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?
View 4 RepliesHave searched for this and am sure the answer is out there somewhere, but I can't find it. My wired network is configured as AUTO, and is DHCP, I can add a new static config, but can't get it to load, as the original AUTO always loads on a reboot. I need to be able to run sudo Network manager so I can reconfigure the default..
View 9 Replies View RelatedI have 2 workstations that I'm trying to network together so that I can backup each to the other. One is XP sp2 and the other Fedora 9. Since installing Samba on the Fedora box and trying to get it configured, I have a problem that Add/remove programs won't do installs because it says there's no connection to a network. Network Manager says there aren't any connections, but it worked before the Samba install. Mozilla and Thunderbird can access the internet OK. Both workstations are connected by cable to my router and thus to my ISP (DNS server).
Two questions:- where can I find hints on setting up a wired connection (which card's MAC address does it want? router or wrkstn?) and Am I right that Add/remove is stuffed because of Network Manager?I now have Samba working from Linux to XP, but still can't get into Linux from XP. I tried the Linux PC's MAC address and set up a wired connection in Network Manager. NM still thinks there isn't one...
I've been struggling with this a bit now, and I'm not sure what the problem is. I have a laptop with a BCM4401 Ethernet card as well as a BCM4311 Wireless card. The wireless card works great out of the box, I'm able to connect with it perfectly. The problem is the ethernet card. Here is the situation: The NetworkManager menu doesn't list "Wired Networks" at all (ie. it doesn't say "not managed", it just only lists Wireless networks) Going into Network Connections, there is an "Auto eth0" entry ifconfig shows eth0 (which I assume means NetworkManager isn't managing eth0) I have edited /etc/NetworkManager/nm-system-settings.conf to say managed=true I have edited /etc/network/interfaces to remove any mention of eth0 (all that's left is the "lo" lines) So I'm not sure why eth0 is still showing up when I run ifconfig, and why Network Manager is not managing it. Any ideas?
Edit: Not sure what I did but now ifconfig spits out this:
Code:
eth0 Link encap:Ethernet HWaddr 00:1c:26:2c:60:75
inet addr:10.0.1.12 Bcast:10.0.1.255 Mask:255.255.255.0
inet6 addr: fe80::21c:26ff:fe2c:6075/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[Code]...
The MAC address of the "Auto eth0" entry is 00:1C:23:8F:D4:39, the same as the eth1 entry that ifconfig spits out.
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 am a Windows refugee who discovered Ubuntu as a way to save my files from my virus-ravaged computer. Had no installation discs for Windows, so when I had to wipe my hard drive and start over, I decided to give Ubuntu a try. I've had mixed success, but that's another post...
Right now, the problem is that I installed 10.10 two weeks ago and was able to connect to the Internet with no problems - until yesterday. Suddenly, our wireless network (the only one in the vicinity) does not come up as available in Network Manager. In fact, the entire wireless option disappeared. I know there are many posts and threads on here about this, but weeding through them trying to find an answer is more frustrating than actually dealing with the problem. I know the router works because I can post on this forum from the Macbook. I really like Ubuntu and would like to keep using it, but not being able to connect to the Internet now on top of the other issues I've had is making me doubt I want to continue down this Linux road.
P.S. When I attempted an analysis through System Testing, it said something about there being no proprietary drivers?
I have used ubuntu in the past but had a lot of hardware issues with it and unfortunately moved back to windows (( BUT i have tried Ubuntu again and all seems to work great except wifi My wifi connection is sort of working because when i run SUDO IWLIST SCAN it does pull up all available networks. But in the network manager icon on the panel i left click but i see no networks and can't connect to anything. I WOULD LOVE TO keep Ubuntu and use it permanently but I must get wifi working or else this won't be possible.
View 4 Replies View RelatedI recently put Linux on a Thinkpad T40 I got. The wireless card works out of the box--I can see nearby networks. However, I can't connect to mine. network-manager would try (spin spin spin), fail, ask for the password, and then go back to the beginning and repeat indefinitely. This happened to me on a different computer, and on that one all I had to do was use wicd instead of network-manager. So I installed wicd, but it's not working either--it hangs at "Obtaining IP address".
I've found many, many threads with people who had the same problem, but none of their fixed worked for me.
I also tried to get wifi going manually, using this guide, but that didn't work.
My wifi connection drops sometimes and, for some reason, Network Manager attempts to connect to my neighbor's network, which requires a password (which I don't know). Is there any way to blacklist a wireless network so that the Network Manager will never attempt to connect to it?
View 4 Replies View RelatedI had trouble connecting to a wireless network with openSUSE, so I tried the YAST network manager to see if that fixed it. Not only did it not fix it, but now I cannot connect to any network, wired or wireless. I tried to open the default network manager and it said "Network management disabled". How do I re-enable it?I also have set YAST settings back to their originals with no luck.
View 7 Replies View RelatedI'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.

