   What, exactly, goes wrong on those devices?  There's more than one
way to "l[o]se internet".  As usual, showing actual actions with their
actual results (error messages, LED indicators, ...) can be more helpful
than vague descriptions or interpretations.

   When you "reun a tracert" of what?  Actual command?

   Or something else.

   Copy+paste of an "ipconfig /all" report on the laptop might be
interesting.  If it were configured with a bad IP address, then that

might cause some problems.
