Slow or Intermittent Business Wi-Fi: What to Measure First

How to identify the cause of slow business Wi-Fi?

The wired and Wi-Fi experience should be compared, in different places, times and devices. If the wired link also fails, the problem may be with the Internet, the router, or the network. If only Wi-Fi fails, it is worth checking coverage, interference, channels, capacity, drivers and location of access points.

Risks to review

• Restart or restore computers without saving their settings.
• Add repeaters without measuring interference and capacity.
• Share the same network and password between staff, guests and critical devices.
• Confusing a good signal with sufficient capacity or stable internet connection.

Safe recommendations

1. Register place, time, device, signal strength and affected service.
2. Compare a wired test with a Wi-Fi test using the same link.
3. Determine if a device, access point, zone, or entire site fails.
4. Review drivers, firmware, channels, channel width, and 2.4, 5, or 6 GHz usage.
5. Separate guests and untrusted devices from internal services.
6. Back up your configuration before rebooting, upgrading, or replacing network equipment.

When to seek specialized help

• The failure affects calls, billing, video conferencing or critical systems.
• There is no administrative access or configuration backup.
• More access points, segmentation or a coverage study are needed.
