    How to tell if wireless N is being used?

    Morning,
    Laptop- Toshiba Satellite A505D-S6958
    OS- Ubuntu 10.04, 32bit
    Wireless- Realtek rtl8192E 802.11bg+n

    My question is:
    If my laptop is connected to a wireless network that supports "g and n", how can I tell if the laptop is making use of the faster "n" protocol and not just the "g"?
    I remember in Windows that I had to change the setting on the NIC specifically to use n...

    Thanks,
    Tony ...

    iwconfig will tell you the bit rate. 54 Mbps is wireless G speeds, anything above that should be wireless N, but theoretically it should be around 300 Mbps. I've never gotten above 108 because my router sucks with mixed mode with other Wireless G speed devices on my network, therefore reducing a potential 130-150 Mbps realistic speeds to around 108 Mbps.

    If there's any trouble, it's likely to do with the driver you're using.

    The router will run at the lowest speed, so if you have G devices, then it would run at the G speed. Once all of the devices on the network run N, then you should see the N speeds.
