|You should be able to connect to your router by typing 22.214.171.124 into your browser. |
from there you will be able to login to your router and change your security code, i am assuming you are talking about your wifi code? right?
if you are talking about your login details, then you will need to refer to the user manual, i think, you should be able to reset the router by either turning it off for a cetain time or using the reset button at the back of the router.
if you google the make and model you probably be able to find the user manual online..
