Problem Description

Your Reolink camera goes offline every evening or night and comes back in the morning. The pattern repeats daily. WiFi cameras are most affected. The camera works fine during the day but disconnects around the same time each night. This is usually caused by WiFi congestion during peak evening hours or the camera switching to night vision mode which draws more power and causes WiFi instability.

Symptoms

  • Camera goes offline every evening around same time
  • Morning recordings missing from overnight hours
  • Camera reconnects by morning automatically
  • Live view fails at night but works during day
  • Motion alerts stop coming at night
  • WiFi cameras affected but PoE cameras fine

Recognize these? Here's what usually causes it.

Common Causes

  • Evening WiFi congestion from streaming and gaming
  • Night vision IR LEDs increasing power draw on battery
  • Router auto-channel switching during low usage hours
  • ISP bandwidth throttling at peak hours
  • Camera power supply insufficient for night mode
  • 2.4GHz interference from neighbor networks at night

Most fixes happen in the first 3 steps.

Warning

Do not place WiFi extenders in the garage or outdoors where temperatures fluctuate. Extreme heat and cold degrade WiFi extender performance and lifespan.

Step-by-Step Solution

1

Check WiFi Congestion

Use a WiFi analyzer app on your phone to scan 2.4GHz channels at the time the camera drops. Evening hours bring heavy WiFi usage from neighbors. If your channel is congested switch to the least used channel in router settings. Channels 1 6 and 11 are the only non-overlapping 2.4GHz channels.

2

Set Fixed Channel

If your router is set to auto-channel it may switch channels at night when traffic patterns change. The camera loses connection during the switch. Set 2.4GHz to a fixed channel and 5GHz to a fixed channel. This prevents the camera from disconnecting during channel changes.

3

Check Power Supply

Battery cameras draw more power at night with IR LEDs on. If battery is below 20 percent the camera may shut down WiFi to conserve power. Charge fully or add a Reolink solar panel. For wired cameras check that the power adapter outputs the correct voltage for your model.

4

Move Camera or Add Extender

WiFi signal may be marginal and tips over the edge during evening congestion. Move the camera closer to the router or add a WiFi extender midway. In the Reolink app check WiFi signal strength under device settings. Below 50 percent signal is unreliable.

5

Switch to Wired

If your Reolink model supports PoE running an ethernet cable eliminates WiFi issues entirely. PoE provides both power and data over one cable. This is the most reliable solution for cameras that go offline due to WiFi problems. Reolink NVR systems with PoE are rock solid.

Quick Solutions

Add dedicated WiFi access point for cameras
Set fixed WiFi channel to avoid auto-switching
Switch to PoE connection if possible
Upgrade power supply or use solar panel
Move camera closer to WiFi source
Schedule router reboot after midnight

Still having issues? This is usually the deeper cause below.

This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.

Pro Tip

If switching to PoE is not possible consider a powerline ethernet adapter. Plug one into an outlet near your router and one near the camera. Run a short ethernet cable from the adapter to the camera. This provides a wired connection without running cables through walls.

Real-World Insight

Most WiFi drop-offs happen right after a router reboot or ISP swap — the device reconnects to the network but silently loses its cloud registration.

What Usually Goes Wrong
  • Evening WiFi congestion from streaming and gaming
  • Night vision IR LEDs increasing power draw on battery
  • Router auto-channel switching during low usage hours
  • ISP bandwidth throttling at peak hours
  • Camera power supply insufficient for night mode
