Why is my WiFi slow at night?

Quick answer

Usually the culprit is your router or too many devices competing for bandwidth, not your internet provider — try a restart and checking connected devices first.

If your connection drags in the evenings but is fine in the morning, the problem is almost never your provider — it’s your router or the number of devices eating up bandwidth.

The 3 most common causes

First, the router — if it hasn’t been restarted in months or is an older model, its performance degrades gradually. Second, network congestion during peak hours (common in apartment buildings). Third, devices running in the background — smart TVs, cameras, downloads running silently.

  • Restart your router once a week
  • Check how many devices are connected
  • Try the 5GHz network instead of 2.4GHz if you’re close to the router

When you need a technician

If you’ve tried the above and the problem persists, you likely need an equipment upgrade or better router placement in your home/office — something a technician can diagnose in minutes.

80% of the “slow WiFi” calls we get are solved with proper router placement, not new equipment.
