Very low speed when copied from the hard disk on pc

My router: WL500gp v2 and use it only for torrents .. set of tutorials of wengi.
The problem: speed of copying is very slow 5MB/sec hard drive connected to PC. Using windows 7 x64 and Ext2Fsd.
Only when I want to move it downloaded transmision speed is 5MB/sec.:eek:
