Ubuntu Networking :: Wired Network Settings Lost On Reboot
Jul 30, 2010
I have installed Lucid in a new laptop. Things are running OK except for the following problem:
I connect to the network/Internet using Wired ethernet (TCP/IP) with static IP. Everytime I reboot/restart my network configurations are lost and I have to re-configure. I have googled this problem and have seen a few posts/bugs in launchpad etc. for what appears to be the same issue...but unfortunately I am not getting a clear solution to this problem.
Just for clarity, I am using the following commands to re-configure my network everytime:
Also note that I have already tried editing the /etc/network/interfaces and the /etc/resolv.conf files. But it seems that these are not being picked or are being overridden.
I turned down my txpower with the command: sudo iwconfig wlan0 txpower 3 Which works to fine turn down my broadcast power from the default value of 15 dBm to 3 dBm. But it is reset every time I restart Ubuntu 11.04 to the default value of 15 dBm. How do I save my modified txpower settings so they don't reset after a restart? It is really annoying having to re-enter the command every time I reboot my computer!
Im new to fedora 11 and iptables, and i need to set the following set of instruction so VirtuaBox can accept request from lan, to the mailServer in the guest os, but after restart fedora i have to input it all again.How can it become permanent entry in iptables.
I had some problems installing 10.04, which I'm not going into here unless I have to, but it appears to be up and running now except my PC can't access the network, even though it's wired. This is the first time I've tried putting on a new build by myself as my son always used to do it (my PC used to belong to him many years ago, and is old, like me.)
My first post. I lost all connections to the internet on my Linux Box Yesterday. I have checked my broadband connection and router. OK because I am using them to sent this from my laptop. I have 2 ethernet cards - no indication of a problem with either so I suspect for reasons unknown I have lost all my network settings. The Desktop User Guide says go to the Network Settings Window. I used to have a widget on the Menu Bar which enabled me to check the settings but for some reason it vanished a month or so ago and I can't find how to get it back.
PS In the meantime I am stuck with this crummy Microsoft box the interferes with everything I try to do.
After i install it i lost my internet connection . i got a message " Wired Network " " you work offline ". i use cable ADSL ,.... my Pc information HP Pavilion 6700 running with both Window 7 & Ubuntu 10.10 note... my network connection work correctly on W7.
I installed Kubuntu on my Toshiba A135 with no problems at all...everything works: sound, wifi, LAN, etc...BUT whenever I reboot/restart the computer my Display and Audio settings revert back to default, and it doesn't happen when I log out, just when I restart/shutdown the computer. I have an Intel 945GM chipset and I have set my external Acer 23" monitor as the default and only monitor with a resolution of 1920x1080@60Hz using KDE's System Settings...And I chose to disable the laptop's internal monitor...but whenever I restart, the display returns to a 1024x800 cloned resolution (the default one)...which by the way looks hideous on a 23" monitor. And also the sound mixer goes back to the default levels.
So, can anyone help me out? I've been using Ubuntu for over 3 years and I've never had any problems like this one. I have just fell in love with Kubuntu, it looks and runs great, but this problem/bug is keeping me from being comfortable with it... I've been reading some things about XRandr and some commands and stuff and nothing have worked until now. I wonder, is it a common bug in Kubuntu or maybe an erroneous setting in the session manager....?
I'm having mysterious wired network problem with my Karmic/9.10 machine. It hasn't been in network a while, but now I finally got the cabling done. I can't get the IP from dhcp server (TW-EA510), and static settings doesn't work either. Fresh cabling showed OK 1Gb connection on tester, and win7 laptop works fine. I even tried with long cable though the rooms, but it doesn't help, so it definately isn't the new cabling.
Log from the router after issuing #"dhclient": Feb 16 23:01:43 DHCP SERVER: DHCPDISCOVER from 00:01:29:fb:c5:d1 via br0 Feb 16 23:01:43 DHCP SERVER: DHCP offer to 00:01:29:fb:c5:d1 Feb 16 23:01:49 DHCP SERVER: DHCP request from 00:1b:ea:c8:a0:ba Feb 16 23:01:49 DHCP SERVER: DHCP ack to 00:1b:ea:c8:a0:ba Feb 16 23:01:54 DHCP SERVER: DHCPDISCOVER from 00:01:29:fb:c5:d1 via br0 Feb 16 23:01:54 DHCP SERVER: DHCP offer to 00:01:29:fb:c5:d1 Feb 16 23:02:03 DHCP SERVER: DHCPDISCOVER from 00:01:29:fb:c5:d1 via br0 [Code]....
