My HH1620 does not work.
If none of the LEDs light up, make sure that:
The HH1620 is plugged into a power socket outlet.
You are using the correct power supply for your HH1620 device.
The HH1620 is turned on via the push button at the back panel.
Note: The power requirements for your HH1620 are clearly indicated on the
identification label on the bottom of the HH1620.
If the LAN LED does not light up, make sure that:
The LAN cable is securely connected to the 10/100Base-T port.
You are using the correct cable type for your Ethernet equipment, that is UTP CAT5 with
RJ-45 connectors.
My computer is experiencing difficulty connecting to the wireless network.
Ensure that your router is powered on and that the Wireless LED is on.
Ensure that your wireless adapter (PCI card, Notebook or Ethernet adapter) is installed
correctly and is active.
Ensure that your wireless adapter's radio signal is enabled. Review your adapter's
documentation for further instructions.
Ensure that your wireless adapter for your PC and the wireless router have the same
security settings that will allow your computer to access the wireless network. Also,
verify that the list of Restricted Wireless MAC Addresses (on the WIRELESS Page of
the Web-based Configuration Utility is not configured to block your PC.
Ensure that your wireless adapter is within range of your router or is not behind an
obstruction. For example, metal structures will interfere with the signal, as will 2.4 GHz
cordless phones, and microwaves.
Ensure that your router's antenna is connected and that your PC's wireless adapter
antenna is also connected.
My computer is experiencing difficulty in connecting to the router.
Ensure that all of your cabling connections are firmly connected. This includes the
cables from the wall to your modem, between the router and modem, and, if available,
from the router to your PC.
Ensure that your LEDs are not lit Red or not at all. For further information about LED
descriptions, see Section 1: Overview.
Ensure that you are using Ethernet cables and not telephone cables between the router
and modem or router and PC. See the illustration below. Ethernet cables use a wider
RJ-45 style plug using 8 wires where telephone style plugs use the smaller RJ-11 style
plug using 4 to 6 wires.
