Not working for 4.18.0-338.el8 (Centos 8 Stream/Rocky linux 8.4) #146

Open alexisfrjp opened 2 years ago

alexisfrjp commented 2 years ago

I modified the code to support Centos 8: #if (LINUX_VERSION_CODE >= KERNEL_VERSION(5, 8, 0)) to #if (LINUX_VERSION_CODE >= KERNEL_VERSION(5, 8, 0) || RHEL_RELEASE_CODE >= RHEL_RELEASE_VERSION(8, 0))

USB dongle: Bus 001 Device 011: ID 0bda:c811 Realtek Semiconductor Corp.

I installed the driver but once I plugged the usb dongle in, dmesg shows:

Hello @luckylittle and @alexisfrjp ,

Have a similar issue here when trying to build the driver for CentOS Stream 8.

did you managed to workaround this issue ?

Many thanks in advance

alexisfrjp commented 2 years ago

No, it has never worked, I gave up my 500yens usb dongle.

I was able to make it working with https://github.com/brektrou/rtl8821CU/commit/db47217e31b95b4a760a58d6c4790631d1da4896 fix by adding:

if (LINUX_VERSION_CODE >= KERNEL_VERSION(5, 3, 0)) || (LINUX_VERSION_CODE == KERNEL_VERSION(4, 18, 0))

instead of just

if (LINUX_VERSION_CODE >= KERNEL_VERSION(5, 3, 0))

in whole patch though you need to create wifi interface using nmtui once module is loaded. It is now working like charm.

I used the code from the following repo: https://github.com/morrownr/8821cu-20210118
