If you manually entered a DNS address when you set up the access point (that is,
the access point uses static IP address settings), reboot your computer and verify
the DNS address. Alternatively, you can configure your computer manually with DNS
addresses, as described in your operating system documentation.
Your computer might not use the correct TCP/IP settings.
If your computer obtains its information by DHCP, reboot the computer and verify
the address of the switch or Internet modem to which the access point is connected.
For information about TCP/IP problems, see Troubleshoot your network using the
ping utility on page 244.
You cannot log in to the access point over a
LAN connection
If you are unable to log in to the access point from a computer on your local network
and use the access point’s local browser interface, check the following:
If you are using an Ethernet-connected computer, check the Ethernet cable between
the computer and the access point.
Make sure that the IP address of your computer is in the same subnet as the access
point.
If you disabled the access point’s DHCP client and configured a fixed (static) IP
address when you connected the access point to your network (see Disable the
DHCP client and specify a fixed IP address on page 152), change the IP address and
subnet mask on your computer to so that the IP addresses of your computer and
the access point are in the same IP subnet.
If your access point’s IP address was changed (for example, the DHCP server in your
network issued an IP address to the access point) and you do not know the current
IP address, use an IP scanner application to detect the IP address. If you still cannot
find the IP address, reset the access point’s configuration to factory defaults. This
sets the access point’s IP address to 192.168.0.100. For more information, see Use
the Reset button to reset the access point on page 195.
Make sure that Java, JavaScript, or ActiveX is enabled in your browser. 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 user name is admin
and the password is the one that you specified the first time that you logged in. Make
sure that Caps Lock is off when you enter this information.
