Your router does not suddenly quit the day its manufacturer stops publishing firmware updates. If the hardware remains healthy, it can continue doing its ordinary job: connecting PCs, consoles, phones and other home devices to the internet. That is precisely what can make an unsupported router easy to overlook. A stable connection can feel like proof that everything is fine.
It is not proof of that. Firmware support matters because newly discovered security flaws may need a fix. Once updates have stopped, a router can keep working while losing its most reliable path to receiving those fixes. There is no need for panic and no basis for assuming an unpatched router has already been compromised. But it is sensible to treat the end of support as a security and replacement-planning issue, rather than a reason to keep using the device indefinitely because the Wi-Fi still reaches the sofa.
For a household with a gaming PC or console, this is part of the unglamorous infrastructure behind every download, update and online session. Digital access is increasingly central to games and services, as seen in changes such as Xbox’s Disc-to-Digital rollout. That does not make every older router unsafe, nor does it mean a new one must be bought on a rigid schedule. It does mean the router deserves the same occasional maintenance attention as the devices plugged into it.
What firmware support actually changes
Firmware is the software that runs on the router itself. It governs the device’s operation and provides a route for its maker to address problems after sale. When a manufacturer releases new firmware, it may include security repairs, among other changes. When those releases end, the router continues to run the version it already has, but flaws found later may remain unresolved.
The practical risk is not that an unsupported router has a built-in shutdown date. It is that its security posture can become less defensible over time. Attackers may target vulnerable routers in bulk, potentially using compromised devices to relay malicious traffic or to join a larger remotely controlled collection of devices without the owners knowing.
That distinction is worth keeping clear. “No longer updated” is not synonymous with “currently compromised.” A functioning older router is not automatically an emergency. The appropriate response is measured: determine whether the model is still supported, install the latest official firmware if one exists, reduce avoidable exposure, and begin planning a move to supported hardware if updates have ended.
There is no universal expiry date
Age is a useful prompt to investigate, not a complete verdict. A router that is five years old is not necessarily obsolete for ordinary browsing or video streaming, and manufacturers do not all end support at the same time. Netgear suggests a four- to five-year timeline, but that is a checkpoint rather than an absolute deadline for every model.
The important detail is the exact router, not only the number of years it has been in the home. Two units marketed under the same model name can have different hardware revisions. A hardware revision is a particular version of the physical device, and it can use different firmware releases from another revision carrying the same broad product name. Checking only a familiar model label can therefore lead to the wrong download or an incorrect assumption about support.
If a router has been in service for several years, this is a good time to verify its status. If it remains actively supported and has the latest firmware installed, that is reassuring. If the official support information indicates end of life or end of support, the sensible position is to keep the network protected as well as possible while preparing a replacement.
How to check your router’s update status
Start with the label on the router. It is commonly on the underside or back and may show the model number, hardware revision, default Wi-Fi credentials and a login address. Record the model and revision exactly. The revision is not a decorative extra; it is necessary to match the device to the appropriate firmware and support information.
- Open the router’s management interface or companion app. Use the device’s documented login method, then look for the firmware update section.
- Check the installed version. Note what firmware version the router is currently running and whether the interface offers a newer release.
- Enable automatic updates if available. If the router offers automatic firmware updating, turning it on can avoid missing a future release while support continues.
- Visit the manufacturer’s official support page. Search using the full model and hardware revision, rather than the model family alone.
- Compare versions and read the release information. Check the latest listed firmware against the version on the router, and look for end-of-life or end-of-support notices.
If an official update is available, follow the manufacturer’s instructions and allow the process to complete. Do not improvise with a firmware file intended for a similar-looking model. Firmware is closely tied to the hardware revision, and using the wrong file or procedure can leave the router unusable.
Reduce exposure while you decide what to do
If support has ended, replacing the router sooner rather than later is the stronger long-term answer. In the meantime, there are still useful steps that do not depend on receiving a new firmware release.
First, make sure remote administration is disabled. Remote administration is the ability to reach the router’s management page from outside the home network. Turning it off removes one potential way for the management interface to be exposed beyond the home. It is not a universal cure for every security problem, but it is a practical setting to review on an aging device.
Second, use a strong, unique administrator password. The router’s administrator login controls its settings, so it should not rely on an easily guessed or reused password. This matters especially if replacement hardware is not arriving immediately and the existing router needs to remain in use for a while.
Third, install the final official firmware release if you have not already done so. An unsupported router cannot receive fixes that have not yet been written, but it should at least be running the most current vendor-provided version available for its exact revision. This is a baseline step, not a guarantee.
- Find and record the exact model number and hardware revision.
- Install the newest official firmware that matches that revision.
- Turn on automatic updates where the router supports them.
- Disable remote administration.
- Set a strong, unique router admin password.
- Check official support information for an end-of-life or end-of-support notice.
- Plan a replacement when official updates have ceased.
Custom firmware can be an option, with real trade-offs
Some older routers may have another route: custom firmware from a project such as OpenWrt. This is software developed outside the original manufacturer that may continue to support some hardware after official updates stop. It can be a technical alternative, but it is not a casual substitute for clicking an automatic update button.
Compatibility must be checked against the precise hardware revision. A router sold under one model name may have several versions, and support for one does not establish support for all of them. The installation instructions must also be followed exactly. Loading incompatible firmware or using the wrong process can turn working networking equipment into a paperweight.
For that reason, custom firmware is best understood as an option requiring careful verification, not as an obligation for every household with an old router. If the supported-device list does not clearly match the exact revision, do not assume it will work. Planning a replacement remains the simpler path when there is uncertainty.
Why replacement planning beats complacency
An old router that still handles a web page, a stream or an online match can create a false either-or choice: keep it forever, or replace it in a rush. There is a more practical middle ground. Confirm whether it is still receiving security maintenance. If it is, keep its firmware current. If it is not, apply the latest official release, tighten straightforward settings such as remote administration and the administrator password, then give yourself time to select replacement hardware.
This approach avoids two mistakes. The first is treating an end-of-support notice as evidence that a breach has already happened. The second is treating reliable day-to-day connectivity as evidence that long-term security support no longer matters. The device may still function perfectly while the window for vendor fixes has closed.
For anyone whose home network connects multiple personal devices, the useful question is not simply, “Does this router still work?” It is, “Can it still be maintained when a problem is found?” Once the answer becomes no, the router has earned a place on the replacement list—even if it is still doing its current job without complaint.
