Typical router warranties cover the unit for one, two or three years. Occasionally, a retail outlet may offer to extend the length of warranties when purchasing routers from their stores. A few vendors offer lifetime warranties on their routers. Naturally, longer warranties are generally preferable to shorter ones.
The warranty is intended to cover basic flaws in the router's manufacturing and hardware logic. They typically do not cover against the following:
- electric power surges in the home
- spilled liquid or other water damage
- installing third party firmware
