Mobos with 2 LAN ports. If connected to the same modem, do they make you go faster?

[jonnyyyl]

I've seen some mobos with 2 10/100/1000MBps LAN ports, if both are connected to the same modem and service provider, would they theoretically make you go faster, or seamless?

 

Say in scenario 1, my subscription is a 500MBps package, if I have both connected, I can have each port running up to 250MBps, so long as I don't exceed 500MBps. 

In scenario 2, if my subscription were 250MB, the highest both ports can reach is 250MB, roughly 125 each?

They are redundant, so if one of your cables breaks or something the other will keep working and you will still have internet connection.

It does not give you any more speed than if you only had one port.

First of all, make sure you use the right units. 1 M-Bytes-ps is equal to 8 M-bits-ps

Depending on your OS you could tell certain applications to use one connection over the other, nit really sure what advantage you gain by doing that though.

Just leave this here for your reference

this doesn't make sense. if the ports are gigabit speed, which i can only assume they would be because putting 10/100 ports on a half/gigabit connection would be retarded, then your cap is the "subscription" rate, not the NIC.

Linus explained this, sort of, in this LTT Video:

The ports in the back of your modem or router are basically part of a network switch, there's a hidden "network port" that connects the switch part to the modem part.

So no matter how many devices you connect to the modem or router, to the ISP you appear as just one device, the modem or router itself.

You can even plug switches to the ports in the back of your modem and then plug computers in those switches..

 

No matter how many devices you plug in you'd still have the maximum speed the ISP gives you, which is configured and limited in the modem part of the equipment.

 

So you won't get faster speeds but what you could do for example - if the modem/router is smart enough - would be for example to configure quality of service rules for different ports (or IP addresses) in the back of the modem.

This way, you'd create special rules for one port that connects to one of your computer's network cards to be optimized for gaming, and another port that connects to your other network card to be "optimized" for streaming netfix..and then you would configure games to use one of the network cards exclusively.

 

Most computers have 2  network cards so that one could be used for internal network (to transfer data fast between computers in the office) and the second network card only for internet - it's safer to not have those computers that store important files and documents connected directly to internet or to some device through which someone from Internet could access files.
