LAN
Go through the following steps, in case no connection between the computer
and the devices can be established. Check after each step if the problem is
solved. If the problem cannot be located, call the Technical Support.
1. Check the status of the LAN connection in the Windows task bar:
Connected
Connection not established
If no connection was established, test the following:
Is the router switched on?
Is the patch cable connected correctly to the router and the computer?
2. Check the router settings:
Is the router set to DCHP server?
Is the IP address range sufficient for all the connected devices?
3. Check all connections:
Are the patch cable connected to the LAN ports and not the WAN port?
Are all cable connections between devices and router correct?
Are the cables plugged in tightly?
4. If the router is integrated into a company network, pull out the patch cable
from the WAN port.
Can the devices communicate with the computer, even though the
router is disconnected from the company network?
5. Turn off all devices, router, and computer. Firstly, turn on the router and sec-
ondly turn on the devices and the computer.
Has this been successful?
