Ubuntu Installation :: Internet Lost After Updating?
Mar 18, 2011
I partial updated the ubuntu packages after repeated messages. Finally it asked me to delete obsolete files and I clicked Ok. After some time the wireless internet Icon on the top right corner disappered.
Now I cant connect to internet by my router either wireless or wired. My wlan drivers are ok too. There seem to be no network whatsoever.
I was using dual boot (windows 7 and ubuntu 10.10) and it was going well. Couple of days ago I updated to Ubuntu 11.04 and everything was OK. Yesterday I cought some virus in windows, installed Microsoft security essentials which asked to update Windows. After update, dual boot is gone. It boots to windows directly with no option to choose between OS.

I've been having some problems trying to get a new netbook working with China Telecom's 3G service (works wonderfully in Windows, but still trying to figure Ubuntu out), so until I figure out the problem with this Huawei modem, I've written a quick python script to handle updates/installations on the Ubuntu side. (Synaptic does fine on generating download scripts for packages, but it needs an option to handle updates as well)
If anyone else has a use for this, you're welcome to use it. Please let me know what needs to be changed to make it work on your box.
I recently bougt an Asus N61DA with Windows 7. I decided to install Ubuntu alongside Windows, so I made the Ubuntu CD, just like it said. Then I inserted the CD and restarted the computer. I started the installer (ubuntu 10.10 64-bit) and chose the option where it says "install ubuntu alongside other operating systems", or something like that. So, the installation started, but then I lost the internet connection, and the installation stopped.I re-connected the computer, but the installation still wouldn't continue. I restarted the computer and then nothing happened. I've restarted it several times, but still nothing happens. I've inserted the Windows recovery CD, but it doesn't work
I cant change my user settings (password, login screen settings etc) after upgrading to 10.4 on my desktop pc. It says I don't have rights. I'm the only user, no other profiles. Otherwise seems to be working fine!
My PC lost power while updating. After booting, I run update once again and everything seems to be fine, except the message "could not do simulate: coreutils-libs-8.4-8.fc13.i686 requires coreutils = 8.4-8.fc13 : Success - empty transaction".
When I try using "yum update", I receive the error message below.
Loaded plugins: refresh-packagekit Setting up Update Process Resolving Dependencies --> Running transaction check
I am using Ubantu9.04 and before few days I have tried installing amsn.It prompted to dependencies for following packages :
1. farsight2-0.0.17 2. gstreamer-0.10.27
After installing that I have lost sound,and the error was :
"The volume control did not find any elements and/or devices to control. This means either that you don't have the right GStreamer plug-ins installed, or that you don't have a sound card configured."
I can install and update Fedora11 as well as other softwares at my office through internet. However, at home I don't have any net connection. Is it possible that I collect all files including their dependencies from my office computer in a pen drive and then update my home computer?
I have a number of systems with Fedora on them, they are connected to a network but are not allowed to connect to the internet. So I am trying to find a solution to patch these systems in a simple way.My solution which i thought of, however, still having a problem with is as follows:
1- Download the files from the "repodata" (e.g. for "update" repository) using a machine that is connected to the internet.
2- Copy these files(e.g. using flash drive) to one on of these Fedora systems into the /var/cache/yum/i386/12/updates (or /var/cache/yum/updates for older versions).
3- Run "yum -C check-update" (-C so it will not try to update and will use the local files). (I am having a problem at this step and I get this message "no such table: packages", the solution that i found on the internet suggested cleaning the cache which is not what i want to do!).
4- After getting the list of needed files I will parse the primary.xml.gz file and grab the actual file names then append the base URL to them and save it into a file.
5- take that file to the online machine and run wget to grab all needed patches.
6- Take the files back to the system and put them in (i think /var/cache/yum/i386/12/updates/packages/) and run "yum -C update" However, now i am having a problem with step 3 and also not sure if step 6 is correct.
So does any of you guys know how to solve this, or if there is a better or easier way to do this??* Keep in mind that those machines are not allowed to connect to the internet or even connect to another machine that is connected, but we still need to patch them and keep them secure.
I ran up2date yesterday and it installed a few new MySQL packages as well as a new kernel.
