I don't know whether this is a valid question or not, but is the user
you are logged on as an administrator?

Alternatively, which version of Ubuntu are you using and is it all up
to date?  Run Update Manager and click Check to see.  I ask this as
there is at least one bug in Launchpad which sounds similar to your
issue, but this was fixed some time ago.

Do you see the same issue on the wired connection?

On a side note I doubt very much if you will see any noticeable
improvement using alternative DNS servers.
