Slow speeds on a DSL connection

Getting low throughput on your computer when using a DSL connection

  • Check how fast data is coming into the computer by running a performance test:

    1. Measure your throughput speed, the average rate of successful data delivery over a communication channel, by visiting the Speed Test at For "Speed Test Type" select F-16 Jets, and for "Speed Test Host" the closest server to your location.
    2. If the throughput speed is comparable to the DSL speed on your service plan, then the connection is receiving the full speeds, there is either an issue with your computer or the application you are using requires more speed than you have available. Call to inquire about faster speeds available.

  • Make sure that anything that uses phone service at your location has a DSL filter attached to it. This would include telephones, answering machines, fax machines, analog modems in computers, and satellite/TiVo receivers. Also, if you have an alarm system, you may need to check with your alarm company as a special DSL filter may be required. Your DSL modem SHOULD NOT be filtered.

  • Is more than one computer connected to your DSL connection? If so, another computer on the network may be using up your bandwidth. Try using the connection with only one computer turned on and see if the speed improves.

  • Is there any Dial Up software installed? Make sure to uninstall any Dialup software including accelerators and dialers. These can usually be removed through Add/Remove Programs of your Control Panel.

  • Is anything downloading in the background? Antivirus software, Windows Updates, file/music downloads may be using up the connection. Check your System Tray near your clock and disable these items. Re-run the Performance Test. Go to the Software page and run through the “5 Steps for Safe Computing” checklist. Make sure that you have the latest Windows updates, run an antivirus scan, as well as an anti spyware scan.
