Table 16   Troubleshooting Starting ZyXEL Utility Program 

Cannot start the 

ZyXEL Wireless 

LAN Utility

Make sure the ZyXEL G-270S is properly inserted and the LED is on. 
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 ZyXEL G-270S under Network Adapter. (Steps may vary depending 

on the version of Windows). 
Install the ZyXEL G-270S 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 install 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 17   Troubleshooting Link Quality 

The link quality 

and/or signal 

strength is poor all 

the time.

Search and connect to another AP with a better link quality using the Site Survey 

screen.
Move your computer closer to the AP or the peer computer(s) within the 

transmission range.
There may be too much radio interference (for example microwave or another AP 

using the same channel) around your wireless network. Relocate or reduce the 

radio interference.
