I just installed ubuntu 8.10 on my pc. Before was XP installed. I formatted the system and installed ubuntu. Installation was successful. Problem is that I cant connect to network. My network card: realtek 8139 ethernet card
On ifconfig I get:

Also the connection is wired one with modem only it's reliance broadband. The wire is connected between modem and pc but there is no blinking of light for this connection. The wan is active and wan's light is blinking and when I was on xp on same pc there was no such problem.
connect to wired LAN in ubuntu 10.04? I think I have specified the IP address and everything correctly. But it says no connectivity. In windows it says connected but I am unable to open any webpage.
View 2 Replies View RelatedI have an Ubuntu box, 11.04 x64, running on a Dual Opteron SFF box (iWill ZMaxDP... pretty old machine). Up until a few weeks ago, it was acting as a Windows 2008 Server, but i moved it to Ubuntu.
Anyway, the machine will not stay on the network for any amount of time, without falling off... I have changed network cards, cables, ports on the switch, etc, and nothing seems to work. I have a Windows 2003 box giving out DHCP addresses, and for a while, i actually tured that off and setup a second Ubuntu box to give IPs... it made no difference. The box gets an IP, and can ping outside for a bit (2 min or so) and then just looses connectivity... ifconfig shows it with an IP (i have tried both Static and DHCP config) and nothing seems to work...

I am trying to Setup citrix ICA client 9 on Ubuntu 9.04 Server. I installed it very easily and I am not getting any lib error also. But when I try to connect to the citrix server, it fails with a pop up saying "Error in Network Connection Network or Dialup connection may be preventing ......" This is driving me crazy from 3 days. My project is to check the feasiblity of a Linux desktop

I am unable to get my wired network connection to work. My laptop sees the wired connection, but will not connect. I am running 10.04 on aLenovo T400 with 3 gb of ram.
View 7 Replies View RelatedI 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.)
View 1 Replies View RelatedOkay, a couple of weeks ago I was running 10.04, got an auto update that needed a firefox restart, so rather than restart, I just shutdown the computer for the weekend. When I booted the computer on Monday it would find sites (www.google.com, start.ubuntu.com) but it wouldn't download the necessary items to load the page. Now I have a windows laptop sitting next to the ubuntu box and it was online with no issues, so I know it wasn't the connection itself. So I decided that the update messed up the system so I downloaded 10.10 and installed that and ran that all last week.
On Friday I got a system update that required a firefox restart, so I ran firefox for the day and decided that since it was friday, I would just shutdown the computer and reboot on Monday.Well now Monday is here and now I again have sloooowww internet, to the point that URL.. times out and won't come up. I have tried doing a traceroute on both machines and the windows box gets all the way to www.google.com, but the ubuntu box gets about halfway there and then gets no response. I am at a loss, I don't want to reinstall every week. I did try to reboot and run the previous version of 10.10 that shows in the boot menu, but that does the same thing. One thing I did notice is that the broadcast ip is different than the machine IP, don't know enough to know if this is a problem.
I've just installed 11.04 Natty on an old Laptop (Dell Lattitude C400) and am unable to connect to my home network (wired LAN connection, no wireless). The laptop previously had WinXP installed and was able to connect (I have also double checked the cables and ports and they're all functioning ok).

As a random thought I purged the firmware-realtek package and rebooted. Ethernet works fine now??
Fresh Jessie installed this morning with KDE. Wired worked fine during installation and initial boot. Reboot after package installation and only wireless is working right now. I did install the realtek firmware as part of my normal package list.
This is /var/log/syslog when it stopped working, and hasn't reconnected since. Cable is fine as it was working perfectly with a live Ubuntu shortly before I installed the system with Debian.

Opensuse 11.2 - wired internet connection
I keep losing internet connectivity from within OpenSuse. I've had ubuntu/kubuntu beforeand never had a problem. I installed opensuse and now after a few minutes of browsing I'll lose my internet connection.I also dual boot into winXP without any problems.I noticed that when the connection is lost I can't even reach my router - which is where I'm getting the wired connection from.So it's not just the outside internet but the local network too. It only happens within opensuse.
I'm trying to set up a wireless or wired network (wireless would be better...) to share my connection with my housemate, as well as with some devices. The only guide I found regarding this (I must admit, I didn't have much time to put into research), was dating back to 2005, and although doable, seemed somewhat confusing. Getting to the point: is there a way (maybe a standalone program, or some kind of plugin) to share a connection?

