RouterEntry · Sources checked · How we write our guides
First check whether your exact router still receives security updates, whether it meets your needs, and whether the problem actually comes from the router.
1. Confirm the model and support status
Read the model and hardware revision from the label. Find that exact version on the manufacturer’s official support site, including any end-of-support notice. Provider-branded equipment may follow the provider’s update process. A recently downloaded manual is not proof that security updates are still supplied.
If updates have ended, plan a move to supported equipment. Installing the last available firmware does not restore an ongoing support commitment. Do not install firmware for a similarly named model or a different hardware revision.
2. Establish what is limiting the connection
Compare performance near the router, in the problem room, and over Ethernet where possible. If only a distant room is affected, placement or a coverage addition may solve it. If the wired connection is also poor, check provider service, cables, and the computer before blaming the router.
| Reason to investigate replacement | What to verify |
|---|---|
| Security updates have ended | The notice applies to your exact model, revision, region, or provider variant. |
| A port limits a faster plan | The router’s WAN and LAN port specifications, cable link, and your device adapter. |
| Frequent instability remains | Supported firmware, ventilation, cables, power supply, provider status, and a repeatable failure pattern. |
| You need features the router lacks | The new model supports them without an unexpected subscription or incompatible operating mode. |
3. Check the total change, not just the box
- ISP compatibility: determine whether you need a router, a modem-router, or a router connected to an existing modem/ONT.
- Services: ask about required settings and any telephone or television dependencies.
- Coverage: plan placement and any extra access points or mesh nodes.
- Devices: confirm that older and smart-home devices can join the intended Wi-Fi configuration.
- Ongoing costs: check which management, security, or parental-control features are subscription services.
4. Make the change reversible
Record the settings you are permitted to access and keep the old equipment until the new network works. Store credentials securely, away from a shared troubleshooting sheet. Exported configuration files may contain secrets and usually cannot be transferred between unrelated models.
Set up the supported replacement using its official instructions, update firmware, and choose a separate admin password. Check work devices, printers, smart-home equipment, and provider services. The home-network checklist gives you a repeatable before-and-after record.
Still deciding?
Use our coverage comparison if the issue is confined to part of the home. We do not apply a fixed replacement schedule or claim that buying a newer Wi-Fi generation will make every existing device faster.
