I am using WIN8 Professional Edition, And the NIC is tengda W311M USB wireless Nic. The configuration software of the original card can only be used to install the driver. The setting tool is useless in WIN8, compatible with Windows 7 and other modes are still invalid. After installing and changing different WIFI software for multiple times, I finally found ConnectifyInstaller, which can be used for your reference.
1. Open "programs and functions" in WIN8 and click "enable or disable WINDOWS functions". Check the column in front of NET framework3.5 and install it as prompted, (I also clicked the check shown below) This process is a bit slow to tell the truth.
2. Install the driver for the NIC (select the driver for the NIC)
3. Install ConnectifyInstaller and follow this setting.
If you have other methods to enable the ap function of win8, please send them to us. Thank you.
Also, your wired network must be shared !!
