Hello! Thank you for contacting JustAnswer.com; I am Russell H., an Expert here at JustAnswer.com, and I will do what I can to answer your question as well as it can be answered.
The wrong password ***** message may be owing to the passphrase for the WiFi being entered wrongly.
It must be entered so that UPPER CASE letters are entered differently from lower-case letters, for instance. That is quite absolutely necessary.
If you aren't sure the LETTERS/letters portion of the passphrase have been entered correctly, then please tell me what printer - by maker and model # - you have, and I will tell you how to enter the passphrase (whatever it is, and with examples provided) so that it will work.
