Cause The HP All-in-One is assigned an AutoIP address instead of DHCP.
Solution This indicates that the HP All-in-One is not connected properly to the network.
Check the following:
● Make sure all cables are connected properly and securely.
● If the cables are connected properly, your access point, router, or home gateway might
not be sending an address. If this is the case, you might need to reset the device.
● Make sure the HP All-in-One is on the correct network.
Cause The HP All-in-One is on the wrong subnet or gateway.

on the same subnet and gateway.

I am using a cable modem without a router and I do not have IP addresses
Cause If you have a computer with a cable modem, a separate Local Area Network (LAN)
for your other computers, and no DHCP or router, you must use AutoIP to assign IP addresses
to the other computers and to the HP All-in-One.
Solution
To obtain an IP address for the computer with the cable modem
➔
Your Internet Service Provider (ISP) assigns either a static or dynamic IP address to the
computer with the cable modem.
To assign IP addresses to the remaining computers and the HP All-in-One
➔
Use AutoIP to assign IP addresses to the remaining computers and the HP All-in-One.
Do not assign a static IP address.
