So here's the thing. I've been fixing Pc problems (viruses, missing drivers, broken settings etc.) for a long time now and this is the first time I've seen this happen.
I have my main PC connected to a modem for internet access (max download 2.2MB/s, max upload 0.120MB/s) and it has always worked great. Recently I bough a laptop and here's the strangest thing, whenever it's turned on and it's being recognized by the modem, internet speed goes down hard. From 2MB bouncing to more or less 80KB/s or non at all. Whenever I turn it off or unplug the lan cable everything goes back to normal on my pc, but it's the opposite when it's on and plugged whether my Pc is plugged or not.
Could it be that the ethernet card is damaged? In this case I don't see how this can interfere with my own Pc's internet access. This is absurd.
