Ok Thanks to Lucas_sylvie for opening up his tablet and verifying that Craig has indeed been shipping CMP738B tablets with what appears to be 2 Different Wifi cards installed.
Now moving forward we need to stop Flashing the Roms already posted to CMP738B tablets with the Realtek usb wifi installed. The easiest way I have found is take your new unflashed, unrooted tablet and install this Term.apk from your sd card with the APK installer app. Make sure you are hooked up to Wifi and reboot tablet. After a reboot open the newly installed Terminal Emulator and at the prompt type "dmesg" without the quotes. It is going to print out alot of information but you need to look for this.
[69] =======================================================
[69] ==== Launching Wi-Fi driver! (Powered by Rockchip) ====
[69] =======================================================
[69] RT3070 WiFi driver (Powered by Rockchip,Ver 2.12) init.
If you see this then you are probably ok, Normal warnings still apply "MAY BRICK YOUR TABLET!!!!!" "YOU WILL VOID YOUR WARRANTY" AND "DO NOT FLASH ROMS FOR CMP738A" "MAY KILL YOUR WIFI"
If you see something else STOP!!!! Don't flash anything. First post what it says, the people trying to fix this problem have either already lost their wifi or have this Wifi Chipset and have working Wifi. Simply put we just can't replicate the issue.
Now for the tough part. If you have a tablet that reports something else and you want a rooted Rom with working Wifi the you are going to need to Dump the Rom from your Device and post it up to be modified.
This will not only protect you by having an Original Rom to go back to if need be. It will also Help out those who have lost their Wifi.
When someone posts here that they have found the difference and are willing to get their hands a little dirty Dumping the rom I will post instructions on how to do that.
If you have already lost your Wifi it will show what I posted above.
Thanks To Salty it appears if you open Security Guard and go to Operating system version Realtek users will have 8188 at the end of it.
