If 5 volts from the PC arrives at the router then you have a very broken 
PC.

What PG said was that as soon as the 5 Volt standby rail from the power 
supply is there (when the power supply is plugged into the mains) the 
network card becomes active and the link light on the router (and 
network card) will light. A modern PC is far from 'off' when it's been 
shut down. To be honest, your best bet is to bin the dodgy splitter and 
spend a tenner on a small network switch to hang off the back of the 
router.
