 If  you  change  the  IP  address  and  click  Save  Settings,  the  GUI  will  not  respond. 
Open  a  new connection  to the new  IP  address  and log in again. Be  sure the  LAN 
host (the machine used to  manage  the  router)  has  obtained IP address from newly 
assigned  pool  (or  has  a  static  IP  address  in  the  router‘s  LAN  subnet)  before 
accessing the router via changed IP address.
