Hey,

Router: linksys wrt160n as router 300mbps max
Wireless card is the TP-Link TL-WN722N USB 2.0 150mbps max
NAS Station: Synology with a 1 TB hd in it

I want to transfer a large .mkv like 9 gigabytes from my pc to my nas station trough wireless
It seem that the maximum speed is like 2.7mb per second. Although my wireless usb adapter can get 150mbps maximum, thats like effective 12 mb per second.
How is it possible i don't get the maximum transfer speed? I already turned of my antivirus on my pc, still no increas

Thanks in advance
