Ubuntu Networking :: Network Doesn't Auto-connect At Startup
Jan 5, 2010
I have a Broadcom 4312 wireless chip. I have use the STA drivers that Ubuntu recommends. I can connect quite easily just by clicking on the icon, so this is more than a niggle than a problem.
My network isn't protected as we live in the middle of nowhere (quite literally) and network theft isn't a problem. We also run a self-catering cottage, and let guests have free access to our network anyway, so it is easier for guests to access our network without me having to give them all the key. When I did use wpa, it would start itself up with the laptop, so I kind of know that this might be the cause. Is there any way I can fix it without encrypting the network?

I have noticed that a common issue to several distros is the fact that the networking subsystem doesn't automatically detect the link if an ethernet connection is disconnected and then re-connected to the NIC after boot. If the ethernet cable is connected after the system is up and running, nothing happens - ethtool eth0 shows link detected: no, and you have to restart the network service to let the NIC know that there is in fact a link, and actually connect. I have a Fedora14 (KDE) box with a brand new Asus motherboard with embedded NIC. Everything works great except the auto-detect of a freshly connected ethernet connection if the link is down to begin with.
Am I missing a ethernet link sentinel utility or something, or is this just the way linux works? I have done plenty of research on plenty of posts, and it seems this is a common problem, with no solution other than manually or programatically restarting the network service in a script to detect the link after a disconnect.

I recently fixed an annoying problem and I thought it would be nice to share my solution here. The problem was that after a cycle of suspend/resume, Network Manager would only auto-connect to the same network as it was previously connected to. So, for example, if I suspended my laptop at home, and then I went to school and resumed it, it would try to connect to the home network, and then just give up. It would not connect to the school network unless I explicitly told it to.irst, I'll describe the fix. If you're having this problem, you can this. Copy the following:
Code:
#!/bin/sh
case "$1" in

I've recently bought a recycled computer for my office. The plan was to get an old cheap computer and use it to write LaTex documents but nothing else. However, I can't seem to get the thing to connect to the internet. I'm on a University network which has a funny setup but I don't think that's the problem.So here's the deal. I have tried this with 9.04, 10.04 and 10.10 and it hasn't worked. The computer recognizes the ethernet cable. If I issue the command "sudo mii-tool eth0" and get back "eth0: negotiated 100baseTx-FD, link ok". However, click on the networking logo on the top right, and click auto eth0, it tries to connect for about 30 seconds, then gives up. Unfortunately I'm pretty clueless when it comes to networking so I have no idea what to do to try to fix this.

Upgraded To Ubuntu 10.04 The Other Day. And when I first installed it everything worked great except for my sound card which I fixed. But there was no problem with connecting to my Router via an Ethernet cable. Then I updated the video card drivers, restarted my PC and it wouldn't connect. It would try over around 1-2 mins then tell me its disconnected. No green light activity on the router / network card either.
I've reinstalled fresh copies of Ubuntu a couple of times now, Hoping to get the default settings back. But nothing has worked since.
I looked around the net and found quite a few people had this problem on previous versions of Ubuntu but it would seem most of there fixes were for there Version, so it hasn't helped me.
Heres some info:
ifconfig:
I've tried all the various things from dhclient to ifup/ifdown etc etc.

I've been trying to get and old PCI wireless card to work on Ubuntu 10.04. The card is a Zonet 1602. It was not recognized automatically.
I have been able to get it to work using ndiswrapper except that when the computer is started it does not automatically connect to the network. I can click on the network icon and select my network from a list and it will connect, including properly authenticating the network key.
I have worked through a lot of information on the web but much of it seems to apply to earlier versions of Ubuntu and some if it does not match what I'm seeing in 10.04.
There is a built in Ethernet controller on the mother board but I have disabled it in the BIOS.

