Hi.
You actually were fairly close on your answer to what is actually needed.
I use 192.168.1.1
Almost 100% of the time, this is the access address for the router that a computer is hooked up to.
Now, you will need to know the username and password, and that I can't help you with as I am not the one that set it up.
However, is it is still on the factory settings, and the username and password haven't been changed from the factory setting, then I can tell you what to type into for those spaces.
The factory settings are:for username : admin
:for password :
leave the password space blank.
Then, you can go and configure it any way that you wish.
Just remember to write the new ones down, that way if you need to do it again, you won't have to hunt for ways to acces the router again.
Also, here is a link for the manual for your router.
It is in pdf form, so you can either view it online, or you can download it and view it while offline.

Good luck to you, and have a good day!
