Troubleshooting
CORRECTIVE ACTION
Make sure the G-120 is properly inserted and the LED(s) 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 G-120 under Network Adapter. (Steps may vary depending on the
version of Windows).
Install the G-120 in another computer.
If the error persists, you may have a hardware problem. In this case, you should
contact your local vendor.
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.
CORRECTIVE ACTION
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. Lower the output power of
each AP.
Make sure there are not too many wireless stations connected to a wireless
network.
