Unhappy Intermittent loss of eth0


I have an odd network problem. An inconsistent loss of eth0 altogether. I have googled and searched several linux forums but I can't find anything that helps. The problem started about two weeks ago.

I am using DHCP on a Billion 7300G with wireless disabled. All network connections are hard wired with Cat 6 patch cables.

The machine is dual-booting Vista and PClinuxOS and the network connection has no problems in Vista. I would have blamed hardware except that it works fine in Vista. Live CDs (Knoppix, PCL, Mandriva, DSL) also work intermittently.

Could it relate to a recent update of some kind? Xandros and PClinuxOS have the same problem, an earlier opensuse installation didn't have the problem. I removed Xandros and reinstalled PCL. I could be paranoid and assume that Vista is all-conquering and running interference, but I don't think that's the answer.

I simply don't know where else to look. I've been using Linux on and off for years and routinely for the last two years, but I'm a user not a guru. The network is simple. There is no workgroup or sharing set up. It isn't necessary for my usage. There are 4 computers - 1 XPSP2 (husband), 1 Mepis 6.5.02, 1 OSX 4.9 and this one, PCL 2007. When the connection fails, the light on the router is out. If I select Vista the connection is available.

None of the other computers have network problems and the laptop only loses the network when running Linux and it's immediate. It is either or not there. I have tested every port on the router and swapped every patch cable. It happens regardless of the port being used. I have rebooted the router several times.

I use Windows very rarely other than at work but I don't want to blow it away completely. I can't anyway until I can solve this network issue.

It only affects Linux and any advice would be appreciated.

hello

this may be due to driver compatibility issue.
if you are not loded correct type of driver your link for eth0 will not give up status.

please confirm once .if it correct driver means uninstall it and reload driver,it resloves your problem.

As far as I know I haven't changed the drivers. I had a network connection yesterday using PCL, but I don't have one today on PCL or a live CD. I do on Vista ??

Problem solved. Vista is not releasing the ethernet on warm restarts so linux can't use it. On a cold start from full shutdown, the problem doesn't seem to occur.

Until the Vista driver is able to release the port I'll use full shutdown and cold startups to get around the problem. I wasn't being paranoid it is related to Vista

I hope this helps someone else.
