how to setup 2 internet connections on one pc

February 24, 2011 at 15:20:30
Specs: Windows 7
I have a DSL line and a Cable line. Cable line is 30mb, DSL is only 6 mb.

MY PC has 2 NICs: cable modem is connected to ethernet NIC, DSL is connected via wireless nic.

So, my question is, when I have both NICs enabled, which one does windows use ?

does it use both via load balancing ?

When I do a speed test with BOTH NICs enabled: My speed is 15 mb.

When I do a speed test with ONLY ethernet NIC (cable). my speed is: 30 mb.

So, what gives ?

Is Windows even able to load balance between gateways? As far as I know it determines which gateway to rout through by the metric setting. If it is automatic it will use the gateway with the lowest metric (fastest one) over another. To see which gateway you are routing through use of TRACERT and send it to us.

I read an article on MS site that said to change the metric for both adapters to the lowest setting in order to force windows to use BOTH connections simultaneously.

Problem is, that article was for windows 2000...and I cannot find that setting on windows 7.

I tried command "tracert" but it's asking me to enter a command after tracert.
(i.e. tracert -d, tracert -h etc.) It returns the help menu when I type only "tracert"

What command do you want me to run ?

I have both NICs enabled.

I set the metric on IPV6 TCIP to 1 for both.

Here is tracert

When I run a speed test, I find that my download is at 30mb with wifi nic (dsl) disabled.

When I enable the DSL nic along with the ethernet nic (cable).. my speed drops to 15mb.

What gives? I thought it would load balance ??

You need a Server Operating System.....................

Load balance?

NLB is in clustered servers
adapter teaming can be done with software

You need a dual wan port router. Windows can't do this for you.

"1 <1 ms <1 ms <1 ms"

You are going through that gateway. When you disable the NIC and do a trace route you will see that you are going through the other gateway. You can not load balance with Windows as far as I know. Even if you could I think you misunderstand what load balancing will do for you. It just sends packets to the other gateway when the primary is busy. It determines this through metrics.

Even when you get load balancing going you will never get a connection that is any faster than you fastest. I think what you are looking for is teaming. If you team the NICs then you might get the results you are looking for but I have only ever used teaming NICs on a LAN not a WAN so I have no idea how it would work in a WAN environment.

This may help...

Hey guys.

My objective is NOT load balancing. Sorry if that is not clear in my earlier posts.

My objective is fail over.

So, when I have both Ethernet and Wireless NICs enabled.... do I have a fail over setup?

ie. if my cable isp goes down... will I notice a drop in internet connectivity? (ie. surfing web or using internet based games)
