Does an Dual or Triple GB LAN Connectiond Make Your Internet Speed Faster

[HectiKCookiE]

So i was ripping apart my old hp rack mount server, why? mostly i just like to take things apart. and a saw it had a dual intel gigabit lan card so i pulled it out and stuck it into my PC. i didn't think there would be any real performance boost (unless i had a nas or something) but i did some testing results below.

 

1: Realtek gb LAN and 2 Intel gb LAN

2: Realtek gb LAN

3: Intel gb LAN

 

 

The extra LAN ports made no difference, would they be useful for anything i would do like gaming or streaming?

No it does not.

Adding more connections makes it REDUNDANT not STACK.

 

This means if one connection fails it will use the other, but it does not increase your internet speed becasue the ISP is limiting your connection. The amount of cables connecting your PC to your modem is not a bottleneck.

[thekeemo]

it only increases lan speed

[HectiKCookiE]

it only increases lan speed

 

yes, well i know that now

[HectiKCookiE]

No it does not.

I'm not a complete idiot i know that my isp limits my internet i just thought maybe my router shares it or something between the lan port, i thought if any thing it would be like 5% difference

No, all the LAN ports get full 1Gb connection (unless its a 100 router not 1000)

there should be 0 difference

it a netgear nighthawk so they are all 1000mb and i know there's performance boost i said that in the first post

[TheProfosist]

The other thing you could do which is something I plan on doing is to use one port for LAN and one for WAN.

there is no performance boost

all your results are the same within margin of error

 

when you use internet your computer chooses ONE network connection to use. It does not use both.

 

You can see this by going to task manager: network while running the speed test

only one network will be in use

i ment to right NO performance boost. as i stated in my first post

The most common reason to have multiple ethernet ports is to eliminate single point of failures by creating a redundant connection. Though bare in mind that most home routers/switches will not support doing this. One other use that might be more useful for you is if you have a NAS or other storage device that also have multiple network ports... then you can add a dedicated line to that device from your computer. That way accessing data on that will not affect your other network traffic.

Managed Switches and Link Aggregation can combine ports into "one pipe" but again you will not really see any benefits in a home networking situation. (your OS or drivers for the card also need to support Link aggregation to accomplish this.)

[flexin1981]

even bundling the links into one aggregated port would not increase the speed in this use case.

 

both redundant ports and things like ether-channels were designed to give either redundancy or a speed increase in a switching environment, not on a home/server machine.

In theory you could decrease your network latency by a teeny bit by switching to SFP network connections, rather than RJ45 -- SFP has lower network latency than RJ45. Your ISP is still the bottleneck for overall bandwidth, though.

Actually with the right NIC's and drivers you can do NIC teaming, as the name suggests the NIC's team up your PC sees it as one connection but its actually 2 or more physical, Although I know that most computers don't have this function, he said the card came from a server, So it may, with the right drivers, have this function. Im not trying to say your wrong. Im just trying to give you more knowledge, Obviously you are correct about the cable from the computer to the router not being a bottle neck

yes I know its possible, but even if he did do it it would not give ANY speed improvement at all because his internet speed is not over 1Gbps

Yes and I realize that as I mention in the post
