• If you changed the IP address and have forgotten it, see the troubleshooting
suggestions for I forgot the IP address for the P-792H v2.
2 Check the hardware connections, and make sure the LEDs are behaving as
expected. See the Quick Start Guide.
3 Make sure your Internet browser does not block pop-up windows and has
JavaScripts and Java enabled. See Appendix D on page 435.
• If there is a DHCP server on your network, make sure your computer is using
a dynamic IP address. See Appendix C on page 411. Your P-792H v2 is a
DHCP server by default.
• If there is no DHCP server on your network, make sure your computer’s IP
address is in the same subnet as the P-792H v2. See Appendix C on page
411.
4 Reset the device to its factory defaults, and try to access the P-792H v2 with the
default IP address. See Section 1.5 on page 28.
5 If the problem continues, contact the network administrator or vendor, or try one
of the advanced suggestions.
Advanced Suggestions
• Try to access the P-792H v2 using another service, such as Telnet. If you can
access the P-792H v2, check the remote management settings and firewall rules
to find out why the P-792H v2 does not respond to HTTP.
• If your computer is connected to the WAN port, use a computer that is
connected to a ETHERNET port.
I can see the Login screen, but I cannot log in to the P-792H v2.
1 Make sure you have entered the password correctly. The default admin password
is 1234, and the default user password is user. The field is case-sensitive, so
make sure [Caps Lock] is not on.
2 You cannot log in to the web configurator while someone is using Telnet to access
the P-792H v2. Log out of the P-792H v2 in the other session, or ask the person
who is logged in to log out.
3 Turn the P-792H v2 off and on.
4 If this does not work, you have to reset the device to its factory defaults. See
Section 1.5 on page 28.
