Ubuntu Networking :: Disconnect The Network On Shutdown?

Nov 22, 2010

A month ago I had (and still have) a weird problem were leaving my switched off computer plugged into the network killed the whole network.

[URL]

well I have found a fix, if I disconnect my computer via software (Right click and disconnect "eth1" and shut down the network will remain up. I want to make a script that runs on shutdown that simply disconnects "eth1". Are there any pre-made shutdown scripts in ubuntu that I can simply add "eth1 enabled = 0" or something.

Ubuntu Networking :: Wireless Network Connection Disconnect-reconnects Every 5 Min

Jul 31, 2010

I recently installed Ubuntu 10.04 on my Acer TravelMate 3270 notebook (with Windows 7 dual boot) for everyday use. All is great except i started to notice my Wireless Network get disconnected and then reconnects every 5 minutes or so. Also the NetworkManager Applet 0.8 keep annoying me with the notifications that its disconnected and then reconnected.

I do not have this issue while using Windows 7 (in the same area). Can this be fixed. As i really want to move my day to day computing need to Ubuntu.

Debian Hardware :: Realtek RTL8101E Wired Ethernet Random Disconnection

Aug 23, 2014

I have this wired problem with my realtek rtl8101e ethernet. It keeps on disconnecting randomly with my router. My computer is connected to D-link router via LAN cable. This problem does not occur in my windows xp os.

Networking :: Random Network Connection Loss On Debian Server?

May 15, 2011

I have been having this problem for about two weeks now where Debian's network and internet connection randomly fails. It works perfectly fine and hosts all the services I need for a while, and then without warning all network connectivity fails. I can't ping any other network device. Regardless of how much I try to fix it, the only thing that works is restarting the computer. First, the server went 7 days without a problem; then 5 days; now it lasted 2 days. Judging from my Teamspeak server logs, it crashed today at 12:31. I grep'd through my log files and found this information:

Fedora Networking :: F14 - Can't Find Network (wired Or Wl)?

Feb 28, 2011

Issue: Using Fedora-14-x86_64-Live-Desktop.iso, I created a live usb and tried it on Dell M6400. I can boot into F14, see the internal hard-drive and other usb drives -- but F14 will not go on the network -- neither wired or wl networks.

I am not sure what additional information I need to provide to help resolve this issue. Perhaps some background info would help?: I am trying to move from XP to linux on the M6400. The latest Ubuntu live CD would not boot, the latest CentOS live CD could not find the internal drive; I got best results with the latest Fedora (and I am more comfortable with the F14 gnome interface than the F14 KDE, the Ubuntu, and the CentOS interfaces). I do not know how to investigate the inability of F14 to detect the ethernet cabled network. I was unsuccessful in my attempts to get the wireless to work: "lspci -nn" shows BCM4322 802.11a/b/g/n 14e4:4326 (rev01). I read [URL]../docs/linux_sta/README.txt and used what I learned in my attempts. Installing broadcom-wl-5.60.48.36-1.fc13.noarch.rpm, kmod-wl-2.6.35.6-48.fc14.x86_64-5.60.48.36-2.fc14.2.x86_64.rpm, and kmod-wl-5.60.48.36-2.fc14.2.x86_64.rpm (found at rpmfusion) did not help. I tried to build and install the sources from http://www.broadcom.com/support/802.11/linux_sta.php; the machines I had for building were 2.6.28-18-generic Ubuntu, fc5, and rhel5 -- attempts with these builds failed too.

Ubuntu Networking :: Wired Network - You Are Now Disconnected

Jun 12, 2011

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.

Networking :: Configuring Wired Network Ubuntu 10.04?

Feb 16, 2011

"Need help with entries for connecting to broadband. Was OK with ubuntu 8.04 which had boxes for DNS server, etc. The 10.04 asks for MAC address (?) and there is a space for "DHCP client ID". I don't understand these terms. I will appreciate some step-by-step instruction or example of how I may proceed, especially exact syntax for any command line work. I am in Chennai/Madras, and have a BSNL wired broadband connection to my Dell laptop." I have repeated what I tried in the ubuntu forum without success. 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=

Ubuntu Networking :: Wired Network Breaks When Idle

Feb 27, 2010

I'm having a problem where the wired network wired network (eth0) disconnects when the connection is idle for a while (usually tens of minutes). It works fine every time I boot up, but eventually it dies, and I can't ping the machine, or ping anything from the machine. ifconfig shows that it still has an IP address. Running ifdown/ifup causes it to work again. I intend for this machine to be a server, so I can't afford to go restart it when I need network access. sudo lshw -class network gives me this:

Ubuntu Networking :: Wireless To Wired Network Bridge

May 3, 2010

I am running ubuntu 9.10 on a dell xps m1530 laptop dual booting with windows 7. I am trying to achieve the following setup.

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

---- wired
==== wireless

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.

Ubuntu Networking :: Wired Network Not Working After Upgrade To 10.04

Jun 22, 2010

I recently upgraded to 10.04 and now my wired network no longer works. I am unsure if it worked at all since the upgrade as that computer is rarely used, but it was definitely working prior to the upgrade. It is some sort of Realtec card, I believe. Does anyone have any suggestions? I'm running 32 bit 10.04 on a 2 GHz P4.

Ubuntu Networking :: 10.04 Installed - Wired Network Disconnected

Jul 25, 2010

I installed xubunto 10.4 on my pc the other day and every thing was working fine and then the next day my wired network card went down. So I restarted it and it say Wired Network Disconnected. I tried doing sudo ifconfig eht0 up to try and bring the card back online but nothing happens. I also tried reinstalling xubuntu on my computer. Again my internet works then starts freezing up so I restart it and my ethernet card goes down again. I have tried also plugging it into the second ether net port on my computer but that does not seem to work. Also I went into my dhclient-script and went to the bottom to look at my network card stuff.

It reads
#Changed from 'ifconfig $interface inet 0 down' - see Debian bug #144666 ifconfig $interface inet 0
exit_with_hooks 2 "$@"

Ubuntu Networking :: Wired Network Not Working Properly?

Sep 12, 2010

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

Ubuntu Networking :: Wired Network Sometimes Doesn't Work

Feb 14, 2011

what is the command to restart the network services? ive forgotten i think it uses -hup switch though. about 1 in 20 boots on my desktop ubuntu system results in the system insisting its no longer on a network yet has a fully functioning network card. a reboot always fixes the issue but that doesnt seem like a long term solution to me. If I ping a neighbouring system I get nothing. (sent packet count increases in ifconfig) If I ping from a neighbouring system back to my desktop I get nothing (no change in packet count) I can bring down and back up the network interface with no results. A sniffer shows the system definitely isnt sending anything out Everything worked previous boot and will work again after a reboot.
