed, spyware programs may be consuming the bandwidth, robbing your
DSL speed. Anti-spyware programs should be run regularly on networks to prevent this problem.
Misconfigured wires or wireless router. Routers sit between your computers and the Internet connection. If not functioning properly, a router can greatly limit the DSL speed achievable on all computers. Temporarily connecting a computer directly to the Internet can help diagnose this situation.
Slow wireless network connection. In extreme cases, a very slow Wi-Fi connection between a computer and a wireless home network will not keep pace with the speed of the DSL Internet connection. Improving the quality of the Wi-Fi connection will solve this problem.
Old computer(s). Very old computers lacking sufficient processing power or memory cannot keep pace with a high-speed DSL connection. You can verify this problem by comparing the DSL speed between computers at the residence.
