#Realtek 8192cu driver linux install#
Then to install it: # dkms install 8192cu/1.11 Use dkms to add the driver as a module to the kernel tree: # dkms add. I ended up with a rtl8192cu-fixes directory in my current working directory. Starting with a fresh CentOS 7.6 minimum installation: # yum install ĭownloading the Linux wireless chipset driver: $ git clone https : ///pvaret/rtl8192cu-fixes.git Although it does say that it is for the “RTL8192CU” chipset, the difference in the name postfix are for the various WLAN standards. I ultimately chose this post to follow:, as it was the easiest to understand. While there were many versions and slight variations to each package’s instructions, they were not too far apart from each other.
#Realtek 8192cu driver linux drivers#
I checked the official Realtek website and could only find the Windows drivers, but I did discover several community maintained drivers for the RTL8192EU chipset. Step 2: Finding Linux Drivers for the Wireless Chipset Alternatively, I could use a USB ID repository like to find out that it was the “RTL8192EU 802.11b/g/n WLAN Adapter”. Usb 3-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3Ĭombining the idVendor and idProduct values and doing a quick Google search immediately returns a list of forum posts regarding “Realtek RTL8192EU” devices. Usb 3-4: New USB device found, idVendor=0bda, idProduct=818b I plugged the adapter into my CentOS machine and used dmesg to find out more from the kernel’s message buffer. Setting aside the AmazonBasics branding, I needed to know the make and model of the wireless chipset. The rest of this post documents my process and hopefully to help out anyone who is also encountering the same issue. These links ( link1, link2) explain that while the CentOS 7.6 kernel version is 3.10.0, Red Hat has backported large portions of the network stack from more recent 4.x kernels.
This is due to the ioctl_cfg80211.c file being incompatible with the 3.10.0-957 kernel version that CentOS 7.6 uses. It uses the RTL8192EU chipset and while the official Realtek drivers are only available for Windows, there are a bunch of community maintained Linux drivers around.Īfter attempting for approximately 12 hours, I have come to the understanding that unless the kernel is upgraded, or the existing wireless chipset driver files are updated (tried 6 different repos), it is not possible to compile and install it on CentOS 7.6. I bought an AmazonBasics branded Wi-Fi 11N USB Adapter and was keen to set it up with a vanilla minimal install CentOS 7.6. Tl dr: On a vanilla CentOS 7.6 installation, it is not possible to install the Realtek 8192EU driver due to kernel incompatibilities.
