O.S. RUNNING SLOW SOMTIMZ ......SENSE SECURITY IS BEING INFILTRATED
I DO KNOW ALL PROGRAMS CAN BE HACKED.....A FEW BUGS ......UBUNTU KNOWS....
OTHER THAN THAT YHEEEE!!! HAAA!!!

[dkmc (dkmc000)]

CHANGES DONE IN WIFI CHANGE .....ALWAYS HAVE T0 LOOK
NO REASON FOR SETTINGS TO CHANGE..UNLESS????????

[Corrado (ccutti)]

Still without WiFi, how can I restart wifi service?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[arm-c (arickmcniel)]

I just ran updates on my laptop... got error message:

Error while applying changes
pk-client-error-quark: Error while installing package: installed bcmwl-kernel-source package post-installation script subprocess returned error exit status 10 (313)

I lost all of my wifi card in my MacBook Air.

RECOVERY: For those like me, recovery can be a challenge. I didn't see how to get back to a older kernel while working through rEFInd boot manager.... but what got me out of this issue was.

- Open Additional drivers (Super Menu, type 'Drivers' and select).
- After scan for "Proprietery Drivers in Use"... switch option to "do not use this device" and apply.
- Reboot and hopefully your Wifi is restored.

I then ran all updates (sudo apt update & sudo apt upgrade). I went back to additional drivers and tried reinstalling... got error... but it appears to have taken... even after reboot.

After upgrading the kernel to 5.8.0-34-generic the package bcmwl-kernel-source 6.30.223.271 stopped working. Tried reinstalling without success.
Logs match with the logs reported.

[Stephen Gornick (sgornick)]

I too lost Wi-Fi after doing apt upgrade, which brought the kernel to 5.8.0.34-generic. Same "ioremap_cache" reported as above.

I found that the package for the broadcom in my Macbook Pro should be using firmware-b43-installer, not the bcmwl-kernel-source package, according to the "BROADCOM WIRELESS TABLE (Updated Oct 29, 2020)" table in this AskUbuntu answer:
https://askubuntu.com/a/60395/157287

$ lspci -nn -d 14e4: |grep Network
03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4331 802.11a/b/g/n [14e4:4331] (rev 02)

When I look up 14e4:4331 under the Ubuntu 20.04+ column, it says, for package name: firmware-b43-installer / linux-firmware

So then I removed bcmwl-kernel-source:

$ sudo apt-get purge bcmwl-kernel-source

And then plugged in a USB Wi-Fi adapter and installed firmware-b43-installer (linux-firmware was already installed):

$ sudo apt install firmware-b43-installer

Rebooted, and was back in business! (albeit for 2.4 GHz only, not 5 GHz)

Unfortunately, I wasn't so lucky with an old Lenovo E431 that had the same issue ("ioremap_cache").

$ lspci -nn -d 14e4:

04:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n [14e4:4365] (rev 01)

Which, in that table shows also to use firmware-b43-installer. But that's unrelated to this bcmwl bug, so I'll not pursue that here.

[Stephen Gornick (sgornick)]

Ugh .. correction on that, sorry. When I look up [14e4:4365] (rev 01) in that table, it does show bcmwl-kernel-source as the package. So I'm also unable use Wi-Fi, where the "ioremap_cache" error when it tries to build bcmwl.

[Stephen Gornick (sgornick)]

Looks like, from bug #1872908, that there was a patch added in 6.30.223.271+bdcom-0ubuntu6.

But when I install bcmwl-kernel-source, it pulls 6.30.223.271+bdcom-0ubuntu5.

$ sudo apt list|grep bcmwl-kernel-source
bcmwl-kernel-source/focal,now 6.30.223.271+bdcom-0ubuntu5 amd64 [installed]

So is this bug a duplicate of bug #1872908?

[Mike (blackf8x)]

So I managed to find some time and decided to try out the following patch 6.30.223.271+bdcom-0ubuntu7 and that worked for me.
I'm writing this comment with my WiFi connection :woohoo:.

[GIovanni de Oliveira (giovannide0000)]

I fixed mineee

Use the following (one at a time)

sudo -i

apt install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms

modprobe -r b44 b43 b43legacy ssb brcmsmac bcma

modprobe wl

systemctl restart network-manager

Just like that, it works.

Needs to be one of those, tough (lspci | grep Network to check) :

Broadcom BCM4311 (PCI IDs 14e4:4311, 14e4:4312)

Broadcom BCM4312 (PCI ID 14e4:4315)

Broadcom BCM4313 (PCI ID 14e4:4727)

Broadcom BCM4321 (PCI IDs 14e4:4328, 14e4:4329, 14e4:432a)

Broadcom BCM4322 (PCI IDs 14e4:432b, 14e4:432c, 14e4:432d)

Broadcom BCM43224 (PCI IDs 14e4:0576, 14e4:4353)

Broadcom BCM43225 (PCI ID 14e4:4357)

Broadcom BCM43227 (PCI ID 14e4:4358)

Broadcom BCM43228 (PCI ID 14e4:4359)

Broadcom BCM43142 (PCI ID 14e4:4365)

Broadcom BCM4331 (PCI ID 14e4:4331)

Broadcom BCM4352 (PCI ID 14e4:43b1)

Broadcom BCM4360 (PCI IDs 14e4:43a0, 14e4:4360)

Ok. The best solution for this is posted here on ask ubuntu. The issue is with the LTS update, it did not include the updated bcmwl file when it switches the Kernel to the HWE version. This is the link to where I found the solution I used and it solves my problem.

I chose option one.
