This chapter covers potential problems and the possible remedies. After each problem 
description, some instructions are provided to help you to diagnose and to solve the problem.

Table 23   Troubleshooting Starting ZyXEL Utility  

Cannot start the 

ZyXEL Wireless 

LAN utility

Make sure the AG-220 is properly inserted and the LED is on. Refer to the Quick 

Start Guide for the LED descriptions.
Use the Device Manager to check for possible hardware conflicts. Click Start, 

Settings, Control Panel, System, Hardware and Device Manager. Verify the 

status of the AG-220 under Network Adapter. (Steps may vary depending on the 

version of Windows). 
Install the AG-220 in another computer.
If the error persists, you may have a hardware problem. In this case, you should 

contact your local vendor.

The ZyXEL utility 

icon does not 

display.

If you have installed the Funk Odyssey Client software on the computer, uninstall 

(remove) both the Funk Odyssey Client software and ZyXEL utility, and then install 

the ZyXEL utility again after restarting the computer.

Table 24   Troubleshooting Access Point Connection Problem 

When using the 

Windows XP 

configuration tool, 

the AG-220 cannot 

scan for or 

connect to any 

access points.

The AG-220 might still be operating in access point mode. This results when you 

set the AG-220 to operate in access point mode using the ZyXEL utility, close the 

ZyXEL utility and then use the Windows XP configuration tool.
Before you use the Windows XP configuration tool, make sure you set the AG-220 

to operate in station mode before you close and exit the ZyXEL utility.
