Why is my internet slow only in the evening?

Evening internet slowdowns usually happen because demand spikes at the same time: people in your home and nearby homes are streaming, gaming, video calling, and downloading after work or school. The most common causes are network congestion from your ISP, overloaded home Wi‑Fi, or a device/app using bandwidth in the background.

Quick way to narrow it down:

1. Run a speed test in the morning/afternoon and again during the evening slowdown.
2. During the evening, test both Wi‑Fi and a device plugged directly into the router with Ethernet if possible.
3. If Ethernet is also slow, the issue is likely your ISP connection or neighborhood congestion.
4. If Ethernet is fine but Wi‑Fi is slow, the issue is likely your router, Wi‑Fi interference, distance, or too many devices.
5. Check whether TVs, game consoles, cloud backups, security cameras, or phones are downloading/uploading at night.

What you can try:

• Restart your modem/router, then update router firmware.
• Move your router to a central, open location away from walls, TVs, microwaves, and metal objects.
• Use 5 GHz or 6 GHz Wi‑Fi for nearby devices; use 2.4 GHz for longer range.
• Wire high-demand devices like gaming consoles, TVs, and work PCs with Ethernet.
• Pause scheduled backups, game updates, and large downloads until overnight.
• Enable QoS/traffic priority on your router if available.
• If evening Ethernet speeds are consistently far below your plan, contact your ISP with speed-test times and results.

If your ISP uses a shared local network, evening slowdowns can happen even when your equipment is fine. In that case, your best options are getting the ISP to fix capacity issues, switching providers, or moving to a less congested technology if available.
