systemsettings and tdenetworkmanager switching between wired and wireless problem with DNS server

Hi
- 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 in the resolv.conf
So usually I manually copied a backup of resolv.conf to /etc and run
sudo /etc/init.d/networking restart
But this does not work anymore in 14.04 as we discussed. So what is the
smart way of configuring wired/wireless and what is the smart way of
switching between wired/wireless????
Relying entirely on systemsettings or on tdenetworkmanager?

yes my experience with NM is that is picky on others dealing with network
settings, so I recommend using only NM. Do all your configurations there
and clean up the rest. This is what I can recommend.

Ok I tried that. I deactivated wired in systemsettings and tried to turn
it on via tdenetworkmanager. Did not work out no connection.
I attach a screenshot of my configuration data

Have you tried connecting your wired connection via DHCP? What happens?
To what PRECISELY are you trying to connect? My equivalent settings would be:
IP address 192.168.0.2
Netmask 255.255.255.0
Gateway 192.168.0.1
I connect to the Internet via a modem-router, which connects to my ISP.
But I find it better to use DHCP in all individual machines (from Kindle, to
the TV, to my desktop) and have the router dish out set IPs to named Mac
Addresses (including wireless ones, so, FWIW, my Kindle always has the same
IP).

I cannot, my university does not support DHCP via wired, only via
wireless.

I have feeling that the setting of the DNS servers is not correct, but I
don't know what to do.

We haven't really got enough information about the network.

I am not sure what you mean.
Static Ip 147.96.12.44
Gateway 147.96.12.1
DNS Server 147.96.2.4
DNS Server 147.96.1.9
These are the data I inserted in Kubuntu's systemsettings and the wired
connection works, I tried the same setting (as my screenshot indicated)
but the wired connection does not work.

If using only TDENetworkManager doesn't work, why not try using only Kubuntu?
Meanwhile, get up the wireless access that works then do:
$ ip addr
and post the result, to see if it will give either me or someone else a clue
as to your network.

Uwe is saying to use 8.8.8.8 and 8.8.4.4 as your DNS servers just to
check. The system may not be able to reach the old ones regularly. The
above ones are Google's and they do allow or at least don't stop people
from using them.

No, Uwe has the problem. I suggested Google's for exactly that reason, but
Uwe did not report back.

Ok I tried it out. I first disabled my wired net via systemsetting and
then called tdenetworkmanager.
I attach the screenshot2 of the setting and the symbol of the icon,
which indicates IMHO that it does not connect to the wired net.
Please tell me whether the screenshots arrive.

I'm so glad someone that knows a GUI network manager from a well shoed
racehorse has joined in this conversation!!

It sounds as though the two were being asked to give conflicting orders. I
should remove it from one before testing the other. It may simply not have
been working because system setting told it not to.

The screenshots arrived, but I am afraid that I am not used to sorting
networks out by looking at icons and I'm not really sure what I am looking
at.
Did you run
$ ip addr
while the wireless was working?
If it is working, then do:
$ ping 8.8.8.8
followed by
$ ping www.google.com
and send us the results. You may have to use ^C to stop the ping command,
depending on how your system is set up.
DNS shouldn't affect connection, only finding sites.
I still have no picture of your network at all.
How (apart from the icon) do you know whether it is working or not?

Uwe - sorry, I should have asked. Do you know how to use a terminal?
(Otherwise said, do you know how to work at the CLI?)
