| Summary | 0000915: WiFi driver; RTL8723DE 802.11b/g/n PCIe Adapter | ||||
| Description | Please develop a wifi driver for a 10ec:d723 for Centos 7 or can you tell me which kernel already contains that driver? I am currently using kernel 5.1.4-1.el7.elrepo.x86_64 but will use any kernel that will free me from this wire! None of my neophyte attempts to get this adapter to turn on or find a driver have worked. | ||||
| Tags | No tags attached. | ||||
| Reported upstream | |||||
|
|
Please post the output return by the following command -- lspci -nn | grep -Ei 'wifi|wireless' |
|
|
Nothing is output. |
|
|
FYI; [root@localhost president]# uname -r 5.1.4-1.el7.elrepo.x86_64 [root@localhost president]# rpm -q kernel package kernel is not installed |
|
|
I have to break bad news. First, we do not offer driver packages for non-distro kernels such as kernel-ml. Second, the source code available for RTL8723DE does not build on EL7. There is a slight chance we can offer the driver for EL 8.0 (kernel 4.18). However there is no guarantee that the code still builds when the OS is updated to EL8.1. |
|
|
So what kernel should I install to get a driver package? Or, are you saying that I cannot use this laptop wirelessly under Centos? |
|
|
There is no kernel that has the driver for your Realtek device. Your best option is probably to get a USB adapter that works out of the box. |
|
|
Please show the full output returned by the following command -- lspci -nn Until we have the details of the hardware in a very precise way, it is impossible to know if any kernel will support the wireless subsystem of your laptop computer. |

Thank you for posting the output. The relevant line is last one shown -- 03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723DE 802.11b/g/n PCIe Adapter [10ec:d723] With sight of that, I now know that WiFi hardware is defined by [10ec:d723]. Checking for the vendor (0x10ec) and device (0xd723) identifiers in the upstream (kernel.org) kernel sources shows that the manufacturer has not even tried to have the driver code merged into the mainline kernel (staging) tree. That, unfortunately, means the WiFi subsystem is not supported via either kernel-lt or kernel-ml for RHEL7. Hence I can only echo toracat's response from reply 6329 -- "Your best option is probably to get a USB adapter that works out of the box." |

Based on this experience, should I avoid any particular wireless USB adapters? Thank you for your help. I should have saved myself days of frustration and come here first! |

It's often not easy researching Wifi adapters as often it's not easy to find information about the underlying chipset used. Often it's easier to go by recommendation of something that is known to work. For example, when I recently required a cheap USB wireless adapter I went with an Edimax EW-7811Un which is widely available for $10 or less: https://www.amazon.com/Edimax-EW-7811Un-150Mbps-Raspberry-Supports/dp/B003MTTJOY/ref=sr_1_1?ie=UTF8&qid=1512370979&sr=8-1&keywords=edimax+n150 The above adaptor is based on the Realtek RTL8188CUS chipset and uses the rtl8192cu kernel driver present in el7 so will work out of the box. |
