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?

Some questions which will greatly help in getting this resolved:

How are you connecting to the NAS?  Samba/Cifs?  NFS?  FTP?

A Samba/CIFS connection.

How are you measuring your bandwidth?

I use bandwidth monitors.

Check /etc/modprobe.d/* for a line that has something like:

iwlwifi 11n_disable=1

I haven't found a line like this in any of these files in /etc/modprobe.d/

A lot of distributions have that on by default as there have been issues
with the iwlwifi driver using 802.11n.

Are you connecting to an open or wpa1+tkip access point?  Try using
wpa2+ccmp instead.  This is required for 802.11n to work.  Windows may
not be enforcing that portion of the standard.

I already use WPA2.
