Most likely, the issue is your wireless connection. I suggest that you try temporarily connecting your notebook directly to your Internet modem/router by Ethernet, and then, try Recovery Mode again.
Some of the reasons for having issues using a wireless connection are:
- The wireless network is configured to use a hidden (non-broadcast) network name or SSID.
- The wireless network is secured with either WEP or WPA-Enterprise.
- The connection requires certificate-based authentication / 802.1x
- The connection requires the use of Proxies (where specific proxy servers must be configured in network preferences)
- Captive Wi-Fi networks (where you click an “Agree” button to access the Internet)
- PPPoE (where there is no router handling the PPPoE connection)
- Failure of the router to provide a workable DNS server address, or providing 0.0.0.0. This typically is seen with a -2002f or -2003f error message.
