Fixing Slow Wifi Realtek rtl8821ce in Newest Linux Kernel

Wifi card is a small component in your laptop you can't choose. Lucky if you get a common, fine working wifi card with Linux kernel.

Recently I got a laptop with Realtek rtl8821ce that has a serious issue with newest Linux kernel (5.11.x and above). The wifi card becomes so slow after I did a system upgrade.

Apparently, the issue is caused by inappropriate driver loaded by the newest Linux kernel that makes the wifi card works less than a decent performance we should get.

The solution is quite simple. You have to install the appropriate driver from Ubuntu's official repository:

  1. Connect to internet using your Android's USB thethering connection.
  2. Install this following package:
    sudo apt install rtl8821ce-dkms
  3. Reboot your system

Mr. Namaku,

This is kind of the problem I had with Ubuntu 21.10 and my Realtek 8811 wifi dongle. It caused me to go back to good old Linux Mint. Does this solution also apply to my WiFi dongle?

It should fix your problem too.

Good news is, this issue seems gone on Ubuntu 22.04. Try update to latest 22.04 and see what happens.

Q4OS 4.6 "Gemini" Review: A Real Hidden Gem

Distro hopping is a fun adventure. It's a pure joy you can only find in GNU/Linux world. It's a nature you want to escape from what I call 'comfort ecosystem'. You need to play, trying something new even for a few little differences. For a long time I've been using Ubuntu family as my daily driver. The main reason is probably just same as any other Ubuntu user: it's reliable. You can't go wrong with Ubuntu. It works almost in any device, even for the newest one. It is the ultimate Linux distro you can rely on. However, sometimes, you will feel bored. The temptation to flirt with other new distro is unbearable. There are a lot of hot new Linux distros waiting to try.  A Real Hidden Gem I've known this distro for a quite long time. At first, it offered Trinity Desktop as the main desktop, which brings me the sweet memories about KDE3. It is simply fast, stable, almost without any issue, and it is based on Debian. I install it on my old machine and I love t...

Download, Install and Play Angry Birds Rio In Ubuntu/Debian Linux

Angry Birds Rio is a spin-off of the new-legendary game Angry Birds. This plot is specially taken from popular animation film Rio, an adventure of a pet Blue macaw bird from US in Brazilian jungle. Based on that successful film, there are some game developers created a spin-off for Angry Birds game called Angry Birds Rio. The good news about this is, there is already a flash version of this game so we could play it in Linux desktop easily using flashplayer (standalone player, or by Internet Browser with flashplayer plugin). And just like what I've done before in Angry Animals game, I've packed this game too into Debian package so we could install it with ease. If you have had installed flashplayer standalone, you don't have to download and install it. But, if you haven't it yet, you have to download the flashplayer standalone to play this game. These are the packages : adobe-flashplayer-standalone-linux_10_i386_debian.deb angrybirds-rio_0.1_i386_debian.deb This is a fre...
