@Chris-Stratton I take that back! Or at least some of it. Was sitting here wondering which of the 30 problems I'm going to tackle next. I wondered, since that failed device has cooled.....
I grabbed the device out of it's new home, one of the fried expansion docks, and put it back in the breadboard dock. Applied power, and voila! The LED came up and went into the same failure pattern as before. Is there a possible heat issue?
Immediately I tried to replicate this magical feat. Now the device is back to providing no external clues - looks dead.
I was asking this question few months ago. I was desperately needed a good wifi driver with my own kernel build. When I was dealing with this problem, the mac80211 wasn't just slow, it was also dropping connections and crashing the OS.
I've spent a LOT of time dealing with this issue, and in the end I managed to take LinkIt Smart OpenWRT image, configure it to my needs and deploy it on Omega2. It was a real hassle, because there are some hw differences and they're using an old kernel version (3.xx) with pre-compiled Ralink wifi binaries.
I meant was that I want to have Openwrt or LEDE but without the OnionConsole or other extra software.
As I could see LEDE project is only available for Onion Omega 2 and Omega 2+ but not for the original Omega. Maybe I didn't search on the right place but I couldn't find anything related to LEDE for the original Omega.
since omega install states already installed i would try to remove that .ipk and then install it thinking that it may be a bad install or the already installed message is wrong. it seems that something in the current install is broken so try to get rid of the install and try fresh install.
There are five conditions that lead to the generation of a NACK:
No receiver is present on the bus with the transmitted address so there is no device to respond with an acknowledge.
The receiver is unable to receive or transmit because it is performing some real-time function and is not ready to start communication with the master.

Omega2 requires solid 3.3V stable voltage output at 300mA.
And one more critical spec... power supply needs to be able to handle in-rush current during WiFi power-up without voltage drop.
That fleabay $0.99 item needs a large capacitor (I recommend 220uF 6.3V) on its input side and a large capacitor on its output side (I recommend 470uF 6.3V.) The link between that unit and Omega 2 cannot be too thin gauge (I recommend 22 ga) and definitely use soldering as opposed to using DuPoint connectors.
My error was I was working so much in the ssh world for a few hours that it didn't occur to me until late that this was not an OS issue but an application issue. Setting up key pairs, no matter how many times I've done it, is so damn error prone that a repetitive motion disorder takes over.
I would add for others making this trip that a global change may benefit them. In my case the actual command was:
