Before the adapters, virtually no network in my office ... After installation, 5 bars! Only downside, the instruction information accompanying the product on which it would be essential to indicate that a certain amount of time between when the startup is performed and the appearance of the product on the computer ... The start is not instantaneous ... it would be better to know, to avoid calling the adapters in their box ... Explanations also very confusing for network security ... Some specific schemes would be more meaningful explanations too complicated and thus almost unusable. So be armed with a little patience to decode and ultimately, everything works perfectly!
