Is my router still getting security updates?
UK law makes every router maker publish a support period. Only two of the five checked publish it in a form you can look your own model up in. This checks yours against those two, and tells you plainly when nobody has published an answer.
Why most routers cannot be answered
Every maker here complies with the law. That turned out to be the least useful fact about them. A compliance statement can confirm that a support period exists without ever saying when yours ends, and three of the five stop exactly there. NETGEAR publishes its end-of-service list as a search box, so you can confirm a model you already suspect and cannot browse the rest. D-Link publishes the procedure by which it would notify you. BT promises a minimum period without naming it.
So the useful question is not whether a maker publishes, but whether what it publishes can be enumerated. Asus and TP-Link clear that bar and the rest do not, which is why a search here comes back empty more often than it comes back with a date. An empty result is a real finding about the state of the market, and dressing it up as “model not found” would hide the only thing this page discovered.
A printed date and a worked-out date are not the same thing
Asus prints an end date against each model. TP-Link prints an end-of-life date and, separately, a policy that adds three years to it. Both produce a date on this page and the second one carries an assumption the first does not, so every result says which kind it is and shows the date the maker actually published underneath.
The same care applies where a model name carries more than one date. TP-Link dates each hardware version separately, and Asus lists a handful of names twice without explaining why. In both cases the result shows the earliest date, because you might be the person on that one, and lists the others so you can check the label. If you want the same treatment for your phone or laptop, the phone update checker and the computer update checker work the same way.
Frequently asked
How long does a router get security updates?
There is no single answer, and the honest version is that most people cannot find out. UK law, the Product Security and Telecommunications Infrastructure regime, requires every manufacturer selling a connectable product in Britain to publish a defined security support period. Every major router maker complies. The catch is that complying does not mean publishing a list: a compliance statement can say the period exists without ever telling you when yours ends. Of the five makers checked for this tool, Asus and TP-Link publish something you can read model by model, and NETGEAR, D-Link and BT do not. Where a figure does exist it tends to be short by phone standards: Asus states four years on every current model, and TP-Link's policy is three years counted from the day it declares a product end-of-life.
Is my TP-Link router still getting security updates?
If it appears on TP-Link's end-of-life list, almost certainly not. TP-Link's PSTI page states that the support period ends three years after the product's end-of-life date, and links its end-of-life list. Nothing on that list is dated later than 2022, so adding three years puts every single entry in the past. If your model is not on the list, that is genuinely ambiguous rather than good news: the list itself was last updated in April 2024, so a router retired since then would be missing from it either way. Checking the firmware date in your router's admin page is a better signal about your own box than any list.
Does Asus still update my router?
Asus is the one maker here that prints an end date against each model. Its UK page lists roughly a hundred networking products with a date apiece, all of them four-year windows ending on 31 December. Two things are worth knowing about those dates. They are UK commitments made under PSTI, not global promises. And Asus adds that extended support may be provided after the stated date, so the date is a floor rather than a cliff: passing it does not prove updates have stopped, it proves Asus stopped promising them.
What about NETGEAR, D-Link or my ISP's router?
No date can be given, and it is worth being precise about why, because all three do comply with the law. NETGEAR ties support to End of Service and publishes its end-of-service list as a model-number search box rather than a browsable table, and the last-sale date its policy counts from is not published at all. D-Link publishes an end-of-life policy and a notification procedure without per-model dates. BT commits to a minimum period of product support service without stating the period. If you are renting a router from an ISP, which most British households effectively are, you never chose the hardware and there is no list to check it against. The practical route is to ask the provider directly, in writing, when the model you were sent stops receiving security updates.
What actually happens when a router stops getting updates?
Nothing visible. It keeps routing traffic exactly as it did the day before, which is why this deadline is so easy to ignore. What stops is the fixing of newly discovered flaws, and a router is a worse place for that than a laptop: it is the device every other device on your network trusts, it is reachable from the internet by design, and it is almost never looked at. Old routers are actively hunted for this reason. If yours is out of support, replacing it is a genuine cost, but it is a smaller one than most of the alternatives being sold around this problem.
Where do these dates come from?
Two manufacturer pages, read directly. Asus's UK networking-product support page, which prints an end date per model, and TP-Link's end-of-life list combined with the three-year window TP-Link states on its own PSTI page and links that list from. Nothing here is taken from a roundup or a review site. Where a date is arithmetic rather than printed, the tool says so on the result and shows the date the maker did publish, so you can check the working.
