I cannot complete the Wi-Fi settings network setup configuration.
Question Solution
Are you using security software? Confirm your settings in the installer dialog box.
Allow access when the security software alert message appears during the
printer installation.
Are your security settings
(SSID/Network Key) correct?
Reconfirm and choose the correct security settings.
The manufacturer’s name or model number of the WLAN access point/router
may be used as the default security settings.
See the instructions supplied with your WLAN access point/router for
information on how to find the security settings.
Ask the manufacturer of your WLAN access point/router or ask your Internet
provider or network administrator.
Is your Brother printer placed too
far from your mobile device?
Move your Brother printer within about 3.3 feet (1 meter) of the mobile device when
you configure the Wi-Fi network settings.
Are there any obstructions (walls
or furniture, for example)
between your printer and the
mobile device?
Move your Brother printer to an obstruction-free area.
Is there a wireless computer,
Bluetooth supported device,
microwave oven or digital
cordless phone near the Brother
printer or the WLAN access
point/router?
Move other devices away from the Brother printer.
Are you using MAC Address
filtering?
You can confirm the MAC address by printing out the printer set-up information.
Press and hold the (Feed) button on your printer to print the printer set-up
information.
When you use RJ-3150/3150Ai, you can confirm the MAC address on the LCD
display of your printer.
1 Press the [Menu], [ ], or [ ] button to select the [WLAN] menu, and then press
the [OK] button.
2 Select [WLAN Status] using [ ] or [ ], and then press the [OK] button.
Is your WLAN access
point/router in stealth mode (not
broadcasting the SSID?)
You should enter the correct SSID name during the installation or when using
[Communication settings] in the Printer Setting Tool.
Check the SSID name in the instructions supplied with your WLAN access
point/router and reconfigure the wireless network setup.
