    With that kind of link quality, I am amazed that you can even connect! What is the distance of the router/access-point from the notebook? Is it the same access-point that connects fine in windows? What is the signal strength in windows when connected to the same access-point?

    Re: Realtek Wireless PCIe - Not working / Constant disconnects

    I am pretty much at the furthest point from the router in the house

    But, again, the Windows machine surfs the web without a problem - and that is really all I need. The windows machine is in the same exact location as the Linux machine. Yes, they both connect to the same access point.

    The windows machine from this location gets about 80% at all times.

    Re: Realtek Wireless PCIe - Not working / Constant disconnects

    We created a config file earlier. I'm wondering if it is needed anymore. Let's remove it for now and see if defaults can deliver any better connectivity -
    Code:
    sudo rm /etc/modprobe.d/rtl8192ce.conf
    Then do -
    Code:
    sudo modprobe -rfv rtl8192ce
    sudo modprobe -v rtl8192ce
    If that doesn't help, or even worsens the situation, please post -
    Code:
    grep -iR [0-9a-z] /sys/module/rtl8192ce/parameters/
    With this, I'm off to bed now. It's already 12:12 am here, and I'm too tired to continue. See you tomorrow!

    Re: Realtek Wireless PCIe - Not working / Constant disconnects

    Unfortunately, that didn't help.

    Here is the results from the command:

    /sys/module/rtl8192ce/parameters/ips:Y
    /sys/module/rtl8192ce/parameters/fwlps:Y
    /sys/module/rtl8192ce/parameters/swenc:N
    /sys/module/rtl8192ce/parameters/swlps:N


    Thanks for your continued help! Talk to you tomorrow.

    Any way I can use the Windows drivers in Linux?

    Re: Realtek Wireless PCIe - Not working / Constant disconnects

    Went with a clean install of the system.

    Downloaded the latest Realtek driver from here: http://www.realtek.com.tw/downloads/...Downloads=true
    In my case that happens to be: RTL8192CE-VA4 for the Rosewill Wireless RNX-N250PCe

    Put the file in my Home directory.

    Followed the instructions from the ReadMe file and what Varun laid out.

    1. Right click TAR file and "Extract Here" (in Home directory)
    2. Go to terminal and CD into that newly created folder
    3. sudo su
    4. make
    5. make install
    6. reboot

    *Worth noting, I ditched WICD (due to issues last time I tried the Realtek driver) and am sticking with the NetworkManager.*

    My wireless signal is representative of what I think it should be. Wireless is working well at the moment. I am hopeful I am on the right track this time with the Realtek driver from OEM.

    I will post back in a week or so.

    Re: Realtek Wireless PCIe - Not working / Constant disconnects

    Don't even have to wait a week. I can't believe it took me this long to use the OEM driver. Working like a charm.

    Solved.

    Maybe because you were stuck with someone trying to do 'experiments' with the native driver (hoping an easier, permanent fix)

    But anyway, -
    Working like a charm.

    ..so sweet to the ears!

    Just be aware, you will have to rebuild and reinstall the driver with every kernel upgrade. Assuming newer kernel headers will get installed by default, then-
    extract the files (to start fresh) > 'cd' to the extracted directory > sudo su > make > make install > exit
    ..followed by a reboot if necessary should be all that should be needed.

    Another note - the path to the extracted files should 'never' contain spaces, else the build will fail. Just an extra tip
