How do I check if I am using a 2.4GHz or 5GHz internet connection?

I remember reading in thread that you can do this, but I cannot find it. So how do I check if I am using a 2.4GHz or 5GHz internet connection?

You don't use a 2.4GHz or 5GHz connection. You use Dial-UP, DSL, LAN or some kind of other internet provision.

2.4GHz refers to the 802.11 b and 802.11 g wireless LAN protocols, using 11 Mbit/s and 54 Mbit/s.

5GHz is used with the 802.11 n standard with a net bit rate 600 Mbit/s.

It depends what kind of router is used to connect to the internet and if you have an 802.11 n-enabled airport card.

Most ISPs don't offer speeds of more than 54 Mbit/s or even 22 Mbit/s (the practical throughput of 802.11 g (2.4 GHz).


But sorry if can't help you finding out what protocol you use.

Hold down the Option key while you click the wireless icon in the upper right hand corner of your screen. Right next to the channel number will be what you're asking.
