If ALFA wifi cards are used for scanning wireless networks FinIntrusion-Kit, Tab Wireless -- Networks, we succesfully find APs and connected clients for first time. When we start search with ALFA wifi cards again without any changes in Configuration Country code, scanning interval etc. options, we found APs but there were no connected clients. After repeating scanning procedures the situacion was the same. But, if we change in Configuration options parameter Country code and started searching again, operation was successful and we saw again APs and connected clients. Then after repeated scanning procedure without changes in Configuration option Country code clients were gone. So if we dont change Country code before we start scanning procedure Networks, we dont find connected clients.

For first time, If we start monitoring on terminal with airmon-ng and airodump-ng Note: IntrusionKit is not started after rebooting OS with ALFA wifi card we saw associated clients. But after restarting mon interface airmon-ng stop mon0 airmon-ng start wlan0 and airodump, scanned clients were not associated despite the client was connected to AP. Similar situation as we saw in IntrusionKit. 

Note: If we used ALFA wifi card with other chipset RTL8187, everything was all right. We found APs and clients without changes in Configuration options.
