How do I uninstall lwfinger rtlwifi drivers?

[roquet2]

Xubuntu 14.04 on Asus X200MA
Kernel: 3.16.0-45-generic

I'm often getting packet loss with an RTL8188ee wifi card, so I want to see if it's better with this driver:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware

But I read that the lwfinger driver should uninstalled first, as stated in this post:
http://ubuntuforums.org/showthread.php?t=2283759

My question is how do I uninstall it? I saw this command:

sudo make uninstall

But which directory do I need to be in when I run it?

Perhaps someone could confirm that I do indeed have the new lwfinger rtlwifi drivers installed at the moment. (I've been trying lots things so I'm not sure if I installed them with the commands below or if they were already there as part of the 3.16.0-45 kernel.)

sudo apt-get install build-essential linux-headers-generic git dkms
git clone http://github.com/lwfinger/rtlwifi_new.git
cd /path/to/rtlwifi_new
make
sudo modprobe -rv rtl8188ee
sudo make install
sudo modprobe -v rtl8188ee

Here is the relevant section from the wireless-info script:

Thanks for any help on this.

Run:

cd /path/to/rtlwifi_new
make clean
make
sudo make uninstall
sudo apt-get install --reinstall rtlwifi-new-dkms linux-firmware

Thanks for the instructions.

Sorry if this is a silly question, but is "/path/to/rtlwifi_new" the actual path or something I need to fill in myself? I did

cd /path/to/rtlwifi_new

and it says

bash: cd: /path/to/rtlwifi_new: No such file or directory

I see I've got an rtlwifi folder in /lib, here:

/lib/modules/3.16.0-45-generic/kernel/drivers/net/wireless/rtlwifi

Is that what I should be uninstalling?

Hi roquet2,

I also have an Asus X200MA with 14.04 (Ubuntu rather than Xubuntu). I also have trouble with my wireless and the RTL8188ee adapter (frequent connection drops). I started a thread about it - http://ubuntuforums.org/showthread.php?t=2289993 - and in the meantime was also trying the ppa:hanipouspilot/rtlwifi rtlwifi-new-dkms like you, to get an updated, improved driver. I just installed it this morning (just using the PPA and sudo apt-get install rtlwifi-new-dkms), and didn't have any luck yet. It seems like it's installed, but wireless can't connect at all to my network, and I uninstalled it again for the time being.

I also made changes to get my X200MA's Focaltech touchpad recognized using ppa:hanipouspilot/focaltech-dkms, including the kernel upgraded to 3.19. That worked for the touchpad. But I'm not sure whether I'm having issues related to using rtlwifi-new-dkms with kernel 3.19 instead of 3.16. Or maybe it's because I didn't install the "linux-firmware" package mentioned below. Or maybe it's that I haven't properly cleaned up another driver, like you mentioned in the title of your thread.

I'll keep watching your thread to see if you have any luck, and will make sure to update my thread if I can improve things. I was glad to see someone else trying to work out the same thing at the same time!

Thanks,
Jim
