    Re: Netgear USB N150 wireless adapter keeps asking for password ubuntu 12.04

    Sorry for the delay in responses, I was out of town for the weekend. But I'm back and ready to tackle this wireless network debacle once again!



    So here's what happened when I tried what you replied with:


    Code:
    sudo modprobe -r rtl8192cu
    results:

    no errors or results back in terminal, but the small black network connection indicator window pops up in the top right hand corner of the screen and displays “Wireless Network: Disconnected.” Also at this point wireless networks do not show in System Settings > Network. Only ethernet.


    Code:
    lsmod | grep -e rtl -e 80211
    results:

    no results were given in terminal, so I guess nothing to remove?


    Load the new driver:
    Code:
    sudo modprobe 8192cu
    results:

    no errors in terminal


    Check:
    Code:
    dmesg | grep 8192

    results:
    Code:
    [    0.829439] agpgart-intel 0000:00:00.0: detected 8192K stolen memory 
     [   17.548532] rtl8192cu: Chip version 0x10 
     [   17.766780] rtl8192cu: MAC address: 4c:60:de:5e:db:80 
     [   17.766789] rtl8192cu: Board Type 0 
     [   17.766822] rtl8192cu: Loading firmware rtlwifi/rtl8192cufw.bin 
     [   17.770848] usbcore: registered new interface driver rtl8192cu 
     [   18.168282] rtl8192cu: MAC auto ON okay! 
     [   18.212673] rtl8192cu: Tx queue select: 0x05

     [  728.985365] usbcore: registered new interface driver rtl8192cu

    After doing the above steps it unfortunately looks like we still have the same problem. Wireless doesn't pick up on it's own and wireless networks do not appear in System Settings > Network. Only "Wired" and "Network Proxy."

    This may be an issue. It looks like the same in-kernel driver was reloaded. Let's verify. Please repeat all of the commands above and check:
    Code:
    lsmod | grep 8192
    Is it rtl8192cu that's loaded or the driver you compiled, 8192cu? If it is 8192cu, the compiled version, we know it isn't helping us at all and we may as well uninstall it:
    Code:
    cd Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622/
    sudo make uninstall
    The next thing we might try is the Ubuntu version of the compat-wireless driver:
    Code:
    sudo apt-get install linux-backports-modules-cw-3.3-precise-generic-pae
    Reboot and let us know if there is any improvement.

    jon@jon-desktop:~$ sudo modprobe -r rtl8192cu
    [sudo] password for jon:
    jon@jon-desktop:~$ lsmod | grep -e rtl -e 80211
    jon@jon-desktop:~$ sudo modprobe 8192cu
    jon@jon-desktop:~$ lsmod | grep 8192
    8192cu 502394 0
    jon@jon-desktop:~$ cd Desktop
    jon@jon-desktop:~/Desktop$ cd RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622/
    jon@jon-desktop:~/Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622$ sudo make uninstall
    make: *** No rule to make target `uninstall'. Stop.

    how come it won't uninstall? I've seen this before but haven't figured out why it appears.

    Thanks again for all the help Chili!

    jon@jon-desktop:~/Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622$ sudo make uninstall
    make: *** No rule to make target `uninstall'. Stop.
    Let's see what our possibilities are:
    Code:
    ls ~/Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622
    I know there is an install.sh in there, but is there an uninstall script or ...what? If there is a README, please attach it to your reply if you can't see any uninstall instructions.

    I couldn't find any uninstall scripts in this folder. I've attached all the documentation I could find. I went through all the documentation and couldn't find anything that related to uninstalling it. You'll probably be able to find something though if it's not as obvious.

    I couldn't find any uninstall scripts in this folder.
    What all is in the folder?
    Code:
    ls ~/Desktop/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622
    Is there a tarball in there that the install.sh extracts that itself contains the Makefile; and therefor the 'make uninstall?'

    The path to the folder that was on my desktop i think is the wrong one and an earlier one that I was playing around with. The path to the one I believe is the original is listed below.

    jon@jon-desktop:~/Desktop/Jon/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622$ ls
    android_reference_codes install.sh
    android_reference_codes_ICS_nl80211 readme.txt
    document ReleaseNotes.pdf
    driver WiFi_Direct_User_Interface
    hardware_wps_pbc wireless_tools
    install wpa_supplicant_hostapd

    Re: Netgear USB N150 wireless adapter keeps asking for password ubuntu 12.04

    How about:
    Code:
    cd driver && ls

    jon@jon-desktop:~/Desktop/Jon/RTL8188C_8192C_USB_linux_v3.4.3_4369.20120622$ cd driver && ls
    rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622
    rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622.tar. gz
    And there is the file the install script extracted. Now please do:
    Code:
    cd rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622
    sudo make install
    Then install the backports package and let's cross our fingers.
