I have flashed current snapshot to an ER-X, initially keeping settings, but also last tried not keeping settings. I manually edited the network file with vi to modify the lan configuration for my network:
a) change static IP to my network subnet 10.xx.xx.xx
b) option gateway '10.xx.xx.yy'
c) list dns '1.1.1.1'
When I reboot or power off-on, the changes I have written to the /etc/config/network config file with vi are gone, and the network file has been replaced with the default configuration again. Luci has not been installed yet, so it can't be the Luci auto-rollback after a time delay with no reconnect, can it?
I've done this many, many times in the past on different devices - including this ER-X. I've never had this happen to me before. And its only this one ER-X device. I repeated the process on a different device (same snapshot version), and everything worked as expected, just like in the past: I can reach the device on my lan plugged into the port of one my routers configured as AP/switch, I have internet connectivity through my gateway router, I do an opkg update, I install luci and other packages I use. Simple. If I reboot, everything is as I left it.
Not now. Not with this one ER-X device. I'm beyond exasperated - it keeps rolling itself back to defaults. Which means I have got to be doing something really stupid. That, or there is an evil gremlin inside the router.
Has this happened to anyone before, and if so, can you offer any hints on the stupid thing I'm doing? I promise not to tell anyone you did it too
