installing Realtek 8821ce on RHEL 8

I am trying to install my wifi card driver on RHEL 8 for the 8821CE. I am temporarily using an 88XXau for a usb wifi adapter. I've been looking for a solution for a while and came across two main git repos: https://github.com/lwfinger/rtlwifi_new/tree/rtw88 https://github.com/tomaspinho/rtl8821ce/ the rtw88 still doesn't support the 8821CE Card as far as I can tell. I managed to install the /tomaspinho dkms module after editing the code and following the issues section to solve compilation problems related to kernel version: https://github.com/tomaspinho/rtl8821ce/issues?q=centos This basically involved changing some ifdef definitions to suit the old kernel that is using recent or backported code to my knowledge. Now I am at a point where the dkms module installed correctly and I can see the module loaded in lsmod output, but the card is still not detected and I wonder what I can do from this point forward. Thank you in advance for your help. lsmod: lsmod | grep 8821 8821ce 2023424 0 cfg80211 806912 2 88XXau,8821ce kernel: uname -r 4.18.0-193.1.2.el8_2.x86_64 dmesg: dmesg | grep 8821 [ 0.758821] pci_bus 0000:00: root bus resource [mem 0xfee00000-0xffffffff window] [ 3.187034] 8821ce: loading out-of-tree module taints kernel.
