I'm about ready to give up again.
Make sure that the computer you are using to print is connected with a network cable. If you have a wireless connection it should be disabled.

For Windows this one works well:

If it works fine with a wired configuration but the problem is with a wireless configuration then most likely you will need to hire someone to help configure your network. New equipment may be needed.
