Ok, you can click the check-mark icon on that post to un-mark.
On 23 you can install the antiX 5.10 kernel from "MX Package Installer" with 2 clicks only, then boot with it using the "Advanced Options" on Grub, then try.
If still not: It may be due to Network Manager, that version (that sometimes happens, and only installing ConnMan solves it (as an alternative to NM) )
Edit: Grammar.
