Router problem (SOLVED)

I'm trying to portforward, first it tells me to choose my router

http://www.portforward.com/routers.htm

But I don't which router I'm supposed to choose because I don't know it.

The web site tells me that I can know it by go to my Default Gateway. Which I can access to by typing http://192.168.1.1 . But when I type that into my firefox, it asks me for usernam and password, which I dont' know.

And also, since I can't go there, I can't configure my router, which I don't know what it is either. ><

Can someone help me. I'm really sucked at these network stuff. -___-

I'm not sure exactly, but that is the same IP that I have to use to access my router settings. Try using the word "admin" without the quotes as your password, leave your username field blank. If this works for you, though, you will want to put in a username and enter a new password for your router.

Yes that is the correct default login for linksys wireless and ethernet routers.

If it is a wireless setup, you should secure the router with your own username and password, as well as an encryption key for the network. Anyone who taps in to use your network can do what they will under the guise that they are you.

Thank you for helping. I can log in now. :)
