Check to see if there is any LED activity. Brother print servers have two LEDs on the back panel of the
machine. The upper orange LED shows Speed status. The lower green LED shows Link/Activity
(Received/Transmit) status.
„ The upper LED is orange: The Speed LED will be orange if the print server is connected to a
100BASE-TX Fast Ethernet network.
„ The upper LED is off: The Speed LED will be off if the print server is connected to a 10BASE-T
Ethernet network.
„ The lower LED is green: The Link/Activity LED will be green if the print server is connected to a
Ethernet network.
„ The lower LED is off: The Link/Activity LED will be off if the print server is not connected to the
network.

Note
Make sure that your machine setting for a wireless network is ON.
Check to see if the wireless signal on the LCD display is following in Ready mode or Sleep mode with
infrastructure mode: (Strong) / (Medium) / (Weak)
Your machine is connected to the wireless network.
If the signal is (None), your machine is not connected to the wireless network. To configure your
machine for a wireless network, see Configuring your machine for a wireless network (For MFC-8690DW
and MFC-8890DW) on page 21.
Note
If you attempt to connect to any network (ad-hoc or infrastructure mode) using open system authentication
the wireless signal strength indicator will show a full signal even if the machine cannot connect.

Print the Network Configuration List and check if the settings such as IP address settings are correct for
your network. The problem may be the result of a mismatched or duplicate IP address. Verify that the IP
address is correctly loaded into the print server, and make sure that no other nodes on the network have
this IP address. (For information on how to print the Network Configuration List, see Printing the Network
Configuration List on page 123.)
