Change devices network after reset

Hi,

I have a bunch of Shelly 2.5 (and one 1pm) and they’re all configured to use static ip.

Recently, I’ve factory reset my router and now all of the devices are seemed to be offline (except for one 1.5pm, one Shelly button, one motion sensor and one humidity and temperature sensor).

What can I do to reconnect those devices? Does setting static ip has anything to do with it?

Thanks!

I did just that, but only few devices went back on…

same data I mean same network name (SSID) with same use and pass
