Comprehensive Network Troubleshooting & Maintenance

@amirasmbarakat

Hello, I can diagnose and stabilize your production network, resolving disconnections, poor throughput, and identified security gaps. I have hands-on experience with multi-vendor networks (Cisco, Juniper, Fortinet), packet analysis (Wireshark), and physical link troubleshooting. I’ll provide root-cause findings, optimized/backed-up configs, verified performance improvements, and a short security hardening checklist. Ready to start immediately with console or remote access. Thanks

Hi, This is exactly the kind of production-network issue I handle regularly. I’m a senior network engineer with 7+ years of experience troubleshooting and stabilizing enterprise environments across Cisco, Fortinet, and multi-vendor networks. I’ve led root-cause analysis for intermittent disconnections, low throughput, and security gaps in live production networks. My diagnostic approach: Baseline current performance and error counters Review device configurations (routing, switching, firewall policies) Validate physical links and interface health Packet captures (Wireshark) to identify drops, latency, or misbehaving flows Fix and optimize configurations (with full backups) Post-change verification and performance comparison Deliverables you’ll get: Clear root-cause report per issue Optimized and backed-up configurations Verified performance improvements A short hardening checklist to prevent recurrence I’m comfortable working with live production environments and can start immediately using your preferred handover order. Estimated turnaround: initial findings within 24–48 hours, depending on environment size. Rate: ₹750/hour Happy to discuss your topology and priorities before starting. Best regards, Ahmed

I have knowledge and experience of networks from 3-tier network design to todays data centers. I have already troubleshooted the kind of issues in networking as you described.
