    I put the IP address back to I think that is what it was.
    Apparently following the instructions here:
    "Set a static IP address in Windows for the LAN"
    was incorrect.

    I did re-read your post. I really don't understand DHCP server
    What are the correct steps to change the printer IP to

    Your first screenshot showed that there is a malware infection. You need to take care of that before anything else.

    I don't see the malware infection that you referred to. Can you be more specific?

    Yes, check for malware first. See your netstat screenshot where it talks of DNS changer and conficker.

    DHCP server info. See here:-

    To change the printer IP address you need to access its settings. See your printer manual for network settings. Printers usually default to getting their address via the DHCP server which does raise the issue of how the printer and Charlotte got the same address ( .5). Mmm.

    Perchance, is there any other network device like a modem, say? What you don't want is more that one DHCP server as address clashes will occur if you do.

    OK, let's stop going round in circles.
    1. Get the computer checked for malware. Malwarebytes from is a good start but bro67 has a link you could follow.

    2. Tell us what is on your network. Modem, router, wireless AP (access point) etc.

    From there we can make sure there is only one active DHCP server and move from that point.

    Thanks LinW,
    The mention of Confiker in Netstat comes from comments (echo) in the .bat file that I use to execute Netstat:
    "Echo 445 Conficker worm used this port in the past, normally used for shared
    Echo printers and file sharing.
    Echo Expected OK Connections
    Echo TCP ESTABLISHED 4 External Drive"

    I ran Malware bytes and found no threats.

    It is in the second post, second image. You are infected and that is why you are having problems. You need to clear all malware from all machines on your network first, before things will work. This is one thread on the malware that you have infected your computer with. How DNS Changer Trojans Direct Users to Threats - Threat Encyclopedia - Trend Micro USA

    This gives you more links, but Trend Micro's is going to be the same as all of the others. dns changer family of malware infection - Google Search

    In DHCP Connections-
    I got the printer ( changed to static, but when I tried to change the IP address it gave me:
    "Mac address already exists in wireless broadband routers data base"
    Does this mean that I must delete that entry and re-enter it with address
