MAC Address quagmire

Those numbers cannot possibly be MAC addresses. What exactly are you trying to do?

Assuming you haven't disabled DHCP on your router and do not have over 250 separate devices on your network, those IP addresses are automatically assigned. You don't have to do anything but plug stuff in.

And I still have no idea why you're talking about MAC addresses in the first place. What is the actual goal?

A MAC address looks like this

00:0a:95:d9:26:95

They are assigned to networking devices at the factory and there is seldom any way to change them. In this particular case there is also no need to even try. Thousands of people have networked printers without even knowing what their MAC addresses were.

You're going to have to explain what the problem you're experiencing is in much greater detail if you want anyone to be able to help you solve it.

You are confusing IP Address with Mac Address. Just because the IP Address relates to the Mac does not make it a Mac Address. You cannot change the Mac Address of the hardware. What you need to resolve is using the right IP Address.

Mac Address - The physical address used in hardware to uniquely identify a device. Only required if you set the network security to filter based on them. All consumer network routers are shipped with this option (filter using Mac addresses) off.

IP address - The address used on the network to allow devices to communicate.

When you use the wrong term, you will get wrong answers. I hope this helps.

Ok, Lexmark got back to me with this suggestion and I quote "I suggest you to contact Mac support to change the hardware address of your Mac computer and try to install the driver again."

The latter part of this sentence is the only thing that makes any sense. Have you installed the drivers and followed the configuration instructions in the manual?

What their trying to tell me I believe is that the reason my MacBook and their All-In-One Printer are noy communicating is because the two MAC address are not the same. The one for the Mac is 00:1b:63:04:d9:cd and the one for the printer is 00 20 00 1A 4C I have changed a few letter and numberrs in them both for the query.

The two MAC addresses do not have to be the same. They are supposed to uniquely identify the hardware. Do you really think all computers and all "all in one" machines have the same MAC address? Also, the IP addresses cannot be the same. So, I'm not sure what Lexmark support told you, but what you are conveying is definitely not correct in any way.

My best guess at what they were telling you was that they are not on the same subnet. The first three octets need to be the same, with the last octet being different for each device on the subnet.

the Aiport Extreme is saying 199.

How exactly is your network set up? Is the Airport Extreme your router, or is it only acting as a bridge?
The reason I ask is that if it has a .199 as the final octet, it is not acting as the router. The Airport extreme will take the .1 octet for itself, and distribute IP addresses from 2 to 200. It is getting an IP address from somewhere else and is not serving out IP addresses. Do you have another router in the network? Is the modem a router?

And what happened?

You don't seem to be able to ask specific questions or provide specific answers which troubleshooting by any form of written or verbal communication would require, so really, I think your best bet would be to hire someone to put this together for you.

Hi worksafe,

How about you close this post off, and start afresh, as you are not getting much co-operation here.

Simply start a new topic; How can I get my Lexmark X6570 to print?
