    16.04.2 64-bit, kernel 4.8, rtl8192cu, connected to wifi but no internet

    So I tried to install the fixed rtl8192cu driver and follow the code commands searching other posts with the same problem. I did this:
    Code:
    sudo apt-get install --reinstall linux-headers-$(uname -r) linux-headers-generic build-essential dkms git 
    git clone https://github.com/pvaret/rtl8192cu-fixes.git
    sudo dkms add ./rtl8192cu-fixes
    sudo dkms install 8192cu/1.10
    echo "blacklist rtl8192cu" | sudo tee -a /etc/modprobe.d/blacklist.conf
    After a reboot, my connection strength lowered to one bar and Internet ceased to work. Is there a way to revert back to the previous driver because it was working better than the driver I installed.

    When I had 16.04.1 32-bit, kernel 4.4, the rtl8192cu-fixes driver worked flawlessly. So does this problem have to do with 32-bit/64-bit versions or the kernel?

    Re: 16.04.2 64-bit, kernel 4.8, rtl8192cu, connected to wifi but no internet

    I use that same driver and I did an upgrade a few days ago and my system reverted back to using the old driver but with dkms installed that should not happen, please run the wireless script in my signature and we will take a look, I have to leave for a little while but anyone here can help you.

    Before you tried to reinstall that driver you should have removed the old one you installed first.

    Re: 16.04.2 64-bit, kernel 4.8, rtl8192cu, connected to wifi but no internet

    When my wireless got messed up it installed this driver rtl8xxxu as well I blacklisted it then I reinstalled the fixed driver after changing to the path of the fixed driver and doing:
    Code:
    sudo make clean
    It is dkms that failed you can leave that package out of the command and see if it will build then but you will have to do make clean and run the make commands every time there is an upgrade to the kernel.

    I think it is likely that the fixed driver you installed will work good again like mine does if you just blacklist rtl8xxxu, if you look the 8192cu driver is loaded but the other driver is conflicting with it.

    I get the following:

    Code:
    make: *** No rule to make target 'clean'.  Stop.
    I agree the fixed driver I installed will work but intermittently. I'm stuck at a 1Mb/s connection which is a bottleneck.

    Re: 16.04.2 64-bit, kernel 4.8, rtl8192cu, connected to wifi but no internet

    Thats because the rtl8xxxu driver is also loaded, do:
    Code:
    echo "blacklist rtl8xxxu" | sudo tee -a /etc/modprobe.d/blacklist.conf
    if you still have the fixed driver installed, then reboot.

    Did the

    Code:
    echo "blacklist rtl8xxxu" | sudo tee -a /etc/modprobe.d/blacklist.conf
    and rebooted. Connection strength is at full bars and I get 144Mb/s in the Connection Information dialog box.

    MUCH APPRECIATED Wildmanne39!!!
