unable to complete getting the ephemeral images

My setup:
Trusty on an IBM Thinkpad x201.
Onboard Gigabit is static on 10.0.0.0 (The private MAAS lan)
Internet connectivity is via an 802.11n WiFi dongle
My internet connection is a 10Mbit ADSL line

I have installed and configured maas. The next step, per the instructions here:

maas.ubuntu.com/docs/instal.html#import-the-boot-images

is this:

$ maas-cli maas nde-groups import-boot-images

While doing this, I observed that it first called maas-import-pxe-files which ran to completion pulling all the PXE files and putting them in /var/lib/maas/tftp/*

Next, it calls maas-import-ephemerals

This ran and did NOTHING. It just sat there, no network traffic in or out, no disk activity, no data written to /var/lib/maas/ephemeral. I left it sitting for over an hour and it never actually started downloading any images .

I finally killed off the process and ran maas-import-ephemerals manually. This time, it did begin downloading images, converting them and copying them to /var/lib/maas/ephemerals. But then it just stopped as though it had lost the connection th wherever it's downloading from, or something. It never exited, it just ... paused and never restarted. I let THIS sit for an hour and noticed that there was absolutely NO further related network activity, disk activity or aything.

So I finally killed that process off as well.

Next, I tried breaking it down into smaller chunks like so:

$ sudo maas-import-ephemerals release=RELEASE

Doing it this way, I was able to fully download Saucy, Raring, Quantal and Precise. Currently, trying with trusty does nothing (it doesn't seem to do anything at all.
