In properties there are only 3 modes:

1. b 

2. g

3 b/g

Hi:

I don't know of any wifi adapter that has a N mode setting.

All of mine have the same settings as yours does.

The max connection speed of that model wifi card is 72 MBPS with an excellent signal.

That model can only connect on the 2.4 GHz wifi band.  It is not a dual band wifi card.

You can check the connection speed as follows...

Go to the Windows control panel>Network and Internet>Network and Sharing Center.

In the View your active networks section, on the right side of that section click on your wifi connection.

It will show the connection speed there.

N is anything more than 54 MBPS.
