Recommendation for End-of-Support/End-of-Life Products

From time to time, D-Link will decide that some of its products have reached End of Support ("EOS") / End of Life (“EOL”). D-Link may choose to EOS/EOL a product due to the evolution of technology, market demands,  innovations, and efficiencies based on new technologies, or the product matures over time. It should be replaced by functionally superior technology.


For US Consumer

If a product has reached End of Support ("EOS") / End of Life ("EOL"), there is usually no further extended support or development for it.


Typically for these products, D-Link will be unable to resolve device or firmware issues since all development and customer support have ceased. 


D-Link strongly recommends that this product be retired and cautions that further use may be risky to connected devices. If US consumers continue to use these devices against D-Link's recommendation, please ensure the device has the most recent firmware, frequently update the device's unique password to access its web configuration, and always have WIFI encryption enabled with a unique password.
