Additionally, I'm proficient in troubleshooting tools like Wireshark, NetFlow and known CLI commands that could be useful in identifying potential misconfigurations. Beyond problem-solving capabilities, I'm known for timely project delivery and an unwavering commitment to customer satisfaction; not only resolving the issue but also ensuring future stability. If chosen for this task, you can expect utmost professionalism, transparency, adherence to best practices and concise documentation of each step taken along the way. Let’s get started with a 24-hour continuous troubleshooting session – full proof of my skillset to effectively restore your network stability.

Hi there, I understand intermittent workstation dropouts and can quickly identify root cause and restore stable network service with remote access and logs , confident I can meet your 24‑hour acceptance criteria. - Perform packet capture (Wireshark), NetFlow review and live interface statistics to reproduce dropouts - Audit switch/router/DHCP/DNS configs and cabling; run vendor CLI checks on Cisco switches/gateway - Apply corrective changes (firmware, QoS, spanning-tree, DHCP leases) and test with live traffic - Deliver concise report + exact change log and 24‑hour validation plan Skills: ✅ Network Engineering ✅ DHCP ✅ packet capture / Wireshark ✅ switch/router configuration & vendor CLI ✅ Network Monitoring / NetFlow and log analysis ✅ Network Security / troubleshooting and hardening Certificates: ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ cPanel® & WHM Certified CWSA-2 I can start immediately and deliver initial findings within hours; Please confirm: can you provide remote admin credentials for the gateway and one affected PC, plus recent switch logs and topology (VLANs, trunking, PoE), or do you prefer I start with non‑intrusive diagnostics only? Best regards,

Alright, let’s talk like adults… and a little like late-night satire. Right now your network is doing that classic drama-queen move: phones chilling, IoT living their best life, and the office PCs? “No connection, habibi.” That’s not bad luck — that’s a misconfig hiding somewhere and laughing at us. I’m a network engineer. I don’t reboot and pray. I investigate. Here’s how I’ll hunt the culprit: • Check switch/router configs like a forensic accountant • Review DHCP/DNS scopes for conflicts, lease chaos, or ghost IPs • Pull interface stats (errors, drops, flaps) • Run packet captures with Wireshark to see who’s lying on the wire • Validate cabling, VLANs, ARP tables, and routing paths • Fix it cleanly, then document everything like a crime report After repairs, we stress-test with real traffic and monitor for 24+ hours. If a single PC sneezes offline, we’re not done. Tools? Wireshark, NetFlow, vendor CLI, logs — whatever gets the truth. I don’t guess. I prove. You give me access. I give you a network that behaves like an adult. Let’s stop the drama and make your LAN boring again.

I have hands-on experience managing networks and troubleshooting intermittent connectivity issues in ISP and office environments. My background includes diagnosing DHCP conflicts, routing misconfigurations, firewall rule conflicts, switch port errors, and bandwidth instability. Because I operate and maintain network infrastructure daily, I approach troubleshooting methodically rather than through trial and error. I understand how to isolate faults across Layer 1–7 OSI layer rules, and I am comfortable working with gateway devices, managed switches, and endpoint systems remotely.

Hi, I’m an experienced Network Engineer with strong hands-on expertise in diagnosing and resolving intermittent network connectivity issues—especially those affecting wired workstations while other devices remain stable. I will methodically analyze the problem using interface statistics, configuration reviews, DHCP/DNS validation, packet capture (Wireshark), and switch/router CLI diagnostics to identify the root cause. Once identified, I’ll implement corrective changes, validate stability with live traffic tests, and provide clear documentation of what was fixed. I’m comfortable working fully remotely and can start immediately. With proper access to the gateway, switches, PCs, and logs, I’m confident I can restore stable connectivity and meet your 24-hour uptime acceptance criteria. Let’s get this resolved quickly and cleanly. Best regards, Sitaram Banskota System & Network Engineer

i can fix the network issue in 2 days after providing remote access and network topology and ip addresses schema

@babluk92

I propose a structured, root-cause–driven troubleshooting approach to identify and permanently resolve the intermittent network connectivity issue.

@Jomser777

Hello! My name is Jose and I'm placing my bid here in order to supply my services and provide you a solution for your reported issue. I am an experienced network engineer specializing in Cisco products (routers, switches and access points) with a CCNA certification but also have had hands-on experience with Aruba switches and access points, Fortinet firewalls, VoIP systems and so on. I also have more than 5 years of experience working in the IT industry as an IT Specialist, Network Engineer and VoIP Engineer. If you are interested, kindly reach out to me and we can discuss this matter further. Also, kindly provide for me the scope of the task at hand (the size of the project, how many workstations and network devices involved, device types that come into play, troubleshooting tools available for the task and so on).

Hi! I see you are having intermittent connectivity issues, and I am confident I can identify the root cause quickly. I am a Telecommunications Engineer and currently work as a NOC Engineer at 'Silknet' (the leading ISP in Georgia). For over a year, I have been managing fixed networks, troubleshooting complex connectivity drops, and ensuring stable service for thousands of users. I can provide proof of my professional background upon request. In my daily work, I am highly proficient with: 1. Monitoring & Analysis: Zabbix and Grafana for real-time traffic monitoring. 2. Remote Management: SecureCRT for accessing and configuring various Switches, Routers, and OLTs. 3. Protocol Analysis: Identifying issues like DHCP/DNS misconfigurations or hardware-level failures. I am new to this platform, which is why my portfolio currently shows my university-level projects with Arduino, ESP32, and sensors. However, my professional daily career is strictly in Network Engineering. I am looking for my first successful project here and I am highly motivated to solve your problem. I will use remote access to perform a deep dive into your network logs and traffic to find exactly where the drop-outs occur. Please trust me with this task, and I guarantee a professional, stable solution and a clear final report. Ready to start immediately!
