Client: So can you ping my router?
Me: No sir I am unable to ping your router. Can you tell me what colour the status LED's are?
Client: I don't see any colours?
Me: Sir is it powered on?
Client: No we are doing some maintenance works, so we had to power everything off.
Me: Well in order for me to ping your router it needs to be powered on.
Client: Are you sure you can't ping my router?
Me: No sir I am unable to ping your router unless it's powered on.
Client: Oh... okay.
