[Windows 7 Professional 64-bit SP-1] [Duronic USB-2 Wireless 802.11N Adaptor] Have installed dongle and drivers according to Realtek instructions. Everything appears to be in place and working, but Windows can't find a wireless network whose wireless router is less than a metre away and working well with a laptop downstairs. Realtek wireless LAN icon in system tray - Available Networks tab - Searching, but nothing is found. Dongle's LED is flashing slowly. Control Panel - Manually connect to a wireless network - 'An unexpected error occurred. Not helpful. Windows diagnostics suggests driver problem - searches and finds driver - informs me the installed driver is up-to-date. The dongle connects easily when installed on an XP 32-bit machine. Wired network connection works perfectly. Regards, Jim.
