How to Repair Your Wireless in Ubuntu


Wireless networking in the Ubuntu operating system is designed to be intuitive and simple for the end user. Ubuntu tries to automatically connect to the network as soon as a device is detected and initiated with Ubuntu's built-in device drivers. Some wireless devices require Windows drivers, which are supported under Ubuntu. The wireless networking could cease to operate correctly for several reasons, and the user must troubleshoot the wireless networking by checking for both software and hardware malfunctions.

  • Check to ensure the wireless device is plugged-in and is on.

  • Open a Terminal by navigating to the top left corner of the screen and selecting Applications then Accessories then Terminal and type the command "sudo dhclient". This will release and renew the IP address. Check the wireless connection and if the disconnected wireless persists, continue to the next step.

  • Type the command "sudo lshw -C network" into the terminal. The output will contain the words CLAIMED, UNCLAIMED, ENABLED or DISABLED. If CLAIMED appears, the driver is loaded but not functioning and will need to be replaced or re-downloaded. If UNCLAIMED appears, no driver is loaded and a driver must be installed. If ENABLED appears, the driver is working. If DISABLED appears, the device is not on.

  • Navigate to the top left corner of the screen and select System then Administration then Windows Wireless Drivers. Select "Install new driver."

  • Choose the location of your Windows .inf file and click "Install." Click OK.

  • Reboot the computer and log in as administrator. If the wireless does not connect, continue to the next step.

  • Reset the wireless router by unplugging and re-plugging the power cable. Wait for the router to connect to the provider and renew the IP address.

  • Check the connection to confirm it has been repaired. If the connection has not been repaired, try connecting with another wireless device to confirm a hardware malfunction.
