help OpenWrt Build for Atheros AR7171 FAQ
Is the OpenWrt AR7171 build a universal router image?
No, it is intended for older Atheros AR7171 hardware and must match the exact board layout and flash size. A firmware image for one router can fail or brick another router even when both use Atheros chips.
Is the old ar71xx OpenWrt target still current?
No, OpenWrt marked ar71xx as deprecated and moved supported hardware to the ath79 target. The ar71xx target was removed in OpenWrt 21.02, so use an ath79 build when one exists for the device. [OpenWrt](https://openwrt.org/docs/techref/targets/ar71xx)
Can I flash this AR7171 build onto any Atheros router?
No, check the exact model in the OpenWrt hardware table and confirm whether the image is a factory or sysupgrade image. OpenWrt's installation guidance also recommends backing up the configuration and using the image made for that device. [OpenWrt installation guide](https://openwrt.org/docs/guide-user/installation/ar71xx.to.ath79)
What is a stripped-down OpenWrt build for AR7171 hardware good for?
It is best suited to simple routing, firewalling, or other lightweight network roles where the old processor and memory are enough. OpenWrt specifically warns that devices with 4 MB of flash or 32 MB of RAM have very little room for packages and modern services. [OpenWrt](https://openwrt.org/docs/techref/targets/ar71xx)
