BCM4313 Wi-Fi not working after upgrade to kernel 5.19.0.32

in flag

Problem same as this one:

RTL8821CE wifi fail after upgrading from 5.15.0-60 to 5.19.0-32

lspci
07:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTL8411 PCI Express Card Reader (rev 01)
07:00.2 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0a)
08:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4313 802.11bgn Wireless Network Adapter (rev 01)

I was advised to install Broadcom drivers, which I did using

sudo apt install firmware-b43-installer

The driver now shows in Software & Updates but I still don't see WiFi option after reboot.

BCM4313 802.11bgn Wireless Network Adapter [14e4:4727] (rev 01) requires b43 kernel module with firmware-b43-installer.

You have a wrong driver installed that blacklists the correct driver.

You can either select "Do not use the device" in the GUI or run

sudo apt purge bcmwl-kernel-source
sudo modprobe b43

to get the device working.

Really appreciate your patience with me. Thank you so much. It works now.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
