IP won't change

Redsox19801 · 08-19-2008, 03:20 AM

Hi, I have been trying to change my ip address for a long time now it has always been stuck at the same one for over 6 months now. When I log onto my router it says my connection type is: Automatic Configuration - DHCP (Dynamic Host Configuration Protocol). I have tried unplugging my modem and router and letting it wait. I have done DHCP releases and then renewed it. I have tried cloning my mac address. I have a Motorola SBG900 for a modem, which gives off a wireless signal as well as having a Linksys Wireless-G Broadband. A technician came to fix our internet one day and for some reason if just the modem was plugged in into the computer without using the router at all the internet would not go. Since then though I reset the factory defaults on the modem. If you have any advice on what I can do to change besides calling my Isp and asking them to, please post. Also, I need to change for personal reasons :S Let me know, thanks.

For the record, my lease times are obtained at a certain time and expire exactly 24 hours later.

Hi Redsox,

When you cloned the MAC, was that on your router or the ISP equipment? What device actually gets the IP address in your case? The SBG900 or your router? If your router gets the IP and you cloned its MAC and still got the same IP, then they're assigning the IPs via the SBG900. If you cloned its MAC and still no change, then they're assigning the IP via the SBG900's ESN number or something similar but not the MAC address.

If you switch out SBG900s or go to a different cable modem altogether, I'll bet you'd get a new IP. Are you leasing that one from them? If so, go buy your own and turn that one in. Now, the equipment is yours, and you'll probably get a new IP. Notice I said probably.

When I am changing the MAC address it is from the router, but from being logged onto the modem I am not seeing that there is an actual option to clone your MAC address like there was from my router. It gives me all of the information it just doesn't exactly give me an option to change it. Both my modem and router are owned by me and are not my isp's equipment. Are there anyways I could change the modems MAC?

wimiadmin · 08-19-2008, 12:27 PM

Which device is getting your IP address now? The router or the modem? If it's the modem, does it have a pass through option (gateway) where the IP will be assigned to the router instead. If you can do that, maybe you'll get a new IP, or then try cloning the MAC of the router to try and get a new IP.

I'm not familiar with any admin type login for the surfboard modems to change the configuration.

Not seeing any option to do that but I log on my modem using the default gateway for it (192.168.0.1). It displays a lot of information just doesn't offer ways to change it like my router does.

Redsox19801 · 08-19-2008, 12:42 PM

It is my modem that is getting the Ip I am pretty sure considering changing the MAC address on the router isn't affecting my IP.

Redsox19801 · 08-19-2008, 12:49 PM

Do you have a chat server or MSN or anything we could talk on to speed this up and I can give you more details there.

wimiadmin · 08-19-2008, 04:44 PM

There's really nothing further we can try. You're correct though in saying that since the modem is getting the IP then cloning the MAC on your router will have no effect.

Your last hope may be to hack your SBG900.....but be VERY cautious. To find any hacks, you can Google SBG900 hack and see if anyone else has been successful.

Sorry my help was limited.

Okay I think my Isp makes it really hard to change on purpose so they can keep track of everybody because if they can't track who did something they have to take the fault.

Probably a static IP Address.

Redsox19801 · 08-27-2008, 12:02 AM

No. DHCP stands for Dynamic Host Configuration Protocol so it isn't Static but anyways I gave up because nothing works for me and nobody can figure out a solution.

Actually that's not entirely true. Normally DHCP is assigned to give a dynamic address from a pool as you've said, but it can also be set up with "reservations" so that if a specific MAC address requests an IP it will always assign it the same IP.

It's obviously a lot more admin time to setup that up, but I wanted to point out it is possible and depending on the network admin they may have decided that the advantages of knowing what IP is where straight away is worth the admin time.
