Netgear WAC124 New Spectrum modem connection

Hello all,

 

It seems spectrum is sending out new modems to a lot of people, the email I got from them says if I don't do it. They will just disconect the internet. So I got it today. Everything was fine until I switched. I had to conect my pc directly to it and call them. They asked for the mac address and boom after 10 to 15 anoying minutes it worked, I unplugged my PC put on the Router cable with with my old WAC124, no internet. Switched back to pc directly, internet. reseted the router no internet. unplugged everything and plugged everything no internet. I used my pc to go inside the WAC124 settings and changed the mac address from the router to my pc's mac address. BOOM like magic there was internet. Did Spectrum blocked my routers mac address? if so why? it is anoying specially since I bought that piece of . equipment no long ago.  I know there are spectrum specialist reading all these blogs. I need an answer,

Re: Netgear WAC124 New Spectrum modem connection

Spectrum did not block your router per se, this is their method of securing your connection to their internet. As I understand it the MAC address of the device connected to the internet when the modem is provisioned is locked into their system and that is the device that they expect to see connected to the modem. This has been the way it has always worked for me.  The solution to this is exactly what you have done, clone the MAC address of the original device to your router. If you needed to change the address Spectrum accepts you would probably have to reprovision your modem.

Re: Netgear WAC124 New Spectrum modem connection

You received a new modem because your old one was technically obsolete or incompatible with Spectrum's network.  Any time you change from a computer to a router connected to your modem's LAN port, you MUST reset the router to its factory settings before you restart your network.  Normally you just hold in the router's reset button until the router LEDs flash, but a few makes including Netgear do require you to hold the reset button continuously until the unit resets TWICE to get all the way back to factory defaults.  The manual supplied with your router includes detailed instructions, or use this link to the Netgear website:  https://kb.netgear.com/000060511/How-do-I-log-in-to-my-WAC124-for-the-first-time

If the above instructions don't work you can always try the 30-30-30 reset as follows:

  1. When router is powered on, press the reset button and hold for 30 seconds. (Use a paper clip or something sharp)
  2. While holding the reset button pressed, unplug the power of the router and hold the reset button for 30 seconds
  3. While still holding the reset button down, turn on the power to the unit again and hold for another 30 seconds.

This process usually works for resetting any router to it's factory setting.

Re: Netgear WAC124 New Spectrum modem connection

Hey thanks for responding to my question... But that is the problem. My WAC124 (router) was the original device connected. The PC is the newer equipment. What you said would have applied if I had a problem connecting the New Modem with the New PC since there was no record of the mac address. But in my case it was my router. It was working perfectly fine. OLD Modem - Router - PC. They sent a new Modem. NEW Modem - Router -  PC. Switch it, no internet had to call to set it up since the selfinstall was not working. Per customer service I had to put it like this: New Modem - PC (no router).  Internet working at 200Mbps I switch my pc with my router and now it looked like this: New Modem - router - PC and no internet. I reseted it, I unpluged everything.  No internet. Went back to New Modem - PC and it had internet. Now I looked at the lights on the modem and I saw it was talking to my router, but it was just not internet at all, so thats when I figured ok what if I make the modem think its talking to my pc instead and I switched the MAC from my pc to my router and like and off to on switch I have internet access from my router. My question is why. it worked perfclty fine with its original mac address on the old router. why is not doing the same on the new one. Why I have to put another hardware address for it to work? for what you said I would have spected my router to work with it and not the pc. Now I am using wireless but what If I need to plug my pc to the network? is there going to be a conflict?

Thank you for this info. Ill try that 30 -30 -30 thats the only thing I did not do. Changing the mac did the trick but I'm interested in this 30-30-30.

Re: Netgear WAC124 New Spectrum modem connection

When you get a new modem all the previous information about your setup Spectrum has is discarded. A new modem to them is an entirely new setup so they start from scratch. When you plug in the new modem and call them they look for that modem and provision it and unless things are different now that involves them allowing the modem to connect to their network and at least in my experience they lock it into the MAC address of the device connected to it. I assume they want it to be a PC is because that is easiest for them. It is only one device they may have to troubleshoot if something does not work. If your previous setup was with the router as the first connection it might have been because a tech was there during setup and he was more willing to do it that way or you might have gotten a better tech over the phone, that I don't know. 

There will be no conflict having a cloned MAC address on your router. It is done all the time. The only one who sees your cloned MAC is Spectrum. Your local network will not be effected by that. Just plug your PC into your router and things will work fine.

 

Also every device ever created has its own unique MAC address. Your old router had a completely different MAC address from your new router and your PC has a completely unique address from the both of them. That is why routers allow cloning addresses, because some cable companies are very strict about what connects to their networks. They used to use this ability to limit the number of devices that could be connected to their networks. Some companies used to charge you more if you connected more than one computer to their network. No cable company does that anymore but I think that is why some of these setups are the way they are.

Re: Netgear WAC124 New Spectrum modem connection

In my experience the only MAC address that is "locked" is the modem itself, which is why you have to call them (or maybe attempt the self-activation) when switching.

 

They do remember the MAC of the device connected to the modem, but only for DHCP, so it assigns the same IP again.  If you change the MAC address/device connected to the modem you will still connect, but with a new IP.  I know this because I spoofed my server's MAC address a number of times over a couple of months when trying to debug an issue I had.

 

Cheers.

I am a local IT Consultant in the Hudson Valley of New York, retired from IBM with over 40 years in the industry.

I've never had to perform a factory reset on a personally owned router when connecting it to a cable modem provided by Spectrum.

When I have had problems similar to yours I

update the router firmware to the latest version

as well as clone the MAC address from the last connected device recognized by the cable modem to the router. 

That seems to work 99 percent of the time.  Not all areas served by Spectrum have the same requirements with MAC cloning.

Re: Netgear WAC124 New Spectrum modem connection

If you received an E31 modem, Spectrum sets these to recognize only one MAC address at a time. If you switch the device connected to the modem, you must reboot the modem before your router can obtain an IP address again.

 

Also, in some markets, if your router sends too many DHCP requests in a short amount of time, Spectrum won't answer your request for an IP address. Leave your router unplugged for a little bit (5-10 minutes) then boot it back up.

Re: Netgear WAC124 New Spectrum modem connection

Could be stale ARP cache data or a new DHCP lease linked to the MAC (think Spectrum still runs 30-day leases?).

Either a cache clear by full power down for 5 minutes and a sequential boot (fully boot JUST the modem, then the router) or resets to factory usually will clear it up. On occasion, the router may need a second reboot though.
