Consider the following network: Two desktop PCs with wired connections to a gigabit switch, and a laptop with a wireless-G connection to a router hooked into the aforementioned switch. If I were to get on one of the desktops and copy a file from a shared drive on the other desktop, it would be traveling over the 1,000 Mbps wired connection.
So what happens if I'm using the laptop, go into Windows Explorer and then do the same operation, copying a file from a share drive on one desktop over to the other desktop?
Are the computers smart enough to know where the file is coming from and going to and then take the fastest route between them? Or since the request originated on the laptop will it transfer the file to the router, the to the laptop via wireless, then back to the router, then along to the other desktop?
