Error 3403f MacBook Air Internet Recovery Message

I had to wipe my MacBook Air and now when I start it I have a question mark symbol inside a folder that blinks.  I've attempted all corners of Internet Recovery Mode but no matter what option I choose,  I get an error -3403f apple.com/support. This is what I've tried so far and I'm looking for an answer in which I can still use Internet Recovery Mode as taking it to an Apple Store or buying/finding an external hard drive and/or flash drive is not an option for the moment.

I've attempted:

Password-Free WiFi
Password-Protected WiFi (WPA/WPA2 Personal)
2.4GHz, 5GHz
All channels including auto.
Other networks (including a hotspot from my phone).
Safe Mode
Target Disk Mode
Terminal Mode
Ethernet into ISP modem and ethernet into Airport Extreme (2013).

The MacBook Air is 2012 Summer and did include Internet Recovery when I purchased it.

Sounds like your ISP is blocking some ports that Internet Recovery needs. Click here to see whats on the Apple Forums.

I noticed that forum post earlier.  I have a hotspot with Verizon and T-Mobile (both separate devices), and Time Warner Cable internet service.  Is it just luck all three of these ISP's are blocking the port which communicates with Apple's servers to re-download the OS X installation file?

If all of the ISP's above do in fact block the port.  Which one do I need to open?  I'm thinking the port needs to be opened on the actual modem/router, not the Apple AirPort Extreme?

Hi

If ISP block certain ports you cannot open them in any way.
Are you near an apple serice point? I am sure they will do the internet recovery on the spot as a service.

You should also check your dns server settings. If you have too many dns hops between your network and the Apple servers, Apple will deny downloads from their servers.

Meaning you need to dns servers your iso provides. No google dns or opendns or whatever you may have set.

Solution is to install the OS with a disc or hard drive after purchase of the OS and perform a local install.

Sure, but that bypasses the question. Internet recovery is there to replace disks.

But a disk install surely solves the problem.

It's highly unlikely that T-Mobile, Time Warner Cable, and Verizon with WPA/WPA2 credentials which are required to download the OS from Apple, have banned the port to communicate with Apple servers for the re-installation.  Bought an external micro SD card reader, formatted it as Mac Journaled, after purchasing OS, mounted it with SD card and performed boot installation locally and now have the Mac back in order.
