Why a fork exists
A fork can adapt a project to additional hardware or maintain support paths that differ from the original project. That does not make every ASUS router compatible.
Check the exact model
Model support should be confirmed against the fork’s own build list and release notes. Similar names or shared product families are not enough.
Treat updates independently
A release from one branch should not be treated as interchangeable with another branch. Keep track of which firmware family is currently installed before changing versions.
Use the same safety discipline
Back up settings, use stable power, prefer a wired connection and understand the router recovery method before flashing any third-party firmware.
Practical takeaway
Keep changes model-specific, document your current settings, and test one change at a time. That approach makes future upgrades and troubleshooting much easier.
