Is my computer 802.11g or n?

[graemesangels]

Shortly after I purchased my macbook I paid for the upgrade to 802.11n. My router is now saying that I am connected as an 802.11g device. How can I tell if my computer is n enabled or not. I haven't been able to find the info on my computer.

Thanks.

Click on the airport menu bar icon while holding the "option" key on your keyboard. If your transmission rate is over 54 Mbps, you're connected at N speeds.

I use Network Utility. I'm connected at a lovely 130 Mbits right now.

Thanks,

I was connected at 54 Mbps, I guess I accidentally deleted the upgrade. I just redownloaded it and am now an n user according to my router and network utility has me listed at 130 Mbps.
