help with dual internet connections on one mobo

post #1 of 7
Thread Starter 
Sorry if its not the right term to use but I don't know what to call it when you use both internet connections offered on some higher end motherboards.

I have had this system for some time now but until yesterday had never bothered to plug two Ethernet cables connections on my motherboard. At the time I was using Utorrent and DL a 26gb file @ 1.4kbps and it was going to take around 2y to get. After pluging in the second cable and attaching it to the router I jumped to 250-500kbps / 2 days complete.

I was really shocked to see it improve my speeds for Dl-ing biggrin.gif I started to wonder if there were any other settings I should be looking at for even more speed. This is all new to me, I have no clue were to start or even what to look for. My router is very good ... imo (Cisco wrt 610n) and have never had an issue with it. DMZ and all that jazz I think was set up on it but I may need to make sure .. ill need a hand with that also. I think most of the settings for best performance are just check box style other than port forwarding which is beyond me. The router has a PC with dual internet cables, Smart TV, PS3 hardwired to it and two cell phones and a laptop which use the wifi on the router.

Win8 drivers for the mobo have been installed and the most current offered ... I think, tongue.gif Is this stuff to the point of plug and play or can I get MORE from tweaking.


Thanks all

Teaming is the term for multiple cables. But proper teaming like what you are thinking of requires multiple connections to the isp. With only one main line coming into your house you can plug in 50 lines to your computer and the speed won't change. I'm guessing something might be wrong with the cable on the first one, or pure coincedence that you got a better connection on the torrent at the same time.

*EDIT* PhilWrir below me more likely right. I am not a networking guru.

There are little tweaks you can do to improve ping slightly, some hacks to the modem to allow a faster connection speed but generally you can't speed up your internet connection without violating a user agreement from what I've seen. The hacks to the modem are on the same level as cutting into the electric lines before they go through the meter to get free power. They can bust you for it if they find out about it. At least where I live.

In my experience its more likely that one port is using a realtek or broadcom NIC and the other one is using an Intel NIC.

I don't think connecting more than one NIC into the router would boost internet download speeds. You are still limited by the modem and what not.

The most likely reason why the torrenting speed jumped after plugging in the second NIC is because it takes time for Utorrent to find more seeders. You just happened to plug in the second NIC when it found the extra seeders to increase the available bandwidth.

The main purpose of having multiple NICs on the board is so that you can connect with certain devices that use ethernet to connect to the computer/network.

It also works if you want to use your computer as a router where you would hook up one port to the modem and the other to a network switch which then goes into the network.

Another use would be for daisy-chaining multiple 2-NIC boards together into a cluster. This would eliminate then need for a switch.

The only times I've seen benefits from using two NICs over one is when you need more bandwidth than gigabit ethernet can offer. Using two effectively doubles that.

Then again that is all restricted to local networking.

thanks for the input everyone thumb.gif

TEST A
Over the day I have been doing some switching of the cables to see what would happen. I was holding steady around 310kb/s with two lines in. Removing the upper cable (lowest connection running only) I dropped to 1.04kb/s and even plugging the upper cable back in the DL did not recover to its original speed. Unplugging the lower cable returned me to the original speed but plugging it back in reduced me to 204kb/s. I switched cables around and reran the test.

TEST B
Upper connection only with (cables reversed from test A) was 205kb/s both plugged in 309kb/s. With the lowest connection (cables reversed from test A) working only I get 152kb/s. Plugging them both in again nets me 500kb/s

Two things I see here ... three actually

First my lowest connection is slower. Second, two connections are faster than one (when working properly) and lastly there is an order to connecting the cables to maximize the speed. Upper cable plugged in first and lower cable second seems to keeps speeds from "capping"

So what does this tell you ... I don't know my head hurts just reading this lol. I may test ports in the router tomorrow and see if that has any bearing.

Windows doesn't use two LAN connections together, so I would do all testing with just one plugged in.

Then I would have to say my top connection is faster than my bottom connection thumb.gif

How is it that both connections to the same router is quicker than on connection by itself?
