Overview
The DIR-632, all hardware revisions, and firmware versions are legacy devices, and the affected are listed below with details in the table. All Models and all hardware revisions have reached their end-of-life ("EOL") /End-of-Service Life ("EOS") Life Cycle. D-Link North America recommends that D-Link devices that have reached their end of life (EOL) or end of service (EOS) be retired and replaced. If you are outside North America, please contact your regional office for recommendations (LINK).
As a general policy, when products reach the end of support (EOS) or end of life (EOL), they can no longer be supported, and all firmware development for these products ceases. Please read the information and recommendations below.

Recommendation for End-of-Support/End-of-Life Products
From time to time, D-Link will decide that some of its products have reached the End of Support ("EOS") / End of Life (“EOL”). D-Link may choose to end-of-sale (EOS) or end-of-life (EOL) a product due to technological evolution, market demands, innovations, or product efficiencies based on the latest technologies, or when the product matures over time and should be replaced by functionally superior technology.
For US Consumers
If a product has reached the End of Support ("EOS") / End of Life ("EOL"), it usually does not receive further extended support or development.
Typically, D-Link cannot resolve device or firmware issues for these products since all development and customer support have ceased.
D-Link strongly advises against using end-of-support products, as their continued use may pose significant risks to the devices connected to them. Suppose US consumers choose to disregard this advice. In that case, it is crucial to ensure the device has the most recent firmware, frequently update its unique password for web-configuration access, and continuously enable WIFI encryption with a unique password.
Regarding the Security Update for Your D-Link Device
Installing firmware updates is critical in addressing security vulnerabilities in your D-Link devices. D-Link strongly recommends that all users install the relevant updates and regularly check for further updates. After downloading the firmware update, it is essential to ALWAYS validate its success by comparing the firmware version on your product interface to the firmware update version.
Please note that beta software, beta firmware, or a hot-fix release is still undergoing rigorous testing before its official release. This ensures that the software is of the highest quality and meets our stringent standards. However, it is essential to understand that the user assumes all risk and liability for its use. D-Link does not provide express or implied warranties regarding the suitability or usability of the beta software, beta firmware, or hot-fix release. D-Link will not be liable for any direct, indirect, special, or consequential loss suffered by any party due to their use of the beta firmware, beta software, or hit-fix release..
NOTE: Our products have different hardware revisions, so please check your device’s hardware revision before downloading the corresponding firmware update. The hardware revision can be found on the product label next to the serial number or on the device's web interface.
