Ethernet card fails to detect after every 3-4th bootup

Postby mashkoor.qadir » Fri Oct 21, 2011 4:03 pm

Hi,
I am having a problem with my new Linux box, Previously I was working on Centos 3.6 version. But recently I got new Hardware p4 HT with 3Ghz 1gb ram, so i download centos 4.3 version and install that, Every thing works fine for 2-3 days...using On board ethernet card.

But now every after 3-4 days When I boot up my machine it doesn't detect Ethernet card, I mean my linux box report problem that ethernet card is having wrong mac address. and fail to start ethernet device.

When I reinstall ethernet drive and try to enable/disable onboard card in alternative reboots it start working again.. I thought might be Onboard card is not supported or is damage, so I got new Ethernet realtek Card, but same problem still exists.

It only fails to detect ethernet card every 3-4 days, Since its my experimental machine, I reboot machine 2-3 time a days but never had problem during this time..

Please suggest

May be you can change like this.

Code: Select all

ifconfig eth0 |grep HWaddr

eth0  Link encap:Ethernet HWaddr 00:40:28:BA:d1:40

# ifconfig eth0 down
# ifconfig eth0 hw ether 00:40:28:BA:d1:50
# ifconfig eth0 up
# ifconfig eth0 |grep HWaddr
