Broadcom wlan + BT coexistence

Hello.

I have this hardware…

Code:
wlan1 Dell Wireless 1704 802.11n + BT 4.0
Code:
Broadcom Corp. BCM43142 Bluetooth 4.0

Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01)

Broadcom and subsidiaries BCM43142 802.11b/g/n driver: wl

WiFi works fine, bluetooth too, but not both at the same time.
Music on bluetooth audio cuts when download a web page or a file.

I tried this:
Code:
/etc/bluetooth/main.conf

[General]
AutoEnable=true

#COEXISTENCIA CON WIFI
ohwcrypt=1
blink=1
btcoex_enable=1
bt_ant_diversity=1

Code:
/etc/modprobe.d/iwlwifi.conf

options iwlwifi bt_coex_active=1

But nothing works, or works worst

So I want to know how to configure the device coexistence to stop interference.

PLEASE, IF YOU DON’T KNOW HOW TO SOLVE THIS ISSUE DON’T POST ANYTHING.

I DON’T NEED NEWBIES SAYING “USE 5 GHZ”.
I DON’T NEED TROLLS RUNNING A LOT OF COMMAND LINES TO DISCOVER I AM USING 2.4 GHZ BECAUSE THAT IS OBVIOUS.
ONLY SERIOUS PEOPLE, NOT MODERATORS.
ONLY SERIOUS ANSWERS, NOT MODERATORS.
ONLY PEOPLE WHO KNOW ABOUT THIS, NOT MODERATORS

I DON’T WANT TO KNOW HOW GHZ ARE USING THE DEVICE, I DON’T WANT TO KNOW ANYTHING ABOUT DRIVERS INFO, READ THE POST,
I ONLY WANT TO KNOW HOW TO SET THE DEVICE COEXISTENCE TO STOP THE INTERFERENCE.
PLEASE READ THE POST.

Thank you!
