Ok, lets try something else. I know these are the same steps in the link provided by Wm, but did you have internet connection when carrying them out?
Again with an ethernet cable plugged in to have internet connection, give the following commands:

Code: Select all
sudo apt-get install build-essential linux-headers-generic git
mkdir ~/RTL8188EU
cd ~/RTL8188EU
git clone git://github.com/lwfinger/rtl8188eu
cd ~/RTL8188EU/rtl8188eu
make
sudo make install
sudo cp -v ~/RTL8188EU/rtl8188eu/rtl8188eufw.bin /lib/firmware/rtlwifi/
sudo depmod -a
sudo update-initramfs -u
sudo modprobe 8188eu


Hopefully your wireless should start working.

Great stuff! I have to admit that I wasn't connected to the internet on the initial try (I thought the code was just making changes to the Zorin configuration on my USB installation). When I got connected all of the steps worked until near the end when an attempted write to the USB stick failed because it was Read Only. After a bit of reading I realized that I had to allow space for persistent changes to my stick. After reinstalling and selecting the right booting option, running your commands, removing and installing the USB wireless interface it all works like a charm. Many thanks to you MV and WM for the help and patience!

Sorry to come back with the same issue (I feel like I'm in the bread line asking for toast). It is only this evening that I have had an opportunity to really test Zorin with the TL-WN725N wifi adapter and I am still having issues. When I initially boot from the USB drive with Zorin the adapter comes on at full bars. However, after approximately 30 seconds the strength drops quickly to one or two bars and communication to the internet stops. If I wait for 3 or 4 minutes the bars will go up, sometimes to full, and I can connect again only to have it drop again within 30 seconds again. If I manually stop and start the connection it invariably comes alive with full bars but again drops within 30 seconds to an unusable level. This adapter on this laptop running Windows 7 works without a hitch. I'm hoping these symptoms may indicate some solution to someone here.

When you are connected, please post back here the result of the following terminal command:

I suspect that you have other modules getting in the way of r8188eu (your driver), and create a conflict.
Can you please post the result of:
Code: Select all
lsmod


We may have to blacklist in /etc/modprobe.d/blacklist.conf the other modules.
Probably :
blacklist rtl8192cu
blacklist rtl8192c_common
blacklist rtlwifi

Also here is a listing of "/etc/modprobe.d/blacklist.conf". I'm not sure if the changes you suggested above can simply be entered to this file or if it has to be changed through the command line and if there is any specific sequence required:

# This file lists those modules which we don't want to be loaded by
# alias expansion, usually so some other driver will be loaded for the
# device instead.

# evbug is a debug tool that should be loaded explicitly
blacklist evbug

# these drivers are very simple, the HID drivers are usually preferred
blacklist usbmouse
blacklist usbkbd

# replaced by e100
blacklist eepro100

# replaced by tulip
blacklist de4x5

# causes no end of confusion by creating unexpected network interfaces
blacklist eth1394

# snd_intel8x0m can interfere with snd_intel8x0, doesn't seem to support much
# hardware on its own (Ubuntu bug #2011, #6810)
blacklist snd_intel8x0m

# Conflicts with dvb driver (which is better for handling this device)
blacklist snd_aw2

# causes failure to suspend on HP compaq nc6000 (Ubuntu: #10306)
blacklist i2c_i801

# replaced by p54pci
blacklist prism54

# replaced by b43 and ssb.
blacklist bcm43xx

# most apps now use garmin usb driver directly (Ubuntu: #114565)
blacklist garmin_gps

# replaced by asus-laptop (Ubuntu: #184721)
blacklist asus_acpi

# low-quality, just noise when being used for sound playback, causes
# hangs at desktop session start (Ubuntu: #246969)
blacklist snd_pcsp

# ugly and loud noise, getting on everyone's nerves; this should be done by a
# nice pulseaudio bing (Ubuntu: #77010)
blacklist pcspkr

# EDAC driver for amd76x clashes with the agp driver preventing the aperture
# from being initialised (Ubuntu: #297750). Blacklist so that the driver
# continues to build and is installable for the few cases where its
# really needed.
blacklist amd76x_edac

Even if I don't see the modules running, just to be sure do the following:

Open terminal and run
Code: Select all
sudo gedit /etc/modprobe.d/blacklist.conf


Write your password. The document will open with administrative rights so you can edit it.
At the end of the file add the following 3 separate lines:

Code: Select all
blacklist rtl8192cu
blacklist rtl8192c_common
blacklist rtlwifi


Save, close and exit.
Reboot and see if that helped.

I ran the command and go the following:

live@live:~$ sudo gedit /etc/modprobe.d/blacklist.conf

** (gedit:13197): WARNING **: Can't load fallback CSS resource: Failed to import: The resource at '/org/gnome/adwaita/gtk-fallback.css' does not exist

** (gedit:13197): WARNING **: Can't load fallback CSS resource: Failed to import: The resource at '/org/gnome/adwaita/gtk-fallback.css' does not exist

(gedit:13197): IBUS-WARNING **: The owner of /home/live/.config/ibus/bus is not root!

However, the file did open and I was allowed to add the three blacklist lines and save them. I confirmed that they were in the file after rebooting. The signal drops are still happening.
