Troubleshooting Common Wireless Problems – Quick Fixes That Work
Introduction
Wireless networks are the backbone of modern businesses—supporting everything from cloud systems and VoIP phones to EPOS and mobile devices. But when Wi-Fi problems hit, productivity can grind to a halt. Whether it’s slow speeds, dropouts, or poor signal strength, the good news is that most issues are fixable with the right approach.
At TTS Ltd, we help businesses identify and resolve wireless problems efficiently, using professional tools like Ekahau Pro and Sidekick 2. Here’s a guide to the most common wireless issues—and how to fix them.
Slow Wi-Fi Speeds
Symptoms: Pages load slowly, video calls lag, file transfers crawl.
Possible Causes:
• Bandwidth congestion
• Interference from nearby networks or devices
• Outdated hardware
Fixes:
• Move high-traffic devices to 5GHz if supported
• Use a Wi-Fi analyser to check for overlapping channels
• Upgrade access points to Wi-Fi 6 for better throughput
.
Unstable or Dropping Connections
Symptoms: Devices disconnect randomly, calls drop, apps timeout.
Possible Causes:
• Signal interference
• Poor AP placement
• DHCP conflicts
Fixes:
• Perform a wireless site survey to detect weak signal zones
• Relocate or add APs to improve coverage
• Check and renew DHCP settings on your router or controller
Weak Signal in Certain Areas
Symptoms: Wi-Fi is strong in one room but dead in another.
Possible Causes:
• Building materials blocking signal
• Access points too far apart
Fixes:
• Install additional APs or mesh nodes in low-signal zones
• Reposition APs for more even coverage
• Use directional antennas or signal boosters as needed
Too Many Devices on the Network
Symptoms: Slow speeds, frequent disconnects, performance drop with more users.
Possible Causes:
• Overloaded access points
• Network not segmented properly
Fixes:
• Upgrade to business-grade wireless controllers
• Segment guest, IoT, and staff traffic onto separate VLANs
• Add more APs to balance load
Authentication or Connection Errors
Symptoms: Devices fail to connect or repeatedly ask for passwords.
Possible Causes:
• Incorrect security settings
• Expired or misconfigured RADIUS credentials
Fixes:
• Check SSID security settings (WPA2/WPA3)
• Reset saved network credentials on client devices
• Reconfigure or reset access point authentication settings
Interference from Non-Wi-Fi Devices
Symptoms: Intermittent dropouts near kitchen equipment, industrial devices, or cordless phones.
Possible Causes:
• Microwave ovens, Bluetooth, and wireless cameras operate on 2.4GHz
Fixes:
• Move devices to the 5GHz band
• Eliminate or shield sources of interference
• Replace older 2.4GHz-only equipment
