One PC and Two LAN Cards

If you're using Windows each network card will show up as a "Local Area Connection" and you can configure them using the network administrative tools.

If this is for a home PC it wouldn't make any sense setting up switches hubs or routers along with software to attempt to do what you wish. They all end up going to the same transmission line anyway. If you had 2 PC's, depending how you set up a hub or routers or bridge, would allow you faster data transfer. Other than that stick with what you have working off 1 LAN card. You would need 2 IP addresses and unless a query knows where to be returned to it would come back on the same line.

Considering your question, I would agree with other comments: stick with one card.

However, would you like to go for a clear cut between different services e.g. split VoIP and pure web surfing over your two separate lines, you would have to configure your PC cards to make them operate on a separate sub-network, and you would need your router to be configured with QoS to forward the traffic according to your needs -which means your router has to have QoS.

Gents...

Thanks for your responses...

I'm looking for the easiest way do so...is it by have "Load Balance Router" then connecting both accesses to it and configure it to use one connection for transmission and the other for receiving (if possible?????)

or to have two PCI cards in one PC and make a special setting to do what i need or having a software to manage those connections (if its available??????)

Each network jack you see on the computer has 8 wires.

4 are used for network communications (the other 4 you don't need to worry about)

They are split in to two pairs.

One pair is for transmit.

The other pair is for receiving.

Each of these pairs can go at the full speed of your network connection (100mbps if you're plugged into a typical home router). Technically trying to transmit from one card and receive from the other would NEVER go any faster than just using one card by itself. A 100mbps card should transmit at 100 and receive at 100 (so it 'actually' is moving 200mbps back and forth)

The only time you'll see parallel network connections between computers is in high end server setups where you simply need more bandwidth than what one network card can handle. Specialized network cards are available that have several female network jacks. Chances of needing something like this at home? zero unless you just like to brag...
