Wireless Network Troubleshooting & Diagnostics
Diagnose and fix wireless network issues with systematic root-cause analysis
What You Can Do
You can perform comprehensive wireless network diagnostics to identify connectivity failures, performance bottlenecks, and security vulnerabilities. The skill guides you through systematic troubleshooting workflows that pinpoint root causes and provide actionable remediation steps, whether you're dealing with dropped connections, slow speeds, or unauthorized access attempts.
Features
evaluate broadcast power, dead zones, and optimal router placement
identify overlapping networks and recommend optimal channel selection for 2.4GHz and 5GHz bands
scan for weak encryption, default credentials, WPS vulnerabilities, and unauthorized devices
analyze connection logs to detect intermittent drops, driver issues, and device-specific problems
distinguish between local device issues, network congestion, ISP limits, and hardware constraints
resolve authentication failures, driver conflicts, and protocol mismatches
prioritize traffic, configure QoS settings, and identify bandwidth-hogging applications
assess WiFi security standards (WEP, WPA2, WPA3) and recommend migration strategies
Example Output
Signal Quality Report:
- 5GHz coverage: 92% with -45 dBm at desk (strong)
- 2.4GHz coverage: 98% with -35 dBm (strong but congested)
- Recommendation: Migrate to 5GHz band, reduce 2.4GHz transmit power
Security Assessment:
- Current: WPA2 with AES encryption ✓
- Risk: 4 unknown devices detected ✗
- Actions: Enable MAC filtering, disable WPS, rotate pre-shared key
Root Cause Analysis:
- Symptoms: Drops every 2-3 hours on laptop
- Diagnosis: WiFi adapter power-saving feature
- Resolution: Disable power management in device settings
- Expected outcome: Stable connection
