Hello Nir,
With reference to your post, have you tried performing a factory reset on the unit by holding down the Reset button continuously for 8-10 secs while keeping the unit powered. If this is done already and you still see no other LED's blinking/flashing you need to contact support and get the unit replaced.
Are you able to access the web GUI of this unit? If yes, please check if you have enabled Wireless Availabiity under the Wireless SSID's configuration page.
