[SOLVED] No Network connection at all after update & reboot

Postby aalemann on Thu Nov 29, 2012 4:08 am

Hi,

yesterday evening I installed Linux Mint 13 Mate in a dual-boot option with Windows XP. Everything was fine (after I convinced the boot-manager to also recognize linux....). Then I installed all recommended updates and switched from DHCP to a static IP address (Menu -> Control Center -> Network).

Then I switched to PC off and today I switched in on again and during the boot of Linux the following messages appeared:
"configuring networking" and
"60 seconds more to configure networking"

After that linux started without any network connection. I typed
Code: Select all
sudo service NetworkManager start

which gave me the error message the NetworkManager is an unrecognized service.

Then I did this
Code: Select all
sudo dpkg-reconfigure network-manager

trying to reset any configuration. No success.

Then I reinstalled the network-manager by typing
Code: Select all
sudo apt-get --reinstall install network-manager


After rebooting, the system tray icon has vanished, and I have no connection at all.

This is the output of the command
Code: Select all
sudo inxi -SNx

Code: Select all
System:    Host: ipfpc105 Kernel: 3.2.0-23-generic x86_64 (64 bit, gcc: 4.6.3) Desktop: N/A Distro: Linux Mint 13 Maya

and of the command
Code: Select all
sudo nm-tool

Code: Select all
NetworkManager Tool

Any ideas?

Linux Mint is funded by ads and donations.

OK, my internet is working again, what I did is
/etc/init.d/networking restart


But I still have the problem that the system tray icon disappeared.
And I don't know what caused my problems, but I'd like to know.

Any ideas?

I just switched my Mint 14 MATE machine to a static IP and my tray icon went away, too. I think it just might be the way MATE works: there are no network connections to manage (nm-tool says "unmanaged") so the tray icon isn't there.

There was another wrinkle, too. After I restarted my machine I had a static IP and could ping a numeric IP address, but I had no DNS even though I had entered my router's IP address as the DNS server in Control Center > Network. I had to do

Code: Select all
sudo nano -w /etc/network/interfaces

and add the line

Code: Select all
dns-nameservers 192.168.1.1

for DNS to work again.

If MATE is a bit shaky with static IP addresses then it might be easier to set up a DHCP Reservation for that machine so it can use DHCP (and continue to be "managed") and still get the same IP address every time.

Thanks for your answer.

OK, to me that sound reasonable.

The other problem you mentioned (the DNS server) did not appeared for me.
