So my house finally got fibre to the house . Gone from having a 30mb connection to a 1gb connection. My question is if I have a 1gb broadband plan should I be getting fairly close the 1gb speed fairly consistent? So maybe 900mb consistently? So when I first got it for the first few days I was hitting between 800-980mb consistently. But now I only get 500-600 at best throughout the day. I know the old "copper"cable was “up to” 100mb. And you got whatever you got. But with fibre I assumed you would always get pretty close to the advertised speed or am I wrong? Thinking of changing to 500mb as it’s cheaper and I’m technically only getting 500mb now anyway. Tested speeds are wired with cat 6 cable on a laptop.
When you were getting 800-980 speeds. How many devices was connected? How many now? Have you added any new plugins to your browser? Did you test on different browsers? Try different speed test sites? Try a live boot of a Linux flavor to weed out anything that might be Windows related?
You can live boot distros like Mint, and Ubuntu both very user friendly Linux. Test speed that way. If your internet speed is back up, your speed decrease is on Windows side.
