Not that I know of. I was offline for two or three hours when I switched to
the new router. It would be an extreme coincidence if they had changed the
MTU exactly during that time.

With 3.0 it probably produced quite a number of fragments, but everything
worked. And it stopped just when I went online with the new router.
