N750 Wireless Dual Band Gigabit Access Point WNDR4300-TN
Cannot Log In to the Access Point
If you are unable to log in to the access point from a computer on your local network, check
the following:
•
If you are using an Ethernet-connected computer, check the Ethernet connection
between the computer and the access point. For more information, see
Check Ethernet
Cable Connections
on page
38.
•
Make sure that your computer’s IP address is on the same subnet as the access point.
•
If your computer’s IP address is shown as 169.254.x.x, recent versions of Windows and
Mac OS generate and assign an IP address if the computer cannot reach a DHCP server.
These autogenerated addresses are in the range of 169.254.x.x. If your IP address is in
this range, check the connection from the computer to the access point, and reboot your
computer.
•
If your access point’s IP address was changed and you do not know the current IP
address, clear the access point’s configuration to factory defaults. This sets the access
point’s IP address to 192.168.0.51. See
Factory Settings
on page
43.
•
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click the
Refresh
button to be sure that the Java applet is loaded.
•
Try quitting the browser and launching it again.
•
Make sure that you are using the correct login information. The factory default login name
is admin and the password is password. Make sure that Caps Lock is off when you enter
this information.
Changes Not Saved
If the access point does not save the changes you make in the access point interface, check
the following:
•
When entering configuration settings, always click the
Apply
button before moving to
another screen or tab, or your changes are lost.
•
Click the
Refresh
or
Reload
button in the web browser. The changes might have
occurred, but the old settings might be in the web browser’s cache.
Incorrect Date or Time
To display the current date and time, select
ADVANCED > Security > Schedule
. The
access point uses the Network Time Protocol (NTP) to obtain the current time from one of
several network time servers on the Internet. Each entry in the log is stamped with the date
and time of day. Problems with the date and time function can include the following:
•
Date shown is January 1, 1970. This means the access point has not yet successfully
reached a network time server. Check that your Internet access is configured correctly.
