New built computers internet is really slow

[Brunkeen]

So I just finished building my first computer and it booted on the first try. When i tried connecting to the internet via an Ethernet cable it didn't recognize it. Luckily I had an wireless netwok card lying around so I put that in my new computer and it connected to the internet, however i only got about 1mb/s up and down. My phone, connected to the same wi-fi network, at the same location in the house, gets about 70-80 mb/s. 
I then tried downloading the motherboard LAN drivers and suddenly the Ethernet cable was recognized. I disconnected from the wi-fi network and ran a speed test and had the roughly the same results as before. 1mb/s up and down. I tried connecting my PS4 with the same Ethernet cable that I used for my computer. I got 190mb/s down and 210mb/s up. Every other electronic device that is running on the same network works fine.

I have 250/250 fiber internet

I downloaded all the latest drivers and bios for my mobo and GPU

My computer: 
Intel core i5 6600k
MSI Z170 PRO GAMING CARBON
8GB DDR4 HyperX Memory
AMD Sapphire R9 390 Nitro backplate 8GB
1tb Seagate hdd
500gb SSD Corsair Force 
Corsair h60 v2 liquid cooler

What OS are you running?

This is a stupid question but do you still have the wireless card installed? I have a pci ethernet card and when I tried to update the lan driver for my motherboard it screwed up the driver for my pci card. maybe this is a complication? also, maybe try updating the driver again after the wireless card is removed if it is still not working.

Can you do a lan speedtest? Transfer some files inside your home network and see if your pc can do more than 1 mbps.

So first of all i´m running Windows 10. 

 

I'll try to remove the wireless card and return later

 

Well the speed test went fine 498 mbps for my ssd and about 185 mbps for my hdd

Still no difference in network speeds after removing the wireless pci card and reinstalling the LAN drivers... What now?

[Lurick]

Do you have a file server or other device which can share a folder on the local network like another windows box? If so download either LAN Speed Test or AIDA64 and use that to speedtest between that PC and another on the network. I see you did some form of speedtest above but those numbers don't seem to make sense, was it a disk benchmark that you did?

[Brunkeen]

I did a disk benchmark and got my results from there...

I'll attach benchmarks for my hdd (C:) drive and my ssd (A:) drive

i don't have any file server or windows box. Nothing like that...
