Wireless Network Troubleshooting & Diagnostics Assistant
Diagnose and fix wireless network issues systematically
What You Can Do
You'll systematically troubleshoot wireless connectivity problems by guiding structured data collection, analyzing root causes, and validating fixes. This skill walks you through diagnostic interviews, signal analysis, device troubleshooting, and performance optimization—turning vague WiFi complaints into actionable remediation steps with documented changes and recovery procedures.
Features
Asks targeted questions to systematically gather network topology, device types, symptoms, and environmental factors
Interprets WiFi signal metrics and identifies interference sources affecting performance
Steps through authentication, DHCP, IP configuration, and driver issues on client devices
Analyzes speed test results, latency, and packet loss to identify and prioritize root causes by impact
Compares router, adapter, and client settings against security and performance best practices
Produces step-by-step recovery procedures with rollback plans for configuration changes
Suggests channel selection, placement, QoS settings, and technology upgrades based on environment
Creates audit trail of diagnostics, root causes, actions taken, and verification results
Example Output
Example 1: Remote Help Desk Scenario
- 🔍 DIAGNOSTIC SUMMARY
━━━━━━━━━━━━━━━━━━━━━━━━━━
Symptom: Office WiFi slow on 2nd floor
Environment: 2-story commercial building, 50+ devices
Signal Strength: -75 dBm (marginal)
Interference: 3 nearby networks on same channel (2.4 GHz)
- ✅ ROOT CAUSE (Ranked by Impact)
1. Channel congestion — Router on 2.4 GHz Ch. 6, overlapping with 3 neighbors
2. Signal attenuation — Router in basement, 2 floors + metal studs reduce range
3. Client device issue — Older laptop WiFi card poor band steering
- 🔧 REMEDIATION STEPS
1. Switch router to 5 GHz band (channel 149) — Reduces interference by 90%
2. Relocate router to central location on 2nd floor — Improves signal 15+ dB
3. Update laptop WiFi drivers — Enables 802.11ac support
✔ Verification Checklist
□ Signal strength now -50 dBm or better on 2nd floor
□ Speed test shows 100+ Mbps downstream
□ No interference from neighboring networks
Example 2: On-Site Diagnostics
- 📋 DATA COLLECTION
━━━━━━━━━━━━━━━━━━━━━━━━━━
Router Model: TP-Link AX6000
Firmware: v1.2.8 (outdated, v1.4.2 available)
Antenna Config: Both antennas vertical (suboptimal)
SSID Broadcast: Disabled (client discovery issue)
Band Steering: Off (forces 2.4 GHz for older devices)
- 🚨 CRITICAL FINDINGS
• WPA2 only — upgrade to WPA3 for security
• Guest network using WEP encryption — immediate vulnerability
• Channel 13 (not supported in US) — causes certification issues
- ✅ ACTION PLAN
1. Firmware update → v1.4.2
2. Configure band steering (5 GHz preferred)
3. Migrate guest network to WPA2-PSK
4. Set channel to 1, 6, or 11 (2.4 GHz) or 36-165 (5 GHz)
5. Enable SSID broadcast
