[SOLVED] Internet speed is slow on new computer

[Walf]

Disclaimer, not very tech savvy.

I've been having trouble with my computer's internet ever since I got it last August and figured it was just a problem with our provider but I decided to take a look on my brother's PC and he's getting 100Mbps of download whilst I get less than 10Mbps, which is dumb considering he's using a WiFi adapter and I'm using an Ethernet cable so I'm starting to think it might be a hardware problem.

My current specs are:
Motherboard: MSI B360M Xtreme (CPUSocket)
CPU: Intel Core i5 @ 2.90GHz
OS: Windows 10 Home 64-bit
RAM: Single stick of DDR4 8.00GB
The internet provider we use is Bell Canada and I'm currently connected the home hub 300.

Second computer specs are:
Motherboard: Dell Optiplex 390
CPU: Intel Core i5 2400 @3.10GHz
OS: Windows 10 Pro 64-bit
RAM: 2 sticks of DDR3 8.00GB
The WiFi adapter is a TP-link 300Mbps

We have around 2 PCs connected at almost all times, a laptop on half the time and around 4 phones if that helps in any way.

Any help would be appreciated, thing's been haunting me for months

Does your computer connect DIRECTLY (no wall plates, etc) to the home hub? Are you using a flat ethernet cable?

It's connected directly to the modem using a flat ethernet cable, same one I used to use on the second computer which I believe had around the same download and upload speed.
I should probably ask which on is which, I ended up making this one myself, and round cables look different from what I can understand.
Looks like this !

Start by replacing that flat cable with a certified cable. Flat cables have wires that are too small in diameter. Get a 100% copper 22-24 gauge cat5e cable and retest.
