connecting to different wifi module

Hello there. Bit of a strange one, i would like to reconnect a Hybrid gen 3 inverter to a different wifi router, its not a replacement wifi router but essentially a second router id like to connect to and for it to forget about the first router i am currently connected to.
is it just a case of reconnecting the built in wifi dongle following the instructions on the wifi guide? or does it need resetting first some how? just dont want to confuse the system if it tries to connect to 2 wifi routers.
thanks inn advance?

robstorr is there a reason the 2nd router can't have the same SSID and password, almost acting like a mesh network?

Otherwise yes, the instructions should do the trick, just remember it'll be 2.4Ghz band only and it'll only try to connect to that one in future

Alternatively, don't the G3 have LAN capabilities? Is that an option?
