Why is Wi‑Fi slower in the evening?

More household traffic and neighbouring channel use can raise contention; an ISP network issue is also possible. Compare gateway and client tests at matched times.

What to check

Channel busyness; total usage; latency; gateway speed history.

When to get help from a person

Escalate recurrent gateway degradation at peak time.
