Symptoms your readers will recognise immediately. Keep it short — they're already frustrated. Use the actual error messages, link colours, or behaviour they're seeing.

List every observable indicator: lights, error codes, command output, app messages. Each symptom should be a search term someone might Google verbatim.

Step-by-step process to confirm the root cause. Include the exact commands (ping, tracert, mtr, nslookup, ip route, show ip interface brief) and what good vs bad output looks like.

The fix that worked, with every config line, every menu path, every screenshot. No hand-waving. Include rollback steps.
