Debian Configuration :: NetworkManager Doesn't Show (working) Internet Connection / Sort It?
May 14, 2010
I have no idea how I managed this, but I am able to connect to the internet but NetworkManager doesn't show any connection. This means that until I kill it, I cannot log in with Pidgin, because it is waiting for a connection.
Do I disable NetworkManager completely or do I try to make it recognize that I am connected to the Internet? If the latter, then how should I go about? (Please let me know which files I need to show you, because I know I've messed around with a couple).
I have recently bought a branded Onda MT835UP USB broadband modem. The hardware comes with its own drivers/GUI for linux, however I'd rather use the Debian-provided NetworkManager+modemmanager packages.
A few details:
- I'm using debian unstable, - latest NetworkManager 0.8.2-3 from experimental - latest modemmanager 0.4+git$foo from testing - latest usb_modeswitch[_data] from experimental
1 linksys router: gets the net from PPPOE and give the network DHCP. The router IP is 192.168.1.1. 1 windows laptop that work wireless and wired. 1 debian desktop that work wired and not working wireless. THe problem with the debian desktop is like this: I have a TP-Link TL-WN321G installed and found by lsusb command. I make a wireless connection WPA Personal (just like the router settings) it says i am connected to the wl network but no internet connection. the route command give me this:
[code]....
I tryed with wicd who said that the connection is WEP (and it's not, it is setup to WPA on the router and the network-manager conncetion) and when i try to connect i get bad password. I tryed with network-manager uninstalled and no chance.
Having some memory loss i think (in my head not my pc). I have set up apache before , then changed to dsl in the last week and cant seem to get this new modem/router to work. i can get the loopback address to work, as well as the network ip. can NOT get my other machines to hit the server on the network . also no connection from outside the network from port 80. my modem is a motorola (att) ,apache2 on my toshiba laptop, amd x2, 3gigs ram.
I just freshly installed Jessie on my Dell Inspiron 5110, I configured the network on the installer and had no problem. I can browse the web, get updates and install software.
But I can't find new networks. It just show "No Networks".
lspci -vnn Code: Select all09:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] [8086:008a] (rev 34) Â Â Subsystem: Intel Corporation Centrino Wireless-N 1030 BGN [8086:5325] Â Â Flags: bus master, fast devsel, latency 0, IRQ 55 Â Â Memory at f7e00000 (64-bit, non-prefetchable) [size=8K]
I just got myself a Dell Inspiron 1440. And decided to install my favorite distro Debian. I got the installation to go with no issue and all seems to be working fine. However the wireless isn't working. NetworkManager doesnt even detect a wireless card. I followed the instructions here and installed the b43-fwcutter and then issued the modprobe b43 and modprobe b43legacy commands. Then I issued the iwconfig command and this was the output.

Also, I've been doing some research and found out about some file located /etc/udev/rules.d/70-persistent-net.rules. So I looked in mine and found out that only my eth0 is added.
I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list
Code: Select allroot@i67svof:/var/www# ifconfig venet0Â Â Link encap:UNSPECÂ HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00Â Â Â Â Â Â UP BROADCAST POINTOPOINT RUNNING NOARPÂ MTU:1500Â Metric:1 Â Â Â Â Â RX packets:557 errors:0 dropped:0 overruns:0 frame:0 Â Â Â Â Â TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 Â Â Â Â Â collisions:0 txqueuelen:0 Â Â Â Â Â RX bytes:36463 (35.6 KiB)Â TX bytes:0 (0.0 B)
My HWaddr doesn't look that well :) 'ip addr' prints this result:

These are the last lines in /var/log/syslog:

And finally my network config in /etc/network/interfaces
Code: Select all# Auto generated lo interface auto lo iface lo inet loopback # Auto generated venet0 interface auto venet0
I downloaded banshee because i knew that could put movies on my ipod, but everytime i run banshee my ipod doesn't show up. i tried started it, then plugging it in and still didnt show up. Anyone knows what the problem is?
