The DIR-850L hardware revisions are legacy devices listed in the table below. All hardware revisions reached their end-of-life ("EOL") Life Cycle on March 1, 2020. D-Link US recommends that D-Link devices that have reached EOL/EOS be retired and replaced. Please get in touch with your regional office for recommendations (LINK).

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 EOS/EOL a product due to technological evolution, market demands, new innovations, product efficiencies based on new technologies, or the product maturing over time and 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 has 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 updates its unique password to access its web configuration, and always has WIFI encryption enabled with a unique password.
