Chapter 7. TroubleShooting 

 

This chapter provides solutions to problems that may occur during the 
installation and operation of ZEW1603. Read the descriptions below to solve 
your problems.   
 

1. The ZEW1603 does not work properly. 

Reinsert ZEW1603 into your PC’s PCI slot. 
Right click on My Computer and select Properties. Select the device manager 
and click on the Network Adapter. You will find ZEW1603 if it is installed 
successfully. If you see the yellow exclamation mark, the resources are 
conflicting. You will see the status of ZEW1603. 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 ZEW1603 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 ZEW1603 is associated is powered on. 
Make sure that ZEW1603 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 ZEW1603 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 ZEW1603 and the access point.
