"No configuration method" but autoboot works

[f-15s/mtd]

Hi everyone, no sure if this if this is an ipxe issue or a FOG issue: I am attempting to boot into FOG using ipxe.

The computer netboots, pulls the ipxe image, and then is supposed to boot into FOG, but it fails with "No configuration methods succeeded" and the 040ee119 error. ifstat shows closed. However, if I use the dhcp command, it returns "ok" and then ifstat returns open. From here, running autoboot boots into FOG as expected.

So my question is, why doesn't this happen automatically?

Placing a dumb switch in between the computer and the network stack, makes the netboot go automatically. I have read that disabling EEE on the switch (Cisco 2690S) can fix this, but the switch does not support EEE.

I am out of my element as far as networking goes, so I am unsure how to troubleshoot.
