Root-cause wireless investigation
Wi-Fi Troubleshooting
A structured troubleshooting engagement isolates the root cause of wireless performance, connectivity, and reliability issues using RF measurements, controller telemetry, client behavior, and packet analysis.
What it is
Wireless issues rarely have a single cause. Coverage gaps, client behavior, channel design, interference, and controller configuration all influence how the network performs in production.
A troubleshooting engagement collects the data required to isolate the actual root cause, rather than treating symptoms. On-site RF measurements, spectrum analysis, controller data, and packet captures are correlated as needed.
The output is a clear explanation of the issue, the underlying root cause, and prioritized remediation recommendations aligned to the customer's environment and platform.
How it works
- Step 01
Scope the Issue
Document reported symptoms, affected clients, locations, timing, and business impact.
- Step 02
Collect Evidence
Perform on-site RF measurements, spectrum analysis, controller reviews, and packet captures as required.
- Step 03
Analyze and Correlate
Correlate RF, client, controller, and packet data to isolate root cause.
- Step 04
Deliver Recommendations
Provide a findings report with prioritized remediation and configuration recommendations.
What we investigate
Coverage Issues
Weak signal, coverage gaps, and cell-edge behavior that impact reliability and throughput.
Roaming Problems
Sticky clients, delayed roaming, and roaming decisions that affect voice and mobility.
Client Disconnects
Association failures, authentication timeouts, and unexpected client disconnects.
High Retry Rates
Excessive retransmissions that reduce throughput and increase airtime consumption.
RF Interference
Wi-Fi contention, non-Wi-Fi interference, and channel design issues identified through spectrum analysis.
Controller Configuration
SSID, RF, security, and RRM configuration issues that impact client experience.
Common troubleshooting scenarios
- Reported connectivity and disconnect issues
- Voice, video, or real-time application degradation
- Post-deployment performance concerns
- Persistent roaming or mobility problems
- Suspected RF interference
- Configuration or platform-related issues
