1. my dsl modem is the main gateway 2. a switch connects to the the modem 3. a broadband router connects to the switch 4. a wireless router connects to the broadband router *Exception: wireless router can't be configured to connect to modem nor switch only through the broadband router. *most of the computers in my house connect to the wireless router wirelessly since they are located to far to have a wired connection and also the wireless roouter has better security features. *the broadband router (wired) is used to connect game devices such as XBOX's, and PS2's s. This router has better features for gaming because of its ability to customize ports for forwarding, DMZ, etc. Issue: Now I would like to know that eliminating some devices like the switch help increase bandwidth and decrease collision domains? The switch is just used to connect to the modems local ip address and gain control of its interfaces.
