Factors Affecting Internet Performance/Slow Internet

Slow Internet: Troubleshooting

Many factors can affect speed performance including the age of the device, existing software, and any viruses or malware. Follow the steps below to improve your internet performance.

Factors Affecting Internet Performance

Consider the following:

  • File-Sharing Programs: File-sharing programs like BitTorrent uses huge amounts of data, which can lead to slow connection speeds.
  • Viruses/Adware/Malware: To check your computer for harmful software, download Security Suite.
  • Firewalls: A firewall monitors all network traffic on your computer, so a strict firewall can lead to slow internet speeds. Try resetting your firewall to its default settings.
  • Power Outage: Check to see if you’re facing an outage.
  • System Memory (RAM): Close any programs not in use to increase your computer’s performance. You may also consider upgrading your computer’s RAM.

Take a Speed Test

Test your upload and download speeds.

Run Speed Test
  1. Make sure you’re using the latest version of your browser.
  2. Make sure to disconnect any devices not in use (i.e., iPad, mobile, etc.).
  3. Make sure your system meets the minimum requirements:
PC Minimum Requirements
Mac Minimum Requirements
  1. Wired Speed Test: It’s best to test your speed first using a wired device, such as a computer connected to the modem with a Cat 5e or higher Ethernet cable (It should be labeled on your cable.)


Note: If it’s not possible to test your speed with a wired connection, you can download an app to test your speed over wireless.
  1. Restart your computer or device.

Reboot Your Wireless Device

  1. Unplug the power cord or remove the battery from the wireless device that is experiencing slow connection issues.
  2. Allow at 30 seconds before reconnecting it.
  3. If you are using a wireless adapter, such as a USB adapter for Ethernet or WiFi, unplug the adapter, and allow at least 10 seconds before plugging it back in.
