If you have a web interface of your router, you may look around the settings and there should be an option for that. –  Mehper C. Palavuzlar Mar 15 '10 at 8:26

I'll include a pic of mine for an example:

That will just tell you what type of networks your wireless card supports, not what it is currently connected to.

And there is a way to get G as high as 108MBps (on Netgear routers). –  Traveling Tech Guy Mar 14 '10 at 23:11
    
The problem with this is that Window's doesn't give a fig what the actual throughput is for a network. All it shows is whatever the wireless adapter's driver tells it to show. This is usually the current link rate. Why else would it so often list an 802.11n as 300 Mbps? As if ... –  irrational John Jun 25 '10 at 22:22
