Thanks all for the input. We are just kind of straying from my original goal of particular information.
I just want to know if anyone has any pointers as to if:
1) a dedicated router will take over the router job from a combo modem/router on it's own after installation,
2) or if I need to disable the router part of the modem/router so the new router will be able to do the router job
3) or will I have to toss the modem/router and get another modem to be able to use the router.
obviously 1 is the best case scenario and requires no tinkering from me. But, in my time with computers, almost everything needs tinkering.
I can live with 2, but I was curious if anyone else has had to do this.
If 1 and 2 are impossible, and chucking my current setup altogether and getting 2 different pieces of hardware, then I likely won't bother changing anything.
Hitman mentioned a bridge mode. I have been through the setup and don't see anything that looks similar to that. I just want to do this research so I can make an informed decision on whether or not this is a project I want to tackle.
My current setup works. I want to try to make it work better if I can do it at a reasonable price, and use of my time. I don't plan on doing anything that will take food out of my kid's mouths. I just like to work on this stuff. I didn't have to spend hundreds of dollars over the last 3 years to build a bunch of computers to do folding, but I wanted to.
