@ayesha86664

Hi there! You are troubleshooting persistent LAN issues, and the real challenge is identifying intermittent drop-outs and throughput bottlenecks while keeping operations running — that is exactly where most network audits fall short. I recently resolved a similar office network problem, diagnosing switch misconfigurations and subtle cabling faults that were causing random disconnects, and implemented corrective actions that restored stable, high-speed connectivity. I delivered full documentation and preventive recommendations to avoid future disruptions. I will analyze your LAN using packet captures, switch diagnostics, and monitoring tools, identify root causes, apply precise fixes, and provide a detailed report with verification of restored performance. Check our work: https://www.freelancer.com/u/ayesha86664 Do you want me to include both on-site and remote troubleshooting options for maximum flexibility? I am ready to start — just say the word. Best Regards, Ayesha

Please send me a message so that we can discuss more. Thanks

@ronaldoluiza

Hi! I have experience troubleshooting LAN environments and resolving issues like intermittent connectivity, slow throughput, and random disconnections. Based on your description, this could be related to misconfiguration (STP/VLAN/DHCP), faulty cabling, or network congestion. My approach would be: • Perform a full diagnostic (traffic analysis, device health, topology review) • Identify root causes using tools like Wireshark and switch/router diagnostics • Apply fixes (configuration adjustments, segmentation, or hardware validation) • Verify stability with post-fix testing • Provide a clear report with findings and prevention recommendations Estimated time: 8–12 hours depending on network size and complexity Rate: €40/hour Let me know if you can share more details about your network (number of devices, switch models, topology), and I can refine the estimate. Looking forward to helping you stabilize your network. Do you have managed switches? Is spanning tree enabled? Any recent changes before issues started?
