Can you open a terminal (Ctrl+Alt+T) and send the output from these commands:
Code: [Select]
lsusb
and
Code: [Select]
sudo lshw -C network
and
Code: [Select]
iwconfig
and
Code: [Select]
iwlist scanning
and
Code: [Select]
rfkill list

If it will make it easier .. connect to your router with an ethernet cable whilst doing this.

Just getting the correct driver now .. but whilst you wait, install linux-headers-generic and build-essential by running this command:
Code: [Select]
sudo apt-get install linux-headers-generic build-essential
You MUST have an active internet connection for the above command to work.

Make sure ALL package managers are closed .. then run it again

Package managers include

Update Manager
Software Centre
Synaptic (if installed)

Or you could just reboot, and not open any of the above whilst running the command ;)

OK, be SURE to run the command in my last but one response whilst connected to your router with an ethernet cable BEFORE running these commands.

Here it is again, just in case (won't hurt if you run it again .. it will just tell you they are already installed):
Code: [Select]
sudo apt-get install linux-headers-generic build-essential

You'll still need an active internet connection for the "wget" command below .. so propbably best to stay connected to the router until you've finished running the commands below.

I must add, I haven't tested this build against a 3.5 kernel, but they compile against the 3.2 kernel .. and they're either going to compile or not, so can't do any harm ;)

Open a terminal (Ctrl+Alt+T) and run these commands in sequence.
Code: [Select]
mkdir ~/TL-WN725N_driver
then
Code: [Select]
cd ~/TL-WN725N_driver
then
Code: [Select]
wget https://dl.dropboxusercontent.com/u/11876059/rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105.tar.gz
then
Code: [Select]
tar -xvf rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105.tar.gz
then
Code: [Select]
cd ~/TL-WN725N_driver/rtl8188C_8192C_usb_linux_v3.4.4_4749.20121105
then
Code: [Select]
make
then
Code: [Select]
sudo make install
then
Code: [Select]
sudo modprobe -r rtl8192cu
then
Code: [Select]
sudo modprobe 8192cu

Did wireless spring to life ?

If so .. check it survives a reboot.

Can you post the output from:
Code: [Select]
modinfo 8192cu
and
Code: [Select]
lsmod | grep 8192
