Sometimes—but the TP-Link name alone cannot answer the question. Safety depends on your exact model, hardware revision, sales region or ISP deployment, installed firmware, and whether TP-Link still provides security updates for that variant. Check those details against the current regional support information. Install the matching official firmware when one exists. If an affected router is end of life and remains unpatched, replace it with a supported model that receives ongoing security updates.
Why there is no brand-wide yes or no
A TP-Link router is not automatically unsafe because it carries that brand. The same product family can include several hardware revisions sold in different regions, with different firmware and different support dates. A security advisory may apply to one revision but not another, or list one revision as patched while another remains unpatched.
Your decision should therefore be made at the variant level. Record the model name, hardware version, region, firmware build, and—if the router came from an internet provider—the provider and deployment type. Compare those details with the current TP-Link support page and security advisories for your region. Do not rely on a search result that mentions only the family name, such as “Archer” or “TL-WR.”
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsThe practical rule is straightforward:
- Supported and current: keep using the router, while applying future official updates.
- Affected but patchable: install the firmware for the exact revision and region, then verify that the new build is active.
- End of life and unpatched: plan replacement. Security settings can reduce exposure, but they cannot repair a flaw for which no patch exists.
What TP-Link’s advisories show about older routers
TP-Link’s advisory for CVE-2023-50224, updated May 12, 2026, describes an improper-authentication flaw in the httpd service. According to the advisory, a network-adjacent attacker may retrieve sensitive information, potentially including stored credentials. The advisory also refers to public reporting of exploitation activity involving legacy consumer networking equipment and campaigns that included DNS manipulation. That does not establish that every owner is compromised; it does establish why an affected, unsupported router should not be left exposed indefinitely.
#1 Best Overall
The manufacturer rates CVE-2023-50224 at CVSS v3.0 6.5, Medium. A CVSS score describes the characteristics and severity of the vulnerability, not the percentage of routers that are compromised and not your personal probability of attack.
The advisory’s table illustrates why the hardware revision matters:
| Model and revision | Status listed by TP-Link for CVE-2023-50224 | How to interpret it |
|---|---|---|
| Archer C5 V2 | Patched | An official fix is listed for this revision; install the matching regional firmware. |
| Archer C7 V2/V3 | Patched | Do not assume other Archer C7 revisions have the same status. |
| TL-MR6400 V1/V2 | Unpatched | If your exact unit is still affected and end of life, replacement is the durable remedy. |
| TL-WR841N V8–V12 | Partially patched | Read the revision-specific notes; “partially patched” is not equivalent to fully remediated. |
| TL-WR940N V2–V6 | Partially patched | Confirm precisely what the listed firmware fixes and whether your regional build is covered. |
Many other older variants in the same advisory are marked unpatched. TP-Link also notes that not every listed model was sold in every region and that regional firmware differs. A status shown for one revision or country cannot safely be generalized to another.

Use this sequence before deciding to keep or replace the device. The labels in the administration interface vary by model and firmware, so use the wording on your screen rather than assuming a universal menu name.
Rank #2
- Read the product label. Write down the complete model number and hardware version, often shown as “Ver,” “V,” or “H/W Ver.” Include the revision printed on the underside or rear label, not just the name on the box.
- Identify the firmware build. Sign in to the router’s local administration interface or its supported management app and open the status, system, or firmware-information page. Record the full version string and date if displayed.
- Establish the correct region. Use the country or regional TP-Link support site where the router was sold. Hardware sold in one market may have different firmware from an apparently identical unit sold elsewhere.
- Search the exact variant. Open the support and security-advisory entry for the model and hardware revision. Read the affected-version, fixed-version, and end-of-life notes; do not stop at the product-family landing page.
- Check the update method. Download only the firmware identified for your exact revision and region. Follow the model-specific installation instructions, including any requirement to unpack a file or connect by Ethernet during a manual update.
- Verify after updating. Reopen the information page, confirm the installed build matches the fixed version, and review security settings because an upgrade may reset or alter configuration options.
TP-Link says that the legacy models listed in its CVE-2023-50224 advisory do not support cloud-based or automatic firmware updates. For those devices, waiting for an in-app notification will not work; a manual, model-specific update is required when a fix is available. Never flash firmware intended for a different hardware revision or region. A seemingly successful installation can leave the router unstable, unsupported, or still vulnerable.
What “end of life” means for security
TP-Link defines end-of-service products as no longer receiving active support, including security updates. Once a device reaches that point, newly discovered weaknesses may remain open even if the router continues to provide Wi-Fi and internet access normally.
TP-Link states: “Utilizing end-of-life networking equipment carries a real risk because vulnerabilities that emerge after support ends cannot always be patched.” This is the manufacturer’s guidance for Spectrum customers, not an independent measurement of every installation, but it captures the operational problem: working hardware is not the same thing as maintained hardware.
Recommended Free Tools
End-of-life status does not by itself prove that a router is currently compromised. It means you should not expect a dependable response to the next vulnerability. If an end-of-life unit is not listed as affected by a known advisory and your exposure is low, you may choose to keep it temporarily while budgeting for replacement. If it is affected and unpatched, replacement should move from optional maintenance to a priority.
TP-Link’s compliance statement says that, for products covered by that statement, its defined support period ends three years after the product’s end-of-life date. That is not a universal promise for every TP-Link product or market. Confirm the exact model, region, and published lifecycle before treating the three-year period as applicable to your router.
A newer hardcoded-credential advisory reinforces the need for exact-model checks
TP-Link’s advisory for CVE-2026-12001, updated August 11, 2026, concerns hardcoded credentials and lists fixed firmware versions for several specific variants:
| Model and revision named in the advisory | Advisory detail |
|---|---|
| TL-WR845N V4 | Fixed firmware version listed by TP-Link. |
| TL-WR850N V3 | Fixed firmware version listed by TP-Link. |
| TL-WR902AC V4 | Fixed firmware version listed by TP-Link. |
| Archer C20 V6 | Fixed firmware version listed by TP-Link. |
| Archer MR200 V5 | Fixed firmware version listed by TP-Link. |
The advisory assigns CVSS v4.0 5.2, Medium, and notes that some listed models are not sold in the United States. Because the fixed build numbers and regional availability are model-specific, use the advisory’s current entry rather than copying a version from another country or revision.
When to keep the router, update it, or replace it
Keep it when support is active and the firmware is current
If the exact model and revision remain within the manufacturer’s support lifecycle, no applicable advisory requires a missing fix, and the installed firmware is current for your region, the available evidence does not justify replacing the device merely because it is made by TP-Link. Keep automatic update checks enabled when the model supports them, and periodically review the regional support page for new advisories.
Rank #4
Update it when a matching fix exists
Download the official build for the exact hardware revision and region, follow the model’s instructions, and verify the version afterward. If the advisory describes a partial fix, read its remaining conditions before treating the router as fully remediated. A patched build for a different revision is not a valid substitute.
Replace it when it is affected, unsupported, and unpatched
TP-Link advises moving affected legacy devices to a supported product that receives regular security updates. Replacement is especially important when the router is exposed to the internet through remote administration, serves many devices, handles sensitive work, or is installed in a small business or shared environment. Do not interpret this as a direction to replace every TP-Link router; make the decision from the exact variant’s status.

