Whenever my girlfriend turns on her mac the ping on my PC goes through the roof.

I'm attached to router with an ethernet cable and she joins wireless but as soon as she does, my ping jumps from a steady 20ms to over 500ms.

If she disables internet or turns off computer then my ping drops back to normal pretty quickly.

We are the only two computers on the network.

Does anyone know why this could be as I have no idea when it comes to macs

Thanks

Hi Crater34:

Did you find a solution for this? I have an identical issue: when my wife connects to our network, my connection basically fails. Ping to google.com drops from ~50ms to ~350ms. As soon as she disconnects, all is fine.
