Comment 9 for bug 677701

Okay went and tried other distros over the last week or so...

First I think your problem is specific to the intel NIC/chip on your machine(s). That being said, updating the specific intel driver may work fine in your situation, but I was addressing the larger more general issues regarding ethernet connections over the last few months using the .33 - .35 kernels. I have a nvidia MCP-67 chipset ethernet controller. It actually uses realtek chips. I also went and installed a seperate PCI ethernet card, an older Linksys. I get the same problem with either NIC and it is not right away nor is it all the time. It only happens AFTER I log into windows 7 then try and login to linux. At first I can reset my router and all is working again but this is a temporary fix.

As I said I have gone with Ubuntu 10.04 which worked fine until either the updated kernel or I installed WIndows 7(no idea which because Windows 7 install was just before the kernel update). Soon after I had an issue with my NIC not connecting. I went through every forum I could find and met with varied levels of success using all kinds of methods. I updated fiirmware, and it worked. After a couple days I had to restart my router to get DHCP to work. I tried updating to 10.10 again same thing. Tried using Puppy linux and the tools there to get a connection and no luck. I tried Kubuntu 10.10, same issues, Pinguy OS, Gentoo live dvd, Debian squeeze, Slackware, and with every single one I got the same problem. Now my router is working fine, and has had no issues for over a year of use. Windows XP and WIndows 7 works with it without a single problem. Yet somehow with these linux kernels the thing has DHCP issues.

The OS's (linux) all recognize my NIC's (both of them), both are recognized fully and show no problems at all. Yet somehow after running windows7 and then logging back into linux I cannot connect with either card. And the only thing that has worked for me reliably has been to restart my router and ensure my linux OS uses the same PC name as my Win7.

Now it must be something with either DHCP and the kernels, a windows 7 problem involving home networking and such, or some other issue i am unaware of. Updating firmware worked in 10.04 for a short time only but 10.10 which shows the firmware installed in synaptic, still has the same issues. This is the same in every distro I have tried using any combination of those kernels. I can make it work by swapping the Eth cable between the two NIC's and restarting the router but as long as I have to do that I don't think I will be using the Linux drive very much...
