BCM94352HMB drops after sleep

**kosak2** · August 21st, 2017

I am a fully converted Linux user, all my laptops and custom builds run Linux. In this case, my Asus X550LDV with a Broadcom BCM94352HMB Combo BT runs smoothly.

But when I put it to sleep, the WiFi drops and can't connect to anything after resuming. The only solution is toggling airplane mode on and then back off. That makes it work.
Any way I could avoid this nuissance???

Running on Ubuntu GNOME 17.04 all up to date. Regards and thanks in advance!

Hi please COPY and paste..

Code:

echo 'SUSPEND_MODULES="wl"' | sudo tee -a /etc/pm/config.d/config

*Note the full echo command in single quotes ' ' and wl in double quotes "wl"
hence the suggestion to COPY and paste.
Thanks.

Thank for the suggestion, but it doesnt work unfortunately...

I get this:

Code:

joe@chochiJoey:~$ echo 'SUSPEND_MODULES="wl"' | sudo tee -a /etc/pm/config.d/config
tee: /etc/pm/config.d/config: No such file or directory
SUSPEND_MODULES="wl"

Hi please open a terminal then copy and paste..

Code:

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*

Boot and then verify the above command turned Power Management. off

Code:

*If..yes/off then test sleep/suspend.

Worked like a charm! It works 4/4 times, so I think your tip resolved the issue 100%

Code:

joe@chochiJoey:~$ sudo iwconfig
