I've been having trouble with a really slow upload on my computer lately. My main PC is like 1/5th to 1/15th as fast at sending data as my phone when it uses wifi. I looked at lots of websites and forums but couldn't figure out how to fix it, so here I am asking for help.

The website blocks me from posting pictures right now. My file size for uploads is tiny at .01, and my downloaded files are 300 megabytes big.

Usually, this just means your cable is fine and isn't a hardware problem. Most problems like this happen to both going down (downloading) and coming up (uploading). It's hard to know exactly what software is making it, sometimes. I'd first check for any programs that talk about speed limits or giving more favor to certain traffic. There are lots of these on motherboard and video card boxes along with other junk called bloatware. Any software like that, I remove. Even though it's probably not the case, I might try turning off the firewall just in case. Not sure what else I could try. Usually, I suggest trying a Linux USB drive image. This would let you prove it was something in the Windows installation causing it. That doesn't really help you find where, but anyway. What speeds do you get if you copy a file from that machine to another via your network? If those speeds are very slow, they'd be pretty obvious, but you can see them right there in the resource monitor window under the network tab. If this works well, it would mean something like the browser might be causing the problem.

I almost never connect to the internet through my Ethernet cable. Maybe the router settings are the issue, or maybe just blocking things in Windows. My firewalls are turned off, and since I don't run any antivirus, nothing is stopping anything from happening.

Is it possible that your phone is sending data over WiFi instead of the regular internet line? Sometimes phones use their own WiFi network if they are connected to the same router as your computer. This can happen because home internet often gives different speeds to you than to mobile, while mobile usually offers the same speed in both directions.

My computer connects to the Wi-Fi. I can get 100 megabytes per second for downloads and 16 megabytes per second when sending files. On the wired ethernet, my internet speeds are much faster: 300 megabytes per second down and less than a megabyte per second up. Even though my router says it's getting 300 megabytes down and only 20 megabytes up, I still get better speeds through the Wi-Fi connection on my phone compared to the direct ethernet line.
