Wired LANs
If your computer and your Keyspan USB Server are both wired to your network via a physical
cable and you are not able to see the Keyspan USB server, you may have issues with your
network hardware (ie your ethernet hub, ethernet switch, or router).
To test this, connect the Keyspan USB Server directly to your computer via an ethernet cable. At
this point, check the Keyspan USB Server application can see if your server appears. If it does
not show up, disconnect the USB Server's power supply for 10 seconds then plug back in. Wait
10 seconds for the USB Server to boot up then see if the USB Server appears in the Keyspan
software.
If your server does not show up, contact Keyspan technical support for further assistance.
If your server does show up, try moving your USB server and computer to the same ethernet
hub/switch. If this does not solve your problem, contact Keyspan technical support for further
assistance.
Tech Note : Some USB hubs and switches may not properly route UDP and TCP
traffic when connected to other hubs and switches. This is especially true when your
USB server is using Zeroconfig to obtain an IP address. To avoid these issues,
connect your USB Server and your computer to the same Ethernet hub/switch.
WANs
If you're trying to access your USB server across a WAN (ie you want to access your USB server
at home when you are at work), you'll need to create a connection between the two networks that
allows both broadcast UDP and TCP/IP traffic to the network where the USB server resides.
If your router at work and your router home both support the ability to route broadcast UDP and
TCP/IP traffic between the two networks, you will be able to use your USB server across a WAN.
This will require that you configure both routers to allow traffic on UDP port 3842 and TCP/IP
port 3842. Please refer to your router's documentation for further details.
If you routers do not support this, you may be able to use a software-based solution such as a
VPN type type solution. Please note that most VPN software do not support broadcast UDP.
If you need to connect your USB server between two networks and are still having a problem,
please contact Keyspan technical support for further assistance.
Networking Wrap Up
If you are still have problems with your USB Server, try resetting the USB Server hardware and
then repeating the troubleshooting process. For instructions on how to reset your USB Server
hardware, please skip ahead to the Resetting The USB Server Hardware sub-section.
