possible dual internet connections?

I now have 2 internet connections on my laptop, ethernet from cable company and wifi from verizon DSL. I am wondering if my computer can utilize them both at the same time?
ps. 2 different companies.

 

You mean like getting them to add up so you'd get double the speed?
I don't think that's how it works...

Maybe you could use both at the same time for different things (like two downloads each using up the bandwidth of each connection) but I don't think you can just add up two internet connections together like that...

 

Thibault, I actually looking for a solution which allows me to use cable connection for download and wifi for web surfing.

 

That might be possible... Sorry I can't help you as I have no idea how you'd pull that off but it doesn't sound unrealstic.

 

Why not? Did you try it?

 

I don't know how to.

 

1+1 does not equal 2 in download speed. You can only have one source active. The two connections cant just team up since they dont know how to communicate with each other. Which does what?

 

The question is not gear to double internet speed, there are two different Internet connections, one DSL and one EVDO, therefore two different AP's equipment and ISP.

 

its really tricky. The only thing you could do, though i have never seen anyone in practice actually set this up correct is have 2 nics on your computer and configure one for uploads and the other for downloads.

 

that's not possible without doing some major mods. basically your comp would need to interpret and process the signal from two different sources and they're not made to do that. not worth the trouble in my book

 

**THINKING LOUD **

This must happens at the Transport layer (TCP), the protocol must take care of both request at the same time, let's say you have two FF3 opened, then you type one web site in one and another web site in the other, then you press the enter, upps, you don't have two enter keys!!!! And when you are active in one window, then the other window is in the background sort of speak. How can you have two active windows????? Can we associate one core with one window and the second core with the other? Ok, is time to go to bed

 

basically here is what i want, flashget via cable, firefox via wifi. what do you guys think?

 

I think it will work, the Transport layer will multiplex to pay attention to one process and to the other. The last layer 7 is the one with the applications, so it will have two of them (http and flashget), then when the encapsulation starts TCP will take over, but it will multiplex using both pipes, then the final MAC/LAC and Physical layers will handle the frames. What I'm trying to say is that one process will use the cable at t1 and then WiFi at t2, and so on, the same for the other process, depending how the lower layers are allocating the physical resources, hmmmm, is very confusing, why don't you just try it?

PS: The above is merely speculation

 

I don't know what to do.

 

What do you mean, just do the connections, open one IE or FF to surf, and a window for flashget and start both processes and see what happens.

 

This is what you want to use

It's a dual wan router. You won't combine the connections though.

 

One question, when you say wireless connection, do you mean EVDO?

 

I have had dual NIC before and it allowed me to be on two networks at once, and each network could have its own internet service.

Still tho I never found any special way to split my internet use between them.

 

Using one computer only and two different AP, I can see the advantage, but it requires an additional application to associate one process with the wireless nic and the other process with the Ethernet card. This is a good opportunity for programmers.

PS: Assuming that both AP's are of comparable speed. If AP1 is much slower than AP2, then is better to multiplex both applications on AP2. In other words, cable is much faster than EVDO, in this case is better to keep both applications running over cable.

 

If you were able to convert the signals to 10/100BaseT before your PC you could use a SMB Router like Netgears FVS-538. It supports 2 seperate ISP's and give the options of load ballancing & roll over. The FVS338 (I have) supports 2 but one must be a serial connection.
