Whenever it says "Enter" read this as "OK"
Why the printer doesn't just say "press OK" I couldn't tell you.

Enter & ok key


You must have forgotten something that came after Enter (....) and OK. I checked the whole manual and could not find such a string.
Please refer to the manual.

Brother mfc-7840W not picking up wireless IP address


It is common, mainly because the MFC connection is lost to your PC. Are you able to print or scan from another wireless PC that you have? If yes, contact your network admin or router oem. If no, reset network card. Run the Setup Wireless Wizard. Make sure you have router info such as SSID, Network Security Key, Authentication Method (Open, Shared, WPA/WPA2-PSK), Encryption (None, WEP, AES, TKIP). Enter those info, it must be CASE SENSITIVE. Just in case you dont know your router info, contact your router oem.
For Advanced Users.1. Click your Wireless Icon at Task Tray2. Right-Click your Wireless Network Name3. Select Properties4. Go to Wireless Security Settings5. Take note of the settings that you have there and enter it again on your MFC
Goodluck! If you still need more assistance. Call us 1-877-Brother. :)

Hi,

The solution I'm suggesting works in my business (LAN installations) about 95% of the time. I trust that it will work for you.

Let's see if I can help you.

Begin by turning on your computer and your router

Make certain that you have the latest drivers from Brother by clicking on the following link: Brother Driver Downloads

Open Control Panel and click on 'Diagnose Connection Problems' and follow the instructions.

The last choice is to use the Setup Wizard. It seldom works for me but you might more luck than poor me. Here are the instructions:

The Connect to the Internet wizard will guide you through the steps of setting up an Internet connection.

Open the Connect to the Internet wizard by:

• Clicking the Start button Picture of the Start button
• Click on Control Panel.
• In the search box, type network,
• Click "Network and Sharing Center"
• Click Set up a new connection or network
• Then double-click "Connect to the Internet".

This should have you up and running.

All the best

Brother's documentation is non-intuitive. Pressing the ' 0 ' key shows a ' * ', but it actually is accepted as a 0 and moves to the next character entry position. Just take it on faith that it enters a 0 when it shows * when entering the wireless key.

To setup your Brother MFC-7840W on a wireless network do the following:

Press Menu.

Scroll down to #5 LAN and hit OK

In the LAN submenu, scroll down to 2. WLAN and hit OK.

In the WLAN submenu select 2. Setup Wizard.
(The printer will search for the SSID of your network. If you are presented with multiple networks, select yours and hit OK.)

Depending whether you have setup a network key on your wireless network, you will have to choose the type of connection. Your options will be Open System, Shared key, and WPA/WPA2-PSK.

If you have a Shared Key or WPA/WPA2-PSK network, then you willhave to enter the key to connect. Open Key does not use a key to connect.

So for instance, if you selected WPA2-PSK you will then be asked to enter your passphrase key to connect to your wireless network.

Brother MFC-7840W Printerwill only give me Scan To FTP option now


i had the same issue - was previously able to scan to a number of different formats, then switched modems, providers and then only the scan to ftp option came up.
took me about an hour to figure out the solution, but now it works
for windows users: * go to your control panel * go to the scanners & cameras section * your printer/scanner should show up here * right click on it and select 'properties' * select the network settings tab and then -- enter in the correct ip address here OR -- specify your machine by name (enter in name here)
hope this helps!