After google around, seems like this is a common problem? Then I switched to wired network, and turned out the same thing happens again. Looks like doesn't matter wired or wireless, it kept dropping itself from time to time.
fter checking syslog, I found something interesting...it kept complain eth0 is invalid, then it said it found a better connection?I found that extremely weird..

I've installed F10 on my laptop since few days and I'm facing an annoying networking issue: the network connection seems to work well when, suddently, it goes down for a while, and then come back.This happens with both wired and wireless (Intel PRO/ Wireless 3945ABG) connection.

When it resets it re-negotiates the link speed and I often end up with a 10Mb/s link and on some occasions a 100Mb/s. The configured speed for the link is 1000Mb/s full duplex using a preup ethtool command. I do not use NetworkManager but have the interface configured in /etc/network/interfaces.

I 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...
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.

They seem to be the same. Am I missing something ?
In the right upper corner of your screen,you can see if you have a network connection or not.Most of the time I do not have one according to Networkmanager (?).So I have to enable my wired connection manually.I already tried a lot to change my settings so I would have a network connection at boot,but it doesn't seem to work....Firefox is in Offline modus when I logon..

In computer with windows , i used putty connect to computer with ubuntu, but i can't connect. I don't understand what's error.
In the Putty , i configured:

This is error: "Network Error: Software caused connection abort"
In computer with windows, i can ping computer with ubuntu and in computer with ubuntu i can ping computer with windows.
The situation: The office has a WiFi network on one DSL line, which is used for our VoIP call center, and a wired network for our internal network and the majority of web surfing/traffic . Part of the office must be temperature controlled/monitored - we have a rather nice digital thermometer which is WiFi enabled.I have a Debian Wheezy box with a WiFi card and ethernet connection
What I'm trying to accomplish:Connect wifi enabled thermometer to WiFi network so it can automatically send temp updates (currently I have to do it manually via USB)Have the Wheezy box accept the downloaded file then send it to a back up server in the wired network
Side things that may be useful : Prefer to use wired connection for internet and apt and suchWiFi connection will really just be used for connecting to the thermometer
This [URL] .... topic got me thinking that there might be a way to bring the two networks together, but I don't know if that will wreak havoc on things. I know, the Windows and Mac OS don't like having ethernet and wifi at the same time, might Linux be better for this?
v&n had this to offer in the prior thread [URL] .... which I'll be doing more research on.
i am using ubuntu and with all versions i have one pretty anoying problem. My wired connection sometimes lost connection and i can't reconnect for 3-10min. sometime longer.

Ive recently switched over to AT&T Uverse TV/Internet service and I've noticed that when I ssh into my linux( 2.6.18-194.3.1.el5xen CentOS) server I get disconnected. When I'm using putty it gives the "network error software caused connection abort" error. When I'm at work using one of our jump servers and ssh'ing from the command line it will freeze up from time to time but never disconnects. I think the problem is either with the OS or the new AT&T modem. At first I had my CentOS server using DHCP and it would disconnect within a few minutes after I ssh'ed. I switched over to a static IP and now it goes about 10 minutes before it disconnects. It doesnt matter if I'm actively typing or not, so it's not an inactivity issue. I have the firewall turned off on my laptop, and since the issue happens on multiple devices, including my iphone I dont think thats the issue.
I have iptables and selinux turned off/disabled so thats not it. In putty I have enabled Keep Alive(30 seconds) and it still disconnects. I opened the port on the modem to allow ssh for the IP of the linux server. Ive also recently reinstalled this server with CentOS so I can't compare with the previous internet provider as I didn't reinstall until after I switched over. BUT previous installs with CentOS 5.2 worked fine with the previous ISP. AT&T Modem is a 2wire 3800HGV-B
I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error:
Authentification has failed.
As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.
(I'm probably going to have my forum account revoked due to excessive usage ) I'm setting a VPN connection on openSUSE 11.2. Using the networking icon on the tray I add a PPTP connection, set it up but I receive a message 'VPN connection failed'. Googling it up I tried changing a setting called 'refuse-eap' to 'yes' but it doesn't seem to work. Here's the result from the log file:
