The adapter intermittently turned off when using the 5GHz band. The problem was solved in the following way. I found the ASUS USB-AC56 page on Wikidevi () which states that the device is based on the Realtek RTL8812AU chip. There is also a link to the latest drivers for this chipset: . Tw/DOWNLOADS/downloadsView. Aspx? Langid=1&PNid=21&PFid=64&Level=5&Conn=4&DownTypeID=3&GetDown=false. After installing them, the problems with disconnects are gone. I installed these drivers through the device manager as an ate over the old ones.
