Networking suddenly stopped working
 

I've been using Ubuntu quite happily on my Fujitsu Siemens Lifebook laptop for months now. Today though, all networking failed. Wireless and Ethernet connections no longer work. If I boot into windoze, everything works. My Ubuntu desktop still works too.

Can anyone explain this? Might there have been a software update that my laptop didn't like? I'm at a loss how to resolve this with no working connection.

Any help most gratefully received.

Thanks.

Open a konsole, and run the command '/sbin/ifconfig' ( without the quotes ) and post the results. This will show the status of all your connections.

It would also help if you posted the result of 'netatat -r' This shows the routing information.

Can you connect to your router? From a web browser, type the ip address of your router in the address bar and see if it connects. Post the results.

Well this is just too wierd! I've been fiddling about with this laptop for hours trying to get it to connect. I read your response so I booted back into Ubuntu and it connected wirelessly straight away!

I get the feeling this may be the start of something rather than the end.

Many thanks for the response :)

The commands I posted are the first places to look to determine status, so give them a try while things are working, and you will start to see the differences when things don't work.

dmesg is also your good friend.

Hi,

I would add that by using 'ifconfig -a' will show all devices even the ones that are down. :)

Thanks all :)

This is the output from /sbin/ifconfig with network working is as follows, does it look healthy?
