We've just swapped isp and have set our network up exactly as it was. We are having really bad connection issues on our network to outside sites. Running Ping Tester we are getting about 13% loss when pinging google for ten minutes.
The weird thing is that when just one person is in the office it seems fine. It's only when others start using it that it starts dropping out all over the place. I know really nothing about network setup and realise that I'm out of my depth. Can anyone shed any light on why this might be happening (I bet it could be a million things) and how to solve it.
We are using a hardware fire wall (ServGate EdgeForce).
