Question: Reasons Why Highspeed Internet Can Become Sluggish

Answer: Slow internet connections happen for various reasons, even when you pay for a 'highspeed connection' like DSL or cable. Because the internet (and World Wide Web) is built on hundreds of different technologies trying to talk to each other, there are many places where data can slow down before its reaches your computer screen. Your ISP might be at fault, certainly, but there are many other factors to look at before assigning blame.

Some of these slow points are within your control, and can be quickly fixed with a little do-it-yourself effort.

Common reasons why highspeed internet connections perform more slowly than claimed:

  1. You might have poor hardware connecting your machine to the wall.
  2. Your modem-router may not be configured correctly.
  3. Perhaps you have dishonest people leeching your wireless connection from across the alley.
  4. Your web browser could have addons and plugin features that are consuming bandwidth.
  5. Your web browser might have security features enabled that are holding pages back while they perform safety scans prior to displaying the pages.
  6. Your network interface card (NIC) may be older and slower hardware.
  7. Your modem-router may not be the new 'gigabit speeds, and may instead be 10/100 megabit speeds.
  8. Your machine may have an open window or dialog box waiting for a user command, but you're unaware of this.
  9. You might have spyware/malware infecting your machine, and secretly using your internet bandwidth to send spam and distribute porn.
  1. If you are a torrent user, your uploads might be running the background and choking your bandwidth.
  2. A download may be occurring in the background, and you are unaware of it as it leeches your bandwidth.
  3. Your ISP (internet service provider) may be having issues with routing signals to you.
  4. DNS (domain name system) tables might be outdated, so signals are getting sent to the wrong addresses on your ISP network.
  1. Your browser memory cache is so full, your browser has to slow down to allow for its limited hard drive space.
  2. Radio or microwave devices in your home might be degrading your internet wireless signal.
  3. Your computer is more than 3 years old, and is not able to move electrons fast enough for modern web pages.
  4. You have unwittingly left dozens of windows open in the background, and they are clogging your computer CPU.
  5. A Windows or Mac dialog box is sitting open and unanswered in the computer background, stalling your computer CPU while it awaits your yes/no input.

These are just some of many possibilities. If you think that your internet connection is slow, we recommend you do two things:

  1. Do a speed test on your computer: speed testing or
  2. Perform a troubleshoot on your computer: Troubleshooting list for your internet connection.
