HP laptop no wifi (only wired)


Hello again.
As suggested (thanks @colorpurple21859) I am continuing my tale of woe in a separate thread.

I have an HP 14 Laptop that came with windows 10. I successfully installed Bodhi alongside Windows (so my windows-only wife can use it too). So the two partitions are roughly the same size, 64 GB. On the Windows side the wifi works fine. On Bodhi, I only have wired ethernet (which I'm using now). The output of >lspci is:

From lspci
Code:
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter
The first thing to do is grab a recent kernel source and get looking [ device drivers/networking device support/wireless lan/ Realtek and the various drivers. I have 5.4.30, and it's not supported, but the 8822 is in the last option, which is tantalizingly close.

Next option is to google for a driver, and follow the instructions. You often need a compiled kernel source, with the driver saved elsewhere.

Then there's also the question of firmware. Or your distro may have a driver.

Hi Stephan,

I made the mistake of using the first link. I ran these two:

sudo apt-get install --reinstall git dkms build-essential linux-headers-$(uname -r)
git clone https://github.com/tomaspinho/rtl8821ce


The next step is: cd rtl8821ce

Unfortunately there is no such directory. How do I back out all the garbage that was loaded before I try bachelor #2?

Did you do the git clone as user, not root? If you did, then there would most definitely be a rtl8821ce directory in your current directory as the git clone command creates it...

Code:
~$ git clone https://github.com/tomaspinho/rtl8821ce
Cloning into 'rtl8821ce'...
remote: Enumerating objects: 86, done.
remote: Counting objects: 100% (86/86), done.
remote: Compressing objects: 100% (65/65), done.

Receiving objects: 100% (1559/1559), 5.85 MiB | 1.67 MiB/s, done.
Resolving deltas: 100% (841/841), done.
~$ cd rtl8821ce
~/rtl8821ce$ ls
clean            dkms-remove.sh  halmac.mk    Makefile  README.md
core             Dockerfile      ifcfg-wlan0  os_dep    rtl8821c.mk
dkms.conf        get_sources.sh  include      PKGBUILD  runwpa
dkms-install.sh  hal             Kconfig      platform  wlan0dhcp
~/rtl8821ce$ chmod +x *.sh
Should work.... then
Code:
sudo ./dkms-install.sh
But, to answer your question, how to back out. The only thing you actually installed was git, I think the other things are already pre-installed (and didnt need to be reinstalled, but didnt hurt anything), so if you want you could
Code:
sudo apt remove git
but I'd keep it around for next time. And the other thing would be to remove the folder you cloned (that you can't find)
Code:
rm -rf ~/rtl8821ce
edit: correction, i dont think build-essentials is pre-installed, so you could remove that if you really want too

The folder definitely does NOT exist:

rashkin@rashkin-HP:~$ ls
Desktop Documents Downloads Music Pictures Public Templates Videos
Code:
rashkin@rashkin-HP:~$ ls -a
.              Desktop      .local                     Templates
..             .dmrc        Music                      .thumbnails
.bash_history  Documents    Pictures                   Videos
.bash_logout   Downloads    .pki                       .Xauthority
.bashrc        .e           .profile                   .xsession-errors
.cache         .elementary  Public                     .xsession-errors.old
.config        .gnupg       .sudo_as_admin_successful
rashkin@rashkin-HP:~$
furthermore it does exist anywhere: attached shot from filemanager search

What messages do you get when you run
Code:
git clone https://github.com/tomaspinho/rtl8821ce.git
You can also open a web browser put in the url and download the zip file and extract to your home folder.
