How to query a card for its capabilities
 

I am trying to programmatically obtain the details about a wireless card I have installed. When the kernel modules are loaded, I see the information. It apears that the kernel drivers, wlan and madwifi, query the system for available devices, then displays some information about them.

What I am trying to obtain is the supported speeds, and IEEE modes. For example, does the card do 802.11a and/or b and/or g. If so what speeds does it support. I have two cards, a DWL-520 (802.11b) using the linux-wlan-ng/hostap stuff. And a DWL-AG650 (802.11a,b.g) card using the madwifi driver. Both work just fine. Linux kernel 2.6.6.

What I want is to be able to determine a cards capabilites. The app that I am writng is a Java app.

This command will output the information you want:
