I am using Debian on a 2014 Macbook pro. I installed the broadcom wireless drivers from the official debian wiki.

Every now and again I get this error where my laptop disconnects from the wifi and then won't reconnect.

Here's my dmesg log

I am not sure how to fix this, what could be done to solve this issue?

Seems like it is happening after suspend/hibernate for most people? I haven't found a definite answer, but this might get you closer:

What is the additional phy0 or PHY in general?

Looks like it is probably something similar.

My wifi card stops working if I suspend and then resume, and I had to write a little script in /etc/pm/sleep.d/ that removes the wl module and then reloads it. Hope this helps you in some way!

** EDIT **

Your system is reporting the card model as:

[5.372637] wlan0: Broadcom BCM43a0 802.11 Hybrid Wireless Controller 6.30.223.248 (r487574)

Apparently the 'wl' driver you are using is prone to these random errors. I have found someone else with the same Broadcom make that solved the problem by uninstalling the 'wl' driver and installing the one downloaded from Broadcom directly: (page is in French, translated to English)

https://translate.google.ca/translate?hl=en&sl=fr&u=http://www.hilpers.fr/1361762-machine-mi-figee-avec-driver&prev=search

Good luck, let me know if that works.

  • I set my laptop never to go to sleep or anything like that. Even just leaving it on it will just drop out in the middle of streaming of a video on YT or something. I try to avoid manually compiling drivers so that I don't make frakendebian but I just might need to give this a shot. I'll accept this answer and hopefully won't have to make a new question in the future. – user1610950 Nov 20 '15 at 6:44

Power management may be the issue. Have you tried the solution offered at the Wiki you reference in you question: iwconfig wlan0 power off?
