PC and 360 networking issues

[KermitM42]

so im running a netgear switch to divide up the internet between my roommates and i, and i noticed the other day that if my xbox and pc cannot be connected at the same time to the internet. like if im on xbox live ill have no internet connection, so ill repair the connection, renew the ip and it fixes it but then it drops me from live. it works both ways too.
any help or ideas would be great, thanks

you need a router, not just a switch, to share an internet connection.

you dont need a router to share internet. ive been doing it for some months now. i may need a router to handle the dhcp for using a 360 and a pc for some reason, but thats not it because i tried the router with it and it stll didnt work.

Who is providing your internet service? Do they allow more than one IP? If not you will most certainly need a router.

What were the symptoms when you used a router to "share" the internet connection? You could always call the provider as well.
