After all kind of reset's and nothing seem work, any idea? They ask me wait 24h but is there other any chance to be fixed

Hi @Bob Lazarides, welcome to our forum! 0.42 is quite slow for an upload speed!
Has the situation improved since?

If not, could you elaborate how you're measuring the speed and how your devices are connected?​​​​​

Hi, I'm experiencing something similar. 

0.5 or 0.3 sometimes upload speed which is ridiculous. Did you got it fixed somehow?

Zelfde probleem 0.1 mbps upload al een paar dagen dit probleem. https://kpn-itns.speedtestcustom.com/result/7985f480-f309-11ec-8196-65e79dd7f3bd

Out of nowhere today, I see 932 Mbps down and 936 Mbps up.
What was the problem, I guess well never know.

Happy to see that your speed is back where it belongs!
