It's not Realtek nor your motherboard's fault. Install like this. 1) Uninstall all Realtek WLAN software. 2) Reboot. Extract the driver I said to a folder. 3) Open Device Manager. Right click the Realtek lan or Unknown Device if it changed to that. Choose Update Driver software. Browse my computer. Let me pick. Have disk. Browse. Now find and double click on the .inf in the extracted folder. Hit ok, then next and magically, it will be installed properly.
