Cannot get dot11radio configured

[jturpin011]

Hello, I am experiencing difficulty with a router entering into dot11radio0. It is an 881 w ISR with a Cisco IOS version 15.1. when I enter this command I get an invalid syntax message. I am new at configuring wireless, and am not sure of what I am doing. All videos I have watched, manuals I have read, show this configuration below.

conf t

int dot11radio0

This is as far as I get, and get the error message. Am I missing a step, or doing something wrong?
