My own experience is that ifup/down works fine with ethernet
but is hopeless with wifi because there's nothing to restart
it if/when the signal drops out.

So I install wicd-curses which has a daemon to monitor the service
and restart it as necessary. You don't have to be root to run it
either.

However, you would need to remove/comment out the   iface wlo1
stanza from /e/n/i because its presence would prevent wicd from
managing that interface.

Remember to start with P in wicd-curses to check that it knows
to look for wlo1 and not wlan0.

(Please correct any misconceptions I might have.)

Cheers,
David.
