Troubleshooting
DI-701 Quick Starter Guide
Cabling
The most common problem associated with Ethernet is bad cabling. Make sure that all
conected devices are turned on. On the top of the of the DI-701 is a bank of LEDs, as a first check
verify that the Local Link and Internet Link LEDs are lit and green. If they are not, verify that
you are using the proper cables. From the DI-701 directly to a PC, the cable should be an Ethernet
cross-over cable. From the DI-701 to a hub or switch, the cable should be a straighthrough to a
normal hub/switch port, or a cross-over to an uplink port. For the DI-701 to a cable/DSL modem,
it is most common to use a cross-over, and it is recommended that you use the same cable
as supplied by your modem maker.
I can't Find the DI-701 using the DI-701 Setup Software
For the DI-701 Setup Software to find the DI-701, it has to be accessed from a client. This means
that the computer you are trying to use to run the software must be setup as in Step 6.
Additionally the computer should have been restarted to ensure that it is receiving its IP
address from the DI-701.
To verify that your computer is setup properly use the "winipcfg" utility in Windows. To run this
go to Start-->Run... and type "winipcfg" in the Run box. Press the "More Info" button on the bottom
right and make sure your network adapter that is attached to the DI-701 is selected in the Ethernet
Adapter Information box.
Look at the box labeled DHCP Server, this should be the DI-701's IP address (192.168.0.1 as default).
If it is not, or it is blank or reads 255.255.255.255 then you may have a cabling problem (see above), or you may
have another DHCP server on your network. In either case, please follow the installation guide again,
and ONLY connect the client, DI-701 and your modem. If you are on a network, it is recommended that
you contact your IS manager for further assistance with DHCP settings.
My Internet application won't work
To protect your computer from Hackers, the DI-701 uses port blocking. A port is like a door
into your computer. Each service on the Internet
has an associated port. The DI-701 protects your computer by closing certain ports off so that
malicious programs can't access your computer. Sometimes, however, you are using an application
on purpose that uses one of these blocked ports. In this case you will have to manually open
the port to allow the application to work properly.
Some applications that may be affected:
Some Email Programs
Some Multi-Player Games
Some Internet Phone/Video Conferencing Applications
The first thing you will need to do is determine what port or ports the application uses. Typically
the fastest way to find this information is to go to the software maker's web site. Go to their support
section and look for information related to NAT, Proxy Server, or Firewall. This information will
typically list 1 to 3 ports that need to be opened for proper operation of the software. If you can't
find the necessary information, call the software maker and ask what ports need to be opened for the
software to work through a firewall.
Once you have the necessary port information, it is a simple matter to actually open the ports
on the DI-701.
A. Launch the DI-701 Setup Software and press "Find". Once the DI-701 Setup Software
finds the DI-701, press "Configure":
B. Choose the "Virtual Server" tab:
C. Enter one of the port numbers that your application requries and then press the "Browse" button:
D. Choose the computer that is using the application and press "Select":
E. Press Add. Repeat this process for each individual port you need to open.
F. Press Save. Your application should now work. It may be necessary to restart your application or your computer for the application to recognize the change.
