Yes AROSTCP is present in Env-Archive, but the content might be different, "when the connection works", delete the folder from AROSTCP from Env-Archive, and exstitute it with that of ENV:
AROS like Amiga, after a warm reboot reads the preferences from ENV, while after a Cold reboot, the preferences are taken from Env-Archive.
I use this procedure for the DVDLive and PendriveLive of my AROS One Distribution, for all those who use AROS One on a VM, this way the connection is active and functional even from the DVD Live or Pendrive Live.
You can do this test, when the network works, delete the data from ENV, and you will notice that the network no longer works, because I will read the data from Env-Archive.
