No wifi interface after upgrading from Leap 15.1 to 15.2

English Network/Internet
#1

Hello, happy new year forum!

I have a lenovo Y510P that had been running Leap 15.1. After I did the upgrade to Leap 15.2, I noticed that no wifi scan was availble in the networkmanager (KDE) anymore.

Command “ip link” showed no wireless interface either. “lspci” shows a "broadcom BCM43142 802.11b/g/n (rev 01).

That said, if I boot to the old kernel 4.12, wifi works fine just like before.

Package “boradcom-wl” from packman repo has always been in the system. I tried to install some other wl packages but it didn’t help.

You need to have the matching (running) kernel ‘broadcom-wl-kmp-default’ package installed as well.

#3

OK. I do see that I only have the version 6.30…k4.12…package installed.

How am I supposed to install the k5.3 version then?

#4

Do you have the packman repo configured? Is it the correct repo for Leap 15.2, or is it still the 15.1 repo? Check the repo url. The broadcom-wl drivers are there.

#5

Sorry, I’m stupid !! I forgot to change the url of packman to 15.2…:shame:

#6

That’s an easy mistake to make. Hopefully things are now working as they should.

#7

But after I installed the broadcom-wl-kmp-default k5.3 version I still have no wifi available.

The wl interface is still missing.

Tried uninstall-reinstall all the wl packages without any improvement.

What’s worse, the k4.12 version has been replaced by the k5.3 version and I don’t even have wifi with kernel 4.12. :frowning:

Do you have wired ethernet connectivity available?

Yeah I do have wired connection.

Don’t know what’s the number in “lp152.14 or lp152.57” if those matter.

The kernel package looks to be ok for your running kernel.

Check if there is a driver loaded

/sbin/lspci -nnk | grep -iA3 net

I marked the Version-Release in bold:
broadcom-wl-6.30.223.271-pm152.14.12.x86_64

k = kernel
lp152 = Leap 15.2
pm = Packman

If the module wl is not loaded as deano_ferrari mentioned, install the kernel package once more:

zypper in -f broadcom-wl-kmp-default

and run:

dracut -f

Both as root with

su -l

Many thanks!

I will not be near the machine for a few days but I’ll try those commands when I am and report back.

#14

Hello, this is the output of your suggested command. My understanding is that wifi driver is not loaded?

# /sbin/lspci -nnk | grep -iA3 net
07:00.0 Ethernet controller [0200]: Qualcomm Atheros QCA8171 Gigabit Ethernet [1969:10a1] (rev 10)
        Subsystem: Lenovo Device [17aa:3800]
        Kernel driver in use: alx
        Kernel modules: alx
08:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n [14e4:4365] (rev 01)
        Subsystem: Lenovo Device [17aa:0611]
        Kernel modules: wl

So then I did


zypper in -f broadcom-wl-kmp-default
dracut -f

and reboot.

Wifi scan is still not available. I ran

# /sbin/lspci -nnk | grep -iA3 net

again and the result is the same as above.

#15

That shows that the wl driver is loaded.

#16

Any suggestion on where else to look at?

ip link
#18

Hello, I can’t always login the forum on that laptop so I am posting from the other machine now.

My ‘ip link’ has only the following 3 entries:

  1. lo
  2. eth
  3. teredo (yes I use teredo for some ipv6 access).

So the wl entry is missing I guess?
I tried using the “wicked” service and it couldn’t find any wireless connection.
I tried the hotkey for “flight mode” on/off and it didn’t seem to work either.

It’s strange because when I had access to the 4.12 kernel boot entry wifi works fine there. BTW now I don’t even have a boot entry for 4.12 kernel any more after some system update.

#19

I finally found out the problem after more research on the internet.

I had to disable secure boot to get the wifi to work. So its driver is not signed.

I have never had a similar problem with opensuse although I have always enabled secure boot on opensuse machines.

Why is that this particular driver is not automatically signed by opensuse? Can I make it work with secure boot enabled now?
