How to Fix Office WiFi Dead Zones in Dubai: Step-by-Step Troubleshooting

Step 1: Validate It Is Coverage, Not Bandwidth

Run tests from three locations: near AP, hallway, and dead-zone desk. If speed is good near AP but poor in one zone, this is coverage design, not ISP speed.

Step 2: Check AP Placement

• APs should be ceiling-mounted and central to user clusters
• Avoid placing APs above metal cabinets or near elevator shafts
• Keep APs away from thick concrete pillars where possible

Step 3: Clean Channel Plan

+Set channel width appropriately (40 MHz or 80 MHz based on environment density).

Step 4: Tune Transmit Power

Too-high power creates sticky clients and poor roaming. Set medium power for most office APs and retest.

Step 5: Validate Roaming

Walk-test during a Teams/Zoom call between zones. If calls drop during movement, tune minimum RSSI and fast-roaming settings.

Step 6: Add AP Only After Tuning

Do not add APs before fixing channels and power. Extra APs with bad planning increase interference.

Quick Escalation Rule

If more than 15% of desks show RSSI below -67 dBm, run a professional site survey and redesign.
