Wired network issue with HP dv6 laptop

I have been having thisproblem for some time now and was wondering if someone  can help me. I have a wired connection that disconnects from the the network sporadically. every few months  or so. I know the cable is fine because I tried it in another laptop and it works fine.

All other computers on my LAN work fine.

Here is what I have done so far:

I also tried this:

sudo service network-manager restart

Nothing seems to work.

Re: Wired network issue with HP dv6 laptop

I just rebooted with my Puppy Linux CD and I have a wired network connection. So far booting in Crunchbang or Linux Lite fails to connect to my wired network.  Is this a driver issue?

Re: Wired network issue with HP dv6 laptop

Works fine now after booting into my Puppy Linux CD and trying different tools to get the network going. Any ideas on what may have caused this? Are there tools I can use that will attempt to "jumpstart" the network?

Glad it works again smile

Find which interfaces are available with

ifconfig -a

Bring up your ethernet (assuming it is shown as eth0) with

sudo ifup eth0

There are several other network commands obviously, so search out "linux manual network configuration", for possibilities.

Re: Wired network issue with HP dv6 laptop

Thanks Damo. Not sure what causes this. It only happens with the dv6.
