[Solved] Wifi not working after installation
I just installed Mint Sonya and my wifi is not working.
I'm a newbie in Linux so i search something on Forums, without success.
rfkill list all says :
2: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
The driver is Broadcom Corporation: BCM4313 802.11bgn wireless network adapter
Can someone know the problem? Thank you in advance

Re: Wifi not working after installation
Do you have the proper Broadcom driver installed? For more information, see the "Broadcom chipset: install the driver" section of the "How to solve internet connection problems" article from the Easy Linux Tips Project.daveoid92 wrote:Broadcom Corporation: BCM4313 802.11bgn wireless network adapter

Re: Wifi not working after installation
Recently enjoyed my first broadcom adventure on gnu/Linux. Had seen many people say it can be a real PITA and yep, for me it was. Believe tried playing with a recent live session of Mint, wasn't the latest but newish and nope my wireless wouldn't work either.
First off would make sure it's enabled and not disabled in the systems bios/uefi-firmware and by hitting any key combo which would ordinarily do that. ie: On my system I can disable/enable wireless by hitting the Fn = function key + F2. Doesn't work ...
Try ( and I'd have had it sorted out in 10mins if I'd had this available.) plugging in your hard wired internet connection cable. That should get you connected even if wireless isn't working. Then check the Mint updater thingy (or software center thingy) for the Install Additional Software/drivers thing. Can't remember exactly how it's laid out and have nothing Minty onboard atm. Might find the proprietary broadcom drivers to get your wireless working offered in it.
Way I had to go about it, due to only having wireless as the only means of connectivity. I used a distro which detected/supported my broadcom wireless out-of-box. Bunsenlabs Linux the Hydrogen release did so no problem. Chrooted the problem install from live-session with it. See that by way of a good resource on the topic. Then I had to install dkms, broadcom-sta-dkms and the linux-headers for the version of the kernel I was using. To get it to build and correctly install the missing proprietary drivers I needed to get wireless working.
So if your hardwired connection is working, install those packages and see if wireless is now going strong doing this with the system cabled into the internet. So you won't have to bother with chroot from live-session etc. What broadcom packages are installed on your OS ? Output of "dpkg -l |grep broadcom" being one step to investigate that. Also see if dkms is already installed, very well could be.
This is a Debian Stretch netinstall, which added a bit of pains to getting it done. Also installed and briefly played with ubuntu 16.04 and after luckily deciding to hit the Fn + F2 key to check if wireless was even enabled on the system, wireless worked out-of-box in it. Though I don't like ubuntu, so quickly found the solution necessary to get it working in what I do like and overwrote buntu v 16.04.
Overall broadcom wireless turned out to be a bit of a pita but not too bad after looking into the topic and finding a fix.

now i'll try to reinstall the bcmwl driver now with that blacklist, and if it change nothing i'll remove it once more time!
If u have others ways to try, Thank you so much!!!
edit: ok nothing, i'll remove it once more! the blacklist.conf it's unchanged! ty but it still not finding the networks
maybe it's of some use the iwconfig ?

Uninstall/purge bcmwl-kernel-source, then see the wireless script link in my signature and post results. What model computer is this?

Copy the contents of the wireless-info.txt and paste between code tags
You might want to check your router settings and make sure it is on channel 1-11 as Broadcom cards don't work on 12-14 in Linux

Re: Wifi not working after installation
I would definitely change it as the wifi card is working, it just can't find any networks
Re: Wifi not working after installation
That really depends on the wifi router on how to change the channel, most have a web interface
