[Solved] Broadcom wifi not detected

I have a Broadcom BCM43142 on my HP Pavilion p077tx.  I have i3wm installed. My wifi card isn't detected.

Here's the output of `dmesg` :   https://ptpb.pw/85Rn
And the output of  `lspci -k`     :   https://ptpb.pw/JV-m

`lspci -k` doesn't show any Broadcom wireless card. I tried installing broadcom-wl and then removing broadcom-wl and installing b43-firmware from AUR but it didn't change anything. Currently, I have `b43-firmware` installed.

Re: [Solved] Broadcom wifi not detected

try installing broadcom-wl or broadcom-wl-dkms(recommended) for Broadcom BCM43142.

For lack of exactly output, please poste the result according to the following wiki pages:

Archwiki/Broadcom_wireless#broadcom-wl wrote:

Device with broadcom-wl driver not working/showing
Be sure the correct modules are blacklisted and occasionally it may be necessary to blacklist the brcm80211 drivers if accidentally detected before the wl driver is loaded. Furthermore, update the modules dependencies depmod -a, verify the wireless interface with ip addr, kernel upgrades will require an upgrade of the non-DKMS package.

@royalharsh95, from your output , the 'broadcom-wl-dkms' didn't drived.
  Reading the references, there are almost the same problems about you.

Re: [Solved] Broadcom wifi not detected

Unfortunately I'm not exactly sure how to approach this, but if the device doesn't show up in lspci output, then drivers are irrelevant.  Don't bother with trying to find the right driver until the absence of the card in lspci is sorted.

Are you sure it's a pci interface?  Does the card show up in lsusb?

Re: [Solved] Broadcom wifi not detected

Does the notebook have a WiFi key (often somewhere on the keyboard, typically behind some "Fn" modifier)?
Any changes by pressing it?

Re: [Solved] Broadcom wifi not detected

That is also not relevant.  Again, if the hardware isn't detected, tinkering with drivers (or rkfill settings) is irrelevant.

Re: [Solved] Broadcom wifi not detected

Sorry for posting twice. But my issue got resolved. Don't know how. I tried switching my internal network adapter off and then switched it back on from BIOS and then rebooted.
Here's the current output :
- sudo lspci -vnn -d 14e4:

Believe it or not, but some of those keys operate the HW directly and cut the power from the chip.

Re: [Solved] Broadcom wifi not detected

Yes, seth, that's an rfkill hardblock.  But it doesn't make the hardware physically disappear.  It is still listed in lspci/lsusb.
