Connection teaming advice needed

Hello-

I have cable modem installed here, and with the way they have their system setup, we are allowed to have upto 3 computers connect to their network and each computer (upto 3) will be assigned an IP from the DHCP server. So, tinkered a little bit and noticed that when I put two NICs in one computer, they were each assigned an IP. I tried to make it so that that computer would be able to use both connections at once and sort of 'multilink' like the shotgun modems used to. I wasn't able to make it work with what I know and my Windows98 so research came up with what is called 'connection teaming'. Here is a link to a company that seems to do it and do it well:
Midcore's rendition to connection teaming

So, I installed it and did what little configuring it requested and the connection appears to not be any faster than before, sometimes a bit slower. DSLreports speed tests come up with the same rates with some tests coming back really crappy. Not sure why on the bad tests.

So my question is just to see if anyone has succeeded in teaming broadband connections and if so - could I get any pointers. Maybe there is a better OS for connection teaming? I would be willing to consider upgrading to another OS or program to manage it to make this possible.

Thanks for your help-

You're really not going to get much more performance from teamed NIC's. They, in fact, add some CPU time and require some extra processing for each packet, so you've got more overhead.

Assume you've got a cable modem. MAX you'd ever see from it is 3Mb/s. I've heard of really rare ISP's that get faster, but not many. If you have a 100Mb/s NIC, you're already 33X the performance of your Internet connection. Also, most ISP's limit upstream speeds to 128Kb/s - 1/800th the speed of your 100Mb/s NIC.

So, you really don't gain anything using a 2nd NIC, actually just the opposite.

Well, here's what I am thinking though. Let's say I have two computers, each with 1 nic connected into the cable modem's pipe. Each computer's adapter is given an IP address from the DHCP server and each computer is rated at DSLreports.com's speedtest to be getting the paid for speed rating of around 768k down and 128k up.

So, if you take those same adapters and put them in ONE machine, team the connections together - they should run close to double speed (minus TCPip overhead), right?

Otherwise, what is the point of teaming the connections? It works for multilinking shotgun modems, right?

I fyou test them both simultaneously at DSLreports, each will get half that number. You ISP is limiting you by the whole line, not by each machine. They may be giving you 3 IPs but they arent giving you 3 times the bandwidth if you use all three IPs.
