Can LAN address settings be changed for the LiftMaster MyQ Smart Garage Hub?
No. The LAN address (e.g., 192.168.0.2) of the Liftmaster MyQ Smart Garage Hub (821LM, 821LMB, 821LMC-SCM, MyQ-G0301, MyQ-G0401-ES) cannot be changed. The LAN address is assigned by the router (if DHCP is enabled) and does not need user involvement; however, typically resetting the hub causes the hub to request a new IP address from the router.
All LAN and internet connection settings of the universal hub are factory-set and cannot be changed. There is no need to change any of the universal hub's internal settings.
