It's branded as "Webpass from Google Fiber", so either term works.
What does Airrave 4 do that MagicBox Gold doesn't?
It frankly took way too much calling to get this. My journey to MB gold was a long one. I had a MB before. To get a "Gold", I had to return the original. I did that, and then had to call to ordered the Gold. I called, but got sent the same non-gold again. I returned that, and then was when return went through, was told Gold is out of stock and they can't order it until it's back in stock. Called a month later, but still out of stock. Called a month later, but nothing arrived, order never placed or was lost. Called again, but again, nothing arrived, order was lost or never placed. Called the 3rd time, and this time the order arrived. Getting an Arrive 4 might take long enough that I might as well just wait for the firmware upgrade that will enable/fix Wi-Fi.
