Wireless adapter not found

Post by mohit131 » 2020/07/22 02:22:28

I have installed CentOS 7 on my new HP laptop which has Realtek Semiconductor Co., Ltd. RTL8822CE 802.11ac PCIe Wireless Network Adapter which I found out using 'lspci'. But I can't connect with wifi. It says wireless adapter not found. I have searched in \lib\firmware\rtlwifi but cant find rtl8822ce file. My laptop don't have LAN port, so I need wifi to work.

What is the output of "lspci -nn" ? Post the line for your wifi device. It will show the device IDs [xxxx:yyyy].

I suggest you file a request to build a driver for RHEL/CentOS 7 at ELRepo's bug tracker. Be sure to provide the info presented here.

I was not able to find a driver that supports the device ID pairing [10ed:d822]. However in the ELRepo's bug report you filed, you showed [10ec:c822] instead. This one is supported by the rtwpci kernel module as noted in there.

I have updated kernel to the latest version and everything works fine.
Thank you for your help.
