Post the output from lspci -nn | grep -i net so that we can see the adapter. If it is a USB adapter then post the relevant output line from lsusb.py instead.

Sorry, that was a typo in my reply, should have been lsusb.py but lsusb does just as well so no need to run it now.

I checked on my CentOS 7 system and I cannot find anything that supports that chipset. Your best chance of finding a driver for it is to Google "ELRepo", find their bugtracker, raise a ticket there called a Request For Enhancement (RFE) and ask them if they might be able to build the rtl8192eu kernel module as a kmod package.

It doesn't appear to be supported on CentOS 8 either.
