wired eth0 keeps on disconnecting

[Mike Kovacevich]

Initially installed 8.10 on my HP e-PC and upgraded to 9.04. Found that the inbuilt 3Com ethernet card was not working. Network Manager seemed to try to connect to my router for an IP addr but is unable to get an assignment. Tried then to set a static addr but this still didn't resolve the issue - the system merely sent a notification that the wired eth0 was connected and then seconds later reported that the interface was disconnected, and so on and so on...

Thought this issue may have been due to the upgrade so downloaded an ISO about 2 hours ago, burned it to CD and tried a fresh install. Same problem.

[Kurt Wall (kwall)]

Thanks for taking the time to report this bug and for helping to improve Ubuntu. Is IPv6 enabled? If so, does the problem persist if you diable IPv6?

[Mike Kovacevich (mikek)]

Kurt, looks like to old way of editing the modprobe.d aliases file is no longer an option??? What is the recommended way to disable ipv6 in Jaunty?

[Kurt Wall (kwall)]

From the command-line, I use "sudo sysctl net.ipv6.conf.all.disable_ipv6=1". Add "net.ipv6.conf.all.disable_ipv6=1" to /etc/sysctl.conf to make it permanent.

[Mike Kovacevich (mikek)]

Right, added the line to /etc/sysctl.conf and restarted. Still no joy getting the eth0 link up. Syslog reports:

[Mike Kovacevich (mikek)]

Anyone have any more feedback on this?

[Alexander Sack (asac)]

please attach complete syslog after reproducing. also output of lshal. Thanks. Also, please use static IP configuration again (so that dhcp is not run) and reproduce a few times. attach syslog parts capturing these steps too. Thanks.

[Pedro Villavicencio (pedro)]

We are closing this bug report because it lacks the information we need to investigate the problem, as described in the previous comments. Please reopen it if you can give us the missing information, and don't hesitate to submit bug reports in the future. To reopen the bug report you can click on the current status, under the Status column, and change the Status back to New. Thanks again!.

[kira (kyrandesa)]

I attached the syslog and lshal. However, I can't really try with a static IP.

[kingtiger01 (mnovick1988)]

Same thing is occuring on 9.10 and 10.04. r8169

Timing 3minutes~or less apart, IPv6 set to ignore in Network-manager.

Statically assigned IPv4

[Thomas Hood (jdthood)]

@Mike, is this fixed in Precise?

[Mike Kovacevich (mikek)]

Doesn't seem to be a problem anymore. Thanks.
