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.

This article, which is part of the series on Linux device drivers, deals with the various concepts related to character drivers and their implementation. Shweta, at her PC in her hostel room, was all set to explore the characters of Linux character drivers, before it was taught in class.

Install Wireless Driver Kali Linux

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.

This document explains how to install NVIDIA GPU drivers and CUDA support, allowing integration with popular penetration testing tools.

Prerequisites

First, you’ll need to ensure that your system is fully upgraded and that your card supports CUDA.
Note: GPUs with a CUDA compute capability > 5.0 are recommended, but GPUs with less will still work.

Let’s determine the exact GPU installed, and check the kernel modules it’s using.

Kali Linux Driver Package

Device Drivers Linux

Installation

Once the system has rebooted, we will proceed to install the OpenCL ICD Loader, Drivers, and the CUDA toolkit.

During installation of the drivers the system created new kernel modules, so another reboot is required.

Verify Driver Installation

Now that our system should be ready to go, we need to verify the drivers have been loaded correctly. We can quickly verify this by running the nvidia-smi tool.

With the output displaying our driver and GPU correctly, we can now dive into benchmarking. Before we get too far ahead, let’s double check to make sure hashcat and CUDA are working together.

It appears everything is working, let’s go ahead and run a benchmark test.

Benchmarking

There are a multitude of configurations to improve cracking speed, not mentioned in this guide. However, we encourage you to take a look at the hashcat documentation for your specific cases.

Troubleshooting

In the event setup isn’t going as planned, we’ll install clinfo for detailed troubleshooting information.

OpenCL Loaders

It may be necessary to check for additional packages that may be conflicting with our setup. Let’s first check to see what OpenCL Loader we have installed. The NVIDIA OpenCL Loader and the generic OpenCL Loader will both work for our system.

If mesa-opencl-icd is installed run:

Since we have determined that we have a compatible ICD loader installed, we can easily determine which loader is currently being used.

As expected, our setup is using the open source loader that was installed earlier. Now, let’s get some detailed information about the system.

Querying GPU Information

We’ll use nvidia-smi once again, but with a much more verbose output.

It looks like our GPU is being recognized correctly, so let’s use glxinfo to determine if 3D Rendering is enabled.

The combination of these tools should assist the troubleshooting process greatly. If you still experience issues, we recommend searching for similar setups and any nuances that may affect your specific system.
