WiFi vanished, HP 250 G8 Notebook

Hello,

I have a HP 250 G8 Notebook and everything was working pretty fine and i really like what Zorin looks but it has no cable ethernet onboard!
After I installed & configured Zorin like I need it some days later my WiFi connection diappeared; no conection and no optipn for WiFi in the systemtray menu.
Also no Wifi in Settings/Network.
I cannot use "systemctrl restart NetworḱManager" as it has no effect.

The same happened before and I had to reinstall Zorin with all software I need.

I want to avoid to have to reinstall Zorin and install all my Software again just because the WiFi doesnt work.

I searched several forum threads here and on other forums, but none made me succeed to get that solved.

Can anybody please help me on reactivating my WiFi connection?

Thanks a lot,
rfnX

Can you please post the terminal output of

sudo lshw -C network

Thank you !

This shows as Ethernet built in with the driver:

Does nothing happen when you connect the internet cable?

With your computer connected using Phone hotspot or with ethernet, can you run the following in terminal:

sudo apt install rtl8821ce-dkms

My notebook doesnt have a RJ45 plug.
My Mobile is an old Xperia F3311 and the Sony HowTo doenst make the USB tethering work nor Bluetooth Tethering is finding my mobile.

Can I transfer by USB?
What do I need to get installed?

BTW
Everything has been workin great and then the WiFi vanished after I started my NB on the next day

I tried the folowing

Downloaded rtl8821ce-dkms as deb for Focal and tried to install it by dpkg -i
(Ubuntu – Paket-Download-Auswahl -- rtl8821ce-dkms_5.5.2.1-0ubuntu3_all.deb)

result:
sudo dpkg -i rtl8821ce-dkms_5.5.2.1-0ubuntu3_all.deb

sudo dpkg -i rtl8821ce-dkms_5.5.2.1-0ubuntu3_all.deb

I don't think I did anything wrong, did I?

This is my Zorin Version (16.3):
cat /proc/version

Linux version 5.15.0-78-generic (buildd@lcy02-amd64-027) (gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #85~20.04.1-Ubuntu SMP Mon Jul 17 09:42:39 UTC 2023

Thanks for your help

also tried another version I found over the Zorin Forum:

https://ubuntu.pkgs.org/22.04/ubuntu-proposed-universe-amd64/rtl8821ce-dkms_5.5.2.1-0ubuntu11~0.22.04.3_all.deb.html

This one opened with the Zorin Software Manager, but it stated that it's already installed:

I still don't have WiFi.

Appreciate your help, thanks

When nobody here can help me with reactivating my WiFi I would appreciate if I would get a solution to avoid the "WiFi vanish" Issue when I install Zorin next time!
Otherwise I will have to use another distro and install the needed Gnome Extensions myself to make it look like Windows!

Zorin is giving me a quiet good usability as former MS user but it seems that Zorin is still a bit buggy.
On my HP desktop I have no problem, but here I have Cable Ethernet.

Thanks!

Not easily, as I suspect you will need to also download extra dependencies.

Have you tried booting into an earlier kernel?

At boot, enter the grub menu, then choose Advanced Options for Zorin and select booting up Zorin On 5.15.0-76 or earlier.
If it works, we can lock your kernel to the working version.

Thanks for the answer!

I tried to make the grub menu visible by editing /etc/default/grub and changing GRUB_TIMEOUT_STYLE=hidden to: GRUB_TIMEOUT_STYLE=menu but the grub menu does not show.

How can I use another Kernel / make the Grub menu showing?

After doing this, did you run sudo update-grub
?

You can also try to make it appear by tapping the esc or tab key at boot when you see the motherboard splash screen if using EFI boot.
For Legacy (MBR) boot, hold the Left Shift Key down during boot.

Have you tried booting into an earlier kernel?

Yes I made the sudo update-grub but it keeps black showing the Zorin Z splash & goin on with boot.

At boot, enter the grub menu, then choose Advanced Options for Zorin and select booting up Zorin On 5.15.0-76 or earlier.
If it works, we can lock your kernel to the working version.

OK, I booted with Kernel 5.15.0-76 instead of 5.15.0-78 but the issue stays

The install disk, I believe, uses the 5.15.0-56 , not the -76 or -78...
You said it was working fine at install.

Try the -56 kernel?

My Grub is only showing
5.15.0-56
5.15.0-56 (recovery mode)
5.15.0-58
5.15.0-58 (recovery mode)

I just (re)installed 1 one or two weeks ago ...

Yep, this one.

5.15.0-56 is also nt making th WiFi work.
I used the recovery mode for the _78 Kernel and did a dpkg repair

No effect

Tried a "lspci" but it does only show

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)

But no WiFi Adapter.

I'm not really a pro in linux but doesnt that mean that the WiFi Adapter is not present or broken?
How can I check that?

I bought that notbook about a yaear ago.

This is your wifi card.
Which should work with:

The Ethernet shows as functional with the correct driver. Did you say you do not have a cat5 port? Or lack the cat5 cable?

No that Notebook (HP 250 G8) has no Cat5 cable- or RJ45 plug ...

sudo apt install rtl8821ce-dkms

Would love to be able to do that but without any online connection that wont work :wink:

But lspci shows also the WiFi Adapter. I must have missed it ...

Just Zorin does not show it :wink:

BTW rtl8821ce-dkms is installed;)

Don't have any clue what's goin on here!
Like I told the same happened with my last Zorin installation :wink:
