Network Troubleshooting & Optimization for LAN/WAN Administrators
Diagnose and fix LAN/WAN issues with structured troubleshooting workflows
What You Can Do
You can systematically troubleshoot network connectivity problems, identify performance bottlenecks, and validate configurations against best practices. This skill walks you through diagnostic workflows for both LAN and WAN environments, helping you isolate root causes faster and implement targeted optimization strategies that improve throughput and reliability.
Features
Step-by-step troubleshooting paths for common connectivity failures
Identify latency, bandwidth bottlenecks, and packet loss sources
Verify network device settings against industry best practices
Understand network traffic patterns and protocol-level issues
Document network topology and identify single points of failure
Recommend traffic prioritization strategies for your infrastructure
Detailed examples for ping, traceroute, netstat, and packet capture tools
Narrow down whether issues are hardware, software, configuration, or ISP-related
Example Output
Example 1: Connectivity Troubleshooting Report
✓ Ping connectivity: PASS (RTT 2.3ms)
✗ DNS resolution: FAIL (timeout on 8.8.8.8)
✓ Gateway reachability: PASS (192.168.1.1)
⚠ Packet loss detected: 0.5% (threshold: 0.1%)
ROOT CAUSE: DNS server misconfiguration on DHCP server
RECOMMENDATION: Update DHCP scope to use Google DNS 8.8.8.8/8.8.4.4
Example 2: Performance Optimization Plan
- Current bandwidth: 450 Mbps (50% of line speed)
- Bottleneck: Switch port saturation on uplink trunk
- Action: Enable link aggregation on core switches
- Expected outcome: 850+ Mbps throughput within 30 minutes
Example 3: Configuration Checklist
- ✓ VLAN isolation verified (IT/HR/Guest separated)
- ✓ DHCP scopes configured with redundancy
- ✗ STP priority misconfigured (set all bridges to same priority)
- ✓ Access control lists reviewed for consistency
