Wi-fi Adaptor Not Found HP in Ubuntu 18.04.2 RTL8821CE

[jvanhaaften]

Hello,

I am unable to connect to wifi. I am using ubuntu 18.04.2 and an HP 17-by0205ng:

02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

kernal 4.18.14-041814-generic

I am aware that this is a common issue for some HPs using ubuntu and I have tried several different downloads. Does someone know why or have a solution for me?

Thanks!

ps here is what I have tried:

Hi

This is the standard method...

When troubleshooting wireless, it's important that your system is fully updated by opening a terminal, CTRL+ALT+T. Using a wired internet connection, please run:
Code:

sudo apt update
sudo apt dist-upgrade

and reboot if necessary.

If the issues persist, it is recommended that you install pastebinit, by running:
Code:

sudo apt install pastebinit

This will enable the wireless script to, upon your approval, upload the obtained data to pastebin, creating at the same time a link to it in your terminal, permitting you to paste it to a forum thread.

Once that's done, download and run the wireless info script, which will gather information to help diagnose your system. You can run it using this command:
Code:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \
./wireless-info

It will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz". If you prefer, you can post the file directly to pastebin yourself. Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.

If you aren't able to connect to the internet with the affected system, including via a wired connection, just navigate to this link and follow the instructions there on how to the run wireless script without an internet connection.

Thanks for the quick response. I am using a wired connection and ran:

sudo apt update
sudo apt dist-upgrade

then re-started the computer with no luck.

I then installed pastebinit and here are the results:

Hi

Line 32 lists a WiFi device.

So can you use WiFi only and try and ping127.0.0.1 and then your Default gateway.

Hopefully ifconfig will also show some details.

It may be a. Miss configuration.
