Changing my IP Address, Arris Modem,Router?

[mariokiller64]

Well, my modem has a built in router so it's not separate. I used to be able to change my IP address easily with a linksys router but my ISP, WideOpenWest, recommended this to my dad and of course my dad wouldn't deny tips of an "Expert". I used to be able to change the mac address via router, 192.168.2.1, which changed my IP instantly. Now.......I can't change it at all. I tried this one method where I saved settings, changed the mac address, then loaded it but the IP changes only for about 10 seconds and then goes to what it was before I did the whole settings thing. I tried leaving it off for about a couple hours but that didn't change anything plus it seems like it would be to annoying to change it like that. Can someone help me on finding a fast and easy way to change my IP address.

I have Arris TM552
Firmware Version: 1218
Boot Version: 2.03
Hardware: TM552

TL;DR I can't change my IP address with my new router no matter how many times I try.

You looking to change your LAN IP address, or the public WAN IP address?

Public Wan.

I'm not sure you can change the MAC of MTAs....that's a telephony modem, so your household is getting its VoIP phone service through that. Your phone number ties into your house using a method to identify your house....

What need is there to change your public IP address..there's usually no legit reason.

Personal Reasons.
My IP changed once but not really sure why or how.

Even though your modem gets its IP dynamically your ISP may have you locked to a specific IP they want you to use. I'd say you will have to call them and plead your case if you want it changed. My public IP address has only changed once in 8 years and as far as I know it wasn't because of anything I did at my end. I've swapped numerous routers and it never changes.

Used to change to the way I want it. I didn't have to call or anything. Just a change in my Mac address did it, now this router hates me and controls it.
