After some collaborative work between several people on this forum, the problem may have been found that caused some people to "error" their wifi after rooting. It appears that mid-run, Craig changed the wifi adapter in their tablets, and the rooted ROM that was posted by m3red only covers about 50% of the tablets. m3red's posted ROM contains wireless drivers for RALINK hardware, and these will not work if you have Realtek wireless hardware, resulting in the "error". REMEMBER! If you are not having this issue, there is no need to do this, continuing may cause you to lose working wifi. For those that have their wifi giving them an "error" message, try the following steps: Step 1. Download the original ROM of the Realtek wireless tablets here: realtekcraig738b.img Step 2. Rename the file "update.img", without quotes. Step 3. Place the file on a micro-SD card, preferably empty. Step 4. Power the tablet down if turned on, and place the micro-SD card in the tablet. Step 5. Turn on the tablet, and wait for it to prompt you with an update message. You may need to let the device completely boot before the message appears. Step 6. Accept the message, and the device should reboot and begin installing the firmware. Step 7. Once the install is complete, it should reboot again, and may take several minutes to finish booting. Step 8. After you complete the setup procedure, you should have a tablet with working wifi again. Step 9. Post here as to whether or not this procedure worked for you. Remember, this is not rooted, this is just a fix for those that have broken wifi. This is not guaranteed to work, though it seems to have already helped several people.
