Can you have more than one router connected to your modem?

Question

i have very slow internet and a slow router,but also have a faster router which is faster and has more range compared to our old one.the problem is our older computers won't connect to that router for some reason,and i want my computer and 360 to connect to the faster router and see if that helps with the slow internet somewhat.(help me get my full 1.5mbs...lol...and yes i plan on upgrading if my step-mom stops being a control freak and saying this is fast internet.)heres what i mean..

Answer 1

I have made that configuration work, but it is not stable, and when you have problems your ISP will not be able to help you

Answer 2

Use a switch for the older computers and plug that into one of your faster router ports (like its a computer).  Having 2 routers will give you headaches
