Did all per Dell instructions above being careful to use drivers from Dell TB15 page as some on XPS 13 driver page slightly older
Also in Device Manager had to find ASMedia… USB Controller, was showng Microsoft driver in use despite above Dell/ASMedia driver install.  Dd update driver with search option and it found correct driver. Wired Network now stable.
