Supports checking another device to establish scope, checking router reachability, and examining DNS when local connectivity exists but access still fails.
Experiment 03 · 5–7 minutes
Connected, but offline
Test one segment at a time, keep ruled-out causes visible, and verify one bounded correction on a fictional laptop.
Fictional diagnostic pathTest one boundary at a time.

About this experiment
Use it: Read the path, choose the next test, and keep each deterministic result in the reasoning record.
Reasoning rule: Establish scope, test one unresolved boundary, change one thing, then repeat the original failing path.
Boundary: This authored simulation runs no commands, inspects no device, and is not a repair tool.
One symptom · one path · one change at a time
Why can one laptop appear connected while named websites still fail?
This laptop says it is connected, but named websites fail. Other devices on the same Wi-Fi work. Test outward from the laptop without changing the network first.
Fictional request pathOne laptop · one failing request
Test outward. Change nothing yet.
- Laptopconnected
- Routeruntested
- Internetuntested
- DNSuntested
- Websitefails
Other devices on the same Wi-Fi load named websites.
Which test checks the nearest unresolved boundary?
Other devices work. Test this laptop before changing shared equipment.
Reasoning record1 evidence · 1 hypotheses ruled out
- ScopeOther devices load named websites
The main case is device-specific, not network-wide.
- Network-wide outageruled out
Other devices working makes this unlikely in the main case.
- Laptop Wi-Fi linkuntested
A local-router response can rule this out.
- Upstream internet routeuntested
An external-address response can rule this out.
- Laptop name-resolution settinguntested
A failed name test with a working IP path can support this.
Sources and boundariesThe procedure is sourced. Every result is authored.Open details
Microsoft guidance supports establishing scope with another device, checking the path before broad changes, and using Automatic (DHCP) for router-provided IP and DNS settings. It does not supply this fictional failure or validate the learning method.

Supports the fictional correction that returns IP and DNS assignment to the router-provided Automatic (DHCP) setting.
Limitations and open questions
- Every device, result, address, setting, and website in the exercise is fictional and authored.
- The instrument runs no commands, reads no network state, and performs no repair action.
- Real connectivity failures can have causes not represented in this deliberately narrow path.
- Microsoft guidance informs the procedure language; it does not validate this learning method or guarantee a diagnosis.
- The evaluator checks authored actions and constraints. It does not infer causes, generate tests, or adapt automatically.
