Well.. that seems to have made things only worse (we have even more PCIE errors now..)

What do you mean with username and password, you have PPPoE service?
KolibriOS does not support it (yet). A solution can be to use a router that does the PPPoE for you..

Doczom The driver has been updated in #9146 and should work also for you now.
For "username and password from the provider", we still do not have support.
