Use a CAT-5, also known as an Ethernet cable.
Straight cable
An Ethernet cord
usually an rj45 cable
straight through cable
You can use any cat 5 ethernet cable to connect the xbox 360 to the router.
To connect to a cisco 1800 series router, you need either a network connection that goes to the router, and then you would configure the router to allow telnet or you would need a console cable, also called a rollover or cisco cable and physical access to the device.
A normal crossed ethernet cable will do.
It would connect to the serial port interface of a router.
To connect two devices of the same type together. e.g. You would use a crossover cable to connect a router to another router, a switch to another switch or a computer to another computer. If you are connecting diferent devices together, such as a router to a switch, a straight through cable should be used.
A rollover cable is used in a networking environment where a router/switch is to be configured from a computer. One end is wired one way but on the other it is reversed. You would typically use one end into a serial port on a PC and the other into the console port of the switch/router. It is common within cisco configurations. Hope I helped
No. Your computer would connect directly to the cable modem via an ethernet cable.
Crossover
The question would be easier to answer if you included the specific model # of the Netgear router you are trying to configure. You can not connect a netgear router or any other router directly to a DSL line unless it also functions as a DSL modem. You can connect a router to a DSL modem which connects to a DSL line.
Rollover
cat 5 Ethernet cable
You add a wireless router to your cable modem and you're in business. The router can run from $50 to $120 and you need an Ethernet cable to connect the devices
