Last night, several packages were updated on my ThinkPad E520. Today, I see I no longer have a network manager nor WiFi.  Was there a package that might have caused this?  Any idea on how I can restore network manager?

tnx jk

BTW, WiFi still works in Windows 10, so it's not a hardware issue.

rpm -qa --last | grep <date of update> | sort

will provide you with the updated packages that you might determine which affected your networking.

Had the same issue recently, turned out to be an issue with Windows 10 fast boot. I turned off fast startup and my Wi-Fi was back in openSuse.

Fast boot isn't enabled.  I turned it off years ago for other reasons. Also, I made a mistake.  Network manager is there, but WiFi isn't listed.  There should be several connections listed, as there is for Ethernet.  If I go into settings, I can see the WiFi connections.

So, it's just WiFi connections are not listed and WiFi does not automatically connect when there is no Ethernet connection and I can't connect manually.

Not sure if I follow correctly, but if you can see the wifi connections listed in KDE System Settings > Connections, and they're not showing up in the Network Manager system tray popup, might it be just that you've unticked the wireless box within that popup? And for the same reason, wifi wouldn't connect automatically if there's no ethernet. gumb

Where is that button?  I don't recall seeing it and don't see it now.

I think if you're not seeing it there must be something else amiss. When you click the standard 'Networks' popup in the system tray, underneath the word 'Networks' at the top of the popup I have a check box with a wifi symbol next to it. Next to that there's another one for airplane mode, and then a Hotspot button. All on Leap 15.4. Otherwise, in the list of wifi connections in System Settings, if you click on one, then look under the 'Wi-Fi' tab on the right pane, you don't by any chance have the Visibility check box ticked, making it a hidden network? Obviously you wouldn't have done that deliberately but maybe the config has somehow become corrupted.

I think we may be heading in the wrong direction with Network Manager.  As I mentioned in another note, the WiFi NIC doesn't even show up with ifconfig or ip commands, though it does if I boot a rescue system.

That really reads like a missing driver; can you verify what driver is in use for the card when you boot a rescue system and ensure the non-rescue system has the same driver available and loaded?

I was working w/ a new RTL8852au adapter last night and was sad to see NOTHING displayed for it via `ip a` until I google searched a few things based off the model name and happened upon Larry's work for that driver. Now things are working as they should after a few commands 👍️

It's a Realtek RTL8188CE.  One thing I just noticed, under Drivers, "Active No" & "modprobe Yes".

I just tried this:

# lsmod|grep realtek realtek                36864  1 libphy                159744  3 r8169,mdio_devres,realtek

It shows the Ethernet NIC, but not WiFi.

I'm not sure that's the best method, which isn't your fault - it seems like driver names are only _known_ once you already know them. I'd suggest something like: `inix --network` or `inxi --network-advanced`. In my case it reports as rtl8852au but lsmod is valid for 8852au ; same goes for modinfo. Frustrating that you basically need to know the answer to find the answer 😑️. So if you can verify the driver in use under rescue, maybe you can probe the system to find out why it's not being loaded outside of rescue. I can't guarantee this is [any part of] your issue, but the fact that no device is even listed reeks of a missing/unloaded driver. -- ~ Scott Bradnick |- Windows Subsystem for Linux (WSL) Developer |-- Tumbleweed: |--- Dell Precision 5540 [NVIDIA Quadro T1000] (x86_64) |--- O-DROID H2+ [UHD Graphics 600] (x86_64) |--- IceWhale ZimaBoard 832 [Intel HD Graphics 500] (x86_64) |--- 2x Raspberry Pi 4 Model B Rev 1.2 (aarch64) |--- 1x Raspberry Pi 3 Model B Rev 1.2 (aarch64) |--- WinBook TW100 (x86_64) https://keys.openpgp.org/ :: DBC5AA9A2D2BAEBC

That lsmod command should have included both network drivers, but only Ethernet appeared.

You can try that inxi command under the rescue system to find out the exact name of the wifi driver. The xfce rescue image, when installed on an USB stick, is r/w and you can install inxi on it if it is not already there. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)

I've been using the rescue system from the install USB stick.  Inxi is not on it.

The following will enable inxi use if the wired connection is up and DNS is working: md /usr/local/bin && cd /usr/local/bin && wget -O inxi smxi.org/inxi && chmod +x inxi https://smxi.org/docs/inxi-installation.htm#inxi-manual-install --no-check-certificate may needed as another wget option.

I have a 15.0 rescue USB stick and added inxi to it.  It shows the Wifi driver as rtl8192ce

I was thinking about something like that, but would prefer to know what the problem is and fix it. If I have to resort to it, I suppose I could use the autostart in Desktop settings.

There's a good chance the system already told you what to do 😉️

That did it, but something weird happened.  My desktop is dim.  As the computer boots, the brightness is normal, then it gets dim before the desktop starts, to the point of being almost unusable.

Maybe there is a way to allow unsupported for this module only. :-? Yes. Try a file like: /etc/modprobe.d/10-my-unsupported-modules.conf: options rtl8192ce allow_unsupported=1

I wonder what changed to require adding that file.

Ask in Bugzilla. Some decision was taken to no longer support that module for some reason. Why this happened in the middle of Leap 15.4 life.

The first one appears to work fine.  As for the brightness, I had to use the keyboard buttons to bring it up again so all is fine.  It makes me wonder when that setting is set, as changing it didn't appear to affect the screens before login and didn't affect Windows either.

Then remember to use only: options rtl8192ce allow_unsupported=1 and delete the generic line: allow_unsupported_modules 1 -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)

When I run dmesg and grep on the driver name, I get this for the Ethernet driver:

There doesn't appear to be anything related.

Can you run: `sudo modinfo rtl8192ce` or `sudo modprobe rtl8192ce` and get any positive results? My system (which is TW), doesn't use that particular driver, but has: /usr/lib/modules/$(uname - r)/kernel/drivers/net/wireless/realtek/rtlwifi/rtl8192ce/rtl8192ce.ko.zst So it should come from the kernel-default package; maybe there was some type of hiccup on an update? I do have to run `sudo depmod -a $(uname -r)` [initially] when I build the 8852au driver before the kernel will load it in. -- ~ Scott Bradnick |- Windows Subsystem for Linux (WSL) Developer |-- Tumbleweed: |--- Dell Precision 5540 [NVIDIA Quadro T1000] (x86_64) |--- O-DROID H2+ [UHD Graphics 600] (x86_64) |--- IceWhale ZimaBoard 832 [Intel HD Graphics 500] (x86_64) |--- 2x Raspberry Pi 4 Model B Rev 1.2 (aarch64) |--- 1x Raspberry Pi 3 Model B Rev 1.2 (aarch64) |--- WinBook TW100 (x86_64) https://keys.openpgp.org/ :: DBC5AA9A2D2BAEBC

Also ifconfig and ip don't list the WiFi NIC.

Booting into a 15.4 rescue shows the WiFi NIC, so it's something on the installed 15.4.