I am using Empathy IM client to access to gadu gadu and to message with my friends. The strange thing that is happening is that I keep on being connected and then disconnected and then connected again even if I am continuously connected to my internet connection (no problem when surfing or using skype for example)It also seems to come only from me because when my girlfriend is using the same gadu gadu on her windows laptop simultaneously, she doesn´t get disconnected (whether when she is at home and using the same connection as I am or when she is outside, meaning that it doesn´t seem to come from the whole gadu gadu network)maybe it has something to do with the ports that gadu gadu is using but it is strange that sometimes it is working for a period of time and then not and then again.
I have just installed Debian Squeeze on my spare computer (dual booted with Ubuntu 11.04) and I cannot connect to the internet using Squeeze. Due to my ISP, I have to manually connect this computer and on Ubuntu copying and pasting a text file such as this into the terminal works with no problems.What do I need to do to manually configure my Squeeze internet connection?
I replaced my motherboard and processor but am keeping my old hard drive without reformatting it. Things work well except that I cannot connect to the internet. I am thinking that I just need to reconfigure the connection to see the new network hardware. I tried /etc/init.d/networking restart but that doesn't do anything. What am I missing? By the way it is a wired connection - not wireless.
AMD 64 Upgrade to testing last night killed my internet connection. The lan works, I can ping the dns server from my IP, however no mail, browser possible. Is something in testing broken again?
i'm realatively new to linux am just getting my head around the command line, any way my problem today is, my network connection and networkmanger program have been deleted/uninstalled after i did a system update. im running ubuntu 10.04 32 bit. I have run of some commands which should be able to tell you whats going on. at the moment i'm using a live ubuntu cd to gain net access.
so the question is How do i restore my network connection and get my networkmanager program back without a internet connection. (i can download stuff to a memory stick and do manual install) Hope someone can shed some light on this, i know this topic has been covered before although each case seems slightly different to mine.
I'm going to start using Debian as my desktop system rather than Ubuntu since I'm not really liking all the crazy eye candy and just wanted a fast and simple system. My main problem is networking, I guess I'll start off with my system specs and other information for problem solving.
I have a Realtek RTL8111/8168B Ethernet Adapter builtin to my motherboad which I am using, I could only get a basic connection, by basic I mean that it allowed me to connect to my local area network but not the internet. I then modified /etc/NetworkManager/NetworkManager.conf to change to managed=true this allowed me to use the internet, but the problem is, that it is a very unstable connection, the speed is very slow and it drops a lot! I have to carry on running /etc/init.d/network-manager restart twice to get my connection back, which lasts for about a minute.
About an hour ago i did an update on my Debian Squeeze. After the update was completed my LAN connection stopped working.. now i have to connect my computer to my router with a usb cable instead with my ethernet cable.. also, on the network connection, on the wired network section it says that the device(ethernet) has not been managed..
am not able to get internet working, am using debian testing. Dunno what is the issue. Here's the lowdown on /etc/network/interfaces :-
Code: Select all# This file describes the network interfaces available on your system# and how to activate them. For more information see interfaces (8)
#The loopback network interface auto lo iface lo inet loopback
auto eth0 allow-hotplug eth0 iface eth0 inet dhcp
I tried all the usual :- Code: Select all$ sudo dhclient (this usually worked/works) $ sudo ethtool eth0 $ sudo systemctl restart networking
I recently installed Fedora 15 x86_64 on my new AMD Machine and I'm quite pleased with things thus far.Here's where my problem comes. I mainly bought that machine to help me with Development. More specifically, Virtual Machines for testing purposes. I have installed Fedora 15 x86_64 as a qemu-kvm Virtual Machine and it's working.. for the most part. I am having a whole lot of trouble getting it to connect to the Internet.
My guess is the only way I'm going to reliably do that is to setup a Bridge. Yes/no? However, in order to setup a Bridge I need to disable NetworkManager and that where the fun happens. It completely disables my network connection. I'm probably missing something small, but I can't figure out what I'm missing. I've double checked my ifcfg-em1 multiple times(I've been trying for ~24 hours so far) and all the settings are as they should be.
I've turned NetworkManager off and stopped it(chkconfig and service) and turned network on(chkconfig and service). Theoretically I should simply need to turn off NM and turn on network and things should be fine. no?
