One computer only on home net having DNS lookup trouble

I have one linux machine on my home network causing trouble with name lookup. It finds some names but simply won't find others. When booted with windows it works, but with ubuntu, the browser times out if asked to go to one of the bad names. It so happens google.com is bad. I tried using host to see what I could see. Here is what it says on one of the good machines:

$ host google.com
google.com has address 72.14.207.99
google.com has address 64.233.187.99
google.com has address 64.233.167.99
$

And here is what it says on the bad one:


$ host google.com
google.com has address 72.14.207.99
google.com has address 64.233.187.99
google.com has address 64.233.167.99
;; Warning: Message parser reports malformed message packet.
;; connection timed out; no servers could be reached
$

All network settings are identical on all machines, except of course for the machine's own ip address. (I am using static addressing.) But the misbehaving machine is a newly set-up laptop with Kubuntu, and I have to manually click on the wireless connection to make it connect, and i also find that when turned on, the cable port is showing as connected and I have to click on that to disconnect it (as there is no wired connection, only wireless).

Lastly, actually typing in the IP address shown by the host command brings google up instantly, so the network is connected.

Can't think of anything else to try, so TIA for any suggestions!
