When to Use

User needs help with internet connectivity: comparing/switching providers, diagnosing speed issues, managing mobile data abroad, optimizing for gaming/streaming, or troubleshooting connection problems.

Core Rules

1. Diagnose Before Recommending

Run diagnostics first — don't assume the problem. Check:

  • Speedtest vs contracted speed (flag if <70%)
  • Packet loss and jitter
  • DNS resolution time
  • Whether issue is local, ISP, or destination

2. Provider Comparison Must Include Hidden Costs

When comparing providers:

  • Show price AFTER promotional period ends
  • Include early termination penalties
  • Calculate total 24-month cost, not monthly
  • Check coverage at user's exact address first

3. Mobile Data: Verify Before Activating

Before recommending eSIM/roaming:

  • Confirm device eSIM compatibility
  • Check destination country coverage
  • Compare local SIM vs international eSIM vs roaming
  • Alert user to data caps and throttling thresholds

4. Performance Claims Need Verification

For gaming/streaming optimization:

  • Measure actual latency to game servers, not generic ping
  • QoS changes require router admin access
  • Bufferbloat is real — test with loaded connection
  • "Faster DNS" rarely matters for speed, only for reliability

5. Keep History for ISP Disputes

Log incidents with timestamps:

  • Date, time, duration of outages
  • Speedtest results during issues
  • Steps already attempted
  • This evidence helps when escalating to ISP

Common Traps

  • Recommending provider switch without checking contract end date → user pays penalty
  • Assuming WiFi issue when it's ISP problem → wasted troubleshooting
  • eSIM purchase without verifying phone support → money lost
  • QoS advice without knowing router model → unusable instructions
  • Comparing speeds without noting technology (fiber vs cable vs DSL) → misleading

Scope

This skill handles:

  • ISP selection, comparison, and contract analysis
  • Connection diagnostics and troubleshooting
  • Mobile data management (eSIM, roaming, tethering)
  • Performance optimization for specific use cases

This skill does NOT handle:

  • WiFi-specific issues (channel optimization, security) → use wifi skill
  • Network infrastructure setup (routers, mesh systems)
  • VPN configuration or privacy tools
