A labeled home-network baseline map
Guided practice · Network Foundations
Map a home network baseline
Identify the devices and connection boundaries in a home network before troubleshooting it.
Outcome summary
Know what success looks like before you begin
Save the completed a labeled home-network baseline map together with the evidence recorded during each field check.
- I identified the internet-entry and local routing roles.
- I grouped client devices without recording sensitive identifiers.
- I recorded a timestamped local and internet access baseline.
Stop before factory-resetting, rewiring, or changing provider equipment unless current settings and cable positions are documented.

Lab brief
Know the problem and the evidence you need
A home network has several phones, computers, smart devices, a router and an internet connection, but no one has recorded how they connect.
A labeled home-network baseline map
Create a simple baseline map that separates the client device, local network equipment and internet provider boundary.
A simple map of modem, router, access points, devices, and connection paths makes later Wi-Fi and internet tests comparable instead of guesswork.
Safety and setup
Prepare before changing anything
Have this ready
- Do not unplug, reset or reconfigure the router during this lab.
- Use generic device labels in your notes; do not publish MAC addresses, public IP addresses or Wi-Fi passwords.
- Have permission from the network owner before inspecting connected-device lists.
Field checks
0 of 5 checks completeRun the lab
Complete one check at a time. Record the evidence before moving on.
Interpret results
Match the evidence to the next action
If you seeNext action
One device combines modem, router and Wi-Fi roles
Treat it as several logical boundaries even though it is one physical box.
Wired devices work but wireless devices do not
Focus later tests on Wi-Fi signal, bands, authentication and access-point behavior.
No device has internet access
Separate local gateway access from the provider connection before changing client settings.
Choose the next action
Use the baseline map to choose the narrowest next lab: signal and bands, IP and gateway, DNS, or connected-without-internet triage.
