Today, we at SFC, along with our OpenWrt member project, announce the production release of the OpenWrt One. This is the first wireless Internet router designed and built with your software freedom and right to repair in mind. The OpenWrt One will never be locked down and is forever unbrickable. This device services your needs as its owner and user. Everyone deserves control of their computing. The OpenWrt One takes a great first step toward bringing software rights to your home: you can control your own network with the software of your choice, and ensure your right to change, modify, and repair it as you like.
The gateway device should definitely be up at all times, but in the real world, things don’t always go as planned.
If you only use the internet, then maybe having your AP go down when your gateway goes down is fine. For us avid self-hosters, that is unacceptable behavior.
