Chapter 6. TroubleShooting
This chapter provides solutions to problems that may occur during the installation
and operation of ZEW2547. Read the descriptions below to solve your problems.
1. The ZEW2547 does not work properly.
Reinsert ZEW2547 into your PC’s USB slot.
Right click on My Computer and select Properties. Select the device manager and
click on the Network Adapter. You will find ZEW2547 if it is installed successfully.
If you see the yellow exclamation mark, the resources are conflicting. You will see
the status of ZEW2547. If there is a yellow question mark, please check the
following:
Make sure that your PC has a free IRQ (Interrupt ReQuest, a hardware interrupt
on a PC.)
Make sure that you have inserted the right adapter and installed the proper driver.
If ZEW2547 does not function after attempting the above steps, remove it and do
the following:
Uninstall the driver software from your PC.
Restart your PC and repeat the hardware and software installation as specified in
this User Guide.
2. I cannot communicate with the other computers linked via Ethernet in
the Infrastructure configuration.
Make sure that the PC to which ZEW2547 is associated is powered on.
Make sure that ZEW2547 is configured on the same channel and with the same
security options as with the other computers in the Infrastructure configuration.
3. What should I do when the computer with ZEW2547 installed is
unable to connect to the wireless network and/or the Internet?
Check that the LED indicators for the broadband modem are indicating normal
activity. If not, there may be a problem with the broadband connection.
Check that the LED indicators on the wireless router are functioning properly. If
not, check that the AC power and Ethernet cables are firmly connected.
Check that the IP address, subnet mask, gateway, and DNS settings are correctly
entered for the network.
In Infrastructure mode, make sure the same Service Set Identifier (SSID) is
specified on the settings for the wireless clients and access points.
In Ad-Hoc mode, both wireless clients will need to have the same SSID. Please
note that it might be necessary to set up one client to establish a BSS (Basic
Service Set) and wait briefly before setting up other clients. This prevents several
clients from trying to establish a BSS at the same time, which can result in
multiple singular BSSs being established, rather than a single BSS with multiple
clients associated to it.
Check that the Network Connection for the wireless client is configured properly.
If Security is enabled, make sure that the correct encryption keys are entered on
both ZEW2547 and the access point.
