    Hi,

    uninstall ndiswrapper completely:
    Code:
    sudo modprobe -rf ndiswrapper
    sudo apt-get remove --purge ndiswrapper-common ndiswrapper-utils-1.9 ndisgtk
    sudo rm /etc/modprobe.d/ndiswrapper.conf
    sudo rm -r /etc/ndiswrapper/* 
    sudo depmod -a
    sudo update-initramfs -u
    Please show the outputs of:
    Code:
    lspci -nnk | grep -iA2 net
    lsusb
    lsmod
    dmesg | egrep rtl8|r8'
    iwconfig
    rfkill list

    Re: Realtek rtl8192ce slow as hell... non useable... Ubuntu 11.04... PLEASE HELP..

    What drivers did you install? You can try two things (after uninstalling ndiswrapper as described):

    1.) Copy the firmware to another place:

    Code:
    sudo mkdir /lib/firmware/RTL8192SU
    sudo cp /lib/firmware/RTL8192SE/rtl8192sfw.bin /lib/firmware/RTL8192SU/
    Check the connection.

    2.) Update the driver:

    Code:
    sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential
    wget http://media.cdn.ubuntu-de.org/forum/attachments/2844083/rtl_92ce_92se_92de_Ubuntu_11.x_mac80211_0004.0816.2011.tar.gz
    tar xvf rtl_92ce_92se_92de_Ubuntu_11.x_mac80211_0004.0816.2011.tar.gz
    cd rtl_92ce_92se_92de_Ubuntu_11.x_mac80211_0004.0816.2011
    make
    sudo make install
    sudo cp -r firmware/* /lib/firmware
    and reboot.

    ifconfig -a
    iwlist chan
    sudo iwlist scan
    dmesg | egrep 'rtl8|r8'
