How to tell what Wireless Signal Tablet Uses?

I have an Asus TF101 Tranformer android tablet. How do I tell what wireless signal it uses? In the settings, About tablet, it just shows that the wi-fi version is V6.1.1.24 and the Android version is 4.0.3 - not very helpful.

There's a wireless router outside my office in the ceiling. My IT person says it's working, but I am not finding it. He asked what signal - a/b/g/n?

Suggestions?

Thanks
