sudo add-apt-repository ppa:kelebek333\/drivers<\/pre>\nStep 3: Update the cache<\/h3>\n
Ubuntu now automatically refreshes the apt cache while adding PPA. But, Linux Mint does not. In the case, manually run the command below to refresh cache:<\/p>\n
sudo apt update<\/pre>\nStep 4: Select install driver package for your chipset<\/h3>\n
After adding the PPA and updating cache, either install and use the graphical Synaptic Package Manager<\/b> (available in App Center) to search & install the WiFi driver:<\/p>\n

<\/p>\n
Or, run apt install<\/code> command to install a driver package (rtl8188eu for example):<\/p>\nsudo apt install rtl8188eu-dkms<\/pre>\nKeep an eye on output info while installing the package. It tells where to install the Kernel modules.<\/p>\n
Step 5: Load the driver (Kernel Module)<\/h3>\n
After installing the driver package, restart your computer<\/b>. Then, you may find out the modules via:<\/p>\nls \/usr\/lib\/modules\/$(uname -r)\/updates\/dkms<\/pre>\nThe command should outputs the previously installed Kernel modules in .ko<\/code> files.<\/p>\nYou can finally, load the driver (8188eu<\/code> for example<\/i>) via command:<\/p>\nsudo modprobe 8188eu<\/pre>\nAnd, verify via lsmod<\/code> command with ‘grep’ filter:<\/p>\nlsmod |grep '8188eu'<\/pre>\nIf you have loaded the correct network driver, Wi-Fi should work now!<\/p>\n
How to Uninstall:<\/h2>\n
To unload the driver module, use modprobe<\/code> command with -r<\/code> flag. For example, unload ‘8188eu’ via command:<\/p>\nsudo modprobe -r 8188eu<\/pre>\nAnd, to remove the driver package, either use “Synaptic Package Manager” or run apt remove<\/code> command:<\/p>\nsudo apt remove package_name<\/i><\/pre>\nTo remove the Ubuntu PPAs, use command:<\/p>\n
sudo add-apt-repository --remove ppa:kelebek333\/kablosuz<\/pre>\nsudo add-apt-repository --remove ppa:kelebek333\/drivers<\/pre>\nThat’s all. Enjoy!<\/p>","protected":false},"excerpt":{"rendered":"
