Ubuntu Networking :: Ethernet Lan Port On The Computer Seems To Not Be Activiating As No Wired Connection Is Recognized
Oct 6, 2010
while my brother was browsing the web on my windows partition he had a blue screen pop up, one of the soft/hardware error ones, not a true BSOD, anyways, ever since my lan port on the computer seems to not be activiating as no wired connection is recognized. The lan port/card is directly attached to the Mother Board, it's a gigabyte motherboard in a self-build computer. I'm just wondering if there's anything I can do to troubleshoot this and see if it is truly a hardware problem or if its something else.
I am running 11.04 on a Dell Inspiron 1501 (the first gen.). I was using my Ethernet port to connect to the internet until about two weeks ago - suddenly the system no longer recognised that port even existed and just kicked me offline. I am able to get online now with a wireless card (replaced the broadcom card, that was a whole different can of worms...).
why my system is unable to connect with the Ethernet port? If I plug in the cable nothing happens.
I've just installed the 64 bit 10.04 onto my new netbook, with ample specs to run the full desktop version rather than the stripped down netbook version. My only problem (at the moment) is that my wired internet connection is not recognized within the operating system, yet while I was downloading/installing Ubuntu it had no problem finding and using the connection then. When I boot into Windows 7 or plug the ethernet cable into my Mac, the connection is established immediately, and no need for manual entering of anything because everything is auto-detected. The really strange thing is I've run Ubuntu off a USB stick and when booting off that the wired connection was immediately recognized after startup.
I have a HP Mini running Ubuntu Desktop 10.04, and I cannot get a wired connection to work. My network card is "Broadcom Corporation BCM4312 802.11b/g (rev 01)", and I have the restricted drivers for the card installed. Wireless works fine, though.
I just installed 10.04 on my new netbook and I am suprised to see that the ethernet is not recognized. When I run
Code:
ifconfig eth0
the result is
Code:
no such device
The machine was working fine before I installed Ubuntu. I am suprised to see this problem as I have already installed it on a few machines without any problem such as this.
Just noticed that auto connection to my wired ethernet is not being established after restarts I'm making. Never recall this in the past. I do get an auto connect when I shutdown and restart. I'm using 10.04 LTS Lucid Lynx.
Also have noticed that nearly every upgrade over the past week or so is calling for restart to complete the upgrade. Can there be any unwanted problems in doing several upgrades over a period of several days before doing the restart? I'd like to think not.
As you can imagine these two issues together are causing some lost time.
I have installed Ubuntu 11.04 using Wubi through Windows 7. It seems to be working but it will not connect to my wired internet connection. It tells me there is no wired connection, when there is. I used sysinfo and its not showing any network adapter or controller. I have a board with nvidia nforce go 430, could it be a driver issue. It works fine in windows though. Tried using a wireless adapter and all is working. But why doesn't the wired ethernet connection work.
i have an embbeded hardware that uses bootp for booting from a Network Managemnt Host (NMH)on the same ethernet. The embedded hardware has both kind of ports i.e ethernet as well as E1/T1. I would like ask, what do i require to establish a communication-link between the embedded hardware and the NMH throuh E1/T1 ports of embedded hardware, so as to make it boot through from E1/T1. Further, NMH possesses only ethernet port. Just to refine my questions i'd like to know what additions do i need to do on my NMH , like may be i have to put an E1/T1 port or is it possible that the E1/T1 port can be directly connected to an ethernet port on the other host.
pardon me if i am not making absolute sense here as my knowledge is limited on Layer 1 and layer 2.
I have just installed ubuntu 10.04 using the wubi installer to dual-boot my machine. Under ubuntu, I am not able to connect to the internet or my router. Everything works fine under windows. I have tried to find relevant information in the forums, but nothing seems to work for me. I have tried disabling ipv6, setting a static ip, but no go. ifconfig shows no IP, dhclient results in no DHCP offers and pinging my router's IP results in Network is Unreachable.
I'm running an up-to-date Fedora 12 machine with the Gnome desktop (meaning with Network Manager). My network connection is a wired ethernet to a switch which then connects to a Netgear router. For some reason, this machine can't renew its leases with DHCP, so NetworkManager deactivates eth0, taking my machine off the network. I have to click Network Manager and enable eth0, which seems to work every time.
How can I fix it? Here are the relevant bits from /var/log/messages showing a failed DHCP request and then the successful renewal.
