I've just installed Ubuntu studio 21.10 on a new Asus laptop. Its now dual Boot with W10. Wifi works as expected in W10 but not in ubuntu. Adapter is a Realtek RTL8821CE. Is shows up when I do sudo lspci but beyond that I'm lost in Terminal. Any help to get the correct drivers installed would be greatly appreciated

benm@Bens-asus:~$ lspci -nnk | grep 0280 -A3

Please edit your question to show the result of the terminal commands: `lspci -nnk | grep 0280 -A3` and also: `sudo dmesg | grep 8821`

I've pasted it in but it has changed the layout a bit

Kernel 5.14 and above seem to address this issue/bug.

Please try: `sudo modprobe -r rtw88_8821ce` and: `sudo modprobe rtw88_pci disable_aspm=1` and then: `sudo modprobe rtw88_8821ce` Is there any improvement? Reference: https://bugzilla.kernel.org/show_bug.cgi?id=210779

I have entered the code but it seemed to have no effect

I am currently updating to Kernal 5.14. I think.

i've just gone through the update process but it seems i'm only at 5.13!

Did you reboot? What does this tell us? `uname -r`

Rollem Neb

5/30/23, 6:12 PM

yes, rebooted. 5.13.0-27-lowlatency

i tried following this https://www.linuxcapable.com/how-to-install-or-upgrade-to-linux-kernel-5-14-on-debian-11-bullseye/#ftoc-heading-8 but get to a stage where it says E: Type ‘sudo’ is not known on line 59 in source list /etc/apt/sources.list E: The list of sources could not be read.

No. Do not follow a Debian guide. I have no doubt that it doesn't work. Please revert all changes.

Rollem Neb

5/30/23, 6:29 PM

maybe i should reinstall. I tried your guide and i still get the message about the source list. I have no idea how to revert the changes

You could reinstall in 15 minutes or meet me in chat and undo all of the incorrect steps, maybe, in a couple of hours. Which do you prefer?

thank you, i think i'll reinstall in the morning. i have no work to back up or anything so a nice clean install might be best. I will let you know how it goes. i love working with ubuntu, this is third laptop i've had ubuntu on but every time the wifi has been an problem. i don't really understand why such a fundamental thing is such an issue

I will propose what I believe to be a *proper* working solution for the wifi a bit later. See you tomorrow.

Rollem Neb

yes it worked! I reinstalled then did the steps you suggested and it worked! Thank you

In fact now that I've got working wifi, dropbox and scrcpy installed I hope I never have to go near the terminal again!

Please note the well-known bug report: https://bugzilla.kernel.org/show_bug.cgi?id=210779

rtw88_8821ce doesn't work [1] can't connect [2]

Let’s blacklist the native driver:

sudo -i
echo “blacklist rtw88_8821ce”  >>  /etc/modprobe.d/blacklist.conf
exit

Next, with a working internet connection by ethernet, tethering or whatever means possible, do:

sudo apt update
sudo apt install git dkms build-essential bc linux-headers-generic
git clone https://github.com/tomaspinho/rtl8821ce.git
cd rtl8821ce
sudo ./dkms-install.sh

Reboot, disable Secure Boot and your wireless should be working.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
