Connection Problems
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.
