4.27.4.7 Roaming - AP Discovery
This parameter controls how aggressively the device scans for new access points, normal or fast.
4.27.4.8 Roaming - Packet Loss
This parameter controls how many packet failures will trigger a roaming event. Leaving the value at
Normal
is the standard default baseline that works well in most cases. Changing the value to
Aggressive
will cause the roaming attempts to be more aggressive — fewer packet losses will trigger the roam attempt.
4.27.4.9 2.4GHz Channel Selection
This limits the number of channels that the radio will scan for the selected WLAN network SSID. By limiting
the number of channels that the radio has to scan, response time is improved during roaming.

WiFi Connect A.R.C.
The WiFiConnectARC utility on the desktop provides a quick method to configure a device for use on a
private network, primarily for use with Active Remote Configuration (A.R.C.).
When you click on this icon, WiFiConnect A.R.C. configures the default WiFi interface. The WEP key is set to
PsionPsion123
. The SSID is set to
Psion
. The default interface becomes the active interface. Keep in mind
that you must configure the access point and the Vehicle-Mount(s) to use the same settings.
Refer to the
Active Remote Configuration (A.R.C.) Administrators Guide

times, you may need to renew your connection by logging in again.
