Week 15: Final LAN Build and Portfolio Submission

Lesson recap

This is the week everything you've practiced converges into one working network. Assess the hardware, confirm the drivers, run the cables you planned last week, configure the router, assign IPs, ping everything, transfer a file, and submit the portfolio that proves it. The grade is the portfolio — not the network. A working LAN with sloppy documentation scores worse than a slightly flawed LAN with a perfect troubleshooting log. The skill we're really testing: can you build something AND prove you built it, the way you'd have to on day one of a real IT job.

Learning goals

Assess provided computers and router
Check network adapters and drivers
Connect the physical LAN
Verify IP information on each device
Test pings and file transfer across the LAN
Submit the final portfolio

Key terms

Hardware Assessment

Inspecting equipment before build — power, ports, labels, condition.

Network Driver

Software that makes a network adapter work — check Device Manager.

Router Configuration

The router settings used for the build (IP, DHCP scope, SSID, password).

Connectivity Test

A ping or file-transfer test to verify the LAN works end-to-end.

Technical Portfolio

The final collection of evidence, reports, and reflections that you submit.

Pro tips from the instructor

★Take screenshots BEFORE you tear anything down. You will not get a chance to re-run the test for the portfolio.
★If a ping fails, follow the OSI ladder: link light → IP → mask → gateway → router → DNS. Don't guess.
★Write the troubleshooting log live, not from memory. Time-stamped notes are gold; reconstructions are fiction.

0/1

After the official tests pass, intentionally unplug one cable and time how fast the team diagnoses the failure. That's the skill employers pay for.
