ELI5: Why are wifi upload speeds so much lower than download speeds?
gpt
It's probably not the wifi itself, but the Internet connection that the wifi base station uses to talk to the target machine. Many (most?) Internet connections are asymmetrical (larger download than upload) because for most users the download side is more heavily used than the upload side. You can get symmetric connections (I have one), but they may be hard to get in some areas, or more expensive, etc.

All most people upload is requests, form data, and maybe some small amounts of binary data, like pictures to an online album, etc. As such, the asymmetric connection is not really a problem for those users. If you're trying to run a web server out of your basement, then yes, the asymmetric connection is going to be an issue for you.
