    • Slow Internet connection If your Verizon High Speed Internet speed seems unusually slow, step through the checklist below to diagnose the problem.

    Figure depicting checkbox Run DSL Speed Optimizer. Are you tapping into the full power of your Verizon High Speed Internet connection? Use the DSL Speed Optimizer tool to help you determine if key settings (TCP/IP and MTU) are tuned for optimal performance. Learn more.

    Figure depicting checkbox Turn your modem off and then back on. Most Internet connectivity problems can be solved by turning the modem off and then back on again. Turn your modem off, wait 15 seconds, and then turn it back on. After waiting 45 seconds to allow the modem to synchronize with the server, try reconnecting to the Internet.
    • Note: If your modem doesn't have an on/off switch, unplug the modem instead of turning it off.

    Figure depicting checkbox Find and remove spyware. Spyware can run silently in the background whenever your computer is operating, draining memory and processing resources and significantly slowing your system's performance.

If filters are missing, you may experience reduced DSL speeds as well as static or hissing on the telephone line.     See Also: Intermittent connection issues
