When called with the argument set to the name of a particular network, the wln.scan and wln.activescan methods will attempt to find this wireless network and obtain its operational parameters:
'scan for a specific network
wln.activescan("Tibbo1") 'you could use wln.scan(''), unless you are expecting to be dealing with a hidden network
If wln.scanresultssid<>"" Then
After the scan...
|•||Wln.scanresultssid R/O property will contain the name of the specified network, or nothing if the network wasn't found. If the network was found, the following five properties will also be updated:|
|•||Wln.scanresultbssid R/O property will contain the BSSID ("MAC address") of the specified network.|
|•||Wln.scanresultchannel R/O property will return the number of the RF channel on which the network operates.|
|•||Wln.scanresultrssi R/O property will contain the strength of the RF signal received from the specified network.|
Both wln.scan and wln.activescan will collect exactly the same data about the specified network. The only difference is that wln.scan won't be able to do the job if this wireless network does not broadcast its SSID. Wln.activescan, on the contrary, will get this done. So, if you need to work with a hidden network, then you need to know this network's name, and you need to use wln.activescan to obtain this network's data.
