Hello Linux in the UK!
I’m connected to the Internet, but I an empty delta-like symbol in my GNOME/Ubuntu panel. I get this message:
Error displaying connection information:No valid active connections found!
I don’t know what this means for functionality, but I know it’s not right.
Would anyone here possibly have any ideas how to normalize my connection information?
Thank you,
perknh
Hi perknh … so you are able to connect, it’s just the panel applet that’s playing up and not displaying the connection info ?
I’m wondering if network manager is starting at bootup before the connections become active … so let’s see what happens if we restart it AFTER bootup…
what happens if you run:
sudo service network-manager restart
then if necessary:
sudo killall nm-applet
then
nohup nm-applet
and what’s the output from:
ifconfig
Hello PCNetSpec,
PCNetSpec, I can’t seem to get beyond this:
perknh@trustywolf:~$ sudo service network-manager restart
[sudo] password for perknh:
network-manager stop/waiting
network-manager start/running, process 2581
perknh@trustywolf:~$ sudo killall nm-applet
perknh@trustywolf:~$ nohup nm-applet
nohup: ignoring input and appending output to ‘nohup.out’
I seen unable to enter the ifconfig command in any meaningful way. Therefore I can’t obtain any output from it. :-\
This is ifconfig by itself:

I’m stumped as how to add it to the proceeding commands.

What’s the contents of
gedit /etc/udev/rules.d/70-persistent-net.rules
?

And what kind of connection are we talking about here .. wireless, wired, mobile dongle?
Ethernet --using the same modem that you helped me configure months ago in Peppermint forum. (By the way, Peppermint 6, on my external hard drive is not having this problem.)
What kind of connection are we talking about here … wireless, wired, mobile dongle ?
if wireless … is the wireless actually working ?
[EDIT]
And can you post the output (if any) from:
dpkg -l | grep biosdevname
Now, after enabling Wi-Fi, I can’t seem to get back to my Ethernet connection.
Maybe something went wrong when I installed GNOME core yesterday.
I can reinstall if you think I should.

NO, not yet
What’s the output from:
dpkg -l | grep biosdevname
and is the problem that JUST the ethernet info for the WIRED connection isn’t displaying … but the ethernet WAS working ?
perknh@trustywolf:~$ dpkg -l | grep biosdevname
ii biosdevname 0.4.1-0ubuntu6.2 amd64 apply BIOS-given names to network devices
and is the problem that JUST the ethernet info for the WIRED connection isn't displaying .. but the ethernet WAS working ?
Yes.
what’s the output from:
sudo apt-get remove --purge -s biosdevname
perknh@trustywolf:~$ sudo apt-get remove --purge -s biosdevname

Okay, what’s the output from:
lspci -vnn | grep -i net
perknh@trustywolf:~$ lspci -vnn | grep -i net

OK, run:
sudo apt-get remove --purge biosdevname
then
sudo gedit /etc/udev/rules.d/70-persistent-net.rules
and make it read:-

SAVE the file and exit gedit.
REBOOT ← IMPORTANT
Once rebooted, see if the connection info is displayed, and post the output from:
ifconfig
PCNetSpec, I’m writing to you from Peppermint because I got this notice:
[i]The following page has become unresponsive. You can wait for it to become responsive or kill it.
The Linux Community Forum
[/i]
I’ll go back to it, PCNetSpec, but I’m having a tough time connecting to it. I just wanted you to know what’s been going on.
In the meantime, thank you very much.
perknh
was that before or after making the changes I specified and rebooting ?
(after uninstalling biosdevname you probably will loose the interweb over the ethernet connection until you’ve made all the changes and rebooted)
Peppermint to the rescue eh 
Yes, and Peppermint to the rescue again!
No, there is no connection display any longer at all. I could see the Ubuntu desktop, and I did go into Settings and Network connections (but not into Chromium or Firefox browsers which say there is no network connection), and I read this from Ubuntu:
The System network services are not compatible with this version.
That’s it!
What happens if you run:
sudo gedit /etc/udev/rules.d/70-persistent-net.rules
and make it read just:

SAVE the file, and REBOOT.
Okay! I’ve got to first figure out how I’m going to get to these new edits in order to copy and paste them into Gedit at Ubuntu. I need to do this first because I now have no functional browsers within Ubuntu in order to come here to this site! On top of all of this, I need to step out for a while for breakfast. I usually eat alone so I will ponder all of this while I’m having breakfast! 
Thank you, PCNetSpec. I will now go eat breakfast, and I will ponder how I got myself so deeply into such a mess so effortlessly! 
perknh … you shouldn’t need copy/paste
it’s only a single command … then remove the first entry in the file
Save and reboot.
