    put the script (sh file) and the patch (txt file) in the same folder as the downloaded file ( RTL8192xC_USB_linux_v3.4.4_4749.20121105.zip from http://tinyurl.com/c4v34vq )

    run the script as root or sudo

    don't forget to blacklist the native drivers:
    put a file in to /etc/modprobe.d/ with this in it
    Code:
    # Blacklist native RealTek 8188CUs drivers
    blacklist rtl8192cu
    blacklist rtl8192c_common
    blacklist rtlwifi
    Thank You guys so much!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!1 This needs to be a STICKY!

    Worked perfectly! Thank you so much! And I agree with making this a sticky. I'll attach the install output. There was a "install script not executable" message but everything works. I installed using gdebi. I initially tried without a network connection, copying on a USB drive. I got an error message that it was unable to download files. Plugged in another network adapter and it installed as expected.

    thanks for the feedback. glad it has helped.
    i've modified it - just for cosmetic reasons to remove that error message that kurt mentioned.
    cheers,

    Re: RealTek RTL-8188CUs working well-how to

    Oscar,
    Wrong driver for your device i think.
    Your TL-WN723N device has an RTL8188SU chipset not RTL8188CUS.

    Re: RealTek RTL-8188CUs working well-how to

    Tim is correct. Here is some information about your device:

    http://wikidevi.com/wiki/TP-LINK_TL-WN723N_v1

    Note the caution about multiple versions of the same model # using different chip sets. That bugs me but the majority of users (windows & mac) don't know and don't care. I see these entries:

    brcmsmac 550698 0
    brcmutil 14755 1 brcmsmac and similar.

    I'm wondering if your device has a Broadcom chipset.

    Re: RealTek RTL-8188CUs working well-how to

    Tim and Kurt

    Thankssss, so much, I solved it!, you are right I was installing wrong driver, I search the correct driver for my TL-WN723N ver 3. although the driver isn't RTL8188CUS, the correct driver for me is RTL8188EU,

    How I solved exactly?

    I download driver for TP-LINK_TL-WN723N_v3 the first file in gitub:

    Xubuntu 12.10 use this -> https://github.com/liwei/rpi-rtl8188eu
    Xubuntu 13.04 use this -> https://github.com/purchae/rtl8188eu

    And unzip file,
    $ cd directory_driver_unzipped
    $ sudo make
    $ make install

    Reboot my pc and worked it

    PD:
    brcmsmac 550698 0
    brcmutil 14755 1 brcmsmac and similar.
    Because I testing the USB wireless adapter in my laptop (although it have the wireless "broadcom chipset" fine ) this install testing is for a customer, and just I have my laptop for this case

    Nice detective work Oscar. No shortage of RTL8188 variants, is there? Perhaps your adapter supports 13 WiFi channels vs. 11 channels in N. America?

    Re: RealTek RTL-8188CUs working well-how to

    This worked great thanks a lot! I just bought a monoprice branded RealTek RTL8192CU to replace a ralink adapter that got crushed (it still worked but the signal wasnt great).

    My speed isnt as good as I expected but that may be unrelated.
