Path.resolve() doesn't raise on a nonexistent path — it just returns the
syntactic path unchanged — so when driver_name() ran before the radio's
netdev had enumerated (startup race with USB re-enum), it silently
returned the literal string "driver" instead of None. The loop's retry
guard (`if driver is None: retry`) never fired since "driver" is truthy,
so the bogus value was cached for the service's entire uptime and the
queue-flush wedge regex could never match real driver names — the 3rd
check added 2026-08-19 was silently inert. Fixes 2026-08-23 recurrence
where the 5GHz SSID went invisible and hostapd never got restarted.
