So I finally got my 100mbit/s connection since last week and boy, does it feel like overkill. :D Now I download huge amount of gb's in mere minutes when it took hours before. Like, updating Star Citizen took a full night, getting latest ArmA3 dev branch updates took at least half an hour, etc... I start Steam now, do something else and when I am back 5 minutes later, every game update has been finished. Feels really weird to me, heh.
Now I get why there is this "turn your unused capacity into a free internet hot spot" service thing in the contract ... my connection is in idle mode most of the time now, as everything is done so quick. Just sucks for everyone around that the router range is extremely short. :>
