Hi

This is the first time I have such an experience. I installed Kubuntu
14.04 and trinity via

deb http://mirror.xcer.cz/trinity-sb trusty deps-r14 main-r14
deb-src http://mirror.xcer.cz/trinity-sb trusty deps-r14 main-r14

Everything went smooth wireless net can be configured with
tdenetworkmanager, but when I try to set up the wired net, via the
networktool I run into a problem.

I use all the parameters I used in previous trinity + Kubuntu 
installations (namely 10.04 and 12.04)
static IP number
DNS server
Gateway.

The connection works for a couple of seconds and then crashes the
problem see to be the Gateway, when I restart the configuration tool the
value has been deleted.

Anybody has an idea what do?
That is a very serious problem, right now use the Wifi connection, but
this has severe restriction in the network I am using.

Thanks
