Ok, that solved this issue. That is I deleted the link copied the
resolv.conf file
which contained the lines.


# Generated by NetworkManager
nameserver 147.96.1.9
nameserver 147.96.2.4




from /run/resolvconf/resolv.conf to /etc and run
chattr +i resolv.conf

Rebooted and now everything is ok, when rebooting. However I noticed
that I did not quite describe what I did:


    -  I used /opt/trinity/bin/systemsettings for setting the wired net


    -  and tdenetworkmanager for the wireless net.


Maybe this is not smart and I had no problems, when passing from wired
--> wireless but problems when passing from wireless --> wired since the
wireless deleted the DNS server entries.

I will report  this in a new mail with a new subject.
