The server was my machine, so my connection was kind of... perfect We wanted to check if there is any difference betwen WiFi and LAN cable by hosting two games on the same machine with different connections. It was everybody else lagging while trying to connect to a WiFi machine.
the result was simply devastating for WiFi... I did not expect such a difference myself...
I know that hosting a game is quite an extreme example, but if there was no difference between WiFi and cable, than why shouldn't a host with WiFi work?
30 meter cable? You are having quite a long distances to anywhere over there in New Zealand
The truth is there will never be a total agrement in this thread, because the number of variations of hardware/software/network providers/other factors makes it simply impossible...
But IMO there is one thing we could agree on: if you are on WiFi, and you experience some lagging from time to time, chcek it with the cable first, before blaming others. And if it solves the problem stay with the cable, even if it was from time to time only. Nothing more.
