The cheap price of Amazon convinced me to buy. But when it first installs there were problems: The second adapter fell after about 15 minutes in the standby mode. Even after internet research (similar problem is known) is no solution except Duch Complete the circuit separate (= Reset) and re-connect, then worked again for 15 minutes. After consultation with the manufacturer's hotline (competent and well) and installing a new software still does not solve problems. After return shipping and exchange it works now without problems, the advertised data rates, however, are impossible to achieve by far (but is about 50% faster than AV 200) that occasionally changes to the green home icon red, but the function does not seem to affect.
