Simple Macbook Question

I have a new AR150. The instructions seem simple enough…plug it in…wait a minute and look for the WiFi signal. My problem is simple…there doesn’t seem to be a WiFi signal. What am I missing?

Does the red LED indicator is light up? If so, the router should broadcast its signal. Could you please use other mobile phone to check?

No red light…no wireless client on any device

It appears this unit is broken. How do I request a replacement?
