[SOLVED] BCM4352 (Asus PCE-AC56) WLAN gone after rebooting

jasonc3a · 01-05-2020, 09:24 PM

Hello. I'm using Pop!OS 18.04 and with Linux kernal 5.3.0-7625. It's a fairly recent re-install, but I have a problem now that I didn't have before. Previously all I had to do was install the bcmwl-kernel-source package and it would show my WLAN card immediately and consistently in network-manager. Now however, it went from showing it after I first rebooted to dissappearing after every reboot.
I'm not too sure what the problem is. If I enter

Code:

$ sudo modprobe -r ssb wl bcma
$ sudo modprobe wl

as suggested in various areas on the internet it shows up immediately. When I first got this card working with plain old Ubuntu 18.04 I remember having to muck around with mokutil in some way or another, but I can't seem to find any documentation I made on it, nor can I see any hint of the previous solution after much Googling (maybe it was a cobbled together answer.)
I edited /etc/modules and appended "wl" to the end of it but it didn't seem to do anything. Ssb and bcma are also already listed in some blacklist.conf files in /etc/modprobe.d/ while wl does not seem to be.
I included any terminal output I thought was directly relevent. Edit: this is output from after I performed the previously listed terminal lines, but with the wireless turned off in network-manager. Really just wondering how I can force the wl module to load on boot.

So it just sort of works now. Nothing changed, no changes seen in the .conf files (at least those that I know of that could effect this), nothing different from what I can see except for a couple of reboots. If anybody else ever has this problem and finds a solution, I would still be super-interested in knowing what you did to fix it.

drumguy1384 · 01-19-2020, 10:40 PM

I would be interested to know the answer to this as well. I've recently installed Pop! 19.10 on an older laptop and have the same issue.

$ sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
$ sudo modprobe wl

starts my wifi, but it will not survive a reboot. All of those other drivers are blacklisted in /etc/modprobe.d so I don't know why this works or why it doesn't happen automatically. Intestingly, bcma seems to still be loading despite being blacklisted. That might provide a clue.

jasonc3a · 01-19-2020, 11:03 PM

I noted that as well at a certain point during my troubleshooting but neglected to include it! I only remembered that once you brought it up! Well, I'm messing around on other computers with ZFS and Ubuntu and all sorts of nonsense like that. I'm sure I'll have the pleasure of messing about with this problem again very soon and I'll keep this in mind when I inevitably need to find/stumble into a solution.

drumguy1384 · 01-20-2020, 11:04 AM

I've also noticed that simply running

Code:

sudo modprobe -r bcma
sudo modprobe wl

doesn't work. Neither does

Code:

sudo modprobe -r wl
sudo modprobe wl

I have to kill both wl and bcma and restart wl. This is extremely frustrating.

jasonc3a · 01-20-2020, 01:01 PM

So where I found the terminal commands to make the wifi work was here. I had far fewer modules in mine because they were non-existant, so I trimmed it down to just the ones that were effecting me.
However, when I was searching for the exact site where I saw this suggested I founnd this one. At a certain point it is suggested to try

Code:

sudo systemctl stop NetworkManager
sudo rmmod b43 b43legacy ssb brcm80211 brcmfmac brcmsmac bcma 
sudo modprobe -r wl
sudo modprobe wl

I never actually tried using the rmmod command in any of my troubleshooting. Maybe that could work for you?
