Ethernet detection issue

Postby BigBenCG » Sat Apr 03, 2010 9:20 am

I am endeavoring to become better at hardware troubleshooting in Linux and need some assistance.

For the record, I am using Mint 8 Helena, I am not using mint4win, I have not manually installed any drivers nor am I using any third party repositories. All updates and applications have been installed via MintUpdate.

I am using an HP Laptop, DV6768SE, and for the last couple weeks the name of the MAC address for the on-board Ethernet adapter changes after every restart. The controller is working well and I am not experiencing any issues while using the on-board Ethernet controller. I was made aware of this behavior by noticing that the name of the wired Ethernet controller was incrementing up on digit after every restart. At the time of this message I am up to eth35, as far as I can tell the number (00:06.0), whatever that means, is constant.

I am currently using the internal Atheros AR5001 Wireless Adapter which is not experiencing the same issue of changing MAC Addresses. I mention the wireless to aid in any advice and to explain why the code below is not showing any packet statistics.

I believe the issue started around March 22nd, reviewing my update history there were 14 updates installed on that date.
thunderbird Ver.
samba-common-bin Ver. 2:3.4.0-3ubuntu5.5
smbclient Ver. 2:3.4.0-3ubuntu5.5
samba Ver. 2:3.4.0-3ubuntu5.5
samba-common Ver. 2:3.4.0-3ubuntu5.5
libsmbclient Ver. 2:3.4.0-3ubuntu5.5
mozilla-thunderbird Ver.
libwbclient0 (2:3.4.0-3ubuntu5.5), and 6 kernel updates:
linux-image-generic Ver. 2.6.31-20.33
linux-generic Ver. 2.6.31-20.33

This is an old problem with nvidia NICS though I'm not sure why it has re-appeared for you. It was probably the kernel update, maybe there's a regression in that version? There is a new kernel update to 2.6.31-21 which you might want to try, otherwise there is an explanation and solution in this thread -
[Edit] your original post and add [SOLVED] once your question is resolved.
