All networking gone following update (SOLVED)

[cjs1949]

Having just done the normal update, the first on this laptop (Samsung P28) for about two months, all network connectivity has gone both ethernet and wireless. It finds the adaptors, knows what they are but refuses to connect. Anyone else experienced this?

A few of questions which you've probably already done.

What desktop are you using?

Have you rebooted?

Any error messages appearing?

Tested connection in another account? 

Remove existing network connection - reboot - and create a new one?

Well, not lately, but from time to time.

What steps have you taken? If by "It" you mean PCC and all hardware is recognized there, then have you tried opening konsole and checking what ifconfig says, as well as whether or not ifup will make the connection? Are you sure your security settings, passwords, etc, are all correct?

Thanks or your fast response but yes tried all that but as I could do nothing else, online anyway, I did a reload of 2011.6 followed by an immediate update and so far it's ok again. Just shows that rolling releases have to be reloaded occasionally

Perhaps a simple restart of the networking service would of been enough.  On my laptop, Acer 3100, the kernel did not recognize my wireless at all. I had to load the latest kernel 2.6.38.8-pclos3.bfs before it would work again.

I would disagree with your conclusion ......  it may have been easier for you to do this ....  but that does not mean it was necessary

I had a similar problem a long time ago following a kernel update. Sometimes you have to delete the files in /etc/sysconfig/network-scripts/wireless.d/ and rebuild them if a new kernel uses different rules for the same wireless card.

I did numerous reboots to no avail but the network scripts bit sounds highly likely although afaik I didn't update the kernel - perhaps that was the problem, needed a new kernel and the reload did it. It only took 15 mins anyway and I had no docs to worry about. The one oddity though was that the localisation script was asking for a later file than was in the repos so I had to localise it manually for UK. I shall note that for next time.
