BYO Cable Modem

Answered

Good afternoon everyone,

I'm looking to replace my cable modem/router to one not provided by Telstra as the provided ones are having too many issues scaling with my growing network (performance/stability issues). I have recieved mixed responses from Telstra employees about exchanging modems. I will be using a DOCSIS 3.0 Motorola Surfboard 6141 as a modem and an ASUS AC67U as a router. This post is just to confirm that I am able to change modems and still use Telstra's Ultimate Cable service but I accept that they will not be able to be patched by Telstra. I'll be keeping my old modem around to assist Telstra in diagnosing my network if needed however I'm confident I will not be having issues as the only times I have had to call customer support was regarding the cable lines outside of my house and not the hardware itself.

 

TL;DR: BYO Cable Modem. Can I still use Telstra service?

It is possible that if you set the MAC address you can use your own modem but my understanding is that if it doesn't work and you have problems with it that there is no support for non-supported devices...

Re: BYO Cable Modem

I'm pretty sure you'll be told no because your device won't be on the list of authenticated devices.

However doesn't hurt to ask.

Re: BYO Cable Modem

Thanks for your reply. The issue is that I get different answers depending on who I ask. I'm capable of installing the hardware and submitting the HFC (Cable Modem) MAC if that is whats required of me, I just don't understand why it would pose an issue. I'll ring Telstra again soon but the technician that came to my house recently said yes, and the Telstra support operator I spoke with before that said that "It wasn't advisable" so I just want to make it 100% certain before I drop $100 on a modem and $250 on a router.

The answer is most certianly no, if they see you are using a non-bigpond supplied modem, they might blacklist your mac address so you can't connect it to the internet.

 

I would be very wary to try your own modem for cable

If this is indeed the case I will have to switch providers. I cannot work with my current router and modem that collapses under my network and lacks support for my VPN.

You can put the modem into dumb mode and have your own router.

 

The Netgear CG3100 "thing" I have is a terrible device. I turn off NAT, and the wireless, and put a few layers of black electrical tape over the lights, and I don't hear a peep from it (unless the Telstra network goes down).

Just as per conversation with a Rep

 

"I understand that you want to check the compatible modems. No worries, I'll be more than happy to assist you. For Cable Broadband service, BYO modems will not work, only Telstra supplied modems as the MAC address of the modem needs to be registered first in the system and associate to your account to make it work"

 

Hope this helps

Re: BYO Cable Modem

I know it's been agessss since you posted. But, what I do is turn NAT off on the Telstra supplied router. Then Connect a Cisco 1841 that picks up the IP address from Telstra's DHCP server. All of my NAT, IP access lists, DHCP and VPN are done on the 1841.

But, it's super gay that they don't allow BYOD. The thing that pissed me off the most was that I can't change the DNS server on the Telstra Netgear. Telstra DNS is mediocre at best. 

If you couldn't be bothered fighting for your right to use your own device, I would suggest just using it as a bridge. Then all of your routing decisions will be made by the router of your choosing and the Telstra supplied device wont have to do anything strenuous.
