Check your internet speed. Your internet speed might be slower than the expected speed listed on your plan. A slower speed can be caused by a variety of things (router placement, too many users on the network, ISP issues). This is a good first thing to check!
- Go to a website like https://www.speedtest.net/ to check your internet speed .
If you're trying to upload multiple files, or there are multiple users on your network, uploads may take longer than normal. Try uploading single files at low-traffic times for faster speeds.
Ethernet connections (also called wired connections) are faster and more reliable than using Wi-Fi. This can significantly increase your internet connection speeds .
If you've noticed that your upload speed is too slow even though it's meeting your plan's specifications, it might be time to upgrade your internet. ISPs often have multiple plans rated at different speeds. ^{[4]

- Place your router on a table so that it's near the level of your wireless devices.
- Make sure your router is in a central location for the most even coverage.
- Try to set your router up near the device you use to upload, such as your desktop computer.
- Orient your router's antennas perpendicular to the ground. Wireless signals project out the sides of the antenna, meaning they're most effective when pointing straight up. If your home has multiple floors, you can change the orientation for better coverage.
This can resolve minor issues with upload speeds and fix internet connection problems .
Make sure you update your router firmware to get the latest update for the best possible connection.
If your router is older, it might not have the capacity for higher upload speeds. Look for a router that's rated for the upload speeds you need.
