Hey everyone. I've been having such a tough problem for a while now. My pc has really really low upload speeds. Ookla's Speedtest either doesn't upload altogether, or shows 0.03 Mbps. This has caused me to be unable to upload my crappy musical endeavors on SoundCloud (probably for the better) but also has Discord showing my voice connection in the red. I also can't send images on Whatsapp Web, though text manages to go through. This textpost will no doubt go through as as well. I think it's just that I have really really low upload, not that it's inexistent.
I've tried;
repairing my ethernet drivers
speed testing in safe mode
speed test on my phone via wifi (showed proper up speeds)
changing my DNS settings from Google DNS back to default
ipconfig /flushdns etc in CMD
And probably some more stuff I'm forgetting. I suspect that my ethernet cable may be faulty, if one of the 8 wires in it isn't properly connected? We had to re-attach the tip of it after routing it through the wall. We've done this before though, so I dunno if the cable's to blame either. I'm also going to try a USB wireless adaptor, for diagnostic purposes as I'd rather not actually use a wireless connection.
Thank you all in advance!
