Overview

Editorial opinion

The WR3000 brings the popular Filogic 820 platform and open-source Wi-Fi drivers to a very low price, which made it a common budget pick on the OpenWrt forum.

Two things to watch: only 16 MB of flash, which limits extra packages, and a confusing range of versions, some of which have shipped with flash chips not yet supported by OpenWrt.

Hardware revision warning. Only the WR3000 v1 is covered by this OpenWrt image. Cudy sells several similar models (WR3000 v2, WR3000E, WR3000S, WR3000H, WR3000P); Amazon.com currently lists the WR3000 V2.0, which is different hardware. Newer units may also use a flash chip that OpenWrt does not support yet. Check the exact model and version on the label before buying.
