Summary0015948: WLAN Hardware not detected RTL8822
DescriptionHello,

WLAN on Notebook HP EliteBook 840 G5 would be not detected (RTL8822BE 802.11a/b/g/n/ac WiFi adapter) on CentoOS7 (with latest update 2019-03-23).

In other distribution (ElementaryOS 5.0 Juno - based on ubuntu bionic) the WLAN works properly.

I will append two files with some diagnostic data from both distributions (CentOS7 and ElementaryOS).

Thank you very much ...
Swen

Your device most likely uses the r8822be driver. This is not part of the CentOS kernel. I suggest you try one of the support venues instead of the bug tracker to get help.

You may want to do a test install of ELRepo's kernel-ml which has this driver enabled.

Or try kernel 4.19 available from CentOS:
