It seems that T4U AC1300 V3 with a USB3 is quite difficult to make it work inLinux system since so no reported method could work and rare efforts to make an edit to let it work.
I got difficulty in findg a driver for it in Linux system, moreover, i am a retired materialist knowing computer science little.
But i need to have double wireless networks in series to have a Big Hacker leave me alone. I made my best to analyze the structure of a drive and tried to find solutions somehow. So far I am still not knowing much about how to create a driver,i.e. the necessary elements, but i spent a lot of time to campare several almost but no successful drivers at that time and made some modifications to make them work the first time for T4U ac1300 v3.
Of course the original author knew their driver much more than me. However, i do my best and a lot of time testing drivers seriously and not one only but still found severals as the followings, even moreover, some drivers can work for all 3 adapters, i.e. T4U ac1300 but also for dwa 172 and dwa 171 very popular in Taiwan or Mainland. All of working drivers are special thanks to The EDITORS IN GIBHUB.COM who help to make them as formal drivers.
