Q on networking

[OODA Loop]

I've seen motherboards with dual Ethernet jacks (mine being one of them). And i have always wondered if it does any good. or is it just so you can connect to two networks.

i came across two draft n network cards and i wondered if i could use two and would it work the same or should i just wire my house for dual Ethernet? And what performance does it reap?

I believe the main purpose is for you to be a mini router. So Modem -> You -> Another Computer. But hooking up two internets into your computer? That would require some software.

You can connect to two networks, I dont know about connecting to two netlines.

could be used to...

connect to two networks
some allow you to team them together 2Gbps connection
bridge them like a switch and daisy chain computers together
failover, incase 1 goes out
make it look like an awesome feature to make you spend more money then you have to....

that covers it

I used my old comp to be a router to my 360 and parents comp when we had our old internet (usb to comp)

gasp :0 thank you

but would it work with wireless?

No it wouldn't.

If you have normal home internet access, two jacks won't do you much good unless you are building a firewall/router of your own.

It's mainly useful when you need to bridge two different networks.

Teaming connections only works if you have 2 outbound internet connections. Which most people don't.

Wiring two wires from your computer to the router should work (I've never tried it), but it won't do you any good. A standard NIC will run 10x faster than your internet connection, so having 2 wires won't help you at all.

And wireless ethernet is different than "ethernet ports."

In fact, I would wager that having two wireless cards in your computer would degrade performance, not improve it.

double gasp :0 no, thank yooou

so it would only do good if i needed to transfer large files over my network...

k thanks people

well not only good for lan features, like they said before, it's actualy quite beneficial if you have 2 sources of the internet, (2 separate cable internet modems running in your house, however, most installation techs dont realize that when you have multiple like that, that they are supposed to increase your UL cap running to your house, so if you decide to get multiple, make sure you ask them to increase your cap

It's most of the time cheaper to just get a better connection than to try and shotgun a bunch of connections together. ( like getting a T1 is cheaper & better than 255 channels that it's made up of. )

Switch from residential to business class or upgrade your service. I know for ME to double my speed - I only had to add an extra $10.00 / month to my monthly charges. To add a SECOND cable line - it would have cost me an extra $60 a month.

Not exactly worth my while when my max speed thru the *ROUTER* is a whopping 10mbps - which is WAY faster than my internet connection. Using multiple ethernet cords out of the router is thus, worthless.

The main purpose of multiple connections is high availability, load balancing, connection sharing - and that's about it. Business feature.

You *can* bridge LANs together though.

But why you wouldn't do that kind of stuff with a standalone router, I don't know. (Router: smaller footprint, less power consumption, easier maintenance, overall more efficient.)

I'm building my own gateway and I have to have 2 NICs, I'm getting rid of my router completely... with the gateway I'm building I'll have spam/e-mail/virus protection before anything even hits my network and also logs and better firewall support. Also my gateway would be able to handle a lot more users then a regular router would.. but of course it's not something an average residential setup would have...

I have the fastest connection possible without going business class in my area... and they said switching to business class for me would be a LOT more expensive if I wanted to achieve the speeds that I already have...
