Internet Connectivity Lost After Update

[mgnapp]

Hello all.

I am posting my issue here because this happened during installation and have not been able to resolve it..... yet...... I just installed Mint 13 and during the install I lost my internet. I have a realtek 8111/8186 ethernet card and it seems that the system sees it but says "wired - cable unplugged". I am currently tethering my phone to get wireless through a USB connection and have no problems. The ethernet cable is not the problem. I suspect a driver issue. From all of the posts that I have dug through over the last 48 hours, and commands I have input in the terminal I have had no luck. Here is a little information, but I am at your mercy, so anything else you would need, please let me know! I am a newb, but I don't give up.

sudo ifconfig -a

Any and all help is much appreciated!!!

I see lots of others with this very same issue. Is this being worked on or am I just not asking the right questions to get this resolved?

DNS nameservers can be missing. Command cat /etc/resolv.conf tells if they are there. I have write-protected mine ..

Command nm-tool tells more info.

had a similar problem. Mint 13 was working perfectly until a kernel upgrade. then... all went to crap... was using the "remove Network.Manager.state" routine but that was a pain and didn't always work on first try.

nanowire (a forum user) suggested using Synaptic Package Manager to remove Network.Manager and replacing it with Wicd. That solved my issues completely. Might be worth a look.

I followed this fix, but no success. Here are the results:

gnapps@gnapps ~ $ sudo gedit/etc/resolv.conf
[sudo] password for gnapps:
sudo: gedit/etc/resolv.conf: command not found
gnapps@gnapps ~ $ sudo gedit /etc/resolv.com

(gedit:2591): GLib-GIO-WARNING **: Missing callback called fullpath = /root/.local/share/recently-used.xbel

What's next? And in case I haven't mentioned, I appreciate everybody's input so far. Just a big learning adventure. When I sleep at night, I dream about this terminal as though I am stuck in the Matrix!

It is a bug caused by new net controlling system. Network has to restart using command sudo service network-manager start and if you want not to start every time via command line, make a script.
gksudo pluma /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
service network-manager start
exit 0

Save, quit and reboot.

I just get this:

gnapps@gnapps ~ $ sudo service network-manager start
[sudo] password for gnapps:
start: Job is already running: network-manager
gnapps@gnapps ~ $ sudo service network-manager start
start: Job is already running: network-manager
gnapps@gnapps ~ $

I can't figure this out!
