Has anyone opened a unit and noted the wifi chipset (or made a high-res photo of the board(s))? (I'll do it if I *have* to, but I get a bit squeamish about opening the cases to these commodity electronics--they always seem to have scads o' hidden tabs just waiting to get broken off...)

I posted 2 pic of the inside of mine. Look on the Craig main thread.

I've read all these posts (I think). I think I have a possible solution, but it requires a little forethought...
These tablets obviously have atleast 2 different wifi chipsets. For my example, lets assume 2: Type A, and Type B. Lets call everyone that has working wifi Type A. Non working wifi Type B.
The images here are probably packed with the driver for 'Type A.' It would make sense that if you update a 'Type B' with the image for 'Type A,' the correct drivers are never loaded. I am also assuming that the 'Original Restore' image would have the driver for a 'Type A,' so it wouldnt work with the 'Type B' unit.
I hope I havent lost anyone yet...
To fix all of the 'Type B' units, someone needs to extract the driver from the tablet BEFORE updating to the 'Type A' image.
I have no clue as to how the rom kitchen thing works, but somehow add the 'Type B' driver to the image.
I am wondering if the image can have both drivers, or does there need to be 2 or more images?
I have this tablet, UnModded. I cant tell which wifi mine has, but I am willing to attempt to extract the necessary file(s) and share with anyone willing to rebuild the rom. All I need is some instructions on where to start. It would also be helpful to explain how to make a custom backup, so we can take matters into our own hands as far as backups go.
I hope my train of thought hasnt derailed anyone...

I dont plan on ever opening mine, unless theres a wad of 20's in there....
Mine is still under warrantee. Dont fix what aint broke. I'm sure I can find out what the driver is without cracking the case.
It also crossed my mind; what if there are more than 2 kinds of wifi chips? Cross that bridge when we get to it, I guess....
Also, If you want me to see another forum, please drop me a link.

Go to the link that Salty has posted. It has a rom you can download and try. It restored mine to the original state AND restored the wifi/cleared the error problem. Next is rooted rom with this update, hopefully. 
If you already have a brick, it won't hurt to try it.

When you get a chance can you edit your original post to include instructions on how to tell the difference between wifi units. Add the Rom Meepinator Posted as the original rom for realtek hardware. I will PM you the link to the 8188 realtek rooted rom.
