Upgrade to Buster (following the release notes and hints given in this group)
then to Bullseye. Any particular reason why you must use pae rather than
the standard 32 bit kernel?
Checking, it looks as if the N280 is 32 bit only.
It's a nice, small thin client drawing low power but don't expect
superb performance at this class of hardware.
All the very best, as ever,
