Hi @ooooooookate ,
Here’s a [https://www.dell.com/community/Inspiron/Upgrading-wireless-network-adapter/td-p/6234885|link] that may be of some help. Although the information regarding divers being available from Dell is not correct anymore. If you go with this you may have to let Windows “find” the most up to date drivers after it is installed.
Here’s a link to the [https://topics-cdn.dell.com/pdf/inspiron-15-3567-laptop_service-manual_en-us.pdf|service manual] for the laptop, taken from this [https://www.dell.com/support/home/au/en/aubsd1/product-support/product/inspiron-15-3567-laptop/docs|webpage]. Scroll to p.45 to view the necessary pre-requisite steps and then the procedure to remove / replace the wireless card.
