Affected Models Summary

Recommendations for End of Support and End of Life Products

D-Link periodically designates products as EOS or EOL due to technology changes, market demand, or lifecycle maturity. Products in this status should be replaced with newer models offering improved functionality and active support.

Guidance for US and Canada Consumers

• Products that have reached EOS or EOL no longer receive technical support, firmware updates, or security remediation.
• Continued use of EOL and EOS products increases security risk to connected networks and devices.
• D-Link strongly advises discontinuing use of these products.

Security Reports for EOL and EOS Devices

• D-Link does not accept or validate vulnerability reports for EOL or EOS products.
• No firmware updates or hotfixes will be released.
•  The last available firmware appears on the legacy site for reference only:
  https://legacy.us.dlink.com/
• Continued use of EOL or EOS devices occurs at the user’s own risk.
