Wi-Fi & Networking
Wi-Fi troubleshooting checklist
Slow Wi-Fi does not always mean the router needs to be replaced. A few checks can show whether the problem is one device, Wi-Fi coverage, the router, or the internet connection itself before you spend money on new equipment.
1. Find out how much is affected
Check another phone, laptop, or streaming device. If only one device is having trouble, start with that device. If everything is slow or offline, the router, modem, cabling, or internet service is more likely to be involved.
2. Compare Wi-Fi close to the router
Test from the same room as the router, then compare that with the problem area. A connection that works well nearby but falls apart across the house points toward coverage, interference, placement, or a mesh/access-point issue rather than the internet service alone.
3. Check the simple physical connections
Make sure the modem, router, and any separate network equipment have power and that Ethernet or coax connections have not been loosened. Look for obvious warning lights, but use the equipment provider's documentation because light meanings vary by model.
4. Restart equipment without factory-resetting it
A normal restart can clear temporary problems. Use the device's restart option or power it off and back on according to the provider or manufacturer's instructions. Do not press a recessed reset button unless you intentionally want to erase the configuration and have the information needed to set it up again.
5. Check whether the internet provider is the problem
If every device is affected even near the router, check the provider's official app, status page, or support line for an outage. If you have a separate modem and router, an internet-service problem can make healthy Wi-Fi look broken because devices remain connected to the wireless network but cannot reach the internet.
6. Reconnect one problem device
If the issue is limited to one device, confirm airplane mode is off, restart the device, and reconnect to the correct Wi-Fi network. Forgetting and rejoining a network can help in some cases, but make sure you know the correct Wi-Fi password before removing the saved connection.
7. Look at router placement before buying more hardware
Routers generally work better in a central, open location than inside a cabinet, behind large electronics, or at one extreme end of a building. Multi-level homes, dense walls, long distances, and detached spaces may need better placement or additional access points or mesh equipment.
8. Compare the result you get with what you actually need
A speed test can be useful, but one number does not diagnose the network. Compare tests near the router and in the problem area, note whether devices disconnect, and record when the issue happens. Those details are usually more useful than repeatedly replacing equipment without isolating the cause.
Before you factory-reset the router
A factory reset can erase the Wi-Fi name, password, internet settings, mesh configuration, parental controls, port settings, and other custom configuration. If the router is supplied by an internet provider or supports important business devices, confirm what will be lost and how it will be restored before resetting it.
