If you changed the router’s LAN IP address, you need to change the PC’s address. If you turned on the router’s DHCP server, set the PC to obtain its address automatically. Otherwise, give the PC an address in the new subnet. You may need to restart the SonicWALL router to force it to assign an IP address to the PC.
Browse to the router’s new address and log in. The GUI displays the System > Status page.
