I'm trying to move a 4Go file from a pc running under windows XP to another runing windows Vista / 7, but the copy speed never go beyond 1Mo/sec.
Both computers were connected to a router via wifi, then I connected them directly with a network cable and it shows that the speed is 1Gbit/sec like follows, but nothing changed at all.

I disabled the firewall on both the PC's but nothing so far!
Are there any utilities or some hacking tricks to make things speed up?
