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. ...
Personally I'd get standalone AP's and hang them off a standalone switch so that if the internet gateway goes down the LAN experience is not interrupted.
I don't know what that would do for me, though, what can I do on the LAN when the internet gateway is down? Also, why should the gateway reboot? I would like it to be up all the time
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.
