Hardy It belongs to my Wireless-USB utility, which shows all details about connections. It has a systray-icon, which shows how good connection is. My USB-108M-Wireless adapter is TP-Link TL-WN620G-11G. When I stop the acs.exe-process, my indicator in the systray is gone and with it all information, configuration etc. BTW, a cheap but very good adapter, connection even through several walls is very good.  See also: Link
