Yes that is the right section to change your MAC, but to make it even easier you don't have to change the MAC unless it won't change the following way. Go to status and click disconnect. Wait about 30 seconds and click connect. Before you do that go to ipburger.com and also go there after to see if your ip changed.

Thanks folks, I'm going to wait until everyone leaves the office to try this.

I'll let you know!

Somehow, I knew this wouldn't be simple. :smash:

Lakeman, I tried disconnect and connect - no use. Also it says "DHCP Release" and "DHCP Renew" rather than connect or disconnect (if that makes any difference).

Before I go any further, I am going to call the landlord and cable company tomorrow. I think it'll be easier just to ask them if he has a static ip or not.

Turns out he also switched his pbx over to Optimum online also. So instead of the standard cable modem he used to have like most of us, now he has a Motorola "SBV5322 SURFboard" Digital Voice Modem (about 2-3x fatter than a reg modem). On the back, there are 2 pairs of 3 wire phone lines going into 2 different ports. Other than that, the other connections are the same as a standard cable modem. Coxial for cable, Cat5, power, etc...

Still, without more knowledge, I don't want to **** with his network, internet connection and now possibly his phone system too.

LMAO, I could just see it now....:laugh:

Thanks folks, but for now I'd rather play it safe today.

PS: I came THIS close to unplugging the modem, but I didn't want to potentially take his ENTIRE company down. Chicken ****.

I will be here for another 15 mins, so if someone who is an expert in Telcomm/IT, can 100% say that disconnecting this modem is safe, then I will try it.

Telcomm/IT = TIT expert? Oops...is that allowed?

How long did you leave it after you clicked disconnect?

If it is a cable modem, DHCP release won't do it unless you release for 6-24 hours, then renew. You need to change the MAC for in your router in order for the cable modem to re-provision a new IP.

The IP address you mentioned way up there (69.116.xxx.xx) is the WAN IP which belongs to the line itself. That is what you want changed. You local ethernet IP is also called the LAN IP and is the IP of the ROUTER. Go back to your wireless connection in your system tray. Right click, choose status, click the support tab, look at the very first number. Skip the next number and look at the one after that.

WAN is how the world sees you. LAN is how the network sees itself. You don't have to understand any of this for it to work. You can simply do it, and figure out how it works by thinking it backward after-the-fact. Access your router using the LAN number. Change the MAC, and the cable modem will get a new WAN number after you reboot it.

As odd as it sounds, changing a number in one unit for one kind of thing causing a change to a different number in another unit entirely, well... that's how it works.

If you analyze it, it will make no sense. If you do it, it will work. Stop thinking.

http://192.168.1.1 - log in - change mac in the router - reboot the cable modem (not the router).

Done.

I left it for about 15 seconds.

Try 60 seconds, most of the time I have to leave mine for around 30 seconds.

While I wait for the info from Cablevision,
IF I get lucky and his service is in fact dynamic,
will changing the MAC addy affect his phone system I mentioned?

Thanks for the help.

If his phone system is VOIP, it has it's own MAC that you can't change from within the router. You will only be able to mess with the MAC that belongs to the LAN/WAN portion.

If his phone is not VOIP, then definitely no worries.

Are you sure those are phone lines and not Cat5 or something else? Now I'm getting curious about that setup.

Yes Vic, I know for sure they are phone lines.
He has 5 inbound lines coming through his VOIP phone thru Cablevision.
As I said, the modem is a FAT Motorola SURFboarder - digital voice modem.

Ok. Somewhere along the way I missed the part where you said VOIP.

But it's OK, since the VOIP circuit has it's own MAC addy separate from the LAN/WAN.

Aren't you at least reassured that I was asking questions in return?

Yes! :thumb:

I'll report in later. Thanks again.

Well I begged for him to call Cablevision and the ratbassturd said
ok, ok...then he gave me some weak-azz excuse about how he had
to leave early and that he would call on Monday.:rant:

So I said, F him, I changed the Mac addy and rebooted the
modem after he left. lol

But no luck...

1- The freakin' modem has a backup battery/power supply
because when I pulled the plug, the modem still had the power indicator light on.
Although the other lights went dead, power and the "battery" lights were on.

2- When I replugged the power to the modem, I couldn't get any internet connection.

3- Lakeman - I tried releasing for 30+ seconds....that didn't help.

4- When I put everything back to the way it was, internet was back and the IP was still the same.

I guess I have no choice but to wait for Monday. :ballchain:

Thanks again for all the help. :thumb:

I'm outta here! :faint:

PS: On a COMPLETELY unrelated note, I have cheap tickets to the
Elton/Joel concert in Wrigley. LOL - I do!

It's the backup battery that is getting you. Remove that and reboot, if you can. Or unplug it and let the battery run down. Might be a few minutes, might be hours.

Or force a reboot by unconventional means. A change to the router name "Motorola" to "Notorola", save. Should reboot. Then set it back and save again. Doesn't work on all units, but does for many. One Step Zup would do it from the MIB OID panel.

I'm beginning to suspect your landlord is blowing smoke and has no idea what his connection parameters are, and understands your situation even less. Most people deem something unimportant when they don't understand. So, keep an open mind. If you can't appeal to him, try to go around him another way.

Ladies and Gentlemen...

We have lift-off!!!

New IP Addy!!

Now I just hope on Monday, my landlord's systems run normally. :)

If not, this will be my last post. LOL

Thank you for now, if I am alive on Monday, I will "Thank" properly.

Termed

PS: I decided to just "go for it" and hope nothing bad happens.

:thumb: Let's expect a welcome back on Monday. Seems this has worked :cheer:

AHEM......you guy/gals ROCK!

My landlord didn't have ANY problems.

I made sure and asked him if all his telcomm was working properly.
I didn't even tell him about the ip change!

But Vic was right....it was the battery backup.
I changed the mac addy, removed the battery, unplugged the modem (not router), waited about 5 mins....and WHAM! New Addy!

So I wish to thank (and will be thanking ) all those who were kind enough to help me along the way.

Sincerely,

Termed.

Now, jot down everything you did, stick it in a notebook or save a txt file. So when you need to do it again, you'll be able to do it again quickly without missing any steps. If you're anything like me, you figure something out but by the time you need to do it again - you've forgotten at least one important step and end up relearning the process all over again.

Vic,

After I joined this board, for some strange reason,

I have a LOT more spreadsheet files. :ninja:

:peace:

Glad you got the ip changed! :cheer:
