Question Ethernet on PC has slower upload speed than Wi-Fi on phone

[etesravan]

I'm supposed to have a 100/100-plan and I get around 80mbps download speed with ethernet. My problem is that I only get around 1-3mbps upload speed. On my phone I can get around 10mbps upload speed.

I have tried to swap the cable with no luck.

Corsair TX850M, 850W PSU
Kingston A2000 1TB NVMe M.2 SSD

Live in Norway, but I've tried with another router and got same results.

Boot a linux live cd/usb and see if you get any different results.
