I've just got 100mb internet in the flat but was only getting speeds of 70mb. As it turns out (an engineer had to call) my ethernet cable (supposedly 5e) just wasn't up to scratch. It's a 50m cable running into the desktop in the office. I was under the impression that cat5e was capable enough for gigabit speeds so it's probably just a rubbish cable.
I saw this cable here and was wondering if anyone knows whether it would be good enough for my needs.
