Hi All,

 

I have an issue with the internet upload speed on our home desktop PC.  Here are some details:

 

  • Internet plan is 300/100Mbps fibre with Vodafone
  • Modem is Vodafone HG659
  • Based in Wellington
  • PC concerned is connected via Ethernet cable
  • Speed test app reports normal download speed of 325Mbps but only 0.6Mbps upload speed
  • If connecting via WiFi both download and upload speed are normal (download 190Mbps, upload 100Mbps)
  • Other PCs (laptops) connected via the same Ethernet cable have normal 300/100Mbps speed

 

 

So, the issue appears to be specific to one PC and only for the upload speed and only on the Ethernet connection.

 

Also, the issue only started happening since last Saturday (4th Feb). Prior to then the upload speed was fine. Not aware that any updates have been applied to the PC in that time.

 

I have restarted the PC, the modem and the ONT with no improvement. Windows update reports drivers are up-to-date. I have also run the Windows troubleshooter which reports no issue detected.

 

My technical knowledge has reached its limit so any advice on what may be causing the problem and any suggestions to resolve the issue would be much appreciated.

try using the browser or CLI to do the speedtest instead of the app, also try something like fast.com to rule out the speedtest app as the culprite

 

also try uploading a large file to something like google drive/dropbox etc to see if it is actually slow or just the app showing its show.

Thanks for the ideas.

 

I initially noticed the issue while uploading a large (6MB) file to attach to an email in Gmail.

 

I had already run speed tests in the browser using both the Vodafone and Chorus speed tests.

 

I've now tried them again and also tried fast.com as you’ve suggested and they are all reporting slow upload speed (0.8Mbps).

 

I’m not sure what you mean when referring to CLI.

 

Interestingly, I just tried loading the 6MB file to Google Drive and it uploaded in about 5 seconds. I then tried attaching it to a Gmail email and it took 7 minutes to attach.

CLI = command line interface





Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

CLI is command line interface, but your other tests seem to indicate there is and issue somewhere. have your tried a different network cable between the PC and what ever its connected to?

I once had an issue like this after Windows Update had applied a network driver update. Reinstalling the manufacturers recommended driver resolved it.

I tried a different cable but this did not make any difference.

 

I did however find a driver update which I installed. After rebooting, the upload speed returned to 100Mbps. Unfortunately about 2 hours later the speed has dropped back to under 1Mbps.

 

I'm still on Windows 10 so am wondering if it's time to do the Windows 11 upgrade and hope this resolves whatever is going on?
