If you're experiencing a 0 Mbps upload speed, it means that your internet connection is not providing the necessary bandwidth for uploads. This can be caused by several factors, including:
-Your internet service provider (ISP) may not be providing the promised speeds. This is particularly common in rural areas where ISPs often oversell their capabilities.
-There may be an issue with your modem or router. If you're using an outdated model, it may not be able to handle the speeds your ISP is providing.
-You may have too many devices connected to your network and they are bogging down the available bandwidth. Try disconnecting some devices and see if that improves your upload speed.
-A virus or other malware on your computer could be causing the problem. Run a security scan to see if that's the case and remove any offending programs.
