Thank you for your help.
I have tried backing the kernel to 5.10.89-1,
adding my wifi network to the network settings.
downloading the BCM43142 firmware from AUR.
I’m at home trying to connect to my home wifi network. There are other devices connected to the network.
~ nmcli g
STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN
connected full enabled enabled enabled enabled
~ nmcli r
WIFI-HW WIFI WWAN-HW WWAN
enabled enabled enabled enabled
Thanks for your help, I appreciate it because I know this is a common problem and you guys probably get tired of people asking.
Thank you, BluishHumility for your help. Unfortunately, I have to get to sleep, so I will need to continue this tomorrow. Again, thank you for taking the time. If you think of any ideas, please let me know.
pamac install linux510-broadcom-wl
substitute to install appropriate kernel version, e.g linux515-broadcom-wl
install appropriate linux headers as well for good measure
pamac install linux510-headers or linux515-headers as appropriate
However, remember that his option isn’t dkms so definitely won’t survive ALL updates. It might some, I’m not on that, but it won’t all. Especially involving your kernel. So you might need to rebuild the driver after updates, and definitely when changing kernel versions.
My experience with these (linux515-broadcom-wl) on two older computers, is that when they update the kernel these are automatically updated whether on Stable Branch or any other branch that I have used. They are in the official repositories (extra).
That’s excellent! As I mentioned, it would probably survive some updates, but not all.
For example, I think it might survive an update from kernel 5 version 5.13 to version 5.16, but I highly doubt a driver installed for, let’s say, version 4.14 will be good with an upgrade to kernel version 5.4. Or even 4.19.
