If the error persists, you may have a hardware problem. In this case, you
should contact your local vendor.
Cannot change to
Access Point mode
If you use the Windows XP configuration tool and the ZyXEL Utility to
configure the ZyXEL G-220F at the same time, the ZyXEL G-220F
automatically operates in wireless station mode. You need to disable the
Windows XP configuration tool to change between the modes using the
ZyXEL Utility (refer to the Section 1.6 for more information).

PROBLEM CORRECTIVE ACTION
When using the Windows
XP configuration tool, cannot
scan for or connect to any
access points.
The ZyXEL G-220F might still be operating in access point mode. This
results when you set the ZyXEL G-220F 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
ZyXEL G-220F to operate in station mode before you close and exit the
ZyXEL Utility.
