Why is My PC's Upload Speed So Much Lower Than Other Devices?

I've got a pretty decent internet connection with 170 Mbps download and 11 Mbps upload, especially because it's 5G, so I expected lower upload speeds. However, on my PC, I'm only getting around 7 Mbps upload speed. I don't have any VPNs running, and nothing in the background seems to be using more than 1 Mbps collectively. My setup is pretty solid too, with a 5090, 64 GB of RAM, a 9950x3D, and I'm using Wi-Fi 7 along with a 5 Gbps Ethernet connection. Any ideas why this is happening?

It sounds like your issue could be due to limitations on the service itself. Remember, 5G is a shared medium, which means if there are a lot of users online, your speeds can drop significantly. Are you noticing this speed drop specifically on your PC, or is it consistent across all devices?

TechieTornado92: On my phone and other devices, it's consistently at 11 Mbps, so itโ€™s only the PC thatโ€™s having this issue.

How are you testing your upload speed? Are you using any specific tools or websites for the speed tests?

TechieTornado92: Iโ€™m using Ookla's speed test, and Iโ€™ve also tried Googleโ€™s speed test and a couple of others just to verify. They all give me the same result.
