I was just wondering is it possible to have two seprate nics downloading from the internet on the same computer via a router effectively doubling your speed or is this just a fallicy that i have conjured up in my mind?

I know on Linux it can be done with software and router setting. Do not know with MS Vista.

not with ease
i am sure there is software that would do it though

there is a easier way to speed up downloads. But as of useing two nics to get packets an what not???

There was this guy making this thing that was basically raid for internet, but not sure if its out yet, and you need 2 separate internet sources, like cable and dsl. Also, I would like to know how to do this on linux

squall_01 · « **Reply #5 on:** August 29, 2009, 08:15:55 PM »

but your suppling two differnt connections its not one. Thus in so its not going any faster just allows for you to use a differnt one

ya i didn't think that there was any way to do it... since i have tried many different configs and settings trying to achive this

smeezekitty · « **Reply #7 on:** August 29, 2009, 11:07:51 PM »

even if you did get it working it wouldnt be that much faster or relyable
i would say its not worth it

I'm sorry but it not possible and it would also not increase your download either

The answer to your question is no.

You just post whatever comes to mind, don't you? Does thinking ever come into play?

squall_01 · « **Reply #11 on:** August 31, 2009, 09:01:07 AM »

not too much with him. Like I said there is a way to speed up downloads but no possible way to use two connections like that ibid.

talontromper · « **Reply #12 on:** August 31, 2009, 09:56:10 PM »

how can u speed up the downloads if the modem is a fixed speed. besides flashing the modem with a different profile there no real way of that i know to increase speed.

squall_01 · « **Reply #13 on:** September 01, 2009, 04:18:33 AM »

its an app that prefects some of the data. Your not really increaseing the speed of the connection but it does do it faster cause of that.

Allan · « **Reply #14 on:** September 01, 2009, 05:41:45 AM »

prefects?

squall_01 · « **Reply #15 on:** September 01, 2009, 10:30:15 AM »

sorry, prefetches

First of all, it is possible. Has anyone ever heard of a T1? A T1 is 24 phone lines bundled together to get higher transfer speeds.
Second, did any of you actually do any research before replying to the question?
Here is some open source software that allows you to put multiple connections together to achieve higher bandwidth. It's been around for quite some time now.

no, we used pure logic here

$:-\$

wbrost · « **Reply #18 on:** September 02, 2009, 10:52:12 AM »

that will only increase the speed of the local link not the external link.

in windows you can "bridge" the connections into a single logical interface. This will not increase the "Internet" speed.

on a layer 3 switch and router you can "trunk" the ports.

Neither of these will increase the internet speed. They will increase the intranet speed however.

True.... If you really wanted to take advantage of a program like firehose (which I linked earlier) you would need multiple internet connections. Otherwise, there would be no point.

How does bridging or trunking increase network speed though?

on the PC bridging links the two NICs together and forms one with double the original link speed. example would be two 1GB cards working as one to provide 2GB. The same theory applies to Trunking.

Yeah, like Percy Weasley in "Harry Potter."

I think he means "prefetches."

squall_01 · « **Reply #22 on:** September 02, 2009, 02:00:47 PM »

what?

Any way he stated that he had two connections. I thought cause they were seperate that you couldnt tie the two together to get the data packets to come threw both of them.

an example would be, if you had a gigabit WAN connected to a router and two 100mbps NICs in a PC, using both would be faster.

But, No consumer oriented Internet connection(that I know of) achieves even more then 100mbps.

I was answering the original question:

If the OP is using a standard DSL or Cable connection, chances are their connection does not exceed the 100mbps throughput that their NIC is capable of- assuming it is "only" 100mbps.

The question is basically asking wether it will be faster. It will not, for any consumer-targeted internet connection, allow for faster speeds. In order for it to do so:

The Internet connection itself must be higher then the total throughput of the NICs.

the Router must support gigabit (otherwise it's WAN interface will only be 100mbps as well, limiting the total traffic to all LAN connections to 100mbps regardless of the actual capabilities of the Internet connection).

both NICs must support simultaneous usage... not so much a problem now since IRQ/DMA contention is now a thing of the past.

However, on the other hand, most PCs now come with an on-board gigabit connection, in which case two gigabit connections will NOT increase the speed of downloads.

I think you've got a bridge confused with something else: http://en.wikipedia.org/wiki/Network_bridge
Might want to check out trunking, too. Maybe link aggregation?

what are some of the fore mentioned programs?
