If you like you can go for changing the guest network reserved address range using telnet commands as follows:

nvram set lan1_ipaddr=192.168.3.1
nvram set lan1_gateway=192.168.3.1
nvram set lan_ipaddr2=192.168.3.1
nvram set dhcp_start2=192.168.3.2
nvram set dhcp_end2=192.168.3.254
nvram commit
reboot the router
Set the LAN IP address to 192.168.2.1 in the Orbi web GUI under >> ADVANCED >> Setup >> LAN Setup
