Why Is My Kali Linux Not Connecting To Wi-Fi?

Kali Linux just like any other Linux system, will have networking and other software issues at one point or another. It is important to become proficient in the command line and troubleshooting root cause analysis. This will make you better at computing and will allow your system to run smoothly.

There are several things you can do if your Kali machine isn’t connectin to the Wi-Fi. These range from running specific network interface commands to resetting hardware. We will cover how to effectively troubleshoot your Kali machines network issues.

Here are the steps you should look at when you have discovered your Wi-Fi connection is non-existent. The first thing you should do is test the Wi-Fi connection on a different device to determine if the Wi-Fi connection is the issue or your device is.

You can do this by grabbing a phone or other computing device and connecting to the Wi-Fi. If you can connect to it, then it is most likely not the Wi-Fi access point causing the issue on your Linux machine. Follow these steps next:

  • Verify that the wireless adapter is recognized by the system: Run the command ‘iwconfig’ or ‘lshw -C network’ to check if the wireless adapter is recognized by the system. If it is not recognized, you may need to install the appropriate drivers for the adapter.

  • Check the status of the wireless adapter: Run the command ‘ifconfig wlan0’ (assuming your wireless adapter is named wlan0) to check the status of the adapter. If it is down, use the command ‘ifconfig wlan0 up’ to bring the adapter up.

  • Check the wireless network settings: Run the command ‘iwlist wlan0 scan’ (assuming your wireless adapter is named wlan0) to scan for available wireless networks. Make sure that your network SSID is on the list, and that the wireless security settings match the ones configured on your router.

  • Check the DHCP client: Make sure that the DHCP client on your Kali Linux machine is running and is configured correctly. You can check the DHCP client status by running the command ‘service networking status’ or ‘systemctl status networking.service’.

  • Check the DNS settings: Make sure that the DNS settings on your Kali Linux machine are configured correctly. You can check the DNS settings by running the command ‘cat /etc/resolv.conf’.

  • Check the firewall: Make sure that the firewall on your Kali Linux machine is not blocking incoming connections. You can check the firewall status by running the command ‘ufw status’

  • Restart the network: Try restarting the network service by running the command ‘service networking restart’ or ‘systemctl restart networking.service’

  • Try to update your wireless firmware: firmware updates often contain bug fixes that can solve wireless connectivity issues.

It’s worth to mention that the above steps are general troubleshooting steps, the actual steps that you need to do might vary depending on the specific issue you are facing.

Check Running Processes

It is generally a good idea in a Linux system to check the running processes. This is helpful for finding programs and services that may be conflicting with the Wi-Fi connection, causing it to malfunction.

Sometimes when multiple processes are trying to access the network adapters, they “fight” over the connection priority and can cause issues. These issues can manifest themselves by not allowing an internet connection, slow performance, or program crashing.

The “ps” and “top” commands can be used to troubleshoot various performance and resource-related issues on a Linux system, however, they are not specifically designed for troubleshooting Wi-Fi issues.

The “ps” command is used to display information about the currently running processes on a Linux system, including the process ID, user, and command line arguments. It can be useful for identifying any processes that may be causing performance issues or conflicts with the Wi-Fi system.

The “top” command is similar to “ps” but it provides a real-time, dynamic view of the processes running on a system and their resource usage, such as CPU and memory usage. It can be useful for identifying any processes that are using a significant amount of resources, which could be affecting the performance of the Wi-Fi system.

In general, these commands can help you to identify any processes that are using a lot of resources and could be affecting the performance of the Wi-Fi system, however, they are not the best tools to troubleshoot Wi-Fi specifically.

You can check the status of the wireless adapter, check the wireless network settings, check the DHCP client, check the DNS settings, check the firewall (the Linux built in firewall is called IP Tables) and update your wireless firmware as I mentioned previously.