It got through everything up until it went to install the smp version of the kernel, and up2date spit an error at me and quit.
The problem was that my system keeps old kernels and /boot was full, so it couldn't add the new files there. No problem--I manually removed (via rpm -e) six or seven of the old kernel packages (there might have been a dozen or so), ran up2date again, and it successfully installed the new kernel. Great. So I rebooted the system.
And when it came back up... MySQL didn't start.
I tried to manually start it just to see, and was greeted with "chown: 'mysql:mysql': invalid user" Yikes! Sure enough, a look at /etc/passwd showed NO user "mysql." I quickly tried "useradd mysql" but it wouldn't go for that because there was a GROUP mysql.
I checked to make sure that there was no user with an id matching the group id of mysql and then manually added mysql back to /etc/passwd and /etc/shadow.
After doing that I was able to start the MySQL daemon and it now properly starts up and runs fine after rebooting.
So basically, it's fixed, but I still don't exactly understand what the heck happened. Updating to a new MySQL rpm and having up2date fail while installing a new kernel somehow deletes my "mysql" user from the system? I shouldn't have to be manually modifying /etc/passwd and /etc/shadow because of an up2date error, I wouldn't think.
Edit-- This is a RHEL 4 system now running 2.6.9-89.0.20.ELsmp on a Dell PowerEdge 1750..
I recently installed Debian "Squeeze" onto a Thinkpad T420, alongside Windows 7. During the installation Debian was unable to detect my NIC (Intel 82579LM), but otherwise the installation completed normally. I've installed the required e1000e drivers, and added "alias eth0 e1000e" to the modules file. Using lspci I can see that the computer detects the card, but still fails to load the drivers for it.
I'm at a bit of a loss, as this is my first time using Linux. After a bit of searching it looks like the 2.6.38 kernel resolves the issue with this card, so I guess that's my next step.Unfortunately all the installation instructions I've found assume an internet connection.Is there a simple way to update the kernel without a connection, or -even better- an install disc with 2.6.38 so I can start from scratch?
my Internet connection stopped working suddenly after updating the packages using synaptec package manager and rebooting it..can anyone say me why did this happen.BTW,mine is ubuntu 10.10 and i am absolute new to linux.I had to configure my n/w connections right from the scrap again
After updating to kubuntu 11.04 natty, I have a problem with my internet-connection. The problem happens when I use VoIP-Software like Skype or Twinkle and also when using ktorrent.
When using the mentioned software, after 30-90 seconds the internet gets very slow. In f.e. skype, I can hear the one I phoned very badly.
I use kubuntu on a desktop-PC with a Linksys USB-Wlan-Stick. Detailed information is below.
Code: uname -a Linux pr1-desktop 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux
After a recent installation and update I am having problems connecting to the internet even after following the steps in [URL]... Configure a network card in Suse/openSUSE...." It doesn't always connect when I boot and there is no connection icon on the panel nor the KDE desktop. Can someone assist me with this problem?
Updated to the latest version several weeks back. Everything loaded fine and system works fine.....except for the internet (wireless AND wired).
I'm still real new at Linux so I just stopped and switched back over to Windows (dual-boot) out of frustration. Figured I'd finally tackle my problem today. Internet and everything worked perfectly before upgrade and now......NOTHING. I hooked laptop (computer running Linux) up to hard line on main computer.....still no internet.
The internet has been working happily on my Mythbuntu machine for many months but stopped working overnight.If I try to do "sudo start networking" I get a "Job failed to start" message.There's also a solid orange light on the ethernet socket.As it's been working for months, I don't think my interfaces config needs updating.Looking at what's been updated recently on the system:
1) I've configured the machine to wake from USB. It was working for a couple of days so I don't believe this is the issue.
2) I set up wake-on-lan with ethtool. Again, this was working (although it did seem to disable wake-on-usb and required a reboot to fix)
3) Update to 11.04 - I said no to this, as 10.10 was working very nicely indeed.
I've disabled wake on lan and rebooted. No joy.
ethtool detects the ethernet controller ok and it's listed in lshw.