The auto connect feature of NetworkManager Applet (version 0.7.997) isn't working on my system. If the WiFi connection dies, Network Manager doesn't detect that the connection has been lost and try to reestablish the connection. I have to manually click on the WiFi hotspot to reestablish the connection. This appears to be the case both while the computer is running and when I first boot it up (i.e. when booting, if the first attempt at establishing a WiFi connection doesn't succeed, Network Manager doesn't retry or try another hotspot).Is this "normal" behavior for Network Manager? If not, does anyone know a fix? Here's some more info about my system:
Computer: Dell Inspiron 1318 laptop
WiFi Chip: Broadcomm BCM4238
Kernel Version: 2.6.31.12-174.2.22.fc12.x86_64

I have xbmc, a media center shell that runs on ubuntu. I am trying to set up a laptop to run it and be a full time media center. so far it works great, I installed xbmc live, but the only issue is I have a wep2 protected wireless router and the wifi does not connect automatically.
I have it set up and am using wpa_supplicant once those commands are run the wifi works great.I am a novice in linux in general, and can not seem to get this to work on startup, can anyone point me in the right direction on this? I haven't been able to find the xbmc start up script if one exists, I figured adding those lines to it might work,does this sound like a reasonable approach? if anyone knows where that is and how it is defined to be launched on start-up i would appreciate it(I guess this is getting into the general Linux knowledge but still good info)

I have a wireless network adapter that I finally got working with Ubuntu 10.04, but now I have a question. Is it possible for the network adapter to connect to my network at startup, rather than waiting for NetworkManager to do it?I was able to do this in 9.04, but since Ubuntu started using upstart.

recently I risked a look to the Linux world and I'm happy so far, but now I've got a Problem, I'm unable to solve by myself. I installed Mint (Julia) on my old Laptop to test Linux. The Laptop has a very old PCMCIA WLAN Card with a Realtek rtl8180 chipset. Everything seems to run perfectly so far with one exception: the WLAN doesn't find any Network to connect although the card and the driver seem to be installed correctly.
Here some code from the terminal:
Code:

I have installed WvDial (apparently) but it has no icon or launcher to start it by default, how do i get it to run? I also need basic set up how to. I am running Ubuntu 9.10 (Karmic) and network manager doesn't seem to be able to use my modem to connect to the internet (set up wizard works, appears connected, but then I get page not found error). Hence I wish to use WvDial to try to connect instead.

i'm experiencing some weird behaviour: I have a server running ubuntu 10.04 and two Apple laptops in my home network. Sometimes after booting up the server doesn't connect to the wireless network, but instead "kills" the connection of the laptops. (The network then isn't available for about two minutes - it's showing but it can't connect) On the server the network interface is up, but not associated.
Sometimes the interface isn't configured properly (iwconfig isn't showing an entry) - but in this case the behaviour obviously isn't showing. some information about my system:
Ubuntu Version: Server 10.04x64
Wireless Card: Netgear WG311v3 with marvell chipset
Driver: ndiswrapper+mrv8335x64

This is on Lucid, using a Dell Mini. I installed the required packages for a USB tether to my iPhone. Network Manager recognized it immediately as wwan0, but it doesn't connect. Also, it never asks me for the password to connect to the Personal Hotspot (as it does when I can connect from Windows).

If I made a distro from scratch it would have been Lubuntu, cept I'm sure my theming would have been horrible. Now Ive installed on a couple of my Laptops, and even had a few friends convert, and for the most part everything is hunkus doris, cept one small issue thats keeping me from slapping it on my trusty laptop. I'm lost as to what the problem could be. Ive tried just about all I can think of, but I use sprint mobile broadband to connect to the net and then use Network Manager to share this connection with the laptops and Palmtops around the house. I can get my sprint modem to connect thats not a big problem the problem is now I cannot get the Auto Eth0 to connect to send out as a share. It just refuses to connect. Now this is not a Lubuntu problem at all Im sure its somehow a Lxde problem, as Mint Lxde, PeppermintOS, and so on do the same thing, refusing to connect Auto Eth0 while Sprint is connected. Any Gnome based distro this works flawless, as does Xfce distros, so Im sure this is somehow something within Lxde. Im sure its down to just "missing" a file or some stupid overlooked thing.

