wired connection fails on startup 12.04

Asked by John B

Hi. I have a brand new Asus X53E laptop running only Ubuntu 12.04 and have a problem with establishing a wired internet connection at startup. I usually have to reboot several times before a connection is established. Once it is establshed, there is no problem and the connection lasts. If I manually disconnect a working connection, the same problem exists.

The wired connection on my desktop, running a previous version of Ubuntu works fine. I am trying to figure out if the problem is with the laptop hardware or with the software. Any suggestions?

The system log errors for one cycle of disconnect and connect are:

Can you give the output of:

sudo lshw -C network; lsb_release -a; uname -a; sudo rfkill list

Thanks

Also do you dual boot the system?

Thanks

Sure. It is not a dual boot. Only Ubuntu.

Could install wicd and uninstall network manager and reboot

HTH

John B (j200477) said : 		#4

Thanks actionparsnip. I tried your suggestion, installed WICD, uninstalled network manager, and reboot. Same problem. So I reinstalled gnome network manager and uninstalled WICD. Again, same problem.

However, I did find that by bypassing the router, the wired network will establish communication via gnome network manager on my laptop. The problem is not entirely in the router, however, because my desktop, running an older version of Ubuntu, can establish a wired connection via the router.

I also found that although the laptop connection cannot be easily established with the router in place, a wireless connection can be easily established. So for some reason, the problem is only with the wired connection when using the router.

Lastly, just to make sure the problem is not in the LAN cable, I unplugged the working cable from my desktop and tried it with my laptop, and same problem. So it is not the cable.

Any more suggestions?

Are you intending to use wired connection and always use DHCP?

Revision history for this message
John B (j200477) said : 		#6

Yes, I would like the option of using a wired connection. I would use it if it worked. And I assume I would need to use DHCP, as that seems to be the default for my network.

actionparsnip (andrew-woodhead666) said : 		#7

But is that all the system will ever use?

Revision history for this message
John B (j200477) said : 		#8

I don't understand the question. I would like to be able to use either wired or wireless connections. There may be times when either could come in handy. I don't know about the DHCP part. I assume that my Internet provider uses DHCP.

Revision history for this message
actionparsnip (andrew-woodhead666) said : 		#9

will the system only use the wired connection in it's life and nothing else?

Revision history for this message
John B (j200477) said : 		#10

No. As I said, I would like the ability to use both the wired and wireless at different times.

All I can suggest is report a bug. If you were only using wired you can remove all gui apps and use interfaces file to use DHCP on the interface. Makes the SO sleeker

OK, thanks actionparsnip. From the information I provided, can we rule out that it is a hardware problem specific to my laptop?

Thanks actionparsnip, that solved my question.
