Hi @ Harshul Gupta,
If the WLAN is being shown as enabled in the BIOS and its’ status in Device Manager is being shown as not connected then perhaps you have a loose or faulty WLAN module.
Here’s a [https://support.hp.com/us-en/document/c03467259?jumpid=in_r12064_us/en/psg/hw_diags/secondary-banner/testing-for-hardware-failures|link] that shows how to perform hardware tests in HP computers. Click on ''Running Component tests > Complete List of Component tests >'' scroll down to ''Wireless Module test'' to view how to test the module
If the WLAN module test indicates that it is faulty here’s a link to the [http://h10032.www1.hp.com/ctg/Manual/c05493762|service manual] for your laptop, taken from this [https://support.hp.com/us-en/product/hp-pavilion-15-cc100-laptop-pc/16842299/model/19460078/manuals|webpage]
Scroll to p.42 to view the necessary pre-requisite steps and then the procedure to remove/replace the WLAN module. Follow the steps to check that the module’s connection to the motherboard is OK and if it is you may have to replace the module
Also on p.42 you’ll find the part numbers for the module.
If you search online using the appropriate part number ''only'' in the search box of your browser, you’ll get results for suppliers of the part
