I am going to be buying a router that will share an internet connection between three computers. Before I buy, I would like to which of these scenarios apply, as I am a bit puzzled :
1. The connection speed is always 1/3 of what it usually is, even if the computers are off.
2. The connection speed is only 1/3 of what it usually is if all 3 computers are on (but not nesseccarily using the internet).
3. The connection speed is only 1/3 of what it usually is if all 3 computers are viewing web pages etc.
4. The connection speed is always at the full speed at all times no matter what, between all 3 computers.
5. Something else.
Basically, I would like to know how the connection speed changes. What does it depend on etc?
I hope that made sense - I just don't want if to be always 1/3 normal at ALL times.
