Question about Arris SURFboard SB5120 Modem
Here is a link to the manual for your device - it should show you how to reset it and tell you the default password - if you have your own password then you must reset it to get back to the default password - hope this solves your problem - http://broadband.motorola.com/consumers/products/SB5120/downloads/SB5120_User_Guide.pdf

Click the "Wi-Fi" network icon located on the Window's taskbar.
Right-click the name of your network's "SSID" name and select "Properties" from the drop-down menu.
Click the "Security Tab." The network security key is now visible but unreadable.
Click the "Show Characters" check box and this will reveal your wireless password.
Log in to the router.
Routers typically have the IP address "192.168.0.1" or "192.168.1.1" for their configurations.
When connecting to the proper router IP address, a password box appears. The default login for Linksys routers is no username and "admin" for the password.
The default login for most other routers, including D-Link, Netgear and Belkin, is "admin" for the username and "password" for the password.
View or change the wireless password.
This is either a WEP key or a WPA/WPA2 password.
Some routers allow the direct viewing of the password, while others mask the password.
If the password is masked, the only option is to change the password to something else.
Connect to the wireless network with either the revealed or changed password.
Recover the System Password
Hold in the reset button on the router for 10 seconds and disconnect the power.
Continue to hold the reset button for 15 seconds while reconnecting the power.
Release the reset button and wait 60 seconds.
The router has now been reset to factory default settings.
Log in to the router as in the previous section.
Hope this helps
