Hi, the upload rate of my Intel Centrino Wireless-N 100 BGN (REV=0x6C) with firmware version 39.31.5.1 build 32895 is about ten times faster on Windows 7 (~ 4500 KB/s) than on Linux (~ 500 KB/s) when uploading files to my NAS device. I'm running Kubuntu 13.10 with kernel 3.12.0-031200-generic. What could be the reason for this problem?
