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.
Fiber can certainly suffer from the exact same issues as copper - a neighborhood or group of homes or town or whatever connects to the Internet over a single piece of cable or logical connection, or a single piece of equipment, and those can become congested.
In theory, that could limit your maximum available bandwidth by limiting everyone’s bandwidth.
But with Fiber, the infrastructure is newer and generally installed with future capacity in mind. Also, fiber is cheap and labour is expensive, so the fiber from your home may continue for some distance before it reaches the first piece of powered equipment, which helps make a physical fiber network more economical, and more redundant.
