¥ connect to the router.

¥ log in.

¥ download software.

Finally, if you have a VoDSL router, it suggests how to trouble-shoot your telephony services.

Problems Connecting to the Router

If you cannot connect your PC to the target router for configuration:

¥ For a LAN connection, verify that the routerÕs IP address matches the IP address previously stored into the

routerÕs configuration. You must have previously set the routerÕs 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 routerÕs front panel blinks when ÒpingedÓ.

¥ Check your Ethernet board IRQ settings: the PCÕs table may have become ÒconfusedÓ. If so, reboot your PC.

Problems with the Login Password

¥ Type the correct password and press enter. Remember that the password is case-sensitive. If the password is

admin, check that you are entering it 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 User Guide, Changing
