I put an absolute three, because it works, but it's like keeping a cat not accustomed to a tray at home, you never know what trick will throw this device out and when . It usually happens at the most inopportune moment. If I change, and it works well, I will change the review. If not, I will switch to a cheaper and more reliable one, anyway, I did not see such a strong difference in the speed flow. I'll call D-Link technical support one of these days. Still wondering how to reset to "Factory settings".