I just installed Linux for the first time and I'm having some internet connection issues. I am running Linux Mint 9 on my HP 210 netbook. I am unable to connect to anything using NetworkManager 0.8's automatic configuration. I can't even ping my other computer. Both computers are connected to my cable modem by a switch. The other computer (the one I'm on right now) is running Windows Vista and is working fine.
eth0 is getting an IPv6 address assigned to it, but no IPv4 address. When I do dhclient (I'll include it at the bottom) it says no DHCPOFFERS received and then makes another adapter called eth0:avahi with an IP of 169.254.9.78, which I think I understand from what I read is just a default.
I noticed when I looked at the ipconfig results from my Windows computer that there were a number of things called tunnels on there. My ISP is cox, and I saw some other people with cox had the same setup. One of the tunnels seems to make it so IPv4 and 6 can coexist. Could that be a problem? When I asked Cox why it was set up that way they helpfully referred me to wikipedia.
Here are my ipconfig (from windows), ifconfig, and dhclient results. Let me know if I can provide any other information.

I just installed the lastest stable Debian (gnome) today and what I was most afraid just happened: my laptop's wifi isn't working properly, it isn't turning on. This had already hapened on livecd.
In the laptop's chassis leds, the wifi led apears as green. When I click to turn on the wifi, as shown on the picture the button, quickly disappears and appears again not seeming to have any effect at all at turning on the wifi but not showing any error either!
Picture :
What's interesting about the wifi not working is that in the installation process I was able to connect to a wifi hotspot and it connected to the internet fine!
Now after installation was complete and my system did the reboot, I was no longer able to connect to the internet using wifi.
My wireless card is Atheros AR9565 and my LAN card is also Atheros.
Here is an output of lspci and lsmod which may have some leads about the problem.
When I connect my Debian PC to my WiFi router my PC doesn't get internet if other devices are connected to it .
When i disconnect those devices and connect my Debian PC only then my PC connects to internet but other devices connected to it later do not get inernet connection.
When I connect my Debian PC using LAN Cable to the same router all devices work fine.
I manage to install debian on my flex 10 (lenovo), but now internet is not working, i can see the network, but even being able to connect to them i can't access the net...
I was not connecting to Internet in kde so i edited auto etho settings i make some changes
but alas! no Internet connection
and the worse thing is that i lost connection in gnome desktop too
but it is showing me i am connected to Internet but i cannot surf (server not found))
{i changed the setting to default {{after i changed them in kde ]]
and notice following
in edit auto etho connection connect Internet automatically-yes
ipv4 setting-- automatic (dhcp)addressees nonly
ipv6 setting
ignore
so ubuntu is showing me that i am connected to Internet but i cannot access Internet
so the main problem is ""ubuntu is showing that i am connected to Internet but my browser says no server found and i can not install software in software center it gives me error --please check you Internet connection
I am using Linux operating system fedora 6 .Before today everything is going well. But today internet connection gets failed. It can not connect to the server for the internet connection. But in the same computer,installed windows operating system shows the internet connection.Please try to answer my question why the Linux operating system can not connect to the internet?
I had some trouble with the netinst CD and I had to install lenny with the 6DVDs instead. My internet connection only works after I edit the interfaces and resolv.conf files manually. So my question is: can I do that from the netinst CD before it actually needs the connection to install everything? (otherwise I'll just need to use the DVDs.
I have an OpenVPN connection set up in the NetworkManager, and it works fine when I click on it to activate it. I would like to have it start at login, and I cannot find a way to get it running automatically at login, just after I connect to the local network.
I have little problem with NetworkManager. This problem begin when I upgraded Debian Etch to Lenny.
When I right-clicked nm-applet in Debian Etch, I get this dropdown menu where was button "Edit Connections..." Now in Lenny there is only "Edit Wireless Connections" button. So I can't edit my wired connections anymore.
I know I can just edit /etc/network/interfaces file to set my IP, but I need about 20 different IP:s at work, so that is just stupid do it that way...
I have Fedora 12 and Windows 7 in a dual boot configuration in my lenovo laptop.The config of my laptop is core2duo 1.73, 3gb ram and 160gb hdd.I updated my fedora 12 yesterday.
