Cambium Networks N500 End-of-Life & EOSL Dates

PAST VENDOR SUPPORTCambium Networks ended support in September 2025.

Cambium Networks N500 — end-of-sale and end-of-support dates by part number, as published by Cambium on its Product Life Cycle page.

Every tracked Cambium Networks N500 SKU group is past Cambium Networks end of service life (last group Sep 2025). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure. Cambium Networks’ named migration path: N550.
