When copying a file from my laptop to my PC or vice-versa on my wireless G network I only use about 20% of the available bandwidth (according to Windows Performance). Both are connected at 54mbps though and the signal strength is 'full' on both the laptop and the PC.
I know that, in practice, nobody gets the full 54mbps from their network but as I'm working to setup a home streaming-media solution for multiple PCs, getting that 20% up to 40% or 50% will make a world of difference.
How do I tell which device is imposing the 20% or so limit - is it my PC's wireless card that is the 'slow one' or is it my laptop? Is there anyway to test the speed of just one device at a time with some sort of networking tool?
