.Rssi R/O Property
Function:
Indicates the strength of the signal being received from
the wireless network that the Wi-Fi interface is currently
associated with, or wireless peer in case of the ad-hoc
network.
Type:
Byte
Value Range:
0-255, default= 0.

Associating With Selected Network
Details
The signal strength is expressed in 256 aribitrary levels that do not correspond to
any standard measurement unit.
This property is only updated while the Wi-Fi interface is in the associated state (
= 1- PL_WLN_ASSOCIATED), or running an ad-hoc network
(
= 2- PL_WLN_OWN_NETWORK). There is another read-
only property --
-- that will contain the signal strength for the
specific wireless network having been scanned for with the
method.
.Scan Method
Function:
Causes the Wi-Fi interface to commence either the search
for available wireless networks or obtainment of
additional information about a particular network
specified by its SSID.
Syntax:
wln.scan(byref ssid as string) as accepted_rejected
Returns:
One of accepted_rejected constants:
0- ACCEPTED.
1- REJECTED.

Description
ssid
Network name.
Details
If the ssid argument is left empty, the wln object will search for all available
wireless networks. If the ssid argument is set, the wln object will obtain additional
information about this network.
The scan process is a
. As such, the wln.scan will be rejected (return 1-
REJECTED) if another task is currently in progress. The task will also be rejected if
the Wi-Fi interface is in the associated state (
= 1-
PL_WLN_ASSOCIATED), is running its own network (
= 2-
PL_WLN_OWN_NETWORK), or if the Wi-Fi hardware is not online (
=
0- NO). The method will return 0- ACCEPTED if the task is accepted for processing.
