I had a major hack a few weeks ago. My Hp Envy 7155 got disconnected, and I have not been able to get it back up. I wish I could talk to a real person, but that seems impossible anymore.  I am very frustrated.  My blue wifi light is blinking, and when I check, all it does is tell me I am disconnected from my wifi!  I KNOW THIS ALREADY!  This printer was terrific till I had this hack.  Now NOTHING is making is work. Please—somebody—help me fix this.

I am replying to my own post.  I see that 25 views of my post have happened, but no replies.  But I did not wait.  I might not hear from anyone in the community for days, so I kept at it.  I was becoming very frustrated, but I stayed with it, and I finally figured out how to fix the problem.  When I was hacked, I had to change everything, including my wifi password.  I was sure the solution to my printer problem was related to the password change, but I could not find the place to change it.  (The "non-manual" is really difficult to navigate).   I kept pushing buttons, however, and I finally stumbled on it.  I changed the password, and I can now print.  The quality of the photo, which was the first thing I printed, was terrible, but that's another issue.  I am glad just to have the thing working again.
