Ubuntu laptop internet issues

[heiowge]

I've got an old laptop that I've put Ubuntu 12.04 LXF Remix onto (then upgraded to 12.10).

Problem is I have network access via wired and wireless, but no internet.

ping -c 3 followed by the IP for google gives me the expected results. However, if I follow it with www.google.com or www.google.co.uk, I get

ping: unknown host www.google.co.uk

Any ideas?

Obviously not getting any nameservers by DHCP. Check /etc/resolv.conf if there's nothing in there then that's likely to be your problem.
The network applet (on which ever desktop you have chosen) should enable you to get nameservers via DHCP or set them manually.

This happens to me when I start the laptop without it being plugged in to a power supply. If I disable networking, then turn it back on, it again connects to my router, but also the internet works. It never does this when plugged in though; it only happens when first booted from battery.

Not a solution, but at least you are not alone. I haven't checked the Ubuntu forums...

As Rhakios says DNS issue.

If using Network Manager, have a look at the connection info and see if it lists your IPS Primary / secondary DNS server IPs.

Compare that to your Desktop.

If /etc/resolv.conf is blank on the lappy or doesn't match the desktop, you could copy the file from the desktop to the lappy.
