ive a brother j315w which im trying to connect to wifi every time i enter the password it says its wrong. can anyone help ?

Are any of the characters upper case rather than lower case? To a computer  ABC is different to abc, or Abc or aBc, etc etc.

it now works. i entered the tcp/ip values then ran the setup wizard and suddenly connected.

1. Before you set up your Brother machine

You must find out the wireless network settings of your wireless router or access point. Check and write down the current wireless network settings below (you will need this information later):

Network Name (also known as "SSID" or "ESSID")

Network Key (also known as "Password", "Security Key", or "Encryption Key")

Download the manual listed below (if you don't already have a copy of the "Network User's Guide") and go to page 27 -- Configuring your machine for a wireless network.

Sure. Your password is probably "123". Hope this helped.

That's because you entered an incorrect password.
