II-3-11 Roaming
The network signal for a single wireless access point might be limited by its coverage range. Therefore, if
you want to expand the wireless network in a large exhibition with a quick method, you can install multiple
access points with enabling the Roaming feature for each AP to reach the purpose of expanding wireless
signals seamlessly.
These access points connecting for each other shall be verified by pre-authentication. This page allows you
to enable the roaming feature and the pre-authentication.
Available settings are explained as follows:
Item Description
AP-assisted Client
Roaming Parameters When the link rate of wireless station is too low or the signal received by
the wireless station is too worse, VigorAP 903 will automatically detect
(based on the link rate and RSSI requirement) and cut off the network
connection for that wireless station to assist it to connect another Wireless
AP to get better signal.
Minimum Basic Rate – Check the box to use the drop down list to
specify a basic rate (Mbps). When the link rate of the wireless station is
below such value, VigorAP 903 will terminate the network connection for
that wireless station.
Disable RSSI Requirement - If it is selected, VigorAP will not terminate
the network connection based on RSSI.
Strictly Minimum RSSI - VigorAP uses RSSI (received signal strength
indicator) to decide to terminate the network connection of wireless
station. When the signal strength is below the value (dBm) set here,
VigorAP 903 will terminate the network connection for that wireless
station.
Minimum RSSI - When the signal strength of the wireless station is
below the value (dBm) set here and adjacent AP (must be DrayTek AP and
support such feature too) with higher signal strength value (defined in the
field of With Adjacent AP RSSI over) is detected by VigorAP 903,
VigorAP 903 will terminate the network connection for that wireless
station. Later, the wireless station can connect to the adjacent AP (with
better RSSI).
