i just bought TP-WN781ND US Model: 3.0. the stock driver that comes with the adapter has lots of issues regarding to connection. It says that it is connected but when i try to acces some webpage it just shows a no internet connection message... i downloaded the latest driver for V3 but i cant install it because when i try to do it, it just shows an error message saying that a driver is installed, even after unninstalling and deactivating the auto update driver option in windows. Also i cant find the driver files instead of the EXE installer... so i cant install the latest driver... i dont know what to do... is there a way to get the driver sys files? i need for the US 3.0 version... Thanks
