I am using a Broadband USB Modem the size of an Lighter and was wondering if it would be possible to connect two of this at the same time under Win XP SP2, to increase the amount of data for downloading, Thanks
I would have to say no, the usb modem creates its own connection and has its own ip address that requested web pages are delivered to. A web server won’t know you have 2 ip addresses and will send all the data to the ip address that initiated the request.
If you have both connected at the same time i’m fairly sure that 1 will be used exclusively and the other will essentially be ignored.
That sounds exactly like shotgunning, something you used to do with two phone lines and two dialup modems. How was that possible?
If your ISP supports it, you might be able to use Multilink (http://support.microsoft.com/kb/307849), which is available in XP.
Without ISP support, you can still do something called “load balancing”, but it’s complicated and only really helps with large, continuous transfers that can be split into chunks.
I’m afraid I don’t know an easy way to set this up.
The bandwidth of your internet connection is only going to be as good as the smallest bottleneck in the system. The bandwidth of the average wireless home network is way higher than that of cable or DSL broadband. Therefore, even if you could do this, it is not going to do you any good. Your single USB dongle already has the capacity to suck data from your router far faster than the router can suck data from your ISP.
(And yes, I know a broadband connection don’t really suck, even if it does.)
This would apply to a USB WiFi dongle, but I got the impression that the OP was talking about a USB 3G modem, which should have its own connection through a cell-phone network.
See “bandwidth aggregation”. I don’t think any of these products are all that mature at this stage.

I must point out that OP said Broadband modem, meaning 3G/4G/Cellular. (I must also point out that it’s spelled dongle but that’s not the point!)
I can think of no way for XP to do multilink or bandwidth aggregation on two cell cards. XP has one default gateway, anything else is just a route. You will use one, or the other, but not both USB cards.
Enter hardware solution such as Cradlepoint. However, even Cradlepoint’s flagship router, the MBR1000, which does have 2 USB ports, does not support bandwidth aggregation. It only knows how to do failover. So again you’re using 1 at a time.
So do you purchase yet another hardware device that DOES promise to aggregate bandwidth from 2 ethernet “broadband” sources into 1 ethernet “lan” port? This is the only way you could, however look at the budget already:
2 Cradlepoint routers at $200 each
USB modems $99 each (maybe OP already has these?)
Bandwidth Aggregation Router: At least $179 for a low-end one, but it shouldn’t bottlecap on 2 3G connections. More expensive ones are available from big boys like Fat Pipe.
Monthly broadband service x 2 at what, $60/mo?
It for sure won’t be battery powered or easily portable.
My 2 cents.
Thanks for all the Info, i, indeed have a 3G Modem with a Cellphone SIM Card, sorry that i forgot to mention that, i am in the Philippines and this service is quite cheap with an hourly rate of 50 US cents, and the Dongel is sold at 25$, the transferrate is in the morning around 200kB a/sec. but deteriorates later in the day down to almost nothing at times to be worst around 6-10pm.