These controls reduce exposure; they are not a substitute for a missing security patch.

- Turn off remote administration. Disable management from the internet unless you have a documented, necessary use and a tightly controlled access path.
- Disable services you do not use. Review features such as remote file sharing, vendor cloud management, exposed administration ports, and other optional services. Keep only what your household or organization needs.
- Restrict administrative access. Use a strong, unique administrator password and limit management to a trusted internal network. Do not reuse an email, banking, or workplace password.
- Segment untrusted devices. Put guest devices and equipment that does not need access to computers or network storage on a guest or isolated network when the router supports that function.
- Watch DNS and configuration changes. Unexpected DNS servers, unfamiliar administrator accounts, changed Wi-Fi names, or altered port-forwarding rules deserve immediate investigation. Restore known-good settings and contact your ISP if you cannot explain a change.
- Plan a replacement date. Temporary mitigations are easy to leave in place indefinitely. Set a budget and deadline for a supported router.
Special case: ISP-managed Aginet equipment
Aginet products supplied and managed by an internet provider follow a different update path. TP-Link’s advisory updated October 9, 2026 describes multiple vulnerabilities requiring network access, with some issues also requiring valid device-management credentials. Applicability varies by ISP deployment, and the affected provider-specific firmware may not be publicly downloadable.
Check the device-management interface or the ISP’s supported app for update status. If the interface does not show a version or update option, ask the ISP whether your deployed variant is affected, whether an update is automatic, and when it was or will be installed. Do not replace or manually reflash an ISP-managed unit without confirming that the provider supports the change; doing so can interrupt service or remove the provider’s management configuration.
How to choose a replacement router
When replacement is warranted, compare support practices before comparing speed claims. The sources do not establish one universally best model, so evaluate the candidate against your connection and household:
| Question | What to verify | Why it matters |
|---|---|---|
| How long will it be maintained? | A published security-update policy, support period, and end-of-life process for the exact model. | Hardware that is fast today can become a liability when updates stop. |
| Will it work with the connection? | Compatibility with your ISP, modem or fiber terminal, authentication method, and required telephone or television services. | A secure router that cannot authenticate or deliver required services is not a practical replacement. |
| Can it cover the home? | Wireless coverage, building layout, number of clients, and whether wired backhaul or a mesh arrangement is needed. | Capacity and placement affect reliability as much as the headline Wi-Fi generation. |
| How are updates delivered? | Whether updates can be applied reliably, whether the model remains within its lifecycle, and what happens after support ends. | A clear update path makes future vulnerability response less dependent on manual work. |
Keep the old router disconnected or reset it before disposal. If it handled administrator passwords, Wi-Fi credentials, or ISP login details, change those credentials on the replacement and follow local electronic-waste guidance for the retired device.

Common mistakes that leave an updated-looking router exposed
- Checking only the family name: “Archer C7” or “TL-WR841N” is incomplete without the hardware revision.
- Using a neighboring region’s firmware: Regional builds can differ even when the casing and model label look identical.
- Assuming an automatic update exists: The legacy models in the CVE-2023-50224 advisory require manual updating.
- Treating “partially patched” as “fixed”: Read the advisory notes and remaining conditions for that revision.
- Confusing a vulnerability score with compromise evidence: CVSS 6.5 or 5.2 is a severity rating, not an infection rate.
- Leaving remote management enabled during a replacement delay: Internet-facing administration increases the opportunity to attack an old device.
Bottom line
It can be safe to keep using a TP-Link router, but only after you identify the exact hardware revision, region, firmware, and support status. Apply the official, matching update when one is available. Treat an affected end-of-life model that remains unpatched as a replacement priority; disable remote management and unnecessary services while you transition, because those measures reduce risk without fixing the underlying flaw.