I have edited my /etc/fstab file in order to have it automatically mount a windows network share at startup.
The problem is, that it isn't really working during startup. After I log in, in order to make it mount I have to open the terminal and enter "mount -a".
The following is my fstab file:
Code:
I suspect this has something to do with my laptop not having made a network connection when the entries are mounted, but I'm not sure. How would I go about finding out about any errors?

I am relatively new at Linux and am having some problems with an install of openSUSE 11.2. I installed 11.2 on my Thinkpad X31 dual boot with WinXP. It seems to work very well except the network. I looked up swerdna's instructions on setting network cards up. I used YaST to try and set the system up as described in swerdna's instructions. Everything looks fine my network card and wireless card show up in the overview settings screen and everything sets up fine. But when I exit YaST the network doest show up no icon in the system tray and it doesn't even try to connect.
I did go into hardware to see if it was identifying my hardware and my network card shows up as "Thinkpad R40" and the wireless shows up as Cisco Aironet Wireless 802.11b. As far as I know this is correct. I have tried three other distro's and this one has gotten the closest to working so far.

I have searched for an advanced network mangager, like the one available for Nokia's Maemo with no luck.
I want to automatic connect my x200 laptop to a VPN connection When I am home on my LAN (eth0) and when I am using certain Wireless networks.
I don't want to use my VNC connection everytime I connect to the internet, just on these networks, so I wont mark the checkbox in the vpn settings.

I am running 11.04 and have a netgear USB wireless NIC. When I am logged in I can connect to the wireless network through the USB adapter without any problems.I wish to use the machine as a part time home server and so have installed samba, LAMP etc however when I start the machine the NIC is not activated until I have logged in.
In the past I have done this but only ever over a wired ethernet connection, never wireless? Can some one please point me in the right direction?

I recently installed 32bit maverick and wanted to make it login automatically. I tried enabling auto login from Admin > Login but that didnt work and I was still prompted for my password. Then I went to Users & Groups and changed the password option to Do Not ask for password at login now after I reboot, the user list is shown (only 1 user) and it doesnt ask for password after I click on my username.
However, then it gives a few errors (as i vaguely recall):
1. cannot load .ICE directory in my home directory
2. some error 256 about a gconf-sanity-2 file
3. nautilus cannot load my home directory etc
and then it gets stuck without loading anything (blank wallpaper). i ve tried navigating to my home directory using Alt F2, gksudo nautilus and my home dir contents are encrypted by the ecryptfs (there is a readme.txt file and a shortcut). i have tried to decrypt but it doesnt work... i ve also tried to start/stop gdm, and startx but nothing works. if i stop gdm, then the prompt doesnt recognize my password and keeps on rejecting the commands i enter... I think this has something to do with the home dir not being decrypted due to the dont ask for paswd option... how can i disable the dont ask for pwd without the gui (i can access my / by booting through an external usb).

Im using a Samsung R420/R470 laptop with Broadcom bluetooth and a Prolink PMO624B mouse.My mouse works when I add it as a new device, but if I off the mouse and on it again, the mouse does not auto connect. I have to press and hold the connection button under the mouse and reconnect to the mouse.The mouse says that it is linux compatible, so I guess its a problem with my bluetooth drivers.

I'd like to know how to configure Fedora 14 so my VPN connects and reconnects itself automatically, since the "connect automatically" thing I checked in the network manager doesn't work.Is there a way to make sure that everything uses the VPN, so when for some reason the VPN is disconnected the applications will wait for the VPN to reconnect itself instead of switching to the regular network ?Also since it's pptp VPN I tried to disable Ipv6 but I don't know how to check if I successfully did it, can you guys give me the command line to check that ?

I have installed ubuntu 32 bit version on my HCL netbook. I use reliance netconnect (Huwai EC 1260 or 168c). I have configured it and it works well. But the only problem is that I have to connect the netconnect device before booting. If I connect it when its ON, the networkmanager does not connect automatically. even on the right on the tray icon, enable mobile broadband option is not there.
