Hi

So I finally gave the Live CD, which is based  Ubuntu 14.04. The
wireless works fine now.

But I have a sever problem with the wired network, which installed via
the systemsettings.

Every 1 min the net is gone, inspecting the error: the default gateway
is deleted. So I have to reconfigure the net, but every minute makes it
a PITA. The file in /etc/network/interfaces is fine though

I never faced that problem before (Using trinity 3.5.13 on Lucid and even
using R 14 on Kubuntu 14.04 (which gave me a problem with wireless, but
not that sever problem)).

I summarize:

    -  Kubutu 10.04 + Trinity 3.5.13  everything is fine.

    -  Kubuntu 14.04 + Trinity 14.04, wired more or less ok, wireless
       has a problem with tdenetworkmanager, wicd works fine though.

    -  Live CD based on Ubuntu 14.04, wireless tdenetworkmanager is
       fine, wired net breaks down every minute when configured by
       systemsettings.

My most pressing question, how can I get the wired net to work.

Thanks
