How a fix -2006f and -2006d error?

I installed windows 10 on my mac, and I cannot choose the operational system, so I erased the ssd. And now I can't re-install the operational system, just show a file blinking and when I try the command + R start the internet recovery and show the error -2006d. Anyone else can help me?


Obs. The english is not my language, sorry for the mistakes.

MacBook Pro, macOS Sierra (10.12.6)

Those errors in the low thousands are usually an indication that your Wi-Fi is less than adequate for automatic Internet Recovery. Perceived Defects include:


Hidden Network-name

Manual IP address rather than good old DHCP

required login page or additional password

required use of PPPoE on the computer (on Router is fine)

use of 802.1X profile or external validation

required use of proxy


no DNS numbers provided by Router, or 0.0.0.0 supplied


sometimes you can use an Ethernet cable and it will work fine.
