How to Obtain SNR from AP??

[Rob Huffman]

Hi Jian,

As SNR is a relationship between the client machine and the AP you need to use a product like Netstumbler to find these values;

Here is some more info to help get you started;

Performing a Site Survey

From this doc;

If you are using a Cisco card here is where to download the ACU (you need CCO Login)

Hope this helps!

Hello,

from the Cisco 1242 web interface home page, select the "association" bar from the menu on the left hand side of the web page. Then click on the MAC address of the client you want SNR for.

good luck

If you have controller based APs in the client section open the client page and then do a link test to the client. This will give you RSSI, SNR, and packets sent and received. If you are running a high level CCX client you will also get data rates sent and received.
