Nelson, Emails sent in all caps are generally not good netiquette, as this is approximately the equivalent of shouting.
That said, I just successfully solved a similar problem on similar hardware. There are a few pieces of information to acquire before we're able to help you. First off, what chipset do the tablets use? Hints to this effect can be found by running the command "lsusb" from in android and noting the vendor and product ID, a pair of hex numbers, possibly like "148f:7601." It is usually the only such pair not containing "1d6b" as the first number. You can also open your tablets and inspect the wifi card directly. Usually it is a small circuit board soldered to the motherboard. If you can read numbers off the small square chip, this also should have this information. In order to get the wireless to work on my 7" A13 tablet, I also had to extract, decompile, and modify the script.bin / script.fex hardware configuration file to ensure the internal USB port was enabled by default. To do this, you will need a PC with Linux installed and a copy of https://github.com/linux-sunxi/sunxi-tools. With information about your chipset, we will be better able to help you through this process.
