If the message continues to be displayed, proceed as follows:
¥ Check whether your phone's Ethernet cable is correctly connected to the router.
¥ Check your router's cable connection to the Internet.
¥ Check whether the phone is connected to the LAN. Send a ping command, e.g. from your

could be assigned to the phone or a permanently set IP address is already assigned to
another LAN subscriber. Check the settings on the router, you may have to activate the
DHCP server.
