linux cards supported by rtw88_8821ce.ko driver

This driver supports your card. It is in Slackware current now. I did see you are running Porteus.
You did not say what release. From the write up on Distrowatch, their newest release is a RC2, and and an older kernel form a while back.
You could consider getting Slackware current from Alienbob. It can easily be put on a USB stick. He keeps it up to date, I would bet your wifi will work with it.
You could also look at what you have and see if rtw88_8821.ko is part of your distro.
Hope this helps.
