no, you could just go to system settings, and then network settings and click wireless and you can join into your wifi.
No you need wifi. 3G would not have enough bandwidth.
Have wifi connection
To my knowledge you cannot connect your xbox w/built in wifi to a dsl connection without a wifi converter
No it can not. you need a specific router to be able to use xbox live. It is possible to use an ethernet cable to connect to xbox live, or you could do what i do which is using my laptop as a connection bridge to connect to the xbox using wifi.
You need to connect it via ethernet or wireles (WiFi) connection to a broadband internet type. Then follow the on screen instructions to create a Gamertag.
The Xbox 360 has no built in WiFi adapter. Without it, the system would have no way to connect to a router to play over Xbox Live, without using a cable. The router is required to access the internet.
Yes, it is required to have some sort of internet connection so the internet connection can connect to their servers.
If you mean get it for free using your broadband, you can't! Unlike playstation 3 you have you pay for a subscription (i.e Xbox live) and then connect to your broadband to play. Once you paid for a Xbox live membership, just scan for nearby wifi connections and connect to your router (or anyones if they have no password)
You need to go to a place with WiFi connection or get WiFi connection where you live.
You have to have wifi i think. You should call your wifi supplier and check your connection.
No it can not. The Nintendo wifi usb adapter sends a signal that only Nintendo products meant to connect to wifi (such as the DS and the Wii) can pick up. Xbox and other products of that nature can not pick up on the wireless signal sent out by the usb adapter.
Yes, you only need to find a wireless connection and you can go on Xbox Live.