Motherboard is some old Lanparty with two ethernet ports, NVidia CK804 and Marvell 88E800 rev 13 Gigabit netwok adapters, neither of them works. At least another of them has been worked earlier when I last got it wired. It's been a while, so I'm not sure which one of them and with different router if that matters.
I have just upgraded to Lucid Lynx. Just after that the borders of disappeared. Anyway, I found out I can get them back if I enable Standard Visual effects from the appearance menu. The only problem ?i have is that the options don't get saved and I need to do this over again every time I reboot.
I run OpenSuse 11.4 with KDE 4.7. When I change the positions of icons in the main plasma panel, or reshape folder view plasmoids on my desktop, these changes are lost when I start my computer the next time...
I'm running PCLinuxOS 2010.07 (KDE) on my Acer laptop with Intel Mobile GM965/GL960 Integrated Graphics Controller. I have an external Acer monitor that displays at 1920*1080. I have selected my laptops internal screen to be disabled and use the external screen. The PC LinuxOS Control Centre selected the 'Intel later than 810 driver'. All works well whilst I'm using my system but when I turn off and reboot the settings are lost and I have a 1280*800 display on my laptop and the same on my external screen. Resetting the Display using Configure your Desktop allows me to reset the external monitors to my preferences but how can I make theses settings permanent?
I've installed Fedora 12 KDE using VMWare, but I can't for the life of me get my display settings to stick. When I change the resolution, my display responds appropriately but upon logging out or rebooting, these settings are lost. Am I missing something completely obvious here?
Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?
I running Ubuntu ver 9.04 I have 2 problems that I think are related. After finally making a network connection I updated Ubuntu, and after a reboot I lost my network connection again.I updated the following file nm-networkmanager-settings.conf and saved it. After another reboot I then lost my network connection icon and it also does not appear under System > Preferences. I tried to then update the same file and can not save it, I get "could not save file".I have tried sudoedit, sudo gedit, gksudo gedit and some others that I cna not remember now and all give me the same result
Running Ubuntu 10.10 on a Dell 710m. Fresh install of OS yesterday. Initially I had wired connection but no wireless. So I started chasing threads & trying different downloads & commands [WITHOUT KNOWING essentially what I was doing; throw your rocks at me HERE] & now I have lost the wired connection also.
Also: [a] If I go into System > Administration > Additional Drivers, I get "No proprietary drivers are in use on this system."
[b] As far as being able to copy a downloaded driver [using a working M$oft machine with net connection] onto an SD card & transferring that driver to the Dell laptop, I have tried formatting 3 different SD cards with the Dell, & each time I come up with various failure errors--& I have no idea why something as simple as formatting an SD card isn't working.
So, when I booted up, the wired connection was automatically detected and in use. Whenever I suspend my computer and then resume it later I lose the wired connection. It is detected (seen) by Networkmanager, but I can never connect. I found a way to restore the connection, but it is manual and I was wondering if I could automate this process every time I resume. Details follow:
After I updated ubuntu 10.04.3 and restarted my PC, something weired happend and my wired connection was completely lost. I tried different things but it seems that I have lost my ethernet connection. I only have ethernet card and the interface was set to eth0 which is not recognized anymore.
The /etc/network/interfaces includes the following commands, which btw I tried to play with a bit by commenting and uncommenting the lines but was not helpful (but this is the original one):
Also in /etc/udev/rules.d I deleted 70-persistent-cd.rules hoping that it would be automatically regenerated but it did not,
I installed Lucid a week ago and have been having a blast with it after a two year break from Ubuntu (been using Mandriva). So the other day I went to hibernate the system and it froze. I naturally did a hard reset and when I log back in, no network connection. That is to say, the system tray says it's connected but there is no LAN light on the router or network card. ifconfig shows it's connected too. When I boot into XP (cringes) it works just fine.
No specifics ATM but the card is a D-Link PCI with a Realtek R8***** chipset
I have entered my primary and secondary DNS addresses through Network Configuration tool (system-config-network). But whenever I reboot the system it loses the DNS addresses. Following another thread, I tried changing the PEERDNS=no in ifcfg-wlan0; but it didn't work. I also put both DNS addresses in the ifcfg file, but that didn't work either.Does anyone know a solution to this?$ uname -aLinux fedoralinux 220.127.116.11-170.2.24.fc10.i686 #1 SMP Wed Feb 11 23:58:12 EST 2009 i686 i686 i386 GNU/Linux
I have Fedora 10 with 2 nic's and have used the firewall tool, network manager, etc.,then disabled the firewall front end and wrote my own iptables rules but can not even enable eth1 to use it. Tried 2 different common cards (like a network everywhere 10/100) Service network restart says eth1 not there.
