Step-by-step – Realtek RTL8188CE Driver Ubuntu 21.04 Installation

GNU/Linux Ubuntu 21.04 Realtek RTL8188CE Driver Source Setup – Step-by-step Guide

Hi! The Tutorial shows you Step-by-Step How to Install Realtek RTL8188CE WiFi/Bluetooth Wireless Driver from Source Code in Ubuntu 21.04 Hirsute GNU/Linux.

And this Realtek RTL8188CE Driver for Ubuntu 21.04 Fixes some well known Issues and so:

• It has been modified to allow you to transmit at up to 33 dBm instead of the stock driver hard limit of 20 dBm, regardless of your CRDA regulatory domain. This is a substantial increase in capability because every 3 dB increase is equivalent to a doubling of the power. IOW, you can pump out 4x more Tx power than before. This is subject to CRDA restrictions however (though you can set that to whatever you want, just make sure you’re staying legal)
• It has a few default settings that generally increase stability
• Some helpful fixes are backported from newer kernels so that they can be enjoyed without upgrading the entire kernel (very useful for staying on your distros current kernel while benefitting from fixes relating to this driver)

Again this Driver may be functioning also for all the following Realtek Chipsets:

• RTL8188CE/RTL8188EE
• RTL8191SE
• RTL8192CE/RTL8192DE/RTL8192SE
• RTL8723AE

As suggested from the Realtek Driver Support.

Especially relant: please be aware of how this Driver is Not supporting all the Linux Kernels range, so in case of issue consult the available Online Documentation.

Finally, this Realtek RTL8188CE Driver Ubuntu 21.04 Setup should be working also after a Kernel Upgrade with the Dkms integration.
