Big file transfers via WiFi... always a small fraction of the data rate that a wired 10/100/1000 connection can provide. Best rate you will see is transferring one big file, like 500MB. Better yet, two transfers concurrently, even on same (fast) PC; you'll see the sum of the two is markedly faster than one stream- due to overhead in all parts of the software and WiFi. Even better if two PCs, one big transfer each.
Wireless = convenience and mobility, not performance!
