Modem Gateway: how long support actually lasted
Ranked by the firmware history we hold, longest first. Every span is measured between the first and last firmware we saw, so each is a lower bound — no vendor here publishes a launch date, and support that began before the first release we know of is support we cannot count.
Only products whose support has demonstrably ended appear. A device still receiving firmware has a span that is still growing, and ranking it against finished ones would put the best-supported hardware at the bottom for still being supported.

What this ranking leaves out
Of 25 products in this category, 13 could be ranked.
- 2 still supported — their span has not finished, so ranking them would understate them.
- 10 carry no verdict — we looked and declined to judge. Their device pages say why.
