Problems Connecting to the Router
If you cannot connect your PC to the target router for configuration:
• For a LAN connection, verify that the router’s IP address matches the IP address previously stored into the
router’s configuration. You must have previously set the router’s Ethernet LAN IP address and subnet mask,
saved the Ethernet configuration changes, and rebooted the router for the new IP address to take effect.
• Check that your LAN cable is pinned correctly and each pin end is securely plugged in.
Note:
If you are using a straight-through cable, the colors for pins 1, 2, 3, and 6 should match on both
connectors. If you are using a crossover cable, the colors for pins 1, 2, 3, and 6 on one connector should
match respectively 3, 6, 1, and 2 on the other connector.
• Make sure the PC and target router are on the same IP subnetwork or the target router is reachable through a
router on your LAN. They can, however, be on different networks if IP routing is
off
.
• Check Network TCP/IP properties under Windows 95 and the control panel of the TCP/IP driver installed
under Windows 3.1.
• Check if the LAN LED on the router’s front panel blinks when “pinged”.
• Check your Ethernet board IRQ settings: the PC’s table may have become “confused”. If so, reboot your PC.
Problems with the Login Password
You have been prompted for the login password and received the following message: “Login Password is
invalid”.
• Re-enter the correct password and press
enter
. Remember that the password is case-sensitive. Check that you
are entering
admin
in lowercase and that the Caps key is not active.
• If you have forgotten the password, you must reset the login password. Refer to the
