When Your Network Stops Making Sense
Most people troubleshoot networks by guessing. We teach you to read what the infrastructure is actually telling you — packet by packet, layer by layer.
See What You'll Learn
We Start Where Google Searches End
You've already tried restarting the router. You've checked the cables. Everything looks fine on the surface, but users are still complaining about slowness, dropped connections, or intermittent failures.
That's where most troubleshooting stops — and where our program begins. Because network problems rarely announce themselves clearly. They hide in timing issues, protocol mismatches, and traffic patterns that only reveal themselves when you know what to look for.
We built this program around real scenarios that kept us up at night. The ones where standard diagnostics pointed to nothing wrong, but something definitely was. Those are the problems that taught us how networks actually break — not how textbooks say they should.
Problems That Sound Familiar
The Intermittent Application Failure
Works perfectly for hours, then suddenly stops responding. Nothing in the logs. No error messages. Just silence. And then it comes back on its own.
The Slow File Transfer Mystery
Local transfers fly. Cross-subnet transfers crawl. Bandwidth tests show plenty of capacity. Users are frustrated. You're running out of things to check.
The One Device Problem
Everything connects fine except that one laptop. Or phone. Or printer. Same network settings as everything else. Different result. No obvious reason why.
How We Actually Solve These
Not through magic or expensive monitoring tools. Through systematic observation of what the network is already telling you — if you know how to listen.
Establish a Baseline
You can't identify abnormal behavior without knowing what normal looks like. We teach you to document traffic patterns, timing characteristics, and protocol behaviors when things are working.
Isolate Variables
Network problems involve multiple layers and countless moving parts. The skill is narrowing down which layer is actually causing the issue — not just where symptoms appear.
Read the Conversation
Network communication follows predictable patterns. When those patterns break, the packets themselves tell you what went wrong — timing gaps, unexpected flags, missing responses.
Verify the Fix
Symptoms can disappear temporarily while root causes persist. We show you how to confirm you've actually solved the problem, not just masked it or gotten lucky.
Why Packet Analysis Changes Everything
- You stop guessing and start confirming what's actually happening on the wire
- You see protocol violations that devices don't report in their status displays
- You identify timing problems that explain intermittent failures
- You catch configuration mismatches that standard tools don't flag
- You understand why "everything looks normal" when it clearly isn't
This isn't about memorizing Wireshark filters. It's about developing the analytical mindset to interpret what you're seeing and connect it to real-world symptoms.
What You'll Work With
We focus on tools you'll actually use in production environments — not theoretical exercises with proprietary platforms you'll never see again.
Wireshark
The standard for packet analysis. We teach you to use it effectively, not just capture everything and hope.
Command Line Tools
Ping, traceroute, netstat, and tcpdump. Simple utilities that reveal network behavior when used with purpose.
Protocol Analyzers
Understanding how to decode and interpret protocol conversations at the packet level.
Traffic Pattern Analysis
Identifying normal versus anomalous behavior through systematic traffic observation.
Diagnostic Scripts
Custom testing approaches for specific scenario types that standard tools don't address.
Documentation Methods
Creating reference materials that actually help during midnight troubleshooting sessions.
Who's Teaching This
Rohan Deshmukh spent twelve years maintaining enterprise networks where downtime measured in minutes cost real money. He learned troubleshooting the hard way — through 3 AM calls, angry users, and problems that didn't appear in any manual.
This program came from keeping notes on what actually worked. Not the theoretical approach from certifications, but the practical methods that consistently identified root causes under pressure.
More About Our ApproachNext Program Starts February 2026
We run small cohorts because effective troubleshooting training requires working through real scenarios together. You'll have direct access to instructors and the ability to bring your own network problems for analysis.
Sessions are structured around practical exercises. You'll spend more time looking at actual packet captures and diagnosing realistic issues than listening to lectures.
