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

Re: Dell Inspiron 15 7000 series wifi disconnecting

In order to fix I have to:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
nmcli radio wifi off ; sleep 5s ; nmcli radio wifi on
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Sometimes it goes havoc and I have to restart my computer . . .

Re: Dell Inspiron 15 7000 series wifi disconnecting

After digging up the PT BR website I got the product number and driver options:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
https://www.dell.com/support/home/br/pt/brbsdt1/product-support/product/inspiron-15-7559-laptop/driv...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

However the Ubuntu version supported is 12.04 and it is different than the one shipped to me. In any case there are no drivers listed there. None.

PS: just so you guys can have the feeling:
