I am using two OS in my HP pavilion 15 laptop, window-7 and Ubuntu 14. In windows 7 my wi-fi is showing and working properly but in Ubuntu problem is occurring from last few days. It is not showing Wi-Fi network at all. Is there any configuration problem or anything else? Please suggest some way to fix this issue.

Since you are using a built-in wireless adapter because it is a laptop, open a terminal then enter the following command then press Enter:

  • nm-tool

This program will display the information that your Network Manager has collected regarding the wireless adapter. It will also help you in setting up your wireless network. If the result of the command shows “State: connected” then there is no problem with the adapter. It is working properly and connected to a network.

If you don’t see this message, check if your wireless adapter is enabled and that Linux Ubuntu is able to recognize it. To check if your operating system detects and recognizes your adapter, please visit Linux Ubuntu Device Recognition. Also check if drivers are available for your Wi-Fi adapter. To know if Linux Ubuntu has available drivers for your adapter, visit Install Device Drivers.

You should also check if your wireless adapter is disabled in the BIOS or by a hardware switch. Open a terminal and then run the following command then press Enter:

  • rfkill list

If the result shows “Hard blocked: yes”, you probably need to turn on a physical switch on your laptop or enable the wireless adapter during the boot sequence.
