Connect Brother Printer to Wifi Without Password

Brother MFC-L2700DW Wifi Setup

You must check the network settings of your wireless router. You need to write down the Network name and network key of the router.
For SSID and password, you can check the base or side of the router.
After checking your network setting requirements, you can proceed to the setup of the printer.
Once you have located the network settings, press the Menu button on the printer, select Network, and press OK.
Then, select the Setup Wizard and press OK.
After that, press the UP arrow and select your network.
Further, enter the network key or password of the router.
Finally, it is connected and you can try printing.

Suppose you have a wireless router/access point supporting the WPS (Wi-Fi Protected Setup) or AOSS (AirStation Secure System). In that case, you can easily connect your wireless network/access point with your brother printer just follow the given step without skipping any step:

CONFIGURE THE WIRELESS SETTING

Bring the Wi-Fi router and your Brother Printer as near as possible.
Ensure that the power cord is plugged in.
Then, turn the printer ON and wait until the printer is in the READY state.
After that, a few seconds hold down the WPS button on your wireless network/access point.
As shown in the given photo, for less than 2 seconds, click the wireless setup located on the back of the router.

NOTE: To click the wireless setup button, use a ballpoint pen or a sharp point object. Do not press the button for more than 2 seconds.

The machine will then start searching for a wireless network that supports the WPS or AOSS for 2-3 minutes. At that time, the TONER LED will start blinking.
After that, the printer tries to connect a wireless network/router. At that time, both the TONER and DRUM LED will start blinking.
Now, wait until the printer indicates the READY LED will start blinking. This button will turn ON for 5 minutes. This suggests that the printer is connected with the wireless network router/access point.
