If I spent more than 150 euro in this thing is because Securifi promised us that. Finnaly I had to buy an Asus router that did the job, your "marvelous" router was just a waste of time and money because they didn't the job you promised
Don't tell us that your priority is the customer, you has been playing with us form more than three years. And don't blame the chipset maker. The ones promising were you, not them