Code: Aug 1 04:00:08 ironton dhclient[12452]: DHCPREQUEST on eth0 to 192.168.1.1 port 67 Aug 1 04:00:08 ironton dhclient[12452]: DHCPNAK from 192.168.1.1 Aug 1 04:00:08 ironton NetworkManager[1261]: <info> (eth0): DHCPv4 state changed reboot -> expire Aug 1 04:00:08 ironton NetworkManager[1261]: <info> (eth0): device state change: 8 -> 9 (reason 6) Aug 1 04:00:08 ironton NetworkManager[1261]: <info> Marking connection 'System eth0' invalid because IP configuration expired.
I'm fairly sure that this is an Ubuntu issue, as I've tried this on my windows computer with success.I'm running a minecraft server on my laptop, previously over a wireless connection but the data rates were too slow. On a wired connection, however, the server starts up and runs like normal but the port is not open when accessing from the network's public IP. I tested this with canyouseeme(.)org. I can get to it from other computers within the network by using a local IP, which to me seems a little strange as it seems to indicate that the port is open on the PC but somewhere in the router it gets confused due to being wired(?). Obviously I've forwarded the ports on the router (BTHomehub 2.0) with both TCP and UCP (it worked over wireless!). Any suggestions as to what might be causing this? I'm stumped.
My desktop computer, running 11.04 (fresh install) sometimes can't establish a wired Ethernet connection. Sometimes when I boot, it keeps trying to establish, but with no luck. I keep trying to choose "Auto eth0" from the networking menu, but still, it doesn't succeed. If I reboot, it sometimes works. I can't establish a connection about half the times that I boot.
The computer is connected with a cable to a router ("Belkin Wireless Pre-N router"), and the router is connected with a cable to a cable modem.I've been using Ubuntu for a while, and I've had a problem for the past few versions (since around 10.04)? I thought that it might be some old issue that got resolved, so I did a fresh install of 11.04 today, and still have the same behaviorI'm willing to try things next time I can't get a connection, but don't know what.
I'm currently running Fedora 13, after I updated the kernel to 2.6.34, I have to run (as a superuser) "service NetworkManager start" in order to start my network manager, is there are way I can run this on startup?
Also my ethernet connection seems to only work when I restart/boot up my computer, when I wake my computer up from being asleep, the ethernet stops working.
I just installed wubi, and it looks awesome, I'm surprised, but I'm disappointing of 2 things. First time when I start ubuntu it freeze. 1st thing:I don't know how to make a broadband connection,that's what I'm using in W7. In the top right of the corner it says "wired connection off ,you're offline" 2nd it doesn't recognize the E drive, the drive where it is installed.
I'm using a wired ethernet dongle due to my machine not having an ethernet port, however it sometimes drop connection, how can I diagnose whether if the dongle is faulty or my system is having trouble maintaining a connection.
I created a wireless ad hoc network using network manager. That was simple. I have friend who doesn't have a wireless card, and still would like to join the LAN. It would be nice if he could have a different IP address Is this possible?
I have got a laptop running Debian squeeze. I wish to share the wireless connection of the laptop (wlan0) to the ethernet port of the laptop, so that I can share the wireless connection to my desktop PC which is connected to the ethernet port.
I have read the article on Ubuntu community: [url]
I followed the steps, and the /etc/network/interfaces file on my laptop is:
Now the situation is: My laptop can connect to Internet (i.e. ping debian.org from laptop is fine), my desktop PC can connect to my laptop (i.e. ping 192.168.1.1 from desktop PC is fine). However, the desktop PC cannot reach the Internet.
I also read the information on Debian Wiki: [url]
It seems I must install and configure ebtables before sharing my wireless connection to ethernet port. Is it true? (But why the article on Ubuntu community doesn't mention it?) Or I just made some mistakes?
I run Ubuntu 10.04 on a PackardBell laptop, with an Orange Livebox 2 providing ADSL. I am connected to the Livebox via WiFi, but I can't connect using the ethernet cable. I think that in making changes to the system some time ago I must have ruined something, but I can't work out what.
I've got Puppy Linux on a USB key, and yesterday, while I was on the internet with it, it hanged. I didn't know what to do, and I rebooted from the button (I now know what to do ). The problem is that, after rebooting, Puppy doesn't recognise the router. I've tried to apply the drivers that are on Puppy, but there aren't any compatible.
