location: ubuntuforums.com - date: December 10, 2008
Yesterday I tried to use "xnetcardconfig" to setup my wired network yesterday, today when i turned on my computer i found the icon of network manager showing x like no connection , right click on the icon and select "connection information" an error message appeared saying:
Error displaying connection information:
No valid active connections found!
Right click on the icon again and select "Edit connections"
i found my connection "eth0" gone , nothing was there , the add button is activated.
Now i have no problem in my network, i tried browsing the net through Firefox and its OK ,torrent is working also, but i just want to fix the network manager problem to work like before.
I tried to reinstall the packages : network-manager-gnome and network-manager, then restart the system but without success.
Any help will be appreciated.

[SOLVED] Mint / Ubuntu mobile broadband connection problems
location: linuxquestions.com - date: October 31, 2010
This subject has been addressed before, But I didn't find one regarding Australian Providers. The particular one I had trouble with was DODO - which actually uses the Optus newtwork. I am still gathering information as to how it was achieved on my laptop, as it was done for me by somebody else. But I will post the answers as soon as I get the information
Any comments or findings or questions in the meantime would be moat appreciated for they will help with the goal to collect all the different angles, so that Newbie members like myself will be able to sift through and find the solutions which work for them.
Ubuntu kills internet connection
location: linuxquestions.com - date: May 10, 2005
Whenever I boot up ubuntu 5.04, it kills my internet connection. I have a Netgear 8 port hub, which is connected to my SMC 7004ABR router, which is plugged into my Zoom ADSL modem. One box is Ubuntu 5.04 and the other is XP. Once the Ubuntu box boots up, neither box can access the internet. The only way to get back on is shut all hardware down and restart. Also, my internet connection has slowed from about 1200 kbps to less than 400 kbps. Here is my /var/log/syslog file (followed by output from "ifconfig -a" and "route -n":

Ubuntu Error Logs

NOTE: Google Chrome is having some issues with drop-down lists and I can't see them, would a mod please change the prefix to the appropriate one?I Think [Ubuntu] is good enough, but if there's a better one... Thanks.
So I just got a crash with some numbers and a "not enough swap space" error, and I'm wondering if there's an error log that Ubuntu wrote somewhere. Any help? I think it's an OS issue and not a program issue.
Thanks in advance.

I was trying to dual boot windows XP pro with ubuntu hardy heron (ubuntu installed first) and I used this guide: http://apcmag.com/how_to_dual_boot_l...lled_first.htm . I thought everything was fine, windows was installed, then I went into Gparted (GNOME partition editor) everything looked to be fine, I flagged the ubuntu partition as the "boot" partition and made sure that the "boot" flag was off the windows partition, then took the Gparted dvdr out restarted and I get this message:

Ubuntu Error: autorunning software Permission denied
location: ubuntuforums.com - date: April 24, 2009
I will keep this short. New to Linux/Ubuntu.
I bought a used HP W Ubuntu 8.04. I want to install
my wireless adapter software but keep getting an error
message that says: Error autorunning software. Error
starting auto run program Permission denied.
I suspect this is because the software was written for
Windows and cant run on Linux. I also think this
computer was part of a network and I need to
change those settings. I am kind of new at all of this
How do I get my Linksys software to run, and how do I
change my computer to run off a wireless router.

Triple boot: XP, FC6 and Ubuntu: Error!
location: linuxquestions.com - date: April 22, 2007
This is my current filesystem settings (i know it's trashy but i didn't think it through before setting it up):
/dev/sda1 - XP C:
/dev/sda2 - XP D:
/dev/sda3 - Fedora Core 6's /boot mount point
- /dev/sda5 - FC6 /
- /dev/sda6 - Ubuntu /
- /dev/sda7 - swap
The grub menu.lst was auto-generated by the ubuntu installer. All works well, except when i want to boot fedora, it says something about 'can't find LABEL /ubuntu'. I've also tried editing editing the FC6 entry so it resembles with ubuntu's (got the UUID from fstab) but this generated a kernel panic. These are the entries:
title Ubuntu, kernel 2.6.20-15-generic
kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=12c8a11c-ff66-48a1-b16e-037cc8f955b0 ro splash
# This entry automatically added by the Debian installer for an existing
# linux installation on /dev/sda5.