I'm running 10.10 and I uninstalled some files through synaptic and it also removed a lot of other packages which messed up my whole system. I lost the connection to the Internet and also the taskbar. I don't know how to re-install those lost packages because I have no net connection. How can I fix this? This is what I removed:
Completely removed the following packages: apt-xapian-index libboost-python-dev python-xapian
Three months ago my daughter went off to college with a new computer. I zapped her old system and successfully installed Ubuntu 9.04 from a CD. Everything worked fine including all the peripherals and the wireless internet connection. I was able to download and update applications without a hitch. Great system and so much cleaner and quicker than Win XP on the old machine. Then the system was shut down and lay idle for three months.When I fired it up a couple of days ago, all seemed normal except I could no longer access the internet even though the wireless network icon showed four or five bars. I first discovered the problem when I tried to update though Update Manager and noticed that 22 identified files could not be fetched. Neither Firefox, Skype nor Goodgle Earth can connect.
The router is a Linksys WRT54G router that connects to the computer through a Linksys WUSB54G USB network adapter. The router serves three other non-Linux computers without a problem, including one using the same model network adapter.I don't have much experience with Ubuntu, but this is some of the information I have been able to generate.
I tried a few of the recommendations found in other sites, but nothing seems to do the job. I am perplexed because everything was great until I shut down the system for three months and then started it up again. I appreciate any assistance and would be happy to provide additional information as requested.
I am running ubuntu 9.1 on a Dell Dimension 2400. After installing ubuntu on the pc, it was automatically recognizing my router and connecting to the internet fine via ethernet. Then, my roommate unplugged the router and it won't recognize it. I can't access my router settings, and ubuntu is recognizing it as "inactive" but every other computer in the apartment runs fine. My PC uses a broadcom ethernet controller, and my router is a Linksys wireless N.
I added RAM to my Acer (dual boot Windows XP / Ubuntu 9.1). Windows continues to work. Ubunty will no longer recognize the internet connection. I don't know if adding the memory is what did it, but I am puzzled why I can use the ethernet card from Windows but no longer from Ubuntu.
I was downloading the Android SDK when, mid download, I lost my internet connection. Now I cannot connect to the internet via hardwire connection. I can still connect on Vista, and I can connect via wireless, but I cannot have a hardwired connection.
I was running 8.04 and my internet (Comcast) comes via a Motorola SB5100 cable modem then into a Netgear router then into my Dell. When I upgraded to 10.04 yesterday, I lost the wired connection. The wireless connection still works fine, but I have not been able to get a wired connection. Also, most online solutions reference the Network Manager, which is nowhere to be found.
Anyone have any solutions? I would be willing to revert to 8.04 if needed, as that worked fine, and obviously I quite regret the upgrade!
As I view it, Ubuntu has a great security risk in that it still allows internet access when the VPN connection has been lost, for whatever reason. As it is now, when the VPN connection fails you get bumped back to using your regular IP, and whatever you are doing becomes transparent to anyone watching. This is simply unacceptable for an allegedly secure platform. Does anyone know of a way to fix this with a script/program, or is there a distribution/OS that allows this? Windows re-dials the vpn automatically, but still allows internet access in the mean time.
I am a non-techie, have been gratefully using Ubuntu 8.10 for a few years for the basics: email, web, documents, photos. I have somehow lost my internet connection, but strangely my email still works...!?!? My router is showing all the correct green lights, but I cannot get to any url. I am posting this thread via work (windows) pc. I have searched on this forum and in anticipation have done as much homework as possible, see below.I have a Netgear wired router. I cannot find Network manager on the menus and tried this from the terminal:
Code:
network-manager bash: network-manager: command not found networkmanager
I do have a problem with my internet connection at home, I've a Huawei router and ubuntu 10. When I connect to the internet whether wireless or wired I become able to surf the internet for less than 10 min then it cuts off! and to be able to surf it again I need to restart the whole system!
I used this command to restart the networking but in vain Code: sudo /etc/init.d/networking restart
On windows I do not face this problem with the same internet connection. I do not face it either when I'm using my campus wireless connections using ubuntu/windows!, so the problem is related to my home connection+ my OS.
