Even if a user configuration file exists, arming and toggling GPIO9 7 times overrides the user settings and restores the module
to the factory hardcoded defaults. This bypass mechanism allows you to restore the factory defaults in case a bad
configuration is saved into the user file.
Issuing the
factory RESET
command while in command mode restores the module to a factory default state.
NOTE:
You must reboot the module or reset it for the new settings to take effect.

Party Access Points
For information regarding putting your WiSnap device in Access Point mode, please see the section on
Access Point
Networking Mode
.
NOTE:
Access points that are set to MIXED mode (WPA1 and WPA2) may cause problems during association because
some of these incorrectly report their security mode.
The WiSnap module does not currently support WPA2-Enterprise (radius server authentication, EAP- TLS)
The WiSnap should work with any standard Access Point. We have tested the WiSnap with the following access points:
Cisco Aeronet series
Linksys (both standard and openWRT Linux)
Netgear WGR614 v8
Netgear WGN54
D-Link DIR-615
Airlink 101
Apple Airport Express
