43.2 SBG3500-N Series Access and Login
I forgot the IP address for the SBG3500-N Series.
1 The default LAN IP address is 192.168.1.1.
2 If you changed the IP address and have forgotten it, you might get the IP address of the SBG3500-
N Series by looking up the IP address of the default gateway for your computer. To do this in most
Windows computers, click Start > Run, enter cmd, and then enter ipconfig. The IP address of the
Default Gateway might be the IP address of the SBG3500-N Series (it depends on the network),
so enter this IP address in your Internet browser.
3 If this does not work, you have to reset the device to its factory defaults. See Section 1.6 on page
24.
I forgot the password.
1 The default admin password is 1234.
2 If this does not work, you have to reset the device to its factory defaults. See Section 1.6 on page

• If you changed the IP address (Section 8.2 on page 161), use the new IP address.
• If you changed the IP address and have forgotten it, see the troubleshooting suggestions for I

1.3 on page 21.
3 Make sure your Internet browser does not block pop-up windows and has JavaScripts and Java
enabled. See Appendix C on page 387.
4 If it is possible to log in from another interface, check the service control settings for HTTP and
HTTPS (Maintenance > Remote MGMT).
