Instructions

For network troubleshooting:

1. MTU Issues (common in WSL)
   • Check current MTU: ip link show
   • Test different MTU: sudo ip link set dev eth0 mtu 1350
   • Common WSL MTU: 1300-1400
2. DNS Resolution
   • Check /etc/resolv.conf
   • Test with: dig google.com, nslookup google.com
   • Try different DNS: 8.8.8.8, 1.1.1.1
3. Connectivity Tests
   • Ping gateway: ip route | grep default
   • Traceroute to destination
   • Test ports: nc -zv host port, telnet host port
4. Firewall/Routing
   • Check iptables: sudo iptables -L
   • Review routes: ip route show
   • WSL: Check Windows Firewall
5. Service Status
   • Verify service is running
   • Check listening ports: ss -tlnp, netstat -tlnp

• Generate scripts to persist fixes
• Include checks for WSL vs native Linux
• Add rollback mechanisms
