Realtek RTL8822BE Driver

Post by Qwaddles » 2019/12/26 19:40:44

I have recently installed CentOS on a asus laptop. Installation went ok except I cannot see or connect to any wifi networks. I connected via ethernet and did a "sudo yum update" then rebooted which didn't seem to fix anything. I am assuming it is a driver issue, but I am having trouble finding any good information on how to fix it.

"nmcli device status" gets me:

Code: Select all

DEVICE      TYPE      STATE         CONNECTION         
enp0s16u1   ethernet  connected     Wired connection 1 
virbr0      bridge    connected     virbr0             
wlp1s0      wifi      disconnected  --                 
lo          loopback  unmanaged     --                 
virbr0-nic  tun       unmanaged     -- 

"lspci | grep -i wifi" gets me:

Code: Select all

01:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8822BE 802.11a/b/g/n/ac WiFi adapter

any help is appreciated.

The kmod-r8822be package from ELRepo should provide the driver for your wifi device. To be sure, we need to see your device's ID. Please show us the output from:

lspci -nn | grep -i net

That should be supported already:

Code: Select all

[root@here ~]# grep -i 10ec /lib/modules/3.10.0-1062.4.1.el7.x86_64/modules.* | grep -i b822
/lib/modules/3.10.0-1062.4.1.el7.x86_64/modules.alias:alias pci:v000010ECd0000B822sv*sd*bc*sc*i* rtwpci
CentOS 6 will die in November 2020 - migrate sooner rather than later!
CentOS 5 has been EOL for nearly 3 years and should no longer be used for anything!
