1. The age of your computer. Many older devices lack the memory to achieve the best download and upload speeds, even when the Internet connection and service is strong and robust..
2. Connection to the website/browser you’re using. The speeds you can achieve when downloading or uploading documents, files, or photos is affected by the distance from your computer to a website, as well as the path, speed and capacity of the website’s connection to your own network.
3. Website traffic. Popular websites may be the most difficult when it comes to achieving higher speeds. And, often times, the problem isn’t with your connection. Instead, it could be the result of an overloaded website. A classic example of this is when you’re trying to upload photos to a site that allows you to create albums or order prints online.
4. Viruses. If there are viruses or unnecessary software running in the background on your device, it can reduce processing power as well as the speed available for sending and receiving data across the Internet.
5. Software. When is the last time you updated your computer or phone’s operating system and other software? If you’re running an iOS on your iPhone or MacBook that’s three years old, for instance, you’re not going to achieve the highest speeds when downloading or uploading things.
