Here are some steps you can take to troubleshoot slow download speeds:

1. Check your internet connection and determine the average download speed.
2. Check your device for any viruses or malware that could be slowing down the internet.
3. Restart your router and/or modem to try and improve connection speed.
4. Check the router for any restricted bandwidth settings that could affect download speed.
5. Connect directly to your modem instead of through a router device.
6. Check for electrical interference from other devices in your home.
7. Run bandwidth tests to check again after making any changes.
