Ubuntu 18.04 suspend hardblocking bcm43142 wifi

[hopefeda]

Hello everyone,

I am using ubuntu 18.04 on a dual booted HP Pavilion Notebook -17-g005nx (ENERGY STAR). (ubuntu/windows 10) UEFI with secure boot.I'm also using a cheap chinese usb wifi adapter/antenna for better wireless connection.

Upon bootup from OFF state, both cards work properly. However, after a wakeup from suspend both get disabled and produce the following:

user@computer:~$ rfkill list all
4:phy2: Wireless LAN
Softblocked: no
Hardblocked: no
13:phy7: Wireless LAN
Softblocked: no
Hardblocked: no
14:brcmwl-0: Wireless LAN
Softblocked: no
Hardblocked: yes

What I tried:

After checking:

user@computer:~$ lspci -knn

..scrolling down to bcm43142

08:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43142802.11b/g/n [14e4:4365] (rev 01)
            Subsystem:Hewlett-Packard Company BCM43142 802.11b/g/n [103c:804a]
            Kernelmodules: bcma, wl

...reseting bcma/wl module

user@computer:~$ sudo modprobe -r bcma
user@computer:~$ sudo modprobe bcma
user@computer:~$ sudo modprobe -r wl
user@computer:~$ sudo modprobe wl

but it didn't work..

However: disabling wl module, which disables BCM43142, enables the cheap usb wifi. Resetting it back however disables both of them again.


Also tried: creating a file called config inside /etc/pm/config.d/ and giving it executable permission (chmod +x). Also tried putting the file inside /etc/pm/sleep.d.

user@computer:~$

cat /etc/pm/config.d/config
SUSPEND_MODULES="wl0,rt2800usb"

But none of these helped so far.. How can I get around this issue?

If the cheap Chinese USB works better, why do you need the internal Broadcom to work at all? Why not simply blacklist wl?

The cheap Chinese USB wifi is kind of huge and not practically portable.. So when I move around with my laptop I still need my built-in wifi and the ubuntu suspend functionality. Initially, I wanted to hibernate but since Linux can't deal with Secure Boot and hibernation I just settled for suspend, which also turns out to be problematic. What good is a laptop nowadays with not sleep and hibernation functionalities? This is why I want to take the hard road and fix the issue rather than just opting back into windows.
