Realtek RTL8192CE Driver CentOS 9 Installation – Step-by-step

GNU/Linux CentOS 9 Stream Realtek RTL8192CE Driver Source Setup – Step-by-step Guide

Hi! The Tutorial shows you Step-by-Step How to Install Realtek RTL8192CE WiFi/Bluetooth Wireless Driver from Source Code in CentOS 9 Stream GNU/Linux.

And this Realtek rtl8192CE Driver in CentOS 9 Fixes some well known Issues and so:

• It has been modified to allow you to transmit at up to 9 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.

Again this Realtek RTL8192CE Driver CentOS 9 Stream Setup should be working also after a Kernel Upgrade with the Dkms integration.

Finally, this Setup is Valid also for All the others Red Hat Linux Based Distros like:

• Red Hat Enterprise Linux
• Oracle Enterprise Linux
• Rocky Linux
• AlmaLinux
