Thread: Two ethernet card on one computer to make internet connection

I have one windows xp computer and it has two ethernet card.
I have two different internet service provider.
So, basically i have two internet connection.
One connection has static ip and one has no static ip.
A static ip is configured with different router and it is configured on 192.168.2.1 and other one is working by obtain ip automatically. So, it is working on 192.168.1.1.

How may i connect these two different connection to make it work on one computer for using lan and also wan

Only one ISP will work at a time.
Usually the one with higher speed.
if it fails other takes over.
Speed will not add up.
Clarify

using lan and also wan

Also you should be using two different modems.

Basically, from those two different isp. I am using one router with internet connection is for dedicated to lan and the other router will use for dedicatedly for internet connection.

So, how may i use the two different routers for different purpose on single computer? To work lan and wan also.

I am using Airtel/BSNL IP's
Modem used Beetel 110BX1.
Both ISPs settings are entered in WAn page etc.
I simply change the RJ11 to concerned ISP's
Phone junction.
Only a single modem used.

If you have two internet sources (like one dsl and one cable modem), you could use a pep link balance multi-wan router to take advantage of both at same time. You could also setup the pep link to channel VoIP over whichever Isp had lowest latency/jitter.

Yes, i can but the thing is different.

Please look at this scenario.

1) broadband connection (isp) ==> isp modem ==> local router (befsr41) ==> switch ==> all computers through one domain ip to make it lan.
It has static ip

2) broadband connection (isp) ==> isp modem ==> local router (befsr41) ==> single computer
no static ip

now, i pick one computer from my lan connection and that computer has two ethernet card. So, i am using two different cables to connect with my computer. One is from broadband connection 1 and other is from broadband connection 2. I have bridge the connection for both connection into my computer. Now, i have plugged out for internet connection. To verify which internet connection i am using. Connection 1 or connection 2. Now, i have verified that i am using connection 2 is working but i am not able use my lan. so, how may i use my lan and also in parallel use connection 2? still, i have plugged out my internect connection 1.

There is a software named OCTOPUS+ , which helps in connecting to more than one internet connection at same time.

OCTOPUS+ will help in utilizing all the active internet connections available in a computer. OCTOPUS+ will intelligently manage the traffic between a computer and the internet among the available active internet connections. This will ease out the congestion through each of the active internet connections and thereby maximizing internet traffic throughput

Google OCTOPUS+ to know more

Simplicity needed here. Forgive me for going back to basic building blocks.

LAN = Local Area Network. Call it everything inside your house (as long as it is connected, of course)!

WAN = Wide Area Network. Call that everything outside your house.

ROUTER = something that routes traffic from/to one network to/from another.

You can have as many routers on your LAN as you like. Each must have a unique LAN IP address.

If your operating system allows, you can have as many NIC (network interface cards) on your PC, and all of them can be connected to your LAN, but each must have a unique IP address.

Keep it all on one "network", ie 192.168.1.n (subnet 255.255.255.0). Use a switch/hub to connect it all together (possibly the one that is built in to one of the routers?).

You may find this easier to handle (and understand) if you give all your LAN devices fixed IP addresses: your routers will have to have fixed IP addresses on their LAN ports.

Is any of this worth it? ...

I'm inclined to think that it isn't --- but I have no experience with software such as octopus+ just mentioned, which might make all the difference. In another thread, someone else mentioned another software, which, for downloads, looks for mirrors and then manages the download from multiple sources across multiple connections. This approach could work for torrents, too

To be honest, it is something I'd like to try --- not enough to invest in another broadband connection, modem, router, etc! I'd like to make it work, as a challenge, but my usage pattern wouldn't merit it anyway.
