When does the problem occur? 'Qualcomm' or 'Realtek'? Anyway, if your problem is can't install driver of 3DP Net, I think there is a auto installation problem with your system. If your problem is this, please use manual update in 'Device manager'. When you use manual update, 'Device manager' has a question 'where is the driver folder'. The folder is 'C:\3DP\Net\2101\Realtek\Gigabit\1064'. [If the problem occur with 'Realtek']
