MikroTik

I unbox my new hAP lite and I upload configuration.rsc file. I start command in terminal window /system reset no-defaults=yes run-after-reset=configuration.rsc. Router reboot and after that access is not possible any more (Winbox does not see router MAC or IP address). If I tray to reset .... nothing happened.....

I try same procedure on next router and I find, if I made firmware upgrade first everything works fine. Router is reachable after I run script . Unfortunately before I find solution I destroy 3 routers. Can I fix them somehow ?

I made a lot of research but can not find proper solution....

Any advice ?

.......nobody ????? Procedure how to load default setings ???

please reinstall the hAP lite with the new RouterOS using Netinstall.
Press and hold the reset button and power on the board, keep holding the reset button for approx 10-15 seconds till it goes into the network boot.
Then use Netinstall tool to reinstall it.
