Average Reviews:
(More customer reviews)The hardware itself works great. However, the installation CD comes with Alfa's own utility, RaUI.exe. Using this utility can cause major problems with your system. Basically, once installed, the utility ties up your system resources. It can use up to 90% of your CPU time constantly. This causes the CPU to overheat and shut your system down (power off) without warning. This can result in lost data in other open applications as well as presenting a serious risk to your CPU overheating and getting fried, which could be an expensive repair.
Also, the CD which comes with it has some serious flaws. You can't exit the installation unless the CD is still in the CD drive you are installing it from. You can't even Ctrl-Alt_Del to access the System Manager and end the task unless the CD is still present.
Furthermore, the Auto-Run function of the installation CD has a fatal error. You can't Auto-Run the CD. It will come up with a Windows error if you try to setup using the screen which is presented from an Auto-Run. You can install the driver ok without problems, but you can't install the utility from the screen which gives you that option. You have to open the CD with explorer and click on the setup to run the setup without getting an error.
If you install the utility on the CD your PC will later crash due to the overheating of the CPU. This problem doesn't appear at first, but only after you restart your computer and the utility RaUI.exe is initiated as part of the start-up. At that point it takes over your system resources and causes the 80%+ overhead on your CPU.
My recommendation is that the hardware itself and it's drivers are very good, but the utility is dangerous. Just install the driver, but NOT the utility. Then use the Windows Wireless Network Wizard to install Windows' own utility. Once the drivers are installed, Window's own built in functions can use the hardware and provide all of it's functionality without the problems inherent in the RaUI.exe utility.
The RaUI.exe utility is more user friendly and easier to setup and use than the Windows' built in wizard, but the serious flaw in how it uses so much of your system resources isn't worth the convenience.
Again, the hardware itself, and it's drivers are very good. But the Alfa utility not only sucks, but poses a serious hazard to your system. Get someone who knows what they are doing to help you and install only the drivers from the provided CD but avoid the utility on the CD and use the Windows Wireless Setup Wizard instead to avoid serious problems which could lead to expensive repairs of your computer.