My router is a Xavi 7968 and my Network Card is:
NIC Fast Ethernet PCI Familia RTL 8139 from Realtek
(On Realtek's website, there isn't any driver linux-compatible)
I have a Zotac Ionitx A-U. I can't get it to establish an internet connection with the wired ethernet within Ubuntu. The chip is detected, but trying to bring up the connection stalls out at trying to obtain a DHCP lease, like this:
DHCP DISCOVER ... DHCP DISCOVER ... No DHCPOFFERS received Specs: Ionitx A-U Ubuntu 10.04 x64 kernel 2.6.32-22 (also didn't work in 9.10)
I acquired an older hp compaq presario computer version 6310us, and initially installed mint, followed by Ubuntu 9.04. Neither one recognized the onboard ethernet port. I checked the bios, and LAN is enabled. It is also enabled in the drop down menu from the toolbar on the desktop. The cable works fine on other computers, and the light on the ethernet port flashes like it does when the cable is connected. I'm new to linux, so not sure what to do to get the connection working.
I have a generic P4 desktop computer with Debian Squeeze. Since instalation my wired ethernet connection will slowely slow down and then quit when surfing the web. Sometimes it seems worse than othertimes. If it fails I usualy can get it to come back back up by going to Network Connections and clicking on "wired connection"and them just closing the window. It will work for a bit but the conection will inevitably quit in a short time again. Interstingly it seems mostly a problem with web browsers as doing upgrades, package instalations, using SMXI and things of this sort do not seem to be a problem. I have tried both Epiphany and the Squeeze default Iceweasel with identical results. Also when using Google Earth a similar situation occurs in about 2 minuits of use. The same computer running Debian Lenny with Epiphany and WXP with the dreaded IE do not have this problem.
I recently did some troubleshooting on a USB wireless dongle hooked up to my Mint distro. I need the USB wireless to access a home DSL wireless modem out to the Internet. The wireless DSL is on 192.168.0.1
I also have a 10/100 ethernet NIC in the computer, for non-wireless connections. The wired ethernet is all 192.168.1.1. I noticed in /var/log/syslog that there are numerous "DHCPDISCOVER on eth0 to 255.255.255.255 port 67" messages.
Since eth0 has a hard-coded IP, I dunno why DHCP is trying deal with it. Can I turn off DHCP activity against eth0? How to do that?
After upgrading from karmic to lucid yesterday made my RTL 8111 -network card die. It's integrated on Intel D510mo mini-itx board.
dmesg:
Code:
After some googling I found out a lot of forumposts about the same problem from year 2007, but the troubles seem to disappear on the newer versions and seem to be back now? With those posts I managed to get the link up by using ethtool by setting autoneg off and setting speed to be 10mbps and half duplex. Any other speed/duplex combination fails.
One suggestion I found was to install r8168-driver from Realtek instead of the r8169. It didn't help, result was very much the same.
I booted to 9.10 live-cd and there the network worked as intended (100Mbps, I dont have a gigabit switch)
I really wouldn't like to fall back to 9.10, but my file server is not very usable with 10mbps.
A command like (single quotes used in the command):
Code: ssh -L '[::1]:3128:127.0.0.1:3128' ...
is getting an error message like:
channel_setup_fwd_listener: getaddrinfo(::1): Address family for hostname not supported
This is supposed to be an IP address, not a hostname, for the localhost in IPv6. Anyone know what is wrong with this? Addresses like this work OK in rsync. I know I can use ip6-localhost as a hostname. But right now I'm testing actual IP addresses in IPv6 to see what programs can or cannot handle it.
I can't figure this out for the life of me. I am new to Linux too. Wireless works fine. I plug my Ethernet in and turn off wireless and I cant surf the web, download, etc...Network Manager finds the wired network under eth0 and it works perfect on my non-linux desktop (nervous to even mention Vista around here). Firewall was set up with basic setup (I didn't make any changes). I have a Sony vaio VPCCW21FX with fedora 13. Can anyone point me in the right direction?
I have a Dell Studio 1501 Laptop and I want to bridge the wireless with the ethernet port so I can hook my xbox360 to my laptop.
I've spent the last 2 hours trying different techniques but nothing is working.
I'm running Ubuntu 9.10 so the last thing I tried was going into the network manager, clicking on wired, editing the ethernet port and allowing it to share. This did nothing.
I tried to share the connect with firestarter but that did not work either.
