Fast internet, but slow download speeds only on my PC

[stephanfs]

I have a weird problem on my internet connection since March and I don't know how to fix this.

I have a 100 MBs fiber wired internet connection, but my download speeds usually vary between 250kbps and 1mb/s. It usually reached the max speed on every other website (like 10mb/s), but not anymore. However, for some reason, it reaches the max speed if I download something from Steam, Uplay and Google Drive.

And before anyone says that it's the ISP, it's not: I've checked my brother's laptop via wired connection and the download speed there is normal and it reaches max speed on everything, unlike my PC. Dunno about wireless since my PC don't have Wifi.

I've tried this, but nothing worked so far:
- Bought and installed another NIC
- Ipconfig renew and release
- Updated the driver
- Changed the IPv4 to Google's IP
- Replaced the ethernet cable
- Tried other browsers

What else should I do? Here's my PC specs:

CPU: i3 7100 3.9GHz
GPU: EVGA GTX 1050
HD: Seagate 1TB
Network: Realtek PCIe GBE Family Controller
OS: Windows 10 64 bit 1803
RAM: 8GB

Sorry for the double post, but I have an update.

I booted Ubuntu on my USB to test if it's a hardware problem. To my surprise, the download speed on Ubuntu is more faster there than on my Windows 10. It's probably a software problem, but my problem right now is finding the culprit since nothing is eating my network.

Hi Stephan,

So glad I am not the only one encountering this.
I was wondering why internet was slow on one of my windows PC's and thought my internet was slow.

Not the case at all.
Android device can stream 1080p 60fps video just fine, no buffer, no lag.
Switch to a windows laptop, can't play 1080p.

Empirical tests using Netflix's fast.com showed the following:

Android 8.0 Oreo: 30Mbps
HP Windows Laptop: 2.1Mbps
Lenovo Windows Tablet: ~500Kbps
Custom Built Windows Desktop: 3Mbps
Linux Elementary OS: 30Mbps

To determine whether it was a NIC issue in the Desktop, I USB tethered my phone, still was getting 3Mbps, which is weird as my phone itself is able to connect just fine with fast speeds, but suddenly when pushing the internet through, its slow as.

So I decided to boot Ubuntu on my USB on the Custom Build Desktop using the same NIC, and lo and behold, I start getting 30Mbps.

What on earth... Thought I was going insane, until I found your post!

I did wipe windows and leave Ubuntu on my desktop, as its a far superior experience, but I still want to solve it on my other Windows devices....

If you have any further information, or potential fixes, love to hear them!

Looks like you and I are on the same boat.

I've tried to find the problem for months, but no luck so far. I still wonder if this is some kind of Windows 10 bug that hasn't been fixed by Microsoft or an unrelated problem.

One of the suggested things I found for semi-related, but not entirely fits our issue today, is to find out the make and model of your wireless chipset and/or lan chipset, then go onto the manufacturer's website, and download specific drivers.

Apparently windows does some assumptions when downloading drivers, so might not actually be the specific version which is required. Where Linux is far superior, in that it uses the right driver for the device.

What frustrates me, is this shouldn't even be happening in the first place. And its not like its a hardware issue with our computers, considering its over different devices, with different hardware configurations.
