- Companion workbook + 12-checklist pack + bonus resources
- A 12-ticket Real Network Support Ticket Lab + full troubleshooting framework
- Instant digital download
A practical, 20-chapter networking course built for first-line IT Support — not a CCNA-style engineering course. Learn exactly what you need to isolate a real fault, through real Northbridge Solutions Ltd tickets.
No binary subnetting. No VLSM. No CIDR maths. Just the one repeatable path every connection actually takes — and a clear way to work out which link on it has failed.

Networking Courses Either Drown You in Theory, or Never Actually Teach You Anything Useful
Most first-line technicians either avoid networking entirely, or start a CCNA-style course that buries them in subnetting maths they'll never actually use on a real shift.
Binary Subnetting You'll Never Actually Need
Most networking courses teach engineering-depth maths first-line support genuinely doesn't need — you end up able to calculate a subnet, but no better at solving “the internet's not working.”
No Repeatable Way to Actually Troubleshoot
Without one consistent framework, every “no internet” ticket feels like starting from scratch — guessing at fixes instead of narrowing the fault in order.
Terminology That Never Quite Clicks
IP addresses, gateways, DHCP and DNS get defined in isolation, so the terms never connect into one picture of what's actually happening when a connection fails.
From “I Just Restart the Router” to “I Know Exactly Which Link Just Failed”
By the end of the course, you'll have worked a complete 12-ticket Ticket Lab using one repeatable framework — reading evidence, narrowing the fault, and only then reaching for a fix.
- A working mental model — the six-link path every connection actually takes, from device to destination
- Confident use of ipconfig, ping, nslookup and tracert, knowing exactly what each result does and doesn't prove
- The ability to tell a Wi-Fi-specific fault apart from a wider network or internet fault, in one test
- A complete five-step framework for “no internet,” applied to VPNs, printers and shared resources too
- A genuinely useful escalation note format, and the judgement to know when a fault is beyond first line
Course Curriculum
Twenty chapters, built to be worked through in order — each one building on the six-link connection path introduced in Chapter 1.

Frequently Asked Questions
No, and it's deliberately not. This course teaches exactly what first-line IT Support needs to isolate a network fault logically — no binary subnetting, VLSM or CIDR calculations. If you want network-engineering depth later, certifications like CompTIA Network+ pick up roughly where this course leaves off.
You'll receive five PDF files: the course ebook, the practical workbook, the checklist pack, the bonus resources pack, and the final assessment with answer key — instantly after checkout. When you pass the assessment, your certificate of completion is issued on Learn.GigLad.com.
No. It's written for beginners with little or no formal networking knowledge, and for anyone applying for Help Desk, Service Desk or Desktop/Remote Support roles who finds networking terminology intimidating.
No — this course works perfectly on its own. It builds on Help Desk Technician for Beginners and complements Microsoft 365 Support, IT Support for Remote & Hybrid Workplaces, and IT Support Interview & Technical Assessment Preparation, going deeper into networking than any of them attempt to.
