NICs fail on 7.10-8.04 upgrade

I did the upgrade to 8.04(.1?) 2 days ago & upon the restart, neither NIC was operating. They had been working with 7.10 otherwise I wouldn't have been able to do the on-line upgrade (& yes, they work upon booting into Windoze).

One NIC is an Intel Pro/100 VE onboard NIC; the other is a Sohoware 10/100 PCI NIC.

The Intel was my original NIC when I installed 6.06 LTS from CD. Intel NIC worked. Then I upgraded on-line to 7.10 when it was offered. Intel NIC worked. At some point, I added the Sohoware NIC. At that point, I started having problems with the NICs not working, but I was able to get them working. The NICs were working when I did the on-line upgrade to 8.04(.1?), but now they're not.

Any ideas?

Are they still appearing to the system via lspci? Are the driver modules for them loaded (lsmod | grep module_name)? This sounds like quite a mysterious problem. Also, have you searched the Ubuntu launchpad site for other people reporting this problem?

Well, there appears to be some sort of issue with 8.04 and NICs. I have two computers that have the same NIC, only one runs 32 bit and the other 64 bit. For some reason, the 64 bit came out alright but the 32 bit does not seem to be capable of handling the NIC. I ended up compiling the driver from source... I did a fresh install instead of an upgrade, by the way.

Still, having two devices fail is quite odd. I would not be surprised if it was related to adding the second NIC and configuring it manually. It is quite possible that the upgrade uses defaults that clash with your manual edits. I guess I know what I am talking about, I had a bit of a problem myself adding a second NIC that just would not work. It turned out that my network settings were at odds with the udev rules in /etc/udev. Have you looked at the output of dmesg? It gave me my first clue about what was wrong.

Sorry it took so long to reply. I was weighing my options & just not in a hurry to do anything.

I decided to bite the bullet & do a clean install since Ubuntu is installed on a separate disk from my Windoze. I thought I would just be able to pop in the CD & click install, but even that didn't work. The 8.04 install failed. Since I didn't have anything on the Ubuntu disk I needed, I deleted all the partitions & started over. This time the install went smoothly.

When all was said & done, both NICs were installed & working. I have other issues, but they will have to be another thread, another time.
