What is Send Listy?
Create and organize your own lists. Start here, add or remove items, check off what matters, and share selections via WhatsApp or iMessage.
Make this checklist your own. Add what you need, edit what you like, and remove anything that doesn’t fit.
Identify the problem
Work out whether this is one-device trouble, a wireless signal issue, or a wider internet outage.
Step 1Test a second device ›
Try the same Wi-Fi network with another phone or computer. If only one device fails, focus on its settings; if several fail, focus on the router or provider.
Step 2Check the modem and router lights ›
Compare indicator lights with the device manufacturer’s guide. Note any warning light, but do not assume all models use the same colors.
Step 3Inspect cables and power safely ›
Check that cables are seated and equipment has power. Do not open devices, touch damaged cables, or work on electrical equipment.
Do not unplug or bend fiber-optic connectors unnecessarily. Fiber cables can be delicate.
Run low-risk connection checks
Use reversible checks and a controlled restart before changing advanced network settings.
Step 4Restart equipment when appropriate ›
If the connection affects the household, follow your provider or manufacturer’s restart sequence. For separate devices, the modem generally comes online before the router. Restarting briefly disconnects everyone.
Step 5Test the connection after restarting ›
Wait for the equipment to finish starting. Reconnect and try more than one trusted website or app to distinguish a general outage from a single-service problem.
Step 6Toggle Wi-Fi on the affected device ›
Confirm Airplane Mode is off, switch Wi-Fi off and on, and select the intended home network. Avoid changing router settings at this stage.
Step 7Forget and reconnect if you know the password ›
Only forget the saved network when the password and required sign-in details are available. Rejoin it and check that the correct network is selected.
Make sure you know the Wi‑Fi password before forgetting the network.
Step 8Check distance and signal strength ›
Move closer to the router for a brief test. If signal improves, inspect placement or interference; consider a supported alternate Wi-Fi band if available.
Confirm the outcome and escalate
Use evidence from your tests to decide whether to check device support or contact the internet provider.
Step 9Check the provider’s outage information ›
Use mobile data or another connection to check your internet provider’s service-status page and any account notices.
Step 10Run device-specific diagnostics ›
For a single affected device, use official operating-system troubleshooting. Save any custom VPN or network settings before making changes.
Step 11Avoid resetting the router to factory defaults ›
A factory reset can erase network names, passwords, and provider configuration. Do not use it as a routine step; consult the manufacturer or provider first.
Do not factory-reset the router unless you know the Wi‑Fi/router setup details and, where required, your internet provider credentials.
Step 12Contact technical support with your findings ›
Record which devices failed, the light pattern, restart results, and any error message. Share these observations with your provider or router manufacturer without revealing passwords.
Complete Guide
Complete guide to home Wi-Fi troubleshooting
Follow a safe diagnostic order for common home Wi-Fi problems. Identify whether one device, the wireless signal, the router or the internet service is affected before changing settings.
This guide supplements the interactive tasks shown above. Add or remove items based on your real circumstances; the list is a starting point rather than a universal requirement.
Describe the failure accurately
A device can be connected to Wi-Fi but unable to reach the internet, or the Wi-Fi network may be missing entirely. Test the same task on another device to locate the problem.
Start with reversible checks
Check airplane mode, Wi-Fi status and the selected network. Look for local service outages and read router indicators using the manufacturer’s guide.
Restart without deleting settings
If appropriate, restart the device and networking equipment in the manufacturer’s recommended order. Avoid factory resets as an early step because they can erase custom settings.
Check range and software
Test nearer the router, consider obstacles and review relevant system updates. Change one variable at a time and note which action affected the result.
Escalate with useful evidence
If several devices fail, record indicator status and the times of failure before contacting the provider. Avoid sharing Wi-Fi passwords, admin credentials or private network screenshots publicly.
How to use the checklist groups
Move through the existing groups in the checklist, such as Identify the problem, Run low-risk connection checks, Confirm the outcome and escalate. Complete urgent or time-sensitive steps first. Use item notes for context, and keep your own copy in Send Listy for personalized additions and progress tracking.
Final review and customization
Before finishing, revisit any unchecked item to decide whether it is required, not applicable or waiting on another person. Record a reminder for time-sensitive follow-up rather than marking work as complete prematurely. Keep personal documents and account details outside shared public notes.
Frequently asked questions
What if only one device cannot connect?
Focus first on that device’s Wi-Fi setting, saved network and software.
What if every device is offline?
Check the router/modem and provider outage information before changing individual devices.
Should I factory-reset the router?
Not as a first step. It can erase network settings and disconnect connected devices.
Do Windows steps apply to phones?
Not directly. Use operating-system-specific help for each device.
Can I share screenshots for troubleshooting?
Redact passwords, public IP details and other private information before sharing.
