[SOLVED] Wifi trouble after reboot with wifi off

Hi,

Here is my problem, last night i shutdown my computer with wifi turn off, and this morning, i can't get the wifi to work.
Its probably related to that, or probably to my last update.
Here is some commands that may help you :

I hope i do not forget anything that may help you. If so, just ask i will add the commands output.
Thanks.

Ps : Btw i've tried to disable tlp but that's seams that not the problem.
And tried to reboot 3 - 4 times too

Re: [SOLVED] Wifi trouble after reboot with wifi off

From reading the title, I thought this could be much worse.  But the only problem is an rf-kill softblock.  You should be able to `rfkill unblock all` and you may be set.

Re: [SOLVED] Wifi trouble after reboot with wifi off

There is only a soft block on the bluetooth, and none on the wireless hmm

Btw i can't see my wifi neither in param configuration, not in panel

Re: [SOLVED] Wifi trouble after reboot with wifi off

Oops!  Sorry, I misread.

Looking more closely, it seems you do not have a driver for your card.  I believe that card is only supported by wl.  If you installed wl from the AUR, you may need to rebuild it if there was a kernel (or other dependency) upgrade.

What driver were you previously using?

Re: [SOLVED] Wifi trouble after reboot with wifi off

It seams that i was using "broadcom-wl-dkms
Cause i've tried to install "broadcom-wl" from AUR right now and here is the output :

chargement des paquets...
résolution des dépendances...
recherche des conflits entre paquets...
:: broadcom-wl et broadcom-wl-dkms sont en conflit. Supprimer broadcom-wl-dkms ? [o/N]

There is a conflict between both.

Edit : So i've installed the "broadcom-wl' and remove the "broadcom-wl-dkms" and reboot .. and Voila big_smile Wifi is back !
Thanks !!
Edit bis : "If you are using broadcom-wlAUR, uninstall and reinstall it after upgrading your kernel. "
According to https://wiki.archlinux.org/index.php/broadcom_wireless.
So seams to be the same for the "dkms" version. (well i'll tried to remember for the next kernel udapte)

Re: [SOLVED] Wifi trouble after reboot with wifi off

I believe dkms are supposed to "rebuild" themselves with kernel upgrades to avoid just this sort of situation.  Perhaps something went wrong.  Or perhaps dkms isn't quite what I thought: I don't have any first hand experience.
