Inspiron 15-7567, Qualcomm QCA61x4A disconnects

Dear Dell Community,

I have a `Inspiron 15-7567 Series BCC` product and my wifi keeps disconnecting every ~5 minutes. It is random. Needless to say that other OSes/devices do not exhibit the same behavior (android phones, windows computers, iphones, etc). This is not a router issue.

Can you help me? I cannot find the drivers as suggested on:

<https://www.dell.com/community/Inspiron/Where-are-my-Inspiron-Laptop-drivers/m-p/6073966#M19741>

Because of course the vendor does not provide me with a specific, unique product number to find them... Unheard of /s
