Interesting, though I question why a battery backed RTC is seen as so critically important. Of all the features I can think of wanting in a router, a battery backed RTC doesn't even begin to make the cut. A device that is powered up 24/7 and connected to the Internet can just get NTP time whenever it boots up and keep time using the OS. What is so necessary about an RTC here? I get that time is used for certificate verification and other security stuff, but again NTP and always powered. Are they concerned that NTP could be an attack vector?
I'm interested in a new OpenWRT router as my WRT1900ACS is getting older and the WiFi driver on it never had amazing support. Right now the Banana Pi R4 looks promising as a WiFi 7 OpenWRT supported router as it looks like most off the shelf WiFi 7 routers do not have OpenWRT support.
A battery back RTC could make it faster and more reliable reconnect after power loss?
Battery back up surge protectors are pretty affordable these days. I’ve had an APC going for 5 years so far, battery tested fine recently, cost me like $150. Anyone who is doing a lot of home networking/tech stuff should be using them anyway.
