Fix wifi kali linux

Troubleshooting wireless driver issues in Linux can be a frustrating experience if you don’t know what to look for. This article is meant to be used as a general guideline to better help you find the information you need to solve your wireless issues. The most thorough source for wireless driver information is the aircrack-ng documentation.

90% of wireless issues reported to us are due to people not reading the Aircrack-ng documentation. You need to run airmon-ng check kill before putting your card in monitor mode.

Carefully read carefully ANY error message as they will VERY OFTEN tell you what’s wrong and how to fix it. If not, then use your Google-Fu.

1. No Interface

Stupid question: Is it a wireless card? (We’ve seen that several times)
Is the device plugged in?
Does it show up on lsusb or lspci (with the exception of phones)? You might want to update pci ids and usb ids
Does dmesg contain any information about the driver loading and/or failing
Is Kali a VM? Then, unless your card is USB, it will not be useable (VMware/VirtualBox/QEMU will virtualize EVERY PCI device). Is it attached to the VM?
If there is nothing in dmesg and it’s not in a VM, then you might want to try the latest compat-wireless (and sometimes, you’ll need firmware) -> check on Linux-Wireless drivers

2. Interface But Can’t Do Anything

Read error messages
If there are no error messages, then run dmesg | tail and it will most likely tell you what’s wrong
Firmware might be missing
Check rfkill and any hardware switches and BIOS options

3. No Monitor Mode

STA drivers (Ralink, Broadcom) and every other manufacturer’s provided driver doesn’t support monitor mode
ndiswrapper doesn’t support monitor mode AND NEVER WILL.
Airodump-ng/Wireshark don’t show any packets: check rfkill and any hardware switches and BIOS options

4. Injection

Test with aireplay-ng -9 (Make sure the card is in monitor mode with airmon-ng)
Airmon-ng doesn’t display chipset information: It’s not a big issue as it just didn’t get that information from the card and doesn’t change the abilities of your card
No injection but monitor mode: Check rfkill and any hardware switches and BIOS options
Network managers sometimes interfere with Aircrack tools. run airmon-ng check kill to kill these processes.

WiFi not working in Kali Linux 2020.4 [Fix ]

Wifi not working in kali linux 2020.4? Kali Linux 2020.4 comes with more powerful tools. Usually when we install a Linux Distro on a laptop, some of them get all of the driver installed totally, some is partially, or maybe not at all. It could be a disaster especially if the network driver isn’t installed in this internet era. I have also face the problem when i was install Kali Linux 2020.4. Kali Linux 2020.3 is a latest version of Kali Linux. In the case wifi not working in kali linux for me.

This is just happened when I installed Kali Linux 2020.4 on my HP Notebook 15-da1022tx. It is not the first time actually, back then I’ve faced this wifi not working problem when I was installed Parrot OS on my old laptop. But those time that was very easy that to install wifi. Well, I start to think this problem is not rare, it’s Open-Source after all.

Intent

This repository hosts the code for the Arch Linux AUR Package. It’s targeting Linux > 4.14 and is being developed for Arch Linux and Ubuntu 18.10. No support will be provided for other Linux distributions or Linux Kernel versions outside of that range.

So, what have you done?

First, I downloaded the image from the official website. After that, I ran Rufus to create a bootable with default setting. I configured the image source and then clicked start. Done, no error.

Next I booted my laptop from USB and followed the installation instruction. I also checked install third-party software for graphics and Wi-Fi hardware. After a few steps, Kali Linux did the installation for me.

That’s all I did, then I clicked on network icon and found out only Ethernet network that exist there. No wifi network available. What the hell….

How do you fix it?

Disclaimer

The maintainers of this repository are not Realtek employees and are maintaining this repository for their own usage. Further feature development (such as proper power saving, etc.) will not be pursued here, but will be gladly integrated if newer driver sources are provided by Realtek. Use at your own risk.

DKMS

This driver can be installed using DKMS. This is a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated. To make use of DKMS, install the dkms package.

So first I need to know what driver my laptop use by running this command

Result:

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

Now how to fix the wifi not working problem?

1. Connect internet using ethernet cable or share with smartphone usb ethernet then Open up Terminal and type command and press enter.

[email protected]:~#sudo su [email protected]:~#sudo apt-get update && apt-get update && apt-get dist-upgrade && reboot

2. It will take some time and gone reboot. After reboot kali linux then open Terminal again and type command and press enter.

[email protected]:~#sudo su [email protected]:~#git clone https://github.com/tomaspinho/rtl8821ce.git [email protected]:~#cd rtl8821ce [email protected]:~#sudo apt install bc module-assistant build-essential dkms [email protected]:~#sudo m-a prepare [email protected]:~#sudo ./dkms-install.sh

3. Wait until it’s done and then reboot your PC.

How to decrypt any ransomware free Ransomware is a form of malware that encrypts a victim’s files. The attacker then demands a ransom from the victim to restore access to the data upon payment.
Users are shown instructions for how to pay a fee to get the decryption key. The costs can range from a few hundred dollars to thousands, payable to cybercriminals in Bitcoin.

If not work then you have to disable Secure Boot option from Bios Menu do this again.

Now try click the network icon and check if there is a Wi-Fi Networks there

Its will fix your wifi not working problem in kali linux. if it not working then check your wifi adapter. Is it Realtek Semiconductor Co., Ltd. RTL8821CE or not. If not it will not working for you. You can comment here i will try to help you. if yes, your wifi adapter is RTL8821EC then remove the driver and install again.

Installation of Driver

Make sure you have a proper build environment and dkms installed.

Ubuntu & Debian

The following steps are required prior to building the driver on Ubuntu/Debian:

sudo apt install bc module-assistant build-essential dkms sudo m-a prepare

Ubuntu users may also install the prebuilt rtl8821ce-dkms package, an older version of the driver maintained by the Ubuntu MOTU Developers group for bionic, eoan and focal. It has been known to work in cases where the newer driver available here does not. Bugs and issues with that package should be reported at Launchpad rather than here.

Arch Linux

Make sure you have the base-devel package group installed before you proceed for the necessary compilation tools.

Installing from AUR

Dependencies for manual installation on Arch Linux

sudo pacman -Syu linux-headers dkms bc

If you are running a non-vanilla kernel then install the headers to match the kernel package. Proceed to the section below.

Gentoo Linux

An unofficial Gentoo package is available, using this repository as upstream. It is available from the trolltoo overlay. Gentoo does not use or require dkms for packaged drivers.

# layman -a trolltoo # emerge --ask net-wireless/rtl8821ce-driver

Manual installation of driver

In order to install the driver open a terminal in the directory with the source code and execute the following command:

Removal of Driver

Open a terminal window and git clone the repository to your local disk

git clone https://github.com/tomaspinho/rtl8821ce.git cd rtl8821ce

Then run the installation script:

Upgrading driver

Make sure you have your local copy of this repository fully updated:

If it’s still doesn’t work, there might be a different approach because those steps are work on my HP Notebook 15 Da-1022tx but I have to disable the secure boot so the driver could be installed on my Laptop. I hope this blog could help you. If you have any question feel free to comment bellow.
