To access your router, if you cant or don't know how to, try typing in your browser address bar: 192.168.2.1
If that doesn't work, try these:
192.168.0.1
192.168.1.1
192.168.1.0
Try some of these passwords, if you have never set your own password for the router:
admin
password
1234
user
(leave password box blank)
If you have already assigned your router a password, and you forgot it, then you'll need to reset it. Most routers have a small hole or button on the back for that. Paper clips work the best.