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.

I'm really in newbie category, and not comfortable with computer or internet jargon. I can still connect with ubuntu 8.04 and firefox, just once daily. In a later post I also added: In Ubuntu 8.04 there was a system> admin> network tab (missing in 10.04). In the connections tab "wired" was checked. The general tab had my computer name (tsq-laptop) for host, and a blank box for domain name. The DNS tab had 192.168.1.1 in the servers box (presumably my service provider BSNL), and nothing in search domains. The hosts tab had a list of IP addresses and aliases, the first few being:
127.0.0.1 - local host
127.0.1.1 - tsq-laptop
::1 - ip6 local host ip6 loopback
fe00:: - ip6 localnet, .... (and a few more such I think most (or all) of these entries were generated automatically by the system, since I don't understand the jargon at all! I don't recall having any difficulties then, some two years back.Before that I had major problems in using the internal modem for a dial-up connection, but got detailed help by e-mail/internet from some really knowledgeable people in Europe and elsewhere regarding linmodem configuration, which I followed blindly and it worked!
In 10.04 there is only the taskbar icon to edit settings, and it has a different structure. It asks for MAC address (example 00.11.22.33.44.55). Other info required is IPv4 settings, DHCP client ID, about routers and other stuff. There may be other system settings to be made, which I can try with proper guidance. The ubuntu help page gives very sketchy information, and the images are not clear at all. No response to that till second day. Subsequently: In the 'wired' tab the 'routes' button popped a table where I entered address as 127.0.0.1, and netmask as 255.0.0.0, leaving gateway and metric blank. This is all geek stuff for me - I'm an old-fashioned engineer from the slide-rule era!
Should all this have been in the newbie forum? Thanks, =TeeSquare=

I just installed (dual-boot with Vista) Ubuntu 9.10 in my Toshiba Satellite M300. The problem is that (when using Ubuntu 9.10), its network is dead, both wireless and wired.

Wireless router <=========> Laptop <-----> Switch <-----> PS3

Both laptop and ps3 have static ip addresses
The reason for this is I can connect to the internet on my ps3 through my laptop, and I can stream from my laptop to ps3 through wired connection. This works fine in windows 7 all I had to do was right click bridge connections. As I dual boot I don't want to have to make any changes to the settings on the ps3.
My interfaces are:
eth0 - wired
wlan0 - wireless
I installed bridge-utils and created a bridge and added both eth0 and wlan0 to it. However I could not get it to work. I have also tried internet sharing through network manager and firestarter.

I use Ubuntu 10.04. Last night, I installed the most recent updates for this istribution, and before I shut off my laptop, my internet was working smoothly. However, today my Internet connection is behaving very strange. When I try to connect to the internet, my browser times out or cannot establish a connection. I'm able to connect to low-input sites like Google search, but I cannot connect to sites like Facebook, Wikipedia, or even the Ubuntu forums (I'm currently using a friend's laptop to post this). Pidgin and Skype work without a problem, as well as Transmission. I primarily use Firefox, but I also tried Chrome, Opera, and Epiphany; none of them worked. Oddly enough, my update manager also cannot connect to the Internet to retrieve updates.
I have restarted my router, but it still works properly, as it is running fine on my friend's laptop. I have tried 'no proxy' in Firefox, but it did not help. I also disabled IPv6 in etc/sysctl.conf by adding the code:
#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
[code]....
I just finished installing Ubuntu 10.10 64bit. During installation Ubuntu was connected to the network and was downloading updates. After rebooting though, it cannot connect to the network.
