Windows 10 is not using full internet speed

Hey,

I've recently upgraded to a 500 Mbit/s contract. I've noticed that I don't have access to the full extend of that speed under Windows 10. This is definitely not a hardware sided problem. I have full internet speed on a Mac OS device and also booted my computer with a linux usb where I have the full 500 Mbit/s (slightly more than that actually). So this problem must be caused by something on the OS level or smth building up on that. The speed I have access to is somewhat around 370 Mbit/s. Weirdly I have the exact same speed on my PS4 which is known for throttling down the internet speed.

Some useful information hopefully:
- Windows Version: Build 18362.720
- The PC is connected to the router directly with a LAN cable
- Full internet speed on a Mac OS device
- Also full speed when I boot the exact same PC with Linux
- The only antivirus I got is Malwarebytes and probably Windows Defender
- The adapter and router settings are both set to 1 Gbit/s
- Network adapter: Intel(R) Ethernet Connection (2) I219-V

I'd be grateful if anyone knows what could be causing that or what I can do for troubleshooting this.

If you're using Ethernet, have you checked the Ethernet cable to make sure it's CAT5E, if you're using the old CAT5, then the max speed the LAN will set to is 100Mb/s, and you'll probably only get around 10-15MBs (yes I did say bytes not bits), whereas CAT5E, can handle speeds up to 1 gigabit, I had the same problem and wondered why my LAN was running at 100Mb/s, whereas all my devices are 1 gigabit, after searching the net it was found that my Ethernet cables where old CAT5, so I changed them all to CAT5E, and now my network card shows 1 gigabit and not 100 megabit.

Also, you will never get the full advertised speed unless you're using fiber cable all the way, I have 500Mb/s downloads and 50Mb/s upload, but I never get the full 500Mb/ I always get around 92.02Mb/s download and 10.75Mb/s upload, so, unless the entire world uses fiber optics, you'll never get the full 500Mb/s, also signals will degrade the longer they travel.

Did you try a speed test at Speedtest by Ookla - The Global Broadband Speed Test this will tell you what your actual speed it.

Of coarse you won't get full speed QoS stops it https://learn.microsoft.com/en-us/po...sserver2022-ps

My NIC don't support QoS, as this powershell command is supposed to return all adapters that support QoS, but in my case returns null:-

PS C:\> Get-AdapterQoS -name "*"

So that would mean I should get the full speed, but I don't simply because of other factors, ethernet cable, should be CAT5E, not CAT5, and the wiring outside the house going to my ISP, as well as other wiring from my ISP to other locations also contribute to slower speeds.

Actually those speeds you are receiving are normal and to be expected!

You're not going to hit 1000Mbps in a speed test on a gigabit connection.

Now unless of-course your speed is indeed 1200Mbps. Check by logging into your router settings! Is your connection sync speed 1200Mbps? If so then your Ethernet port is the limitation as you'll need to update network adapter to faster speed to achieve the full speed.

Most people on a gigabit connection get around 920-960Mbps. I haven't yet upgraded to Full Fibre myself though it is available here in my building.

The Cat5E cable needs to be upgraded as it is limited to only 1000Mbps. You need Cat6 cable or higher to achieve closer to your 1200Mbps connection. So that 200Mbps is basically a limitation by your network card of your motherboard and your Cat5E cable.

It appears that your service is also asymmetric rather than symmetric hence, that's why you are not receiving gigabit upload speeds. Bit like the Openreach FTTP service we have here in the UK that is limited to 220Mbps due to GPON limitation.

Though my Community Fibre that's available here in London does symmetric gigabit speeds as it supports XGS-PON.

I'm supposed to have an advertised speed of 500/50 Mb/s, but here's the kicker, speedtest.net always find the testing server with the highest ping response, which might as well be next door, and uses that, obviously it's going to show a high speed, a real true speed test is using a server outside the source country, such as Russia, China , or even Australia, so I use myspeedmeter.net to test to Australia, and even though my PC has a gigabit NIC, and all devices on my LAN are gigabit, and I'm using CAT5E, and my ISP speed is supposed to be 500/50, but to Australia, I'm only getting 5.7/9.7 Mb/s and London UK, shows as 2.2/10.9 so distance and equipment used between source and destination affect speed.

My ISP doesn't use fiber cable in my area, even though it is available, if I wanted fiber they would need to lay the cables underground, and my monthly cost would shoot to nearly $400/m, and that would just for internet, and that is where corporations are greedy, they know there's no other service in town, so if you want internet then you pay what they tell you, and there's absolutely nothing you can do about it, but in the UK, at least there's organizations that can step in and say "woah there, you're charging what? No you aint", but here in the US? You pay what they want or you don't get service.

You misunderstood the QOS you can disbale i in the registery by default it takes 20% of bandwidth Disable QoS Windows 10 - TechnoWikis.com

Only available in Windows 10 Ent, and Pro, not Home, as Home edition doesn't have group policies.

You really want the federal government to take over all Internet in the United States? No thanks. If you want to live in Socialist country there are plenty to choose from.

That's just it, the UK government isn't telling people HOW to use the internet or even controlling where you go and what you see (Unlike China or North Korea), they set up those organizations such as 'Oftel', to regulate what those companies do to it's users, and to help those users to not get over charged, and also to allow competition. Also those organizations may have been set up by the government but they are under civil service control.

In the US, there is NO such organization and if there was, it doesn't mean the US government is "controlling" the internet, it just means that ISP's would be regulated in how they treat their customers, and would allow other competitors to thrive without being force out by those greedy corporations, that take over and monopolize the industry, also those companies won't be allowed to charge whatever they liked. I would rather live in a socialistic country, than a corporate country, the latter being what this US is slowly becoming, but, nuff said about politics, as we are drifting off the OP subject.
