    Talking Netgear USB N150 installation problem

    I ahve got Netgear USB N150 wifi adapter for my Ubuntu 12.04 LTS desktop. But I could not install it after trying for 5 hours.
    I have many combinations done. I have already formatted it once. So if there is a tested method , I am ready to format and start again

    $ lsusb

    Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

    I then tried to install the drivers from the Realtek website. and install them . But no fruitfull results. My home wifi network is without any password. The Wifi is trying to connect and then fails.

    I then even tried to install the Windows installation given by Chii555 in a post with ndisgtk. But failed.

    But surprisingly after 5 hours research , the blue light of the Wifi adapter is not lighting up and now there is no Wireless activity. (!!!!!!!!!!!)
    ifconfig even doesnot show the adapter also.
    :~$ lsmod | grep -e ndis -e 8192
    ndiswrapper 196777 0

    Please help. I need this to work to test my project.

    That device should work well with the driver from Realtek. Ubuntu versions after 12.10 do not work with the Realtek driver unless that driver is tweaked and some problems fixed. The Realtek driver is here:

    http://www.realtek.com.tw/downloads/...Downloads=true

    This driver includes an install script which I had pretty good luck with. Ubuntu 12.04.3 also seems to have better support for the rtl8188cus chip than does the 12.04 original. I haven't used 12.04.3 enough to judge how stable the RTL8188CUs is. If you tried NDISwrapper, you may need to remove that completely before trying anything else.

    Dear Kurt18947
    I had initially installed that driver of realtek . But nothing happened. It is trying to connect and the getting disconnected.
    Presently , I am re installing the OS (Ubuntu 12.04.2) which will be automatically upgraded to 12.04.3.
    Can you please give me a step by step instruction.

    Re: Netgear USB N150 installation problem

    I'm not certain Realtek's driver will work with 12.04.3. I think the kernel version in 12.04.3 is the same as 13.04 and the Realtek driver won't build on 13.04. You might try Tim Phillips' solution posted here:

    https://code.google.com/p/realtek-81...9-ubuntu-1304/

    I did a fresh install of 12.04.3 and my Edimax 7811Un ran stable on that install for the half hour I tried it using the native driver. How well the native driver works appears to depend on what hardware it's running on.

    But the blue light at the back of the Netgear module is not lighting. The netwok toolbox is also not showing wireless option.

    I installed the realtek driver .
    After that i blacklisted the following ones rtl8192cu , rtl8192c_common , rtlwifi in /etc/modprobe.d/blacklist.conf

    then I rebooted

    robot@robot:~$ lsmod |grep 8192
    robot@robot:~$ lsmod | grep 8188
    robot@robot:~$ lsmod | grep rtl

    returned nothing

    Re: Netgear USB N150 installation problem

    I may not be seeing well but I don't see the Realtek driver loaded. There should be "8192cu" (NOT rtl8192cu, that's the open source driver) listed in lsmod. Assuming either the Realtek driver or Tim Phillips' tweak built properly, you could try loading the module manually. You could try this:
    Code:
    sudo modprobe 8192cu
    If that's the issue, the device should be active within seconds. If this works, there's a means to ensure the module loads automatically.

    Re: Netgear USB N150 installation problem

    Confirm that it is possible to get the NetGear WNA1000M adapter (USB ID 0846:9041) running with the Realtek drivers in Ubuntu 10.04. However, for me it was not trivial, I had to go through the following procedure, to make it work.

    • I have downloaded drivers from the Realtek site: http://www.realtek.com.tw/downloads/...true#RTL8192CU
    • After unpacking I went to the drivers directory and unpacked yet another .tar.gz file there, that contains actual driver code.
    • In the newly created directory (rtl8188C_8192C_8192D_usb_linux_v3.3.2_3192.201201 03 in the current version) I had to find the os_dep/linux/usb_intf.c file and add the following line to the "8192CUS Dongle" group (around line 150):


    Code:
    {USB_DEVICE(0x0846, 0x9041)},//NetGear WNA1000M


    • After that I have used the standard commands to build and install the driver:


    Code:
    make
    sudo make install

    Then I issued commands
    sudo modprobe -r rtl8192cu
    sudo modprobe 8192cu


    But the connection is very erratic. And is often disconnecting. And signal strength is very low.
    How to make the commands permanent.
    Every time I have to unplug and re plug the USB after standby mode. - Is there any solution to it?

    But I am happy atleast I can see the blue light blinking after 10 days of fighting and 3 times OS loading

    Did you ever upgrade to kernel 3.8+ ? I can confirm that the rtl8192cu driver in that kernel has support for your device (0846:9041). If it did not work properly, we could try some parameters, some external setting to make it work better. As a last resort, we could try the backported driver from kernel 3.11.

    As you figured out yourself, the proprietary realtek driver is way outdated and does not support your card by default, you had to manually add its id to make it work. And even when compiled, it does not work very well.

    As such, I'd suggest you try the native one with some tweaks first. If they fail, try the backported one.

    A frequently disconnecting dodgy driver on an unsupported, outdated system doesn't look even close to a satisfactory solution to me.
