Question Upload speed is slow on my PC but not my phone on home wifi?

[alexbarrett414]

Recently I've been experiencing really slow upload speeds, around .7 to 1Mbps (Megabits, not bytes) on my computer. I thought it could be a problem with my modem until I tried a speed test on my phone (turning off Wifi assist so that doesn't interfere with it). Comparing the speeds I got on my PC to my phone, it was a significant difference. My phone had a 13Mbps up speed while my PC was still insanely low. I installed a new update for Windows 10 that's been sitting in my task bar hoping that would fix it, made sure nothing on my PC was using network speed, and even turned off the bluetooth adapter, but the problem still persists.

Note: My download speed is fine, it's only my upload

I don't know if this will help, but here are my specs:
Ryzen 3600x 4.2ghz @1.525v
Gigabyte GTX 1060 6gb Windforce OC
Ripjaw DDR4 16gb 2666mhz @1.3v (I think?)
**I also have a WiFi adapter in one of my USB 2.0 ports that I've been using for about 2 years now and this problem has only been happening recently. I forgot the brand but it's some Chinese made model

What are the ISP specs on the internet connection you have paid for ?
It may be the ISP that has an issue with his local hardware.
