Do you use an USB cable or wireless connection to connect the printer ?
Does the printer suddenly stopped working or do you have changed anything, before the problem started ?
Do you have tried anything to solve the problem, so that I can skip those steps .
Is it a new printer ?
What password ***** are entering in the computer ?
OK, so mean to say that, your computer is unable to connect with the wireless network, right ?
Ok, then that should be your question and not the one, you posted. Can you tell me, what message do you get, when you enter the WEP key ?
