Without fail, I boot into Ubuntu and everything is working, but after closing the laptop the wifi stops working. When I restart everything works again.

Running iwconfig, before restarting, gives me this:

wlan0 IEEE 802.11abg ESSID:off/any
Mode:Managed Access Point: Not-Associated
Retry long limit:7 RTS thr:off Fragment thr:off Power Management:on

I am very new to Ubuntu, so any help will be very appreciated!

Macbook Pro (Retina, mid 2014)

Wireless stops working after suspend, I think this is what you're looking for it's on this page: https://help.ubuntu.com/community/MacBookPro11-1/Saucy lot's of good info here.

create a file

  1. sudo nano /etc/pm/sleep.d/99_myfix

put the following into the file

  1. #!/bin/sh

    case "$1" in
resume|thaw)
        service network-manager stop
        rm /var/lib/NetworkManager/NetworkManager.state
        service network-manager start
        ;;
esac

and set its permission to 755

  1. sudo chmod 755 /etc/pm/sleep.d/99_myfix

  • Would this work on other computers too (Dell XPS)? I've been having this problem – Matt G Mar 28 '17 at 21:02
  • btw this still works for ubuntu 19 on a macbookpro 2015. – Eli Albért Nov 28 '20 at 12:25
  • actually this works for suspend, but if I leave my early 2015 macbook pro suspended for long enough it hibernates, and then I needed the fix here https://askubuntu.com/a/893823/456289 – Eli Albért Dec 01 '20 at 19:01

It might be an issue with your wifi firmware. Here's an answer to a similiar question that might help you:

Download the brcmfmac43602 firmware from the Linux firmware git repo

Copy it to /lib/firmware/brcm

Reboot and enjoy your WiFi.