Right now Ive:
eth0 connects direct to internet via my cable ISP.eth1 I've set as 192.168.1.1, netmask 255.255.255.0, gateway I wasn't sure but I set as my IP on eth0 isp supplied. DNS wasn't sure, just left blank.
But I can't even enable eth1 to test those settings.
then with gui firewall crap disabled I wrote my own iptables ruleset: (kernel flagged for ip forwarding) with all chain policies set to allow.
Code: iptables -A INPUT -i lo -j ACCEPT iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -j DROP iptables -t nat -A POSTROUTING --out-interface eth0 -j MASQUERADE iptables -A FORWARD --in-interface eth1 -j ACCEPT And on the slackware box (ethernet switched btw) I set up static IP 192.168.1.100 w/ eth1 on fedora as gateway.
But like I said, fedora refuses to enable eth1. Been reading and googling last night and all morn.
(p.s. gnome, but all the tools are confusing the crap outta me, They seem to work against each other. I'm used to just bash.)
I have a bit of a silly question, as I should know better, but I have a Toshiba A200 laptop that wasn't working well with the default ath5k driver so I switched to madwifi. It works great, but after the laptop goes into suspend or reboots, the driver doesn't get loaded and wireless isn't available.
I've been working around this by going to proprietary drivers, which shows the madwifi driver. When I say activate, it comes back with a failed message but works.
I'd like to save myself from going through this several times a day, but I'm not 100% sure what to do. Do I add madwifi to modprobe or something like that?
I'm Using the latest Kubuntu 10.10 with the default network manager -- which I think it's called Knetwork manager.
I have set up a static IP by adding a new connection using this manager and then clicking it so that it is used to connect. But as soon as there is a computer reboot the connection falls back to the original autoeth0 which has dynamic IP on and which I cannot change or delete.
I have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?
I am running a debian squeeze machine on a ibm t40 laptop with window maker as my window manager. I am using gpointing-device-settings as a program to get the scroll bar on my touch pad working. unfortunately, I can't get the settings to stick after i shutdown and turn on. I have to go into the program and unclick then reclick the button. i'm using version 1.3.2 (ive tried both deb and source versions). does anyone have any ideas on how to fix this? and if there is any configure files that I could configure instead of having to use the gui program.
entries for connecting to broadband. Was OK with ubuntu 8.04 which had boxes for DNS server, etc. The 10.04 asks for MAC address (?) and there is a space for "DHCP client ID". I don't understand these terms. how I may proceed, especially exact syntax for any command line work. I am in Chennai/Madras, and have a BSNL wired broadband connection to my Dell laptop.
I bought Sony vivo c series laptop and I tried to install ubuntu 10.10 version on it.After installed ubuntu the ethernet device was not activated. But It's working fine with wireless network. Similar problem I faced with older version 10.04 also.
Then, I tried with newer version 11.04. It detected Ethernet device.After installation over I just rebooted and I have chosen ubuntu OS, then it stuck and goes to blank screen.I am doing all my work in ubuntu only, i am struggling to recover form this problem for a long time.

I'm having network problems and I have no idea how to fix it. At first, my internet connection was suffering on all computers on my network (Mac, Windows and Ubuntu 11,04). So, I disconnected my cable-modem and then reconnected. Nothing.... So, I rebooted my Windows machine and the internet came back on that computer.
I then went to my Ubuntu computer and clicked on "auto eth0" (per the way I interpreted instructions from the internet). The symbol turned from the "two arrows" to what looks like a wireless, looking for a signal. I thought that maybe I should just reboot, as I did with Windows. However, when I did reboot, that same wireless symbol was there, then a message came up saying:
Code: Wired Network: You are now disconnected I can't seem to get my internet connection back on my Ubuntu computer, though it is working on every other computer on my network.
i installed linux at home on my laptop (dv2000, hp). Because i was having problems connecting to the internet through wireless. And wired at friends houses.So installed linux. Wireless took me a while but finally got that working. Now the problem i have is that wired is not working apart from at home. Any other router apart from mine it cannot connect to.
