Looking for some information regarding attended sysupgrade leading to a no internet issue. I was successfully able to upgrade two separate RP4s remotely from 24.10.0 to 24.10.1 and everything went as expected thanks God.
However when I did the same attended sysupgrade at home for my home router, WRT1900AC v1, I lost internet. The upgrade worked as I was able to get back into the router and see it was on 24.10.1. The WAN interface showed activity under Rx and TX but I hand no internet via WiFi or lan. While trying to troubleshoot, Windows said it was a DNS issue but I'm not sure. I was able to get the internet working again after reseting the router but of course lost all my settings and WG configurations.
Is the above issue a known problem for some routers? If not, is there anything that I can do to prevent this from happening again?
