|the port I connect to has the amber light come on|
I would expect that. An HP LaserJet 4000 series will have a 100 Mbps network interface and that orange light on your router should be indicating a 100 Mbps connection.
I have reset to factory setting thinking it would reset and capture a new ip address.
You have to either enter the TCP/IP settings manually on your printer (recommended) or you will have to set it to DHCP. The network interface will not be set to DHCP by default, or be preconfigured with an IP address.
A typical SOHO Router will have a DHCP scope similar to the following:
192.168.0.100 to 192.168.0.199
I would use an IP not in the scope to configure the printer with. I'm using 192.168.0.10 on my 4000 series HP LaserJet at home. Using an IP outside the scope avoids possible duplicate IP issues.
One should always use static IP addresses for things like network printers or servers. If you used DHCP, it's possible the IP could change and then you'd have to reinstall the printer on all client PC's in your LAN.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
