What is steam download speed drops to 0?

When steam download speed drops to 0, it means that the download process has been interrupted or has encountered some problem. This may occur due to several reasons, such as slow internet connection, server issues on steam's end, firewall or antivirus software blocking the download, or even issues with the router or modem.

To fix this issue, several things can be done. Firstly, check your internet connection and ensure that it is stable and fast. Secondly, check the steam server status and make sure that they are not down or facing any issues.

If the above solutions do not work, try temporarily disabling the firewall or antivirus software on your computer and check if the download resumes. Additionally, restarting the router or modem, or even rebooting the computer may help in resetting the connection and resolving the download issue.
