|  Dual Cable for home
I have been using Verizon's 7.1 meg dsl (7.1M/680k) for over a year and it runs me about $190/month. I am moving soon and I can't see paying that much for my connection any longer. I run 4... soon to be 5 computers in my home network. I was wondering, is it possible to run two cable lines into a single router and maximise the total bandwidth available to the network. I could virtually have more bandwidth for roughly $100, than I do now for $190.
Save myself 80+ bucks for beer.  |

| Your on the right track. You would need to purchase (or rent) 2 cable modems, as well as a dual WAN router. Of course you will also need to subscribe to 2 accounts from Comcast. One thing to note is that your bandwidth will not be doubled for any one download...rather the router would perform load balancing. For example on the 3 Mbps plan, you could have 2 downloads running at the same time at that speed.

Thanks for quick response. Does comcast allow purchasing of other modems or do they require a specific modem? I'd like to get the best I can if it doesn't matter. I haven't really researched cable modems so I'm at a loss there either way. For a dual wan router do I really need something with a lot of bells and whistles? I'm not running a business, just a bunch of internet junkies. |

Comcast has an official list of approved modems, which can be found here. »www.comcast.com/Support/Corp1/FA···450.html
Basically any DOCSIS modem should work, but I'd recommend getting a DOCSIS 2.0 modem if buying a new one.

No, but either way your going to find that dual wan routers fall in a higher pricing group then regular routers.

Why do you say that a single download wouldn't speed up? The router should distribute outbound packets equally across the two modems, no? Anyway, the router has no idea of what's going on at the application level. |

1 edit | I believe what he was referring to is that you're not going to exceed the capped bandwidth of a single modem for a single download when using a Dual WAN router, meaning two modems capped at 3300 kbps will not give you a single 6600 kbps download (a single download would still max (theoretically) at 3300). The same goes with upload - there is no magic means to say here, half of you go this way, half of you go the other way, and all of you meet up here. (Although I have seen claims of software utilities that could accomplish this.)
One other comment on Dual WAN routers (take it or leave it): you may want to consider diversifying your connections (i.e. one cable, one DSL). In the off chance one goes down, you still have connectivity to the internet. |

Yup, that's what I meant. Thanks for explaining it better then I did.

Many years ago, I wrote routing software and as I remember it, this is basic router 101 - routers send packets to the least congested path. This is how the internet achieves reliability in the presence of congestion or outright failure of a section. You don't have to restart an ftp just because a router somewhere in Missoula went down. If this is no longer the case, we've taken a giant step backward in network technology. |

While I can't say I've ever written any router software, I believe what is happening is that the packets will follow on or the other path, but not both at the same time, therefor you would not get double the speed.

The trick becomes how to split a file on one end, send it to (or from) two different IP addresses, and recombine it on the other end. While routing can be flexible, it is still point to point (source IP address to destination IP address). |

Your talking about OSPF or IGRP routing, yes core internet routers use that method. The cheap Linksys or SMC or whatever brand doesn't use that method for routing. There is the hacked WRT-54g firmware that enable OSPF and BGP routing, otherwise they all just use RIP. |

That's it - if you want the two "circuits" bonded under one IP, then that has to come from the ISP. Some dialups offered this at one time, but I'm not aware of any cable or DSL ISP's that currently offer it. |

If true, then how would two cable modems ever help - even in the two-file-transfer scenario. If the router is so stupid as to choose and stay with one route, won't the 2nd cable modem just remain idle? The router cannot know what's going on at the application level. |

JD would best answer that question. But I assume that these routers start one transfer on one WAN port, then when a second transfer is requested the router automatically selects the second WAN port.
Here is a pretty good review on how these routers work, »www.amdpower.com/sections.php4?o···rtid=103. |

| Forgive me but what do you need all that speed for? I have 10 computers on my network and the only thing I desire is more U/L speed but not so bad that I would go dual. The only reason I'd ever consider dual is for redundancy for when one connection is down.
BTW: if you need even more speed for an aditional $10 a month per account you can get 4300/386. |

There are LAN side requests and WAN side requests. A request goes from my computer to my router to get test64 from OOL's ftp site. Neither WAN is busy, so the router sends a request via WAN1 to send test64 to 68.X.X.X (the WAN1 IP address). There is a second request, this time to get test64.exe from the same site. Since WAN1 is now busy, the router requests that test64.exe be sent to 69.X.X.X (the WAN2 IP address). As the packets come in, they arrive at the router and are forwarded to the 192.X.X.X address of my computer.
The public IP addresses reside in the router and are the public destination (or source, if uploading) of the packets. |
