I've got a Macbook pro, but I'm having an odd problem when I add an external monitor. The wireless speed slows significantly - from 300+K/s to 20K/s . It doesn't happen because I put the lid down, even with the lid up and both displays on the speed drops immediately I plug the monitor in.
I have the same problem regardless of whether the mains cable is plugged in or not.
I've also tried moving the macbook around the room whilst connected to the monitor but the download speed remains slow.
Without changing anything else, if I unplug the monitor the speed jumps right back up, then as soon as I plug it back in it drops again.
I can't think of any explanation for it, or where even to start looking.
Any ideas?
