There are ten main factors that can affect your internet speeds, and this infographic details them. The type of connection, either Wi-Fi or Ethernet affects your speed, as does the hardware you’re using. Spyware and an out of date router can really cause your internet to lag, especially if your router isn’t in a good location and the signal has to travel through obstacles. Your browser, as well as the host server if the speed issue is localized to one page, and network traffic can negatively influence speeds. The ISP is the most important factor when it comes to speed, and your OS plays a role as well.
