Bridging cable modem

[cinder]

Long story but I'm based in Australia & to use Netflix on a Roku device purchased from the US I needed to change my DNS settings in my router, but my ISP provided Netgear CG3000V2 doesn't allow this as it's a dumbed down modem. Solution was to bridge it to my old Billion 7800N. Also done. Problem is, it has to be connected via the EWAN port which is only 100Mbps as opposed to Gigabit. I have my house cabled with cat6 so it bothers me that this will be a bottleneck for my network.

Would the Asus RT-N66U be a good router solution for maintaining the best speeds possible? I don't necessarily need the 450Mbps wireless so I could potentially get the RT-N56U to save $.

Any advice appreciated, thank you.

Just so I understand correctly, the following (extremely rudimentary) diagram of your network is what you are dealing with;

[Demarc]<-Coax->[Netgear CG3000]<-100Mb->[Billion 7800N]<-1Gb->[Gigabit Switch]<-Cat6->[Other stuff]


As far as I can tell, unless you have an internet connection that is faster than 100Mb/s then you are not bottlenecking anything.

Thanks for the reply. You're right in regards to internet traffic.

But I'm talking about internal network traffic. So when I set up my media PC I want to be able to stream multiple HD content to different devices around the house. I was thinking of building it with 2 Gigabit LAN ports to utilise even more bandwidth. So that's the bottle neck I was referring to when I mentioned the Billion only being capable of 100Mpbs.

As long as the internal traffic is kept on a gigabit switch you will not be bottlenecking anything.

When internal traffic hits that switch, unless it is looking for the gateway, its not going to touch that 10/100 port on the router.

Even if you are using the WiFi on the router (I would have a separate router set up as an AP) to stream to devices you still won't be touching the 10/100 port.


p.s.
Teaming a network card requires a few things;
1. A switch that supports it.
2. A network card that supports it.
3. An operating system that supports it.
4. A driver that supports it.

Granted, there are ways to drop 1 of the above requirements but for the most part you are looking for something called LACP/802.3ad

I would strongly suggest opening a new thread for that either here or on spiceworks to get that ball rolling.

Hi Cloud200,

Well as far as I understood it, once I bridged the original cable modem that loses all router functionality obviously, so all my devices then had to be plugged into the ports of my Billion. Unfortunately those ports are only 100Mbps. So my understanding is that say if I want to stream something from my PC (connected via ethernet through the cat 6 to the server room and into Billion) to my media player (also connected via cat 6 ethernet) then because it's the Billion doing all the routing, it'd be capped at 100Mpbs.

At any rate, I went out and replaced my router today with an Asus RT-66U. I'm not a patient person as you can see! At any rate I've read that bridging a cable modem to an ADSL modem/router is not recommended. That's why I've bought JUST a router.

But thank you for your suggestions

Happy to help Cinder!

I was just under the impression you had more than 4 wired ports. If you do have more than 4, make sure to get a gigabit switch with enough ports to handle every device and only have one port of the router populated with the switch and nothing else. That will give you the most performance.

P.S.
Where did you read about bridging Combo units with Modems being bad? I am interested in seeing if this is real or just anecdotal. Thanks.

I know this is off topic, but I have the same crap modem - I am pulling my hair out trying to bridge the CG300 with my 7800dxl. I put the CG300 into bridge mode and disable wifi. Then run through the setup and choose bridge on the 7800dxl as IP over Ethernet is unsuccessful. How does my 7800dxl need to be configured?

Cinder... Optus by any chance?
Have you managed to bridge the Netgear cg3000v2 to the Asus RT66U?
I am trying to do exactly the same thing with the same 2 routers without success.
I have put the Netgear in Bridge mode and connected Lan1 to the Asus Wan input.
I obviously have to do something to the Asus as although it is saying i have an internet connection, it doesn't, as nothing can connect.
Can you give me a detailed rundown on how you've set this up?
Thanks

Pete.
