I have Home920 plan at home and noticed that my upload speed is around 250-300 when I do a speed test.

So I plugged my windows laptop into power, used a cable did a test using Speedtest App with same results. download around 920 upload 280

So I tried another windows computer - similar results.

I tried different speed test servers

I asked my mate to do at test at his place and got similar issues with upload on his and my pc.

He is on a different Isp but on similar plan 1000down 500 up

Tried with m2 Mac book at his place- upload is perfect.

Took his Mac book home upload is perfect - 450mbit.

So I tried Speed test at different location on different windows computers and upload speed everywhere was no more than 300mbit.

If you have a chorus fiber with speed 1000/500

Can you do a speed test at your windows computer and give me your result link it would be great

This seems like the issue covered on here many many times previously. Update your NIC drivers from the manufacturer, not from Windows update.

Have you checked for the latest NIC drivers?

Maybe try a Live Linux distro to see if that makes your NICs work and to point the finger at the Windows install.

I did download directly from intel website and manually update.

I have stuff downloading from the seedbox so that will be why the download is low.

Quite a few things with Windows and the bloatware that comes with HPs, Dells etc. that can "tune" your network performance e.g. from a little googling https://community.intel.com/t5/Wireless/How-to-permanently-disable-Killer-Prioritization-Engine/m-p/1467885.

Try a Linux Live CD/USB to see if it is Windows or something loaded on Windows.

The fact that the Mac was OK points to something in or installed on Windows interfering with your upload.

Hey there. Saw this and thought I'd share (although not a driver issue in my case) Yes, I'm seeing a massive drop in my upload speed.

- I'm on a Orcon Gig fibre plan (1000/500) Been on the plan for the last 4 years with zero issues.

- Around a week ago, my upload speed tanked from an average of >=500Mbps to now I'm lucky to get >150Mbps. Download speeds remain at >900Mbps.

- Get the same results running tests using both Windows 11th Gen CPU PC and M4 Macbook using both Linetest & Speedtest local installs and their CLI's.

- No driver issues as NIC gets near full 1Gbps for downloads, only slow upload speed (and same results seen across both Windows and MacOS).

- Both devices directly connected via CAT 6 ethernet to the standard Orcon router (NetComm NF18ACV)

- Called up Orcon Tech support, did the reset, reboot routine but still the same result. Ran and submitted the Linetest Speed Diagnostics diag tool and waiting on their analysis

Test results below and a few screenshots hopefully attach...

kiwitechman:[snip] No driver issues as NIC gets near full 1Gbps for downloads,

I'm not saying yours is a driver issue, particularly if you have tested across multiple OS's, but that logic is completely inaccurate. Sending data is different to receiving, particularly as it is the sender that is (generally) determining TCP packet and window sizes.

You're also on a different ISP to the OP and unlikely related to the OP's issue. Probably better to start a new thread if you are wanting help.

@kiwitechman you would be better off looking at this thread - same ISP and similar symptoms. https://www.geekzone.co.nz/forums.asp?forumid=81&topicid=318482

I am on wifi and windows 7 so my download is a bit limited but upload seems good.

The main issue will be your tcp tuning. I am pretty sure at some point i ran that the speedguide.net tcp optimizer app for windows and adjusted the registry settings accordingly.

In summary, the tcp protocol isnt ramping up fast enough for a high speed connection before the test ends.
By setting it to be more aggressive then it can ramp up quickly, at the cost of introducing jitter and bufferbloat which is something gamers probably dont want.

Different operating systems handle it differently.

If you were to perform two uploads at the same time, or from different computers at the same time, you would be able to saturate your upload capacity, provided those destinations were close enough for your tcp windowing to allow a ramp up to a 250mbit speed each.
