I was trying to activate network sharing on my computer and I had this error message from the terminal

Your wireless card or driver does not support Access Point mode. 

My wireless card info is as follows

description: Wireless interface
   product: Centrino Advanced-N 6200
   vendor: Intel Corporation
   physical id: 0
   bus info: pci@0000:03:00.0
   logical name: wlan0
   version: 35
   serial: 00:27:10:80:db:30
   width: 64 bits

I am not a comp guru but can follow instructions very well, please help.

Answered very nicely here already,

To use your network card as wifi hotspot, it must support AP mode & master mode.

To check master-mode run:

sudo iwconfig wlan0 mode master. 

If you dont get a error then it supports master-mode

To check AP run following command:

sudo apt-get install iw

Then run:

iw list

If there is 'AP' in the list of "Supported interface modes" your device will support the Access Point mode with hostapd.

But as you explained above, that it doesn't support AP mode, The wifi hotspot wont work as explained in the blog.

Unlike windows, linux-kernel doesn't provide same features for every wireless cards.So for a particular wifi-card, windows driver may support AP , but linux-driver may not.

One option is to purchase a wireless card which supports AP modes.
