Network won't accept DHCP IP.

[MacWilder]

My printer formerly was on a network with IP's 192.168.1.x.  Now it's on a network with 10.0.0.x IP's.  However, when I try to set it up, while the setup facility does see the new network, I nevertheless I get a message saying that my new 10.0.0.x network is incompatible with the old 192.168.1.x network.  I have only one network in my facility.  There are no other wireless networks within range.  The 10.0.0.x network is the only network in my facility.  The SSID is new and unique.  Therefore, in the context, the message is clearly fallacious.

(Others in this forum have had the same problem, but, as far as I can determine, none got an answer that resolved the issue.)

Temporarily, I am using the printer via a USB connection, but I need to get it working wirelessly.

Thank you for any help.

Hi,

You need to use the printer's touchscreen to enter the network configuration menu. Manually configure the printer's IP address to conform with the new network subnet' pool of addresses . Use 10.0.0.X where X is a number higher than that of you PC.

I should have named the printer.  It's a Officejet 6000 (E609n), which doesn't have a screen.  During the wireless setup process (which I just downloaded from HP), it finds the wireless network by SSID, but even when the network is identified, it sill insists upon 192.168.1.x.  Probably assuming correctly that the new 10.0.0.x network has a DHCP server that assings IP's, the setup program does not ask for an IP.

I should probably mention that I also have an HP6800 on the same network.  That printer also, as it turns out, came from a 192.168.1.x environment at the same time, but had no trouble identifying and connecting to the new 10.0.0.x network.

Who is your ISP?  Please diagram each device on your network including cabling and their associated IP's of each device.

Hi MacWilder,

You can log into the printer's Embedded web server to change the network address manually.  Enter the printer's IP adress in a browser such a Google Chrome or Firefox. In the Embedded web server configuration pages choose the settings page so you can configure the printer IP address. The user guide for the printer explains how that can be done .

I can't login to the built-in web server, because it thinks it's IP is 192.168.1.130, which can't be reached from a server that only see's IP's in the 10.0.0.x range. (I printed out the wireless test and network config pages).  It definitely does see however the wireless network without getting an IP from it.  It also has the old gateway of 192.168.1.1.   In correctly undrstand that the network is open and also correctly notes the routers HW address.

Perhaps the problem is that it states that the configuration source is "Manual".  But I can't change it to "Automatic".

In a response to a request to list all devices on the network, I attach a listing.  Most devices are characterized as connected by eithernet, which is true, but it's through powerline adaptors.  Naturally, the MAC of the printer, which ends in "c6" is not listed.

You should be able to use a laptop to do this. the idea here is to connect adhoc to the printer and not to your wireless internet router. This time just don't connect the laptop to your wireless router for internet. Connect it to the printer's wireless SSID. I have done this before with iPads and  different brands of printers. Once you have made the connection to the web server, open a browser and type in the printers IP address and then modify the IP address. It needs to be within your gateway's pool of IP addresses (10.0.0.x). That will put the printer in the correct subnet and you should then be able to use it.

Another way to attack this is to change the internal address that your router \gateway uses to 192.168.1.100. That is something you should be able to modify in the advanced settings.

What is the device you are using in the image?

Thatnks for the hint.  I fixed it (over wireless actually), by temporarily changing my computers IP to 192.168.1.2.  Then I was able to access the printer's internal web page.  It develops that I had changed the printer's  IP mode to manual and set it myself.  Once on the internal webpage, I was able to switch it to automatic, and that fixed it.  I returned my computer's IP to automatic and that fixed everthing.  

All's well that end's well, as they say.
